It’s never too late to learn something new and this is a key theme of the September Pro Arb, where we have a range of insightful articles to boost your knowledge... all in your coffee break.
Take ash dieback – the disease has reached epidemic proportions and is creating huge amounts of work for arborists, although the demise of these trees is an ecological disaster. So, many will be encouraged to hear a solution may be found in the tree’s DNA – check out the interview with Professor Richard Buggs from the Royal Botanic Gardens Kew on page 14.
On page 18, there is another excellent piece from Dr Duncan Slater, where he looks at the risk to trees when tools are in the wrong hands – it is a timely reminder to check inexperienced staff are properly supervised.
If you are looking to widen your understanding of trees and fancy a foray into forestry, then why not attend the forthcoming Confor Woodland Show? We have a preview of the event – to be held on 21-22 September –on page 12.
Then there are kit pages galore, starting from page 24. Whether it’s a wood chipper, a portable saw-mill or some survey equipment, there are pages of temptation, We also have some top tips on chainsaw maintenance from Stihl – what more could you want? Enjoy the issue.

Analysis from Friends of the Earth has found areas with fewer trees and green spaces were up to five degrees warmer during the UK’s hottest days. New heat maps from five English cities showed tree cover plays a significant part in reducing temperatures. Friends of the Earth is now calling on the government to ensure streets have at least 20% tree cover in urban areas and to protect trees from felling to reduce the impact of climate change. The maps were produced by TerraSulis on behalf of Friends of the Earth and were of London, Manchester, Birmingham, Bristol and Newcastle. This is the first time the combined effects of trees on built up areas has been modelled.
Last July, a new record temperature was recorded of 40.3 degrees Celsius in Coningsby, Lincolnshire. The analysis showed marginalised communities are most impacted by the climate crisis, including those on lower incomes and air pollution is also worse in the hottest areas.
Some 43% of English neighbourhoods have less than 10% tree cover, while over a third lack adequate access to green space. Mike Childs, head of science, policy and research at Friends
of the Earth, said: “It’s remarkable to see such a striking visual representation of the cooling power of trees and green spaces in our towns and cities. Our mapping shows that access to green spaces provided welcome cooling of up to five degrees on last year’s hottest day. We know extreme weather, including heatwaves, is now becoming more frequent and severe due to the climate crisis.
“Boosting tree numbers is such a clear win for our communities and our planet, not just because of their ability to cool urban
areas, but because they capture planetwarming carbon too. This should be prioritised alongside a rapid programme of council-led, street-by-street insulation, which helps keep homes cool in the summer just as much as it keeps them warmer in winter.” friendsoftheearth.uk
was launched in 2021. Tubex’s partnership programme now extends to Maydencroft, Green-Tech and British Hardwood Tree Nursery. They have set up hubs, to join those already launched by Tubex’s parent company Berry Global; these are Yorkshire Dales Millennium Trust, National Trust and Tillhill.
Tree protection provider Tubex is expanding its collection and recycling programme. Tubex runs a network of drop-off hubs for the collection and recycling of used tree shelters, which has increased to 17 up from 14. Businesses can bring end of life tree shelters to the hubs, dropping them off free of charge.
Tubex reported many of the drop-off dates have filled up, with hundreds of thousands of shelters already collected. The total shelters collected in 2023 is double that of 2022.
“Taking old shelters out of the wild and recycling them is the most sustainable form of tree protection long-term, as indicated by independent life cycle analysis,” said James Taylor, product line director at Tubex.
The hub network was launched at the end of the 2022-23 season, to complement the existing means of collection via site pick-up, which
Landscape management consultancy company Maydencroft opened a hub at its base in Letchworth Garden City. According tree planting and aftercare manager, Chris Beer: “Not only do we have a route to remove and properly dispose of existing guards found across many sites, we can offer our clients this circular economy of recycling from the start, all as part of a planting and maintenance package.”
Taylor added: “We’re always happy to welcome new partners, whether you have the facility to accept shelters for one weekend or many months. See Tubex’s site for more details: tubex.com
The company behind vibration monitoring solution, HAVSPRO, has reported 3,000 workers are benefiting from the technology. This offers accurate, realtime monitoring of workplace vibration. Sixis Technology said a variety of sectors (including arboriculture) were using it to manage the risk of Hand Arm Vibration Syndrome to as low as reasonably practicable.
Russ Langthorne, managing director of Sixis Technology, said: “As HAVSPRO’s accurate technology is rigidly fitted directly onto a worker’s tool, it can measure real-time vibration exposure. When you combine this with the proactive alerts, employers and operatives can act before over-exposure occurs. The in-depth reporting also provides evidence in the face of litigation claims.
A report has revealed that the government’s aim to plant 30,000 ha of woodland by March 2025 is unlikely to be reached; less than half of the target in England has been met. DEFRA produced this nature target – a requirement under the Environment Act. But, a report by the Environmental Audit Committee (EAC) of crossparty MPs said there was still a long way to go.
While the public sector is responsible for only a quarter of UK woodland, the report found there was not enough direction from the government for the private sector, which faces “unclear strategies and bureaucratic schemes”.
The EAC report also said UK-sourced timber will help meet the growing demand for low-carbon construction materials. It added
a significant expansion of woodland cover is required to compensate for predicted shortfalls in the supply of domestically produced softwood timber and to deliver the UK’s climate goals.
The committee said it was “disappointed to observe Forestry England is not currently on track to contribute fully to national tree-planting targets.” EAC chair, Philip Dunne, added: “There are too many overlapping strategies that aim to cover tree-planting policies in the UK. The numerous strategies are disjointed: what is required is an overarching, holistic strategy that sets a long-term vision for how different types of woodland will be used to deliver the government’s goals.” committees.parliament.uk
“The detailed reporting guides managers and team leaders through the process of positively identifying where the risks are emanating. With the vast amount of accurate information available, there is now no reason for companies not to be tackling this pervasive problem. As we see more tools hitting the market, some with better vibration control than others, we harbour concern some businesses may not be protecting their employees or businesses as robustly as they think.”
In the UK, there are an apparent two million people at risk, and 300,000 people who suffer from HAVS. Companies are also facing rising litigation risks, with fines totalling £2.5m in the last seven years. havspro.com
More than 400,000 trees have died within years of being planted by National Highways. The saplings were in place to compensate for road projects in England and the figure was revealed following a freedom of information request by The Times. It was said the deaths occurred because of a lack of aftercare. The report said the government provided data for only nine of its 38 large road projects and so the true figure is likely to be much higher.
One example is at Chowns Mill A45/A6 junction at Higham Ferrers, Northamptonshire. Conservative MPs Peter Bone and Tom Pursglove attended a ceremony less than two years ago to mark the planting of the final few of about 2,500 saplings. However, three quarters of the total planted have now died. The rate was the worst of the nine schemes National Highways provided data for; of 945,000 trees planted by the company since 2018, at least 405,000 have died.
Meanwhile, some 45% of 860,000 trees along a new stretch of the A14 in
Cambridgeshire died while being established. They were planted at the end of the 2020 planting season, shortly before country went into drought. Liberal Democrat councillor Ros Hathorn, who lives close to the A14, said: “When a community walks past dead trees every day they tend to make a noise. My worry is: what is happening in the places people aren’t walking past? Motorway verges feel like no man’s land. If no one thinks it is theirs and is fighting for biodiversity, what is happening there?”
National Highways has said it will replant the trees, starting in the planting season from this October. Another Liberal Democrat councillor, Edna Murphy, said: “We want National Highways to apply the learning to all their other projects and to make this information available to the public.”
John Parker, chief executive of the Arboricultural Association, said projects should be planned for maximum survival, rather than the maximum number of trees planted. “These figures reaffirm that the focus still needs to move further towards tree establishment than planting, looking at ensuring maintenance and tree aftercare plans are in place for such projects.”

Russell Abrahams, 62, from Aldeburgh, Suffolk, has been fined £5,500 for illegally felling an oak tree in his garden. He was sentenced by magistrates after pleading guilty to breaching a 34-year-old preservation order that had been placed on the oak, in his garden in Thorpe Road last summer.
The prosecution was brought under the Town and Country Planning Act 1990 by East Suffolk Council, successor to Suffolk Coastal District Council, which approved the original Tree Preservation Order (TPO) in June 1989. The prosecution was brought under the Town and Country Planning Act 1990 by East Suffolk Council, which approved the original Tree Preservation Order (TPO) in June 1989.

Although a tree works application had been submitted to East Suffolk Council in December 2020, it only covered work to a number of grey poplars area and the removal of a rotting sycamore. But, it made no reference to a healthy, maturing Turkey oak felled nine days before the officer’s visit.
Abrahams appeared before magistrates on 19 June to admit breaching the preservation order. He was fined £5,500 and ordered to pay £1,302 in prosecution costs and a £2,000 statutory court surcharge.
A tree replacement notice will also be issued by East Suffolk Council, requiring the planting of a replacement Turkey oak in a position adjacent to the location of the felled tree. Councillor Kay Yule, East Suffolk’s cabinet member for planning and coastal management said: “I hope this prosecution and the resulting sentence serve as a strong reminder that anyone considering work on protected trees must follow the correct processes.”

