WELCOME

elcome to the May issue of Pro Arb. It's another superb issue hitting your desks this month, not least because of our interview with the vice chair of the London ree O cers ssociation, ohn ar er. ohn is well placed to spea on behal o tree o cers around the UK, and he touches upon the ongoing funding cuts that threaten the safety of our trees, and how the re erendum could a ect imports. Our Agenda this issue tackles a similar topic: how should we deal with diseases imported from urope ll said and done, the high proﬁle ash dieback is just one of many diseases that could spread through the population and a ect arborists around the country. Speaking of Europe, I was taken to Germany and Switzerland this month for a tour of STIHL GB's factories. STIHL is celebrating its 90th anniversary and it seems incredible that one of the biggest brands in our market has mostly developed organically – only two of its ranges were purchased elsewhere. Another company celebrating its birthday this year is Timberwolf, which is turning 30. I spoke to owner Richard Marshall about how a family

business evolved to what is widely regarded as one of the best British manufacturers in our industry. If you think you’re ambitious, read this article – you may change your mind. Elsewhere, we've got the second part of onathan a ell s series on tree surve s on page 15, and Bartlett Tree Experts warns against the emerald ash borer and o ers preventative measures on page 16. That’s it for this month. As ever, if you have a comment about this issue, please do get in contact. I’d love to hear from you. Have a great month.

AGENDA

AGENDA PRO ARB ASKS INDUSTRY INSIDERS

“HOW DO YOU THINK THE UK SHOULD TACKLE DISEASES IMPORTED FROM EUROPE?” JON BANKS AND EMMA SCHAFFERT Bartlett Tree Experts

“Plants imported into the UK should undergo a period of quarantine” Biosecurity measures are highly important for protecting our tree population. Plants imported into the UK should undergo a period of quarantine, especially those with known pest and disease issues. Particularly with diseases, symptoms may not be visible at certain times of the year or in the early stages of infection, so monitoring trees over at least one growing season is recommended. Allowing emergency pesticide licensing for newly imported pathogens should also be very high up on the agenda for those involved in pesticide licensing and policy. Improving pest and disease knowledge is an undervalued means of containing outbrea s, as rapid identiﬁcation and intervention are key. Simply speaking to your tree suppliers, colleagues and the public can ma e a huge di erence in reducing the spread of a new disease from Europe. It only takes one infected tree to threaten future tree health in the UK, like with diseases such as Xylella fastidiosa and Ceratocystis platani.

Agenda.indd 4

ED HAUNTON

Founder, EH Treecare Ltd “We need a uniform way of logging information onto a database” One of the biggest problems that needs addressing is communication. If there was a uniform way of logging information onto a database using a generic system, that included details on vulnerable trees and signs to look out for, we would have a greater chance of tracking and lesser chance of losing the initial data analysis.

TRACY CLARKE

Director, Tim Moya Associates “The real answer is in diversifying the urban tree population” Our view here at TMA is that although controlling the spread of disease is important and vigilance in this respect should be continued, the real answer is in diversifying the urban tree population to make it more resilient in the face of threats. The Forestry Commission has stated: “We want to ensure London’s trees are best placed to cope

with future challenges by building a diverse, healthy tree and woodland landscape.” We agree with this approach. Although biosecurity is important, the survival of a healthy urban tree population will ultimately depend upon its diversity and resilience.

KEITH SACRE

Arboricultural and urban forestry director, Barcham Trees Plc “Trees should not be bought directly from abroad and planted out” Every landscaper, contractor and professional has a responsibility when it comes to planting trees in the UK environment. As a minimum, imported trees should only be planted in the UK landscape if they have been held on a UK nursery for at least one growing season and subjected to a full pest and disease control programme, coupled with DEFRA inspection. It should be a requirement of any tree purchase that the supplying nursery be able to state when the trees came into the country, how long they have been held at the nursery and supply a full audit trail both into the nursery and out into the landscape. Trees should

05/05/2016 11:25

not be bought directly from abroad and then planted out into the UK. It is the responsibility of everyone planting trees to ask these questions and ensure that the stock they use meets these criteria.

STEVE MCCURDY Managing director, Majestic Trees

“Individuals can import directly with no inspection of their plants” More pests and diseases have entered the UK in the past 10 years than the previous 100. Xylella is a massive problem and my greatest concern is the current EU legislation approach to import laws, which mean groups such as the ABC Landscape Company, Alison’s Garden Design or Mrs Brown, a private individual, can import directly with no inspection of their potentially infected plants. This happened with Chalara, and under this legislation, one can import infected trees to within 10km of Majestic Trees, incur a demarcation zone and put our company out of business. Surely it is only fair to ban all imports of plant material by anyone, unless they can meet the inspection and quarantine rules of this legislation?