The Confor Woodland Show will take place at the Bath & West Showground on 21 and 22 September, a two-day event that focuses on hot topics, the latest machinery, forestry research and the opportunities for future growth.
There will be key people from the forestry and timber sectors and plenty of practical advice from demos and seminars as well as networking. It could well provide plenty of food for thought for arborists who may be involved in larger contracts, are producing timber or simply thinking about using heavier kit. There will also be a number of specialists on hand to discuss opportunities within forestry and simply to provide more information on what it offers.
Confor is the Confederation of Forest Industries, the trade association for the forestry industry in the UK – and it represents forestry and wood-using businesses, including nurseries and growers as well as wood processing end-users.
The Confor tent will be the central hub of the event and will be the venue for some big discussions on issues such as agroforestry, bioplastics, trends in the forest marketplace, and modern management techniques. Speakers include representatives from Defra, Forest Research, FSC UK, Rainbow Professional, CSX Carbon among others.
Bigger and better Richard Hunter, Confor’s technical and industry support manager, says: “After a four-year break, it’s great to have the Confor Woodland Show retaking its place in the sector’s calendar. With a move to the Bath & West Showground, we hope that our members and colleagues from across the industry will agree the show has returned bigger and better than before.
“Everyone at Confor is excited to welcome old and new faces back in September. We are immensely grateful
THERE’S PLENTY OF CROSSOVER BETWEEN FORESTRY AND ARBORICULTURE AND THE BEST PLACE TO DISCOVER THE DIFFERENCES AND SIMILARITIES IS AT THIS EXCITING EVENT THAT WILL BE TAKING PLACE IN SEPTEMBER

to our sponsors and exhibitors for making our excellent programme of discussions, panels and demonstrations possible.”
He continues: “This is an extremely important time for forestry in the UK. The benefits that woodlands, forestry and timber can provide for the economy, for rural communities, and for the mitigation of climate change present unique challenges and opportunities for the sector. Bringing leaders in the industry together to share knowledge and ideas is now more important than ever.”
Visitor attractions include machine demonstrations, live chainsaw carving and archery as well as a range of food and refreshments on offer. Meanwhile, the Forest Workers Zone will act as a one stop hive of activity for those working in the practical side of the industry with information, advice and networking on offer. Experts will be holding practical demonstrations on skills such as chainsaw maintenance and tips for safe use, as well as being on hand to answer questions.
The Bath & West Showground is at Shepton Mallet, Somerset BA4 6QN – it can be found just off the A37 and drivers should use postcode BA4 6ST to arrive at the correct gate for parking. The nearest train station is Castle Cary, which is four miles from the venue, Bruton and Gillingham stations are also relatively close.

Bringing leaders in the industry together to share knowledge and ideas is now more important than ever
Experts at the Royal Botanic Gardens, Kew are researching tree DNA to try and find a resistant strain that will replace the millions of trees lost to ash dieback. The fungal disease Hymenoscyphus fraxineus (or Chalara) is already resulting in tens of thousands of trees being felled across the UK. This is creating plenty of regular work for arborists, but many who are involved in this work will find it a bittersweet experience – earnings may be boosted but there are also serious consequence for nature. Ash fulfils a unique role and supports 955 species, 45 of which only use ash while 62 of these are highly associated with ash, meaning they rarely use any other tree species. There is also an impact on the ground – ash trees cast a light shade because of their delicate leaves meaning many species can grow beneath it and this will change if other trees are planted or if the land is left bare.
The fungus originated in Asia and has proved devastating to ash trees across Europe and the UK as the species have no natural defence against it.
But, work is underway at the Millennium Seed Bank (MSB) laboratory at Wakehurst; this is a site that covers 500 acres, owned by the National Trust and managed by the Royal
ash dieback.” There are predictions that up to 80% of the species could be lost and in the UK that is some 160 million or around 10% of woodlands.
Botanic Gardens, Kew. Professor Richard Buggs explains: “Ashes are the third most common trees in the British landscape, but millions are now affected by the fungus causing
Professor Buggs is senior research leader for the Royal Botanic Gardens, Kew and also professor of evolutionary genomics at Queen Mary University of London. He explains the research work is also focused on the emerald ash borer, which is found in Asia and North America. This is a beetle that has not yet found its way into Europe or the UK, but is considered a further serious danger to ash trees.
“We are analysing ash genomes to find genes to overcome these threats. We are preserving native genetic variation of UK ash

in the MSB. Our Kew Science project is not exclusive to the MSB, but we do however, have a stock of ash seeds from across Britain secured in the MSB vaults.”
One of the techniques being used is DNA analysis, and professor Buggs comments: “It’s only recently that DNA sequencing has become cost-efficient to make it feasible to sequence the DNA of enough trees. This makes it possible to look for genes associated with resistance to a disease and it’s a new area for forestry and
genetic modification to reduce the generation time of ash so that we can accelerate breeding for a few generations, then remove the transgenes so we have a non-GM tree that has been bred rapidly.”
arboriculture. Research of this nature has been done in humans and crops for longer, as more funding is available in these areas.”
In addition to ash, analysis of oak and birch DNA is taking place as they also face disease threats. The Wakehurst research is a Britishled project, although professor Buggs explains there is lots of research on ash going on elsewhere in Europe. “The UK is leading on the genomics of ash dieback resistance, but other countries are further ahead on the pathology and selection programmes. A particularly big selection programme is underway in Austria.”
Selection involves finding ash dieback resistant species to replace all those that are lost, but this is certainly no overnight fix, and so the current project aims to speed matters up. Professor Buggs says: “If several generations of breeding are needed, this could take many decades. We are seeking funding to use
He adds this is the most encouraging development to date, since the decade or so when the disease was first discovered – this was in 2012 when infected ash plants were sent from the Netherlands to a nursery in Buckinghamshire.
There have been reports some ash trees may already be resistant to the fungus. Professor Buggs comments: “Some ash trees are remaining healthy even though many trees around them are badly hit. However, in many cases this is not because the trees have complete genetic resistance but because they have partial resistance and are in a favourable micro-environment. When cuttings have been taken from such trees and placed into trials, they have often been affected by the disease.”
replanting will be needed. Lots of trees are clinging on in woodlands and producing natural regeneration that is being naturally screened for increased ash dieback resistance. We can help that process along by planting out more resistant trees into the landscape to contribute pollen and seed. If we had ash trees with complete resistance, these could be planted again for commercial forestry, as street trees; currently we can’t plant ash for these purposes.”
So, what about fungicides? Professor Buggs says that treatment with several common fungicides can take place, but spraying toxic chemicals is not the solution – the disease is too widespread and he points out that “treatment of natural woodlands with broad spectrum fungicides would be harmful to many beneficial fungal species.”
So, a resistant species makes far more sense and there is also help that the UK’s expertise in this area could benefit other countries too. As professor Buggs says: “We already have a lot of interest from scientists in Europe who want to use our genetic markers to develop their own resistant trees, locally adapted to their own climates.”
These trees may be able to live many years however, and he says: “I don’t think complete
It may be difficult for arborists that need to advise clients that the only solution is to fell an ash; as the disease progresses, branches can become brittle and the tree can pose a hazard. But, at least now there is some hope that thanks to the work of professor Buggs and colleagues, that there will remain an ash presence long into the future.
It’s only recently that DNA sequencing has become cost-efficient to make it feasible
Last year a sample arrived on my desk, labelled “Unidentified alien organism”. It sure was something unusual as inside the bag was a piece of bark bristled all over with what looked like tiny blue-black mushrooms. They had spherical heads and a tough woody texture – it was like one half of some kind of organic velcro.
One of our consultants at Bartlett Tree Experts, Bruce Hauxwell, had found this ‘alien’ in Essex during a structural survey. It was filling a depression in a churchyard yew stem. The photos he sent before the samples were striking and it would have been hard to miss if you were paying any attention to the tree.
Getting the sample under the microscope didn’t help much; it was rock hard but I managed to get some spores out. This didn’t tell me much, but reminded me of lichen spores (lichens are a symbiosis of a fungus and a photosynthetic algae/cyanobacteria).
I was puzzled, so forwarded photos to my US colleague Dr Andrew Loyd. He is a plant pathologist and suggested it could be a pin
lichen. I guessed the genera Chaenotheca or Calicium, which looked similar in shape but didn’t seem to occur in such dense colonies usually.
Everyone was already happy that this wasn’t something impacting the tree, so we left the identification there. Then in June this year, another sample turned up from near York, sent by our local arborist representative, Jim Philpott. Again, it was filling a deep rut on a yew stem but was a bit softer, fresher, and darker.
This re-sparked my interest and I sought to learn more about this organism, partly to ensure we weren’t disturbing something rare. So, I posted photos on a forum for fungi and lichen enthusiasts (www.fungi.org.uk).
After some initial confusion, as this apparently was like no lichen or associated fungus most had seen previously, Dr Paul Cannon, emeritus mycologist at Kew Gardens, thankfully came forward with the answer.
This was not a pin lichen at all but a fungus from a genus historically confused with them: Chaenothecopsis caespitosa. It is much larger and denser than the other members
of its genus occurring in the UK and feeds on exudates (sap runs) produced by yew trees, such as those from wounding or pruning.
Only certain members of the genus feed on exudates and research indicates that those consuming conifer exudates may have evolved tens of millions of years ago. Other members of this varied genus feed on deadwood or parasitise lichens or bracket fungi.
While Chaenothecopsis caespitosa is not thought to be particularly uncommon, it is likely under-recorded, so please get in touch if you find any more by contacting us at: diagnostics@bartlettuk.com

As a child, I was lucky to have relatively unlimited access to a wide range of hand tools and a woodland area to use them in. But, as I started to take an interest in trees and went into arboriculture as a ‘groundie’ in my late teens, I progressively took my ‘tickets’ and learnt a lot by doing so. This was rather than working on trees based on my childhood experiences. This is the recommended route to becoming a skilled arborist – in-depth training and accreditation, accompanied
and followed up with extensive experience –according to the Arboricultural Association. You can, however, take on a basic operative role in grounds maintenance or tree care without having much experience or training to start with – and perhaps never ending up with NPTC ‘tickets’ or other recognised accreditations. On the positive side, our industry is easy to enter; on the negative side, relatively untrained personnel are often going to be doing bad things with good tools.
Of all the things killing amenity trees, the misuse of grass strimmers – or ‘weed whackers’, as they are commonly called in the US – must be one of the most frequent and most depressing ways in which young and newly planted trees die.
I get to see this very often, and I know many other arboriculturists do too. Often, it is ‘repeat business’ that finishes off a young tree. Amenity grass is often cut 10-15 times a year, so just a few of such visits where there is some nicking and notching of the base of a small tree, and that will be enough to cause dysfunction and then death.
Those wielding a grass strimmer need to resist the temptation to cut every blade
Hedge
You would think that a simple rule, such as not to cut scale-needled conifer hedges ‘into the brown’, would be an easy thing to understand; however, I’ve seen too many instances where ‘Ignorance + hedge trimmer/chainsaw = death of a conifer hedge’. Some examples I have seen are shaped and pruned quite proficiently – so the operator had good cutting skills – but what they clearly lacked was the knowledge that there is no coming back for such conifers (such as Chamaecyparis, X Cuprocyparis and Thuja) if they are pruned in this way.
Strimmer guards are a quick and easy fix, while establishing and maintaining a mulch circle around the tree’s base is better as it provides multiple benefits. Putting in some form of more permanent barrier to prevent grass-cutting equipment ever being able to come close to the tree’s base might also be the best insurance against it happening.
of grass, right up to the tree’s stem, to make such a site ‘look tidy’. They need an understanding that trees are very vulnerable to such damage, as most of the life in the stem of a tree lies just underneath the outer bark, within the inner bark.
It is literally in our hands whether this sort of damage occurs – or not. Trees can recover from the damage caused by mower and strimmer damage and there are some obvious solutions to prevent it happening in the first place and providing a better growing environment for the trees too.
Unlike a strimmer or a mower, if you are using a chainsaw on someone else’s land for monetary gain in the UK, having a ticket (namely NPTC 201/202 and previously CS 30/31) is kind of expected. However, as far as I know, it is not a mandatory legal requirement. There is a large suite of such tickets available and some are less popular for those entering the industry, particularly the pruning ticket – NPTC 302 (previously CS 40).
Essentially, a lot of trainees stop at NPTC 308 (previously CS 39) – ‘using a chainsaw from a rope and harness’ –and so, how they use that chainsaw up in a tree varies considerably – one
arborist’s ‘pruning’ of a tree can be much more drastic than another’s.
In the northwest of England, the chainsaw is often a tool found in the wrong hands, when it comes to tree pruning, as my ever-extending library of images of poorly pruned trees attests to. In some ways, it is unfortunate that established trees are so resilient. They can get treated poorly but will seem, to the layperson, to still be in reasonable health, quite some time after such a brutal ‘attack’.
Looking at it the other way around, though, if trees were not so resilient then even more of them would be dying off more quickly, due to how prevalent these poor practices are.
14 years later...
Unfortunately, our new tree plantings face a substantial number of challenges, but at least, poor use of the tools, is solvable. It is often touted that the answer to all this unnecessary damage to publicly owned amenity trees is ‘Education, Education, Education’.
Undoubtedly this can help and it means firstly, education in the correct use of these tools secondly, education in how trees are vulnerable to wounding and poor pruning and thirdly, more general education about having respect for the environment, community spaces, and why one should do such maintenance tasks to the best of one’s abilities.
However, we’ve been trying the use of education to solve this problem for several decades now – and this problem has not gone away – if anything, it is worse. Perhaps, as with a lot of things, we need ‘money to talk’ – and we could establish penalties and enforcement for poor performance by greenspace contractors, if their actions lead to the death or damage to public assets, such as new urban trees that are much needed by our communities.
Another approach is to revisit those tickets, ensuring the training involving these tools requires a clear demonstration by the candidate that they are aware of the damage that can be caused by them. They should also demonstrate they can also carry out good practice in the field. It is a bit like the theory and practical one must go through to gain a UK driving license. It may seem excessive to put someone through this sort of training just to cut the grass or to prune a tree – but with probably thousands of trees dying from these problems each year in the UK alone, it is surely worth trying something different. Most would agree it is insanity to do the same thing over and over again and then to expect different results.

Dan Whiteman has always loved nature and is a passionate believer in the benefits of tree planting – he is now combining this with his day job and on a significant scale.
As a data management specialist, he explains: “I used to be the person who compiled the top 40 music chart on a Sunday morning and I’d be the first in the country to know who was number one. I then went on to specialise in databases forming my own data processing business, Oblong UK, in 2006.”
Alongside the business, Whiteman also runs Oblong Trees, which was launched in 2019 because he wanted to mitigate his firm’s own carbon footprint. “I tried carbon calculators and they gave varied results, so I looked into international carbon credits and didn’t trust them – I couldn’t find a solution I was happy with.”
Eventually, he found some international organisations that were planting trees to help wildlife, reforestation and communities. “I made sure no carbon was being certified from these trees, as there is a lot of ‘double counting’
person to pay to plant a tree, thinking they have done something great for the environment and then later certified carbon is sold from the same tree.”
Whiteman has also supported trees being planted in North America to help clean up the rivers, which boosts the salmon population, and in turn feeds the struggling orca population as well as trees being planted in Australia to connect koala habitats, allowing them to travel more safely. “As I bring on more international planters, I’ll be looking for them to be helping wildlife and communities – it isn’t just about planting trees.”
In the UK, Oblong Trees plants mostly native trees and on private non-farmed land and he explains that planting is only part of the work.
Around half his time is spent working on Oblong Trees, which he does unpaid. “The other half is running the data business. I also work weekends planting and looking after the trees. It’s not just a question of planting trees, I have to get the funding. Just to get funding to plant 10 trees might require an hour of talking to someone to gain their trust, then there is the admin on top. I also need to prepare the land for trees. Then there is the aftercare – watering the trees through long dry spells. I’ve got a growing number of volunteers, they keep me going and I couldn’t do it without them.”
He finds as more become aware of the record-breaking temperatures and other shifts in weather patterns they want to help out.
going on.” ‘Double counting’ is where a carbon credit is being claimed by more than one party.
“I didn’t want my trees to count towards anything else and it’s quite common for one
“I spend time looking after the trees, doing everything I can for each tree to survive; and so far my survival rates are very good despite the heat of last year and the long dry June this year.”
He is, though, more than willing to be handson. “Initially I hadn’t expected to be planting trees in the UK myself. I thought I could use existing organisations, but either their price
As I bring on more international planters, I’ll be looking for them to be helping wildlife and communities – it isn’t just about planting trees
was too high, or they would double count trees – raising certified carbon from them later – or they didn’t consider biodiversity. So in the end, I started planting trees myself, mostly on private land – spaces that really aren’t being used for anything. I would say there is land available to plant tens of millions of trees in the UK without taking up valuable land used for production.”
Whiteman has always been environmentally conscious. “I’ve only ever flown in a plane three times and I’m also vegetarian. Back in the late 1980s, I remember watching a video in geography, showing the devastation in the
“I’m also looking at certified carbon and biodiversity projects for larger companies – running a 10 year plan for companies costs just £2 per employee a month and this works out as 240 trees per employee over 10 years. So a company with 10 employees would fund the planting of 2,400 trees.
“It’s all based on the Climate Change Committee stating the UK would need to plant 1.5 billion trees to achieve carbon neutral. If every UK private company joined my 10 year plan, then we’d fund the planting of over six billion trees. My method avoids carbon calculations and just allows companies to make a difference depending on their size – I tell them to plant more if they are a heavy polluter.”
amphibians and reptiles, and give up space to a local bee-keeper. This would hopefully be the first of many such projects.”
Amazon with the equivalent of thousands of football pitches being cleared every day. Over 30 years on, we’re still causing mass destruction around the world and are not helping it heal fast enough. It’s not just climate change though, we need to keep our biodiversity.”
He explains he is also largely self taught. “I wouldn’t say I’m an expert and have been on a steep learning curve. I read everything I possibly could and then tried different things and I also speak to a lot of people who also have their own experience.”
Currently, Oblong Trees is not registered as a charity, but this is planned for the future. “Trust is a big issue, not just for me, but the whole industry and becoming a registered charity would help gain that. It would also open up more funding opportunities.” He also says at present Oblong Trees makes a loss and no one is paid. “I need to balance the books before registering as a charity. The plan is to continue planting trees, for non-certified carbon/biodiversity, and also to run projects that produce certified carbon, which I’ll run at a small profit enabling me to take on staff.”
Oblong Trees currently provides a noncertified carbon mitigation service for SMEs.
Within weeks of launching Oblong Trees, large corporations started showing an interest, along with many SMEs. “I think there is a need. Businesses want to help but there is little choice out there or in terms of visibility – companies want to see evidence of their spending on the ground.”
A growing number of arborists are also looking to play their part and he advises: “It’s very sensible to plant trees where they’ve been removed. I would recommend planting whips as planting more mature trees costs more and they are less likely to survive the more frequent long dry spells we’ve been having. Also, plant a mixture of native trees where possible and consider rootgrow fungus to help get roots established. It’s best to use biodegradable guards and have someone lined up to water the trees through any dry spell in the first few years.”
He adds that tree planting season is often given as October to March and there has been particular success with trees planted before Christmas, when rootgrow fungus is used, tend to survive better than those planted later in the season.
He is also seeking to raise funds to develop a community woodland. “I’m looking for somewhere, preferably in Warwickshire, to plant a small woodland. The plan would be to take an area of land – perhaps next to a new housing estate or a plot of land HS2 no longer needs. I will plant 60% trees, 20% wildflowers and leave the rest as grass or scrub. I’ll create winding nature trails throughout, installing bird and bat boxes when the trees are big enough, put in hibernaculum, which are underground chambers for
Longer term, Whiteman says he wants “Oblong Trees to grow countrywide, continuing to plant millions of trees, creating biodiverse rich areas of countryside.”
He says he is keeping a close eye on the HS2 project and the track will be within 500 metres of his office. “I can see they’ve taken control of a lot of land that they’ll eventually no longer need, some will go back to farmers and landowners, but I’m hoping to be able to acquire some land and with the backing of UK businesses, rewild it properly. We could create a nature-rich corridor from Birmingham to London.”