CHRIS MILLS

MARK CHESTER

“A system is needed with information about the health of all UK trees”

“One approach is to monitor trees and shrubs in situ”

Human activities such as trade, transport and tourism are key entry routes for invasive species, making it vital to step up biosecurity. However, it’s unrealistic to expect all threats to be stopped at the border, so a system needs to be put in place which provides detailed information about the health of all UK trees. This could be used to monitor and predict potential risks. When planting new trees, it’s the individual’s responsibility to ensure quality stock is sourced from a nursery which operates tight biosecurity measures. Recent developments in plant health legislation mean that certain species now require a plant passport. There are also simple biosecurity measures everyone can adhere to, such as keeping boots and vehicles clean and reporting any signs of ill health.

What we need to do is stop unrestricted imports. The challenge we have is that it’s a free market and with the current constraints, we’re very limited. The existing policies seem to be ‘wait until the horse has bolted before we close the stable door’. Those charged with managing the nation’s plant health seem to do nothing until a disease has become established. One approach to the matter is to monitor the condition of trees and shrubs in situ – this has been proposed using smart tags which can provide a record of stock wherever it is. Whether the nursery sector is willing to resource and embrace biodiversity remains to be explored. It still seems easier to import plants when we need them, and not hold them on site for monitoring prior to planting.

NEW ‘VISION’ FOR ENGLAND’S URBAN FOREST England’s National Forestry Forum has been challenged to play its part in growing the importance and size of England’s urban forest, following the publication of the Forestry Commission’s ‘Our Vision for a Resilient Urban Forest’. The vision is a call to action for a resilient urban forest and was produced by a network of urban forestry specialists from the Forestry Commission’s Forestry and Woodland Advisory Committees. Setting out what could be achieved by seeing all the trees in our urban environment as a

single collective forest, Jane Carlsen, the Urban FWAC Network chair said: “I am delighted that we have created a visionary document which sets out the man beneﬁts that trees o er to people in our towns and cities, and seeks to unite the whole urban forestry sector with a single vision.” www.forestry.gov.uk

FORST RELEASES NEW WOODCHIPPER Forst has extended its popular range of 6in capacity machines with the launch of the PT6, a new premium woodchipper developed speciﬁcall or pro essional contractors, arborists, landscapers and farmers. The PT6 is a robust and powerful woodchipper that has its own hydraulic system and reservoir, meaning the machine doesn’t need to be connected to a power

unit’s hydraulic system. The chipper is ideal for any professional with a power unit to drive the machine. Connectivity to a tractor’s trailer light sockets provides electrical power to Forst’s unique auto-intelligence control system, which operates the ‘no stress’ unction ﬁtted as standard to the machine. Doug Ghinn, director at Forst, commented: “The launch of our new PT6 woodchipper builds on the excellent reputation of our existing 6in capacity range and broadens our o ering to a wider market, making the Forst quality and performance available to those who don’t require a selfpropelled machine.” www.forst-woodchippers.com

An interview with

JOHN PARKER THE LONDON TREE OFFICERS ASSOCIATION As vice chair of the LTOA, John Parker helps to bring together the tree officers of London and beyond to expand their knowledge and share best practice. Pro Arb’s Fay Tate caught up with John to talk training, the industry and the EU referendum What is the main purpose of the London Tree Officers Association (LTOA)? Our purpose is to raise awareness and enhance management of the urban forest, although we are as interested in the tree officers as the trees. We think that looking after the urban forest is best achieved through management by tree officers. Our membership is around 150 tree officers from the London boroughs, local authorities and from outside London. We host quarterly seminars in London, although we are looking at holding them further afield. We always try to have someone from the LTOA speak – these seminars are free to members and they’re really good, high quality events. It’s a great way for members to keep up to date with current events in the industry and they also contribute towards CPD. Can you tell me a bit more about your role there and how it coincides with your job at Transport for London (TfL)? I’m currently the vice chair of the LTOA. Usually the vice chair steps up to become chair after two years, so hopefully that’s what I’ll be doing going forward. My main

role within the LTOA is supporting Richard Edwards, the current chair, who has been fantastic for the last couple of years.