Green Plant stocks a range of top quality arboricultural and groundcare machinery that is designed to take any arborist to the next level. Brands that will be of particular appeal to the arb sector and that have pride of place at Green Plant UK’s headquarters in Guildford include Rayco, Norcar, Energreen and Timberwolf.
Green Plant UK is run by Rosemary Brennan and her brother Danny and they, and all the staff, go the extra mile to help customers and provide both products to buy and hire. Full back-up support on all the products is available, and provided by a very knowledgeable and experienced service and parts
Green Plant UK are the official importers for the UK for the Energreen remote controlled tool carriers. The Energreen Robo range – comprising five machines –can be used in a wide range of applications, including bank mowing and forestry mulching, and everything in between those two extremes. Green Plant UK provides a full sales, hire and aftercare service for the machinery.
Energreen is an Italian brand, which is technologically advanced with market-leading features and safety benefits. As Smithers says: “Because they are controlled
team who are always on hand to provide help and advice.
Business development manager, Jeremy Smithers, says: “We’re finding a growing number of arborists are interested in bigger or more capable machinery as their businesses develop and they take on larger jobs. The use of machinery can improve your output with minimal investment."
remotely, these hydrostatic, self-propelled machines are far safer for the operator. The user is removed from any vibration, from a great deal of noise, dust and exhaust emissions, and also off the machine on slopes. At the same time, the operator can choose the best location to observe and monitor progress.
"These are exceptionally well constructed machines, using the Autec remote control system which continuously monitors the working frequency to find the best working frequency and so maintains a stable radio link, even in the case of interference."
Rayco is a leading US manufactured stump grinder, and Smithers comments: “Stump grinding can be a useful extra revenue stream for many arborists or some will choose to specialise in
Force line which are pedestrian stump grinders that can be used in tight spaces and are designed to be taken through a garden gate."

The Rayco tracked stump grinders, such as the RG37T and the RG55T-R are strong compact machines that has the ability to travel where tyres are unsuitable – they offer two speed travel, swing out operator controls for ease of use and a hydraulic backfill blade for stability. The larger RG55T also has remote control functionality for additional operator safety.
The Timberwolf brand needs no introduction and Green Plant UK is the leading dealer of the manufacturer’s wood chippers in the south east. “We have plenty of choice, from models suited to those starting out as well as those looking for larger wood chippers with extra power. We offer competitive pricing and usually have deals available. The expert team will be able to help with all your parts and service needs with their in-depth knowledge of these machines. Parts can be supplied on an overnight service and the workshops are amongst the most knowledgeable in the world of Arb.”
Hiring wood chippers is also a core part of the Green Plant UK proposition for those looking for temporary solutions or just wanting to try before they buy.
These Norcar miniloaders are made in Finland where the brand is well established, now offering a number of options for arborists and associated industries. Smithers explains there is a range of sizes and capabilities with the 755 being the smallest and an ideal choice for an arborist buying their first loader. “The build quality is immediately obvious. The strong steel chassis, the absence of plastics and the oscillating centre joint, which allows all the wheels to follow the terrain is a major benefit on uneven ground. From the driver position in the rear half of the machine, the manoeuvrability is class leading. With a centred, high strength steel lifting boom, these machines are incredibly capable."
Norcar have recently announced the release of two new wheeled Miniloaders: the a7035 with a lifting capability up to 1250kg and a lifting height of over 3.3 metres, and the a7245 which has a more powerful engine and an increased hydraulic oil flow, up to 61 L/min.
The miniloaders have a hydraulic front boom and can be used with a large number of versatile attachments for jobs such as levelling, sweeping and grabbing.
Henchman’s PRO range is aimed at arborists and landscapers and is the established provider’s strongest and most versatile model to date. The range offers two models designed to ensure more adjustability, usability and durability. Being fully adjustable, it offers users many options for repositioning and adjusting when working. Each leg is independently adjustable to accommodate substantial sloping, uneven earth, and steps. This makes jobs in difficult terrains straightforward.
All Henchman ladders feature a built-in platform, however the PRO model has an additional platform below, making it well suited to working at variable heights and offering additional chest support to help users feel more stable.
Numerous design features have been incorporated to increase sturdiness and strength, including more rung supports to add strength in key areas, additional bracing at the first rung, and a thicker gauge of aluminium. There is also a new rear leg
Tom Kitching, Henchman’s CEO, comments: “Our original line up of tripod ladders has been on the market for over a decade and we’ve sold tens of thousands to customers spanning all manner of professional sectors. Over the years, though, we’ve collected feedback, gathered insight and evolved our structural engineering, which has resulted in the new range – an even stronger, more comfortable, and long-lasting ladder that will help our customers get the job done safely.”
catch to hold the back leg securely closed and prevent it from swinging out while carrying, transporting or storing the ladder.
The PRO model comes in sizes: 6ft, 8ft, 10ft, 12ft, 14ft and 16ft and Henchman tripod ladders are the only EN131 certified tripod models available in the UK.
According to Henchman, the ladders provide at least 20% more adjustability than competitors, and up to 80% more on its 8ft models. The new range also features a red or blue-coated third leg and Henchman’s logo plate.
The manufacturer has also introduced a new and improved design for its existing fully adjustable tripod ladder range, which is available in sizes: 5ft, 6ft, 8ft, 10ft and 12ft.
This features three independently adjustable legs for use on any surface, a more generous platform surface for increased comfort, and improved strength and durability throughout, as well as a blue leg.
Henchman launched its first model at the RHS Chelsea Flower Show in 1994. The business was founded by father and son Mike and Tom Kitching and over the past three decades the company has evolved from a small family business to the leading garden ladder brand in the UK. The company is based in Wiltshire and has an in-house design team, which have also created a wheeled Henchman, a hi-
step platform and a range of large capacity wheelbarrows and accessories. Henchman is the only fully EN131 certified tripod ladder on the market in the UK.

When it comes to safety gear, arborists need to be sure that their boots will protect them from the dangerous machinery they regularly work with. However, with the complex safety requirements surrounding necessary PPE, it can be difficult to know what specifications are needed to comply. So, what are the key issues to be aware of as well as some common misconceptions?
While chainsaw protection is undeniably vital, one prevailing misconception is that chainsaw safety boots only need to be chainsaw-proof. However, the evolution of safety footwear has led to an increased emphasis on puncture resistance. Modern chainsaw safety boots integrate advanced technologies, such as composite materials, which provide exceptional puncture resistance. Lightweight flexible steel is also used for strength and protection, including in the HAIX Protector Pro 2.0 and Trekker Mountain 2.0. These enhancements ensure foot protection against sharp objects encountered in hazardous environments, such as thorns, glass shards, or nails.
The construction of uppers in chainsaw safety boots plays a crucial role in offering a harmonious blend of durability, flexibility, and protection. Misconceptions often arise regarding the ideal material for uppers, with some assuming that thicker materials automatically translate to better protection. However, modern chainsaw safety boots use a combination of materials that strike a balance between safety and comfort. This approach ensures boots are both sturdy and flexible, allowing for optimal performance in demanding work environments.
The term ‘waterproof’ can be deceiving, as many boots labelled as such may not provide the level of protection expected. The EN ISO standard, specifically 20345/20347, establishes the minimum European requirement for boots to be classified as waterproof. However, this standard allows of water penetration, meaning water can still enter the boot. Rigorous testing is conducted to evaluate compliance, including the trough test and the Dynamic Water Resistant Test. While the trough test permits
a maximum of 3cm2 of water into the boot, the Dynamic test demands no water ingress. Any boot surpassing this limit fails to meet the standard and cannot be considered truly waterproof. When boots fail to provide sufficient waterproof protection, leading to wet and cold feet, serious health problems can arise. Wet feet aggravate symptoms, weaken the immune system, and impede blood flow to the nose and throat, making the body more susceptible to infections. Maintaining a foot temperature of around 28-30°C and an overall body temperature of 37-37.5°C is crucial for wellbeing and performance.
The GORE-TEX advantage
To combat water penetration effectively, many of HAIX's designed boots incorporate the GORE-TEX Laminate – a waterproof, breathable, and insulated technology. The GORE-TEX Laminate ensures each pore is 20,000 times smaller than a droplet of water, guaranteeing complete and durable waterproofing. By dispelling misconceptions and incorporating cutting-edge features, chainsaw safety boots are now equipped to meet the rigorous demands of forestry work.
The Yorkshire Sculpture Park is near Wakefield in West Yorkshire, and an open-air gallery, showcasing work by artists, including Henry Moore, Barbara Hepworth and Damien Hirst. The park, which opened in 1977, covers 500 acres and surrounds the 18th century Bretton Hall. It has one of the largest open-air collection of Moore’s bronzes in Europe.
This gallery without walls needed remedial work as it prepared to reopen after lockdown. Hydrology consultants checked out the land and found one area was waterlogged.
Greenwich Park covers 74 hectares and is on a hilltop, where views of the Thames and St Paul’s Cathedral can be enjoyed. Millions of visitors come each year and numbers increased massively during the lockdown periods.
“It was like bank holiday every day,” said Adam Stoter, Greenwich Park’s technical officer. “The trouble was, the added footfall compounded the growing problem of compaction in and around the tree areas.”
The Royal Parks’ flagship project ‘Greenwich Park Revealed’ had already begun restoration work to protect and share its heritage and tree care was a major focus – this meant calling in Terrain Aeration’s tree division.
Where there is heavy compaction, it is essential to break up the soil at a depth greater than the tree roots, other than the main tap roots which go straight down. This allows excess water to drain away and help stop anaerobic conditions and rotting of the root system.
The Terrain Aeration Terralift sends a probe to a depth of one metre where compressed air is released to a maximum of 280psi. This fractures the soil and creates fissures which interlink as the Terralift repeats the process on a grid system of two-metre spacings. Dried seaweed is injected which sticks to the fissure walls, expanding and contracting with moisture content in the soil to keep the area breathing. In most cases, the area treated will be one-metre inside and one-metre outside the canopy drip line to reach beyond the growing roots.
Terrain Aeration was appointed to carry out a deep aeration treatment at the area in question, which was an important part of the Lower Park and a popular area for visitors and curators. It had formed by compaction due to footfall and the weight of sculptures, resulting in the build-up of standing water. “It is unusual for the area to be cleared,” said Mark Chesman, head of estates and parks, “but the sculptures in that area were removed for conservation work, and we seized the opportunity as part of a wider project. In all, it took two-and-a-half days and they treated 4,000 square metres of land.”
As at Greenwich, Terrain Aeration’s Terralift hammered a hollow probe one metre into the soil using a JCB road breaker gun and the treatment carried out.
Yorkshire Sculpture Park features lime trees, beech and Atlas cedar among others and these were given the Terrain Aeration treatment too.
Breaking up the soil around the roots, and beyond, meant excess water drained away from the roots to help stop anaerobic conditions and rotting of the root system. “We’re confident with what’s been done,” said Mark, “and will be looking at further areas to be treated, probably in the autumn.”

Aprofessional chainsaw, whether it is cordless or petrol powered, will be subjected to a great deal of stress during use, so it’s vitally important that users maintain a strict maintenance programme to preserve performance and safety levels.
Professional chainsaw operators are aware of the necessary checks to complete before using a chainsaw. These include, but are not limited to:
● A thorough inspection of the housing, cutting attachment, sprocket cover, chain catcher, rear and front hand guard, on/ off switch markings, safety symbols and scabbard. If any of these features are missing, broken or fitted incorrectly, the chainsaw must not be used.
YOUR MOST IMPORTANT WORK TOOL NEEDS PROPER MAINTENANCE – REUBEN WILSON , PRODUCT EXECUTIVE AT STIHL GB , HAS ADVICE ON KEEPING THEM IN GOOD WORKING ORDER
● Testing the lock-out switch to ensure the throttle trigger cannot be engaged until the handle is gripped.
● Checking the control lever can be moved into the ‘off’ position.
● Testing the anti-vibration system to ensure the spring mounts are in good condition.
● Testing the chain brake clicks into the ‘on’ position. The owner’s manual of your chainsaw will specify how the chain brake can be tested safely before operation.
The guide bar wear is highest in the area where most of the cutting takes place, which is the underside of the bar. The bar should consequently be flipped over periodically to ensure even wear.
As the rails wear over time, the bar groove slowly becomes shallower. A minimum groove depth must be maintained in order to prevent the drive links from scraping along the bottom of the groove. If this happens, the drive links wear quickly and the running faces of the teeth and tie straps would no
longer ride smoothly on the rails. The exact measurement depends on the pitch of the guide bar – for example 3/8” pitch bars have a minimum groove depth of 6mm. This can be measured easily by using the scale on your Stihl filing gauge. If the measured depth is less than specified, it’s time to replace the guide bar.
Be aware that pinched or splayed bar rails, as well as bent or twisted bars are difficult to remedy and will usually need to be replaced. In addition, burrs can form on the outside edges of the bar rails as they wear. Burrs can be removed with a flat file or a Stihl guide bar dressing tool. If the left and right bar rails have been worn unevenly due to an incorrectly sharpened chain, they can be levelled providing the difference is not too great. It’s important to ensure the groove depth is checked after the rails have been levelled.
The condition of the spur or rim sprocket should be checked regularly, as a seriously worn sprocket will accelerate the wear to the guide bar and chain. A Stihl reference gauge is available to ensure the wear marks do not exceed the 0.5mm limit. On average, a sprocket can last the lifespan of two saw chains, but this can be reduced if the chain is tensioned too loosely.
● Depth gauges are too low. This increases vibration, kickback risk and the likelihood of chain stress.
● Choosing a chain with humped drive links is an additional way of reducing the risk of kickback occurring. Stihl chains with humped drive links are denoted by a ‘3’ in their name, for example ‘RS3’ (Rapid Super, humped drive links).
The MS Care and Clean Kit is a must for cleaning the intricate parts of a chainsaw, including the air filter, sprocket cover, guide bar and cylinder fins. The kit comes with VarioClean
Eco cleaning spray and a brush with an integrated guide bar groove cleaner. Purchase the MS Care and Clean Kit PLUS for a larger sized VarioClean Eco and the addition of a wash bag that doubles up as a cloth.
Allowing dirt and dust to build up around the cooling fins, filters, sprocket cover and oil caps could lead to components needing replacing much sooner than necessary.
A regular cleaning schedule is essential for the long-term safety and performance of any chainsaw.
arioClean is a spray ideal for use on HD2 air filters, which can be found on all petrol professional STIHL chainsaws. VarioClean can be used alongside warm water, dissolving the chain oil residue, extending the service life of the filter and reducing downtime.
Available for most petrol professional chainsaws, service kits contain the relevant air filter, spark plug and fuel filter for your tool, and are convenient ways of performing routine maintenance. Service kits are easy to keep in the work vehicle for reduced downtime and help to ensure the correct spare parts are used for each model.
aware of the filing aids available for ensuring a sharp, high-performance chain. It’s important, however, to be aware of the two key sharpening errors that not only reduce performance, but also increase the risk of kickback too:
● A hooked side plate angle. This can occur when using a file that’s too small a diameter or is held too low. The hooked tooth causes the chain to snatch in the cut, working less effectively and increasing the likelihood of kickback occurring.
lean brush will also come in handy for removing saw dust from the electrical contacts on cordless models, for ensuring the cooling fins and flywheel are free from obstruction and for removing dirt from under the sprocket cover. Stihl’s Multispray can be used alongside a damp cloth to loosen stubborn dirt that cannot be removed by brushing alone.
● Pay close attention to dirt around the oil and fuel caps, as this can fall into the tank when the cap is removed and reduce the service life of the filters.
Maintaining a chainsaw is a must for professional users that are hoping to get the best out of their machine and keep it in
Rapid Hexa consists of a patented hexagonal file and a full chisel chain with a unique V shaped side plate. These unique features result in a chain that is much easier to sharpen compared to conventional chain. Thanks to the narrow kerf top plate and 25° top plate angle, a Rapid Hexa chain is well suited to diagonal felling cuts on a variety of wood types.
safe condition. This is not a comprehensive list of all the necessary maintenance tasks – this can always be found in the owner’s manual of your chainsaw. If in doubt, contact a Stihl dealer for more tips and guidance on cleaning and maintenance.
Key features
• The saw head moves up/down and forward/reverse electrically. Water from the tank feeds lubrication directly to the blade to improve cutting. The electric blade guide arm keeps the blade supported while cutting various-sized materials. Blade tension is easily adjusted and keeps the blade at the proper tension for cutting. An optional debarker keeps the sawmill blade sharp for longer as it clears dirt and rocks from the bark.
Choice of motor
• Options are the 7.5kW, 11kW, and 15kW electric motors, the 25HP petrol engine, and the 22HP or 25HP diesel engines.

GreenMech launched a new entry range at this year’s Arb Show. The ECO 135 delivers 5” capacity and is well suited for a wide variety of applications and operators, particularly those who may be starting out and who are more price-conscious.
Initially, there are two models available – the ECO 135 road tow and the ECO 135TT as a full 360o turntable road tow. According to GreenMech, the models are designed to be cost-effective and easy to run and maintain, without any compromise in strength and performance. The range retains many of GreenMech’s features, such as horizontal rollers, nostress feed system and twin disc-blade chipping technology, combined with a new flywheel design which provides good throughput for a machine of its size.
Power is delivered by a powerful, yet economical, 24hp Loncin petrol engine and both models can be up-specced to suit applications and budgets. Options include a variable height discharge chute, spare wheel, stowage box and the GreenMech HushChip pack, which provides additional component protection and reduces noise output. LED lighting can also be specified to replace the filament kit fitted as standard.
“Even in the basic specification, the ECO 135 range offers brilliant performance combined with excellent value for money,” says sales director Martin Lucas. “Both models weigh
less than 750kg and include many of the popular features which have now become synonymous with delivering outstanding reliability and safety. The fact that we can also deliver a turntable model is a real bonus, particularly for those customers who require maximum flexibility in positioning the machine for safe operation.”
Models come with a three-year GreenMech warranty and the back-up service and support from the nationwide dealer network.