As an organisation our main challenge is how we can best represent tree officers in the current political and financial climate My role at TfL is senior technical specialist for arboriculture and landscape. I look at the strategy and policies relating to our green estate and act as something of an internal

consultant, as well as supporting the arboriculture and landscape maintenance managers. These two roles tie in well together, as part of my role with TfL is to represent the organisation to the wider industry. What challenges do you face in your position as vice chair? I don’t have too many challenges to face because my main role is supporting the chair and Becky Porter, the LTOA executive officer. As an organisation our main challenge is how we can best represent tree officers in the current political and financial climate. I think the value of trees and green infrastructure has started to be better understood and

regarded by the public – people understand the value of trees, but what we’re trying to do is help people understand the value of tree officers as well. One of the things we like to say is that if you want a healthy population of urban trees, you need a healthy population of tree officers. The main challenge is to make sure we keep promoting and protecting tree officers. It’s also about how we can be seen as a voice of arboriculture. We also want to make sure we collaborate widely outside of London as we do have many members in the rest of the country. What have you achieved in the two years as vice chair and what would you like to achieve if you are elected chair? The last two years have been brilliant. Collaboration and communication will be key going forward, and working more closely with people who are doing the same thing as us but in different parts of the country and the world. I want to ensure that we continue to be seen as the experts of urban arboriculture but also in specific fields, including pests and diseases. The LTOA has been doing a lot of work with the Forestry Commission and Forest Research to survey for canker stain of plane in London – we’re building an expertise in that field and I’m keen to make sure we keep doing work and become recognised as the experts. Something we’ve been doing recently is getting more involved with the political side of arboriculture, such as by giving evidence to the Greater London Authority (GLA) Environmental Select Committee. I’m very keen to continue with this kind of thing.

Borough of Camden and one of the tree officers there, Al Smith, is one of the founding members. Do you offer any training schemes or opportunities for people to learn? Training is one of the big things that we want to take forward. We’ve started running sessions of bat training where we offer our members the opportunity to learn more about bat surveying, and we’re always looking at other training possibilities. Our seminars are something we’re really keen on, but what we do is voluntary, so people are attending our seminars in their free time. We’re limited to what we can do because of time constraints, but we’re lucky to have a lot of people who are willing to give up their time.

Trying to get people into the industry is a real challenge. The LTOA doesn’t do any apprenticeships but the London Borough of Camden offers a graduate volunteer scheme, and at TfL we’re offering placements to students and making sure graduates have the option of working with the arboriculture and landscape team. When I did my national diploma in arboriculture, I spent half of my second year on a placement at Richmond, which is where I learnt about tree officers. TfL is trialling working with colleges, including Capel Manor, Merrist Wood and Myerscough, to go ahead with placements in the future. What plans does the LTOA have for the future? We’ve got a busy year ahead. Perhaps the biggest thing we have coming up is the National Tree Officer Conference, which is being held by the LTOA and the Municipal

What is the history of the LTOA? It was founded in the early Eighties with tree officers coming together and discussing relevant issues. It has evolved since then and we have more formal meetings. It’s hosted by the London

Tree Officers Association (MTOA), facilitated by the Institute for Chartered Foresters (ICF), in November. The conference is going to focus on tree officers presenting to tree officers, sharing their ideas and best practice, and we’re all really looking forward to it.

I think the value of trees and green infrastructure has started to be better understood and regarded by the public We’ve got a trip to Italy in a few weeks to work with the Italian pathologists and find out how they cope with canker stain of plane, which will add to our expertise in this field. We also have trips set up, including one to Brighton for tree officers to find out how they manage the elm population there. There’s another trip planned to an arboretum in Malmo, Sweden. We’re going to carry on

with our seminars, too – we have another three this year, and will be releasing some more documents including one about salt damage to trees. What do you think are the main issues in the industry that need to be tackled? Pests and diseases are a huge current topic and we’re working closely with our partners in Europe to fight them. One of the main issues for a tree officer is austerity – the way we live and the threats to tree officers, operational budgets, cuts to tree services, all of that is a concern. The more cuts there are to local authority budgets, the more risks there are to trees. Who do you think should be tackling these issues? If the biggest issue is austerity, then it is essentially a central government issue. Pests and diseases involves everybody. Most of the issues relating to the urban forest can be helped by supporting and empowering tree officers rather than de-funding them. How do you raise awareness for arboriculture and what more can be done? As an industry we definitely need to be engaging with young people and schools, and the LTOA would be very happy to get out there to talk to schools and leavers. There is also work to be done on public perception of tree officers, as they are not always regarded in the best possible light by the general public – tree officers are often seen as people wanting to cut down trees, and that’s generally not the case. That is something the LTOA can hopefully address through our seminars and general engagement with the public and other industries.