This newly launched model builds on the legacy created by the 750KG ST6P wheeled wood chipper.
The ST6P HD is a heavy-duty wood chipper that brings the performance and speed of the ST6P. It features a heavy duty steel bonnet and chassis, beefed up running gear and jockey wheel and there is a spare wheel attached to the machine.
It also offers the FörstGrip feed roller system, the Först flywheel system and the new and improved AutoIntelligence control and ‘nostress’ system, which provides fast and efficient chipping performance. It is fitted with the fuel-efficient Vanguard 37HP V-Twin petrol engine as used in the ST6P.
Douglas Ghinn, commercial director, comments: “We launched the ST6P as a big, beefier brother
to our best-selling ST6P. The HD came about due to the relaxation of towing laws, and it actually enabled us to make the machine we’d always wanted, without having to compromise. It’s got a heavyduty steel construction and still only weighs 885kg. It’s based on the ST6P so customers are still getting the same high performance chipping but the heavy duty nature of this wood chipper makes it much more robust and better at withstanding the hard life of arb machinery.
“This is an important machine in the Först line up and we’re now seeing more people look to trade in their ST6P for the heavy duty machine as their machines reach the threeyear-old point.”

The TW 280HB Hybrid was developed to meet the growing industry trend towards more sustainable solutions. It has processing throughput of over seven tonnes/hr and class-leading peak power of 62hp. The model is designed to be simple to maintain and is ideal for those who are committed to minimising their emissions without compromising on performance.
Timberwolf conducted extensive research of hybrid powertrains and following discussions with engine manufacturers, concluded that no commercially available solution was currently available. The manufacturer then led its own hybrid powertrain development programme to meet the dual challenge of addressing performance and emissions.
The Timberwolf engineering team placed the 24.8hp (18.5kW) Kubota D902-TE4 turbo diesel engine at the heart of their hybrid design. This Super Mini Series powerhouse was chosen not only for its pedigree, but also its high RPM and outstanding applied torque.
Supplementing engine generated power is a power-dense hybrid system. Integral to this system is an Inmotion Generator Synchronous Motor (GSM) and energy efficient SECH supercapacitors. This provides swift recharge capability and in contrast to Li-ion battery solutions, supercapacitors store and release the energy quickly, coping with the variable duty cycle of the arborist’s tasks at work.
This is integrated in a self-supported system that does not need external charging to operate. As the arborist’s working environment is always variable and the work schedule often long, the TW 280HB HYBRID will perform throughout the day.
According to Timberwolf, this model exceeds the objectives set out by the business and target stakeholders; to provide class leading 62hp peak power but with emissions at the level of a Kubota 24.8hp engine.
It requires only a small number of simple daily checks and regular
greasing required to keep this machine operating at peak performance. Additional features to assist operators also include enhanced operator diagnostics for easy troubleshooting and it comes with a three-year warranty as standard.
“Taking existing technologies to develop an industry-first solution has been a very exciting innovation and development project,” says Chris Perry, who serves as Timberwolf’s managing director. “The team has excelled in identifying and delivering an outstanding technical solution to meet this increasingly important market need.
"For over 35 years, the Timberwolf brand has been synonymous with wood chippers and now, as we launch the TW 280HB HYBRID, we demonstrate our commitment to use the strength of our technical expertise to meet the sustainability challenges of the future.”

Vermeer is currently celebrating its 75th anniversary since its formation on a farm in Iowa by Gary Vermeer in 1948. His Great-Grandfather emigrated from the Netherlands to Iowa in 1852. He was a farmer with great talents in mechanical engineering, redesigning farm vehicles before Vermeer invented the stump grinder in 1952. Vermeer Manufacturing now produces a large range of machinery for the arboriculture sector.
Vermeer fully owns its UK distribution business and Paul Doyle in sales says business is brisk. “We’re one of the
leading brands and preferred by many local authorities. We’re strong in the arb sector – we probably won’t be first choice when someone is starting out, but if their business is thriving three to five years down the line, then we are likely to be the brand they turn to. Feedback regarding the BC1000XL suggests it is one of the best chippers on the market that can take on the bigger jobs. It is also good news that arborists now also appear to have the exemption back to use red diesel, which allows for welcome fuel savings.”
Vermeer also manufactures stump grinders and skid steer loaders. “Many of our
All models feature the Eco-Idle engine control system, which is trademarked to Vermeer. This reduces fuel consumption if the feeding process has frequent interruptions and also results in reduced noise on site.
arborist customers have found they are so impressed with the chipper, they will also buy a stump grinder; a growing number are also investing in a mini loader.”
A further benefit is that pricing is also now more competitive. “It’s all connected to sterling and the dollar – lately, that’s meant that our UK prices are now a lot more affordable than you may think and we also have financing options – you may be pleasantly surprised that a Vermeer is well within reach.”

BC200 Brush Chipper
The most compact of the range at just 1,465kg, the BC200 operates with high efficiency as well as leading safety standards. Panels are fabricated to provide easy access for maintenance work. Fitted with a Stage V compliant petrol 57 hp engine from Kubota, it features a letterbox-style 8”x12” opening to allow rapid feeding of material with side branches The BC200 is available with a turntable on a double-axle.
BC230XL Brush Chipper This is the mid-range chipper, which now has a 74hp turbocharged Caterpillar engine and a wide 9” X 14” infeed opening. It also features twin horizontal feed rollers with the offset lower roller to allowing large short lengths to be fed without kick-up. The SmartFeed system pulls in and processes challenging material, while the 180-degree rotating upper structure improves safety when working at the roadside.
BC1000XL This is the heavy-duty Vermeer –although all in the range are extremely robust. Fit for the biggest jobs, it has an all-steel engine enclosure and is fitted with a CAT C2.2 Tier V 74-hp diesel engine that meets all the latest emission regulations. Rubber torsion suspension ensures smooth towing and it also offers Smart Feed with Auto Reverse. Once the shield is opened, users can easily adjust and change belts, and the clutchless PTO system eliminates the need to slide the engine.
Makita has expanded its range of 18V LXT cordless maintenance machines with a number of new launches, including a blower, hedge trimmers and rear handle chainsaw.

The DUB187 Brushless LXT Blower features both blower and vacuum functions and has a variable speed trigger control along with cruise control for ease of operation.
In blower mode, the DUB187 produces a maximum air volume of 4.2 m3/min with an air velocity of up to 64m/sec. As a vacuum to pick up leaves and garden debris, the model has a maximum air volume of 6.1m3/ min. It benefits from a 25 litre collection bag and features a metal shredder blade on the fan for mulching. For comfortable use, there are top and rear handles as well as a shoulder strap and two casters on the blower/vacuum nozzle for ease of movement.
Hedge your bets
Makita has also launched four new hedge trimmers. The DUH507 and DUH607 LXT hedge trimmers have 500mm and 600mm blade lengths respectively and the machines deliver an output of 250 watts, a blade speed of 2,700 strokes per minute with a 15mm maximum cutting capacity.
The DUH506 and DUH606 Brushless LXT hedge trimmers similarly have 500mm and 600mm blade lengths. These machines have an output of 320 watts with a blade speed of 4,000 strokes per minute and a 20mm maximum cutting capacity. The brushless motors on these models deliver improved performance and runtimes compared with equivalent machines with conventional brushed motors.
The hedge trimmers are lightweight and include an aluminium guide bar, to reduce user fatigue as well as a redesigned front switch for easier operation. They also all have optional chip receivers, and safety features such an electric brake, while the DUH506 and DUH606 feature an anti-restart function.
To help professionals achieve maximum productivity, the DUB187 blower and the new hedge trimmers are all compatible with the Makita PDC01 portable power supply. This backpack battery unit can be fitted with up to four LXT batteries to provide extended run times for a wide range of Makita 18V and Twin 18V (36V) LXT machines via a connection adaptor.

Are you thinking of turning to tree surveys? It’s not uncommon for arborists to focus on providing surveys once climbing becomes a stretch too far. Those who make the switch tend to have few regrets if they can obtain the necessary qualifications –they can still work outdoors and there is much demand for this highly satisfying work.
There is plenty of training available and this ranges from introductory one day courses from Lantra all the way up to degree level. Meanwhile, should you be planning to set up a tree surveying service, there is a need to invest in quality equipment. Advice on the core components will often be provided by the training provider. It is also necessary to link up with specialist suppliers that have a strong selection combined with quick delivery and competitive pricing.
TreeMarker was set up in 2019 and director Peter Greenley says there has been steady growth. He adds that a number of his regular customers are arborists who are now offering tree surveys. “We are willing to supply small orders – such as 100 tree tags –and also ensure that the products on our website are in stock. It’s frustrating to find you might have to wait a few weeks for a product to be delivered, so I was determined we would provide fast dispatch and put

The work of a tree consultant can be complex and demanding, but the team at Tree Diagnostics has the ability to make it appear logical and straightforward.
The company is run by Ian Barnes and it is a division of Barnes Associates – fellow director is Ian’s wife, Sue. She is a lead landscape consultant as well as being a specialist in tree care. Along with Ian, she works with a wide range of clients in the public and private sectors. There are also four consultants, with the whole team being highly qualified, and all having continued to study throughout their careers as well as having hands-on experience with horticulture or as arborists.
Ian initially planned to work in horticulture, having studied at Askham Bryan College in York. However, he realised, when taking the arboriculture module, that he wanted to work with trees. “I’d had experience of commercial horticulture but knew trees were what really interested me. I was also a natural at climbing. Being paid for doing it was even better.”
Ian then built a career as an arborist, employing staff and running a fleet of vans and wood chippers. But he was also increasingly providing consultancy services and so decided to focus on this full time.
“I didn’t want any conflicts of interest and also found there was growing demand for surveys and independent advice.
I also found I enjoyed study and have ended up taking a BSc in arboriculture at
Myerscough College.” Ian is also a registered consultant with the Arboricultural Association.
He explains that many arborists can underachieve at school and dyslexia can be commonplace. But, once someone finds an area they really enjoy, a spark is ignited and
Working as a consultant can involve using sophisticated equipment and Tree Diagnostics is the UK distributor for Fakopp – a world-leading Hungarian specialist. “The kit means you can test in a non-destructive way; we try to avoid drilling or boring so that there is no damage. We supply a wide range of customers, including consultants, local authorities and universities, and provide training on using the equipment.”
Types of equipment from Tree Diagnostics
Equipment is often used along with specialist software and can be based on tomography which uses sound waves to detect decay in trees, such as the Arborsonic 3D which allows tree decay to be scanned and provide a tree safety factor calculated using the software. The range includes:
advanced learning is possible. “I write many long reports now with ease, but would have found this much harder when I was younger.”
What is more, he believes surveys and dealing with the more difficult problems concerning trees can be a “natural progression” for arborists and they will be able to work and study to become consultants if they wish, and Ian says he and his team are able to provide guidance.
“It’s a role where you need to be independent – there can be a misconception that we are about saving trees at any cost. That’s not the reality, although we can show –using advanced equipment – that a tree may not be a hazard. There’s increasing awareness of the value of trees and the old adage of ‘when in doubt, take it out’ no longer applies. More people want to retain trees if they are safe and they add so much to quality of life.”

The kit means you can test in a non-destructive way
The UK needs to plant more trees if the country is to meet its net zero goal by 2050 and in particular, there is demand for more workers who are skilled in the craft of forestry.
They will help progress the government’s accelerated programme, which is to plant trees that will absorb carbon emissions – the UK has a target of 30,000 hectares of new woodland being created every year by 2025.
Currently, the industry employs around 10,000 people in forestry, but this is some 7,000 short if it is to hit the government’s target and last year, for example, the figure was only 13,850 hectares.
A recent BBC report claimed that those with a passion for the environment and who are prepared to work hard are “guaranteed jobs”. So, what are these roles and how can they be accessed?
At the top of the tree are jobs for those with forestry degrees and one project, currently underway at Bangor University in Gwynedd, aims to dispel myths about the sector and show it is welcoming new entrants – it is also seeking to attract a more diverse workforce.
Students at the university have set up the Inspiring Future Foresters group, and are using social media and school visits to promote the sector. “Anyone who hears about forestry thinks it’s just about big men with chainsaws cutting down trees,” said
Master’s student Mercy Babatunji, who said there were many career opportunities.
The 25-year-old from Nigeria hopes to work as an urban forester after finishing her studies, promoting and managing trees in towns and cities.
Katie Somerville-Hall, 24, from Reading, said students on the course were told: “Everyone just walks into a job afterwards”.
Bangor is one of only three universities across the UK training foresters to degree level and according to Dr Tim Pagella, who runs the undergraduate forestry programme: “We anticipate that there are currently around 500
unfilled professional positions in the UK and probably a further 10,000 support positions.” The sector is under further pressure as by 2030, some 20% of current foresters will have retired.
Leaving a job to study, particularly later in life, can be exceptionally difficult because of the cost. However, the Forest Industry Safety Accord (FISA) has launched a new bursary to support students on professional forestry degree courses. Director Sean Reilly said the industry was often not regarded as
THE TIMBER SECTOR HAS PLENTY OF OVERLAP WITH ARBORICULTURE AND FOR THOSE LOOKING TO ESCAPE THE URBAN SPRAWL, FORESTRY CURRENTLY OFFERS A RANGE OF OPPORTUNITIES
could be the career for
a “professional” career choice and this needed to change. He pointed out that forestry was more highly regarded in Europe. Meanwhile, the UK government is spending some £4.9 million on projects to support forestry education and skills under the Nature for Climate Fund. This includes a new professional forester apprenticeship programme at the University of Cumbria, the first degree-level forestry apprenticeship that has been offered in the UK.
Rob Hawkins, senior education and outreach officer for the Institute of Chartered Foresters, commented: “There needs to be a campaign to raise awareness of the breadth of careers available in forestry. It offers highly skilled, technical, green jobs, far removed from the old lumberjack stereotype that sadly still persists.”
Apprenticeships are increasingly popular and forestry is also now available. The Forestry Commission is now running annual apprenticeship programmes, with the next to begin in September 2024. The scheme is run in conjunction with the University of Cumbria and the Institute of Chartered Foresters.
Details are available at: gov.uk/guidance/ apply-for-a-forestry-apprenticeship.
Around 15 trainees participate in study and events over three years such as visits to the APF expo and a visit to the Lake District to study silviculture.
Although run in conjunction with a university, there are no exams – although it is considered a degree-level course. Instead, students are marked on continual assessment and are required to submit regular assignments. The course is 20% academic study and 80% on the job training. One key benefit is that this will suit those who are looking to switch from other jobs since it is a paid role, paying £23,098 per year and on successful completion, a Level 6 Apprenticeship in Professional Forestry, BSc (Hons) Professional Forester is achieved. In Scotland, the government takes on even more apprentices – 25 in total – who are based in departments throughout the country. They work out in forests, along with study of data science, engineering and procurement. Details are available at: forestryandland.gov. scot/jobs/apprenticeships.
Scotland in particular is in need of more forestry workers. The country is home to seven out of 10 of the UK’s largest forests but, even so, there remains too little interest among school leavers and the Scottish School of Forestry in Inverness has currently paused its full-time BSc course because there were too few applications. Efforts are being made to reach more students through the tutors at the university connecting with schools and the longer-term aim is to embed forestry education into the curriculum.
There are a range of forestry courses available through further education colleges and some have been made available free of charge, by the Department for Environment Food & Rural Affairs and the Forestry Commission. These are currently all allocated for 2023, but may be made available again for 2024. Courses are funded by the government via the Forestry Training Fund – and teach skills including coppicing, chainsaw maintenance and crosscutting, managing woodland, planning and planting new woodland, marketing and selling timber and fence and hedge laying. Those who want to participate, should keep an eye on the Forestry Commission website to see when the fund will start allocating again –gov.uk/government/organisations/ forestry-commission.
To simply get a taste for what working in forestry is like, then head to the Confor website which provides insight into some of the varied jobs on offer based on real life case studies – confor.org.uk/our-story/a-careerin-forestry/.
Confor is also supporting former military veterans who want to work in forestry and connect those wanting to find out more with former services personnel who have already made the transition. There are also more case studies about working in the sector at the Forestry England website at: forestryengland.uk/careers.
The demand for forestry workers is only set to increase and for those looking for a change of scene, then this sector could well be worth some serious exploration.
There needs to be a campaign to raise awareness of the breadth of careers available in forestry. It offers highly skilled, technical, green jobs
AS THEFTS INCREASE, A TRACKER CAN PROVIDE ONGOING PROTECTION FOR YOUR WOOD CHIPPER OR SKID STEER LOADER – IN FACT, THESE DEVICES SHOULD NOW BE SEEN AS ESSENTIAL KIT
Any arborist buying either a new or used wood chipper or skid steer loader needs to think about how to protect it. Theft of valuable kit is commonplace, it occurs throughout the UK and the impact is often devastating since the loss of a high value and essential work tool makes it impossible to earn an income.
A tracker may also be required to take out insurance and arborists should make sure they fully understand the terms and conditions around this. For example, if they install a tracker but fail to keep the subscription up to date, there could be issues with making a claim.
At the same time, a tracker, although usually highly effective, can never provide a total solution. It is possible a thief may be able to locate and disable it, but there is still far more chance of a recovery with a tracker than without. Experts on security also advise that a range of measures should be employed. You may also choose
to back up the tracker with a chain and a wheel lock, in addition to keeping the chipper or skid steer in secure premises,
a crime reference number so they can make an insurance claim but there can be little in the way of investigation.
There are a range of trackers available and arborists should check out which is best suited to their particular needs. Gary Cary, sales agent with TruTrak, says the benefits of his tracker is that it is selfinstalled and simply needs a power source such as a 12V battery to operate.
ideally with CCTV installed. It may seem like a lot of expense but those who have had their kit stolen will know to their cost what their consequences can be.
Insurance companies may take many weeks to check details and hold back on payment until they are satisfied the claim is legitimate. Further, some arborists report they have received little support from the police when kit is stolen. They may receive
TruTrak is one of the main brands arborists use and has won a number of awards – it provides trackers for individuals, small and large fleets.
Cary says the company has developed its own cloud-based solution with apps for Android and iPhone, allowing the provider to customise the platform based on customer feedback or adapt to individual customer requests. He explains: “We aim to be affordable and each client has their own account manager with access to dedicated support.”
We can share real-time location with the police with accuracy down to three to five meters
There is no binding agreement and this allows the tracker to be taken out on a pay as you go basis as required. He adds there are also a series YouTube videos showing how the trackers work. But, should arborists put a sticker on their wood chipper or skid steer to say it has a tracker? There is an argument to say that thieves may attempt to find and disable it. Cary says this does need consideration, but there is also an argument to say that it will act as a deterrent and criminals will have second thoughts about attempting to take it.
a hard time but “in their defence, most of the time, what can they do? They no longer have the resource they had and certainly no time to
Bill Taylor, sales and marketing director for ATVTrac, says the tracker would be fitted by one of their approved dealers. The owner would then set up a secure account via the website and can also download an app to see their machine in real-time. This allows them to see the battery level of the machine and if it drops, they will get an alert. Further, if the machine is moved without being disarmed for more than 20 seconds, the owner will get a phone call, text and email. If a false alarm is raised, the alert is closed down.
“If theft is confirmed we ask the owner to call 999 to get a crime number, call our SOC (Secure Operating Centre) and we pick up and do the rest. We can share realtime location with the police with accuracy down to three to five metres. If the machine is hidden, for example in a container, van, garage, we can use radio frequency to locate that down to one metre. In the rare event the police cannot attend in good time, we have a partnership with Securitas who have staff nationwide who can attend on our behalf. On average our recovery time is within two hours of when theft is confirmed.”
There is no doubt that there is now more pressure on owners to protect their kit. As Taylor points out, the police can be given
investigate like they used to. With a tracking device, it gives them something to work with in real-time. When our SOC calls and we ask for support, they know that we can see the machine’s location and generally, in a short matter of time, they can recover the asset and move on to the next crime – unless we can catch the thieves red handed which then is a better result.”
He agrees that arborists should “layer up” on security where they can. “In addition, marking systems are useful as this helps the police identify assets. If left on a trailer, lock the trailer with a wheel clamp and if you can cover the asset. If the thief cannot see what it is easily, they will keep going, but a bright orange or green machine will catch the eye of a thief.”
On average our recovery time is within two hours of when theft is confirmed