Interview.indd 12

How do you think the EU referendum will affect the industry? The LTOA has started building good contacts in Europe – we’ve had European speakers come to our seminars and have been invited to speak in Europe ourselves. We are all dealing with the same problems. The EU places strict restrictions on imports and exports of trees, limiting the movement of species such as plane. It’s difficult to know what the outcome will be in either an in or out vote, but anything which compromises our relationship with our European colleagues wouldn’t be a good thing. From the perspective of the LTOA, we are keen to increase the amount of work with our European colleagues. How, when and why did you get into arboriculture? I’m from Gloucestershire – a countryside boy – so I spent my youth wandering around the fields and woods. Trees seemed like an interesting thing to get into so I went to Merrist Wood to study arboriculture. I did my college placement at Richmond, worked at Camden for a while and started at TfL in 2009 as an arboriculture and landscape maintenance manager. I did this for the central London area up until last year, when I became the senior technical specialist. I’ve been involved with the LTOA executive committee since 2012, and am currently doing my BSc in arboriculture and urban forestry online at Myerscough.

In the second part of his mini-series, Jonathan Hazell considers what information you need to collect during a survey

n this second edition of my series on tree surveys, I’ll be considering the design of the survey and what information ought to be captured. Sharing your understanding of the analysed assets with your client may require you to present information about each particular tree, as well as some form of pictorial representation of the tree’s position in relation to others, the built form or other assets. The data might be in a spreadsheet or table, and the graphic could be a photo, sketch, annotated drawing or layer on someone’s GIS. Just enough I can’t fathom the reason why, but measurements are one thing that clients always seem to view as highl signiﬁcant. or this reason I dutifully measure and record information that I might otherwise consider dubious. For certain common requirements, such as the tree constraints plan and tree protection plan for a development proposal, there is an agreed set of data to be collected, as listed in BS5837. There are particular attributes of these which seem to be

WWW.PROARBMAGAZINE.COM

TREE SURVEYS Part two collected less frequently and with less enthusiasm than others. For example, I rarely bother with ‘the existing height above ground level o the ﬁrst signiﬁcant branch and direction of its growth’, and if I consider a particular specimen to be in Category U, then I may not bother taking any measurements at all. You may decide to gather the information you need in a notebook, provided you have a structure to follow for each tree you assess. You ought to record the data that you need – going back for a few small pieces of information can be expensive. I used to use an A4 hardback book, but that was cumbersome and eventually I opted for a small spiral bound notebook which

could easily be slipped into my pocket in the (inevitable) drizzle and rain.

Remember to record just the information you need to address your brief – collecting too much is just as expensive as collecting too little For surveys where a large number of trees are being assessed, or where cyclical re-assessments will be made, it is probabl most e cient to use a handheld data logger with a pre-loaded survey schema. These will not allow you to save a record unless all the key facts and opinions have been recorded. A common template is the model from BS5837, particularly for an initial survey, but remember to record just the information that you need to address your brief – collecting too much is just as expensive as collecting too little. When assessing tree health and condition, observe local

targets and respect client concerns. If necessary, assess every part of the tree, the soil surrounding the tree and the local vegetation, alongside recording all of your observations. This review should be carried out in a systematic manner and every care should be taken to ensure nothing is overlooked – again, it is expensive to go back, and being careless or forgetful may damage your reputation. A much simpler instruction might be to advise on the position of a barrier fence. The key piece of data that you will need is the tree’s stem diameter; the condition of the tree might not matter if, for example, the tree is in third party ownership. ABOUT JONATHAN HAZELL Jonathan Hazell’s career began on the tools with the Ealing tree gang in 1980. Senior roles in the public, charity and commercial sectors followed and in October 2011 Jonathan established his own arboricultural consultancy practice. www.jhazell.com

sh dieback (Hymenoscyphus fraxineus) is already infecting many ash trees in the UK and will cause the mortality of many of them. Another threat speciﬁc to ash is the emerald ash borer (EAB, Agrilus planipennis), which thankfully hasn’t arrived in the UK or other European states at the time of writing. It is spreading in our direction from its native Asia, having passed Moscow. This beetle causes high mortality of ash trees and together with ash dieback could lead to the extinction of the ash tree in the UK and Europe, according to some scientists. The pest EAB’s native range includes China, Japan, eastern Russia and Korea. Here it infests weakened (stressed) ash trees, as well as some elms and walnuts, but not to pest proportions. It was found in the US in 2002, infesting native ash trees. It can be transported through infested wood and introduction was likely via packing material from Asia. Infested nursery stock also poses a transport risk. EAB larvae feed on the outer sapwood of ash trees and can rapidly girdle (ring bark) stems and branches. dentiﬁcation Adult beetles are approximately 1.25cm long. Larvae are segmented at worms which can reach 2.5cm in length. EAB has a similar appearance and life cycle to other Agrilus borers.