Connick Tree Care works with a range of customers including businesses and homeowners, offering tree care services such as pruning, felling, planting, stump grinding and consultancy. It covers a wide area within the South East, including Surrey, Kent, Berkshire, Sussex, Hampshire and London and employs around 75 people.
In 2022, owner and managing director Mike Connick decided the business he set up some 38 years ago should become employee owned. This was achieved through an Employee Ownership Trust (EOT) – a majority of the company shares are held in a trust for the benefit of current and future staff.
An EOT means employees become joint owners of the business in which they work. At the time of the transition, Connick said: “I want to make sure that the business stays in the hands of the team who helped build it Moving to an Employee Ownership Trust is an opportunity to make sure the caring ethos we’ve fostered can continue, with our employees themselves at the helm.”
No changes were made to the management team and all employees are beneficiaries and eligible to share in the trust’s profits. Broadly, EOTs tend to experience more growth, with motivated employees empowered to drive their businesses forward.
Connick saw the move to an EOT as a logical step. “I’ve been managing director since the start, but without a doubt, it’s the team who’ve built our organisation.
It’s their hard work which has allowed us to remain successful over the years and adapt to changing market conditions and business needs.”
Staff are represented by an employee council which allows people to have their say on how the business is run and as Scott Cain, Connick team leader, and employee representative, said: “Now we know that the harder we work, the greater the opportunity for financial benefit for all staff. It makes me feel proud.”
The success of the new structure was also a contributing factor in Connick Tree Care’s success in the Pro Landscaper Business Awards. The company was named Arboriculture Company of the Year for its high standards in areas like staff training, health and safety and positive customer feedback.
Connick Tree Care is also an Arboricultural Association approved contractor, which is the only comprehensive accreditation for arborists in the UK. The company is also looking to become more diverse and to ensure as many of its arborists as possible achieve the Professional Tree (PTI) Inspector qualification.
It asks all staff to sign a customer service pledge, to ensure best practice.
Connick is now looking forward to retirement and he says the EOT structure has worked exceptionally well. He comments: “It’s a great process and a win-win situation. It's good for me but also for the employees, who have got no financial outlay and yet they’re the owners of a company who share in the profits and in the way it’s run.”
He is now gradually stepping back from the business and reducing the days he works, eventually stopping altogether, but remaining involved with the board of trustees. “I’ve got a very good leadership team and they are taking on more responsibility. As I reduce my responsibility, there’s plenty of energy, enthusiasm and ability to take on more.”
Connick Tree Care is also using its EOT as a way to encourage new joiners. The company recently promoted this in a recently commissioned video – A Great Place to Work – as part of a recruitment drive for climbing arborists. Knowing the business is in their hands is a powerful message and the business is also showing this in its tagline of “We own, we care.”

Now we know that the harder we work, the greater the opportunity for financial benefit for all staff. It makes me feel proud
Afootpath in Swanage, Dorset that was likened to ‘a jungle’ was cleared by an arborist after the local authority proved slow to act. Jamie Rudge runs JSR Tree Care & Garden Maintenance and lives near the footpath along Burlington Road, which was severely overgrown, largely from epicormic shoots from lime trees.
The location is a popular area for retired people and many were finding they were having to battle their way through the vegetation. This meant walking in the road as the pavement was so badly affected and residents said they needed to do this “to avoid a face full of leaves and insects”. A number of local people were infirm, while mothers pushing buggies were also unable to walk along the pavement.
residents, but since many are elderly, they could not do the work themselves. So many were just using the road and there was a risk they could have been hit by a car. I didn’t want this on my conscience when I could do something about it and the work only took me about half an hour.”
After completing the work, he removed the trimmings and took them to the local commercial waste disposal area. The local residents were delighted to have their footpath back and took to social media to say thank you, including the message “not all heroes wear capes.”
So, aware that the local population was feeling increasingly inconvenienced, Rudge stepped up to put matters right. He firstly checked with the local authority to ensure none of the trees were subject to TPOs and then set to work with his Stihl and strimmer. He comments:
“I knew the footpath was causing annoyance to a lot of the
One post also suggested that Rudge “should invoice Dorset Council”. This will not be happening though and a spokesperson for the local authority said: “We manage over 200,000 trees in the Dorset Council area, of which around 50,000 are limes that have all been growing excessively recently.
“As soon as we were made aware of the situation at Burlington Road, we visited the area and felled one tree that was an immediate danger. Our small team, who are dealing with the issues as quickly as possible around the county, will return to Burlington Road to cut back and remove branches.” So far, no comment has been received now that the work is completed.
Jamie’s actions have resulted in positive local publicity, which is all good news for the 30-year-old. He set the business up seven years ago and is originally from Berkshire, before studying at Merrist Wood College. Later
he moved to Dorset and studied more advanced arboriculture work with Terry Banyard, an NPTC assessor and trainer from Bournemouth.
He now works as an arborist for a range of clients, along with three employees and there are plans to take on an apprentice. He provides tree care services for local residents along with holiday homes and grounds maintenance work.
He can now expect to be even busier as the good deed also resulted in new clients coming forward. “I wasn’t expecting it, but had around 25 people get in touch to see if I could do work for them – they’d all read about the footpath work from the local press.”
ARBORIST JAMIE RUDGE TOOK IT INTO HIS OWN HANDS TO CLEAR A POPULAR BUT SERIOUSLY OVERGROWN FOOTPATH – MUCH TO THE RELIEF OF THE LOCALS

What does your role involve?
Along with the normal administration work needed to run a sales and marketing team, and working with two regional sales managers, I oversee the distribution channel in the UK and work directly with some key accounts.
Beyond the UK, we have sales and warehouse facilities in both France and Germany, which look after their own territories. The distribution of products in the rest of the world is my responsibility.
How long have you worked for GreenMech and what did you do previously?
I joined GreenMech in August 2007, so coming up to 16 years now. Before that, I was the business development manager for Club Car, the golf and utility cart manufacturer, covering the UK and Ireland.
What GreenMech chippers are selling particularly well at present?
Without a doubt, the EVO range is our most popular product. Since we launched the EVO product in 2019, we’ve pulled back a lot of customers from one or more of the ‘orange’ brands.
How have you developed your knowledge of trees and tree work?
The old saying “you learn something new every day” is never truer. Beyond the normal tree work around the farm and helping out as a groundie in my youth, I had very little knowledge of trees and tree work when I entered my role at GreenMech. However, by talking and listening to customers at trade shows and on demonstrations, I‘ve learnt that one model does not fit all and that, as you travel around the world, you learn that a job done in the UK is tackled differently somewhere else.
When does an arborist need to upgrade and what benefits can it bring to their business?
Do enough know about jobs in the tree sector?
Like many industries, there’s a lack of awareness around the opportunities of working with trees. It’s a global issue and one that comes up in regular conversations with concerns about how to get the next generation interested in the sector. Perhaps as robotics and automation get a grip on the industry, we might see a change…
How would you describe yourself in three words?
Enthusiastic. Responsible. Collaborative.
You’re known for your sales ability –is there one tip you could pass on?
Always be straight with your customer and don’t try selling too hard. It’s the advice given that often wins the day.
It goes without saying that machinery is one of the biggest investments an arborist has to make and it’s therefore important not to keep the units too long, resulting in a low secondhand value. Many arborists today look for finance to purchase their equipment and, to make it affordable, will stretch the payment term to three, four or five years. I feel that at five years, there’s still a good value to the machine, which makes it affordable to part exchange against a new machine, thus helping you keep pace with the latest technology.
Do you enjoy meeting arborists face to face and how useful are events such as APF and the Arb Show?
Yes! It’s always good to get together with like-minded folk and these are great events to be at and certainly ones we at Greenmech look forward to, especially the APF as it’s only a couple of miles away from the factory.
How do you like to switch off when out of work?
I’m very fortunate to live in the countryside and, perhaps I’m an oddity, but I do enjoy cutting the grass and hedges.