trees in Europe and the UK, further complicating any UK situation. osing thoughts If EAB reaches the UK we will need to have strategies and pesticides ready to control it. Treatments for ash dieback are required as a part of this. We are unlikely to preserve our natural ash tree population even so,

The introduction of the emerald ash borer from Asia would exacerbate the already dire situation of ash dieback in the UK, says Bartlett Tree Experts io og In the US, adults generally emerge from infested wood in June and early July, leaving visible ‘D’ shaped holes. They can hal a mile or more to other hosts. They feed on ash leaves, causing notching, and lay eggs in bark crevices. Hatchling larvae bore through the bark into the tree’s cambial area. Here they create winding feeding galleries, overwintering afterwards. anagement t is di cult or conventionall applied pesticides to reach larvae inside sapwood. EAB treatments are most e ective when

applied preventatively. American treatments use insecticides that spread throughout the tree. Stem injections of emamectin benzoate are usuall e ective in controlling initial stage EAB infestations. Soil applied imidacloprid is often used in combination, preventing reinfestation. However, imidacloprid’s use on trees is banned in the UK and beyond. Emamectin benzoate is also not currently registered for use here. If EAB does become prevalent within UK landscapes, then consideration of approval for this product may be warranted. Further management includes removing heavily infested trees and destroying them by chipping, burying or burning. Good arboricultural practice and plant health care to maintain the health of ash trees, including pruning, fertilisation, mulching and irrigation in droughts, can reduce stress and improve the tolerance of trees to EAB attack. Ash dieback also means there are many more stressed ash

but we may be able to keep those in towns and cities which are most culturally valuable to us protected. The natural spread is slow enough to give us plenty of warning, but the transport of infested material could mean we aren t a orded this lu ur .

Check the tree is covered by a Tree Preservation Order (TPO), initially with the client who may know, or with the LPA if they don’t. Be aware of conservation areas, too – they aﬀord protection to trees which, if contravened, are similar to TPO.

TOP TEN TIPS APPLICATIONS

FOR TREES WITH A TPO

Give clear reasons for the work, such as: to increase light to garden, avoid low branches being damaged by passing vehicles, suppressed specimen should be removed to allow stronger tree to develop and mature, etc.

Use the correct form, Andy Poynter of Ian Keen Ltd offers his Top Ten downloadable Tips on filling out and presenting applications for from the Planning works on trees under Tree Preservation Orders Portal or the LPA website. There will also be accompanying guidance to assist If you are applying for felling then, with completing the form eﬀectively. where appropriate, advise which www.planningportal.co.uk tree is proposed as a replacement.

Tree work specifications must be clear and measurable, with either finished dimensions or current dimensions with extent of pruning specified. Annotated photographs are useful to include. Fixed structures can be incorporated into specification: prune to clear light by 1m, prune to clear building by 2m, over road by 5m etc.

Demonstrate your arboricultural knowledge. If replacement planting is inappropriate, state why.

Supporting information: if the reason for the works cannot be readily seen, then you must provide suﬃcient information, often third party, to demonstrate the reason. Such circumstances for this information typically include internal decay and building subsidence.

Use current terminology – generally this should follow BS3998 language. If other terms are used, then you should explain them – demonstrate your understanding of quality pruning rather than just stating ‘works in accordance with BS3998’.

Avoid percentages in crown reduction speciﬁcations. This style of specifying work has been withdrawn from current guidance and is likely to result in your application not being validated.

If you are unsure, contact the LPA’s tree oﬃcer. While pressed for time and resources they will often invest their time to ensure a better quality of application is received. Finally, remember to ‘be realistic and professional’. Any application will be publicly available online – your reputation is essential to your career in the industry.

PRO ARB ON TOUR

STIHL

On 18 April, STIHL GB invited members of the press for tours around two of its production plants in Switzerland and Germany. Pro Arb’s Joe Wilkinson reports back from his trip to Europe where he was given a first-hand look at where STIHL’s famous orange products are made Leading the UK press for the trip, managing director Robin Lennie, head of marketing Simon Hewitt and PR and communications manager Rebecca Rassie gave us the opportunity to tour the chain making facility and production factory of STIHL. A press conference was also set up with Dr Nikolas Stihl (pictured left), chairman of the advisory and super-advisory board at STIHL, and grandson of the company’s founder, Andreas Stihl. Founded in 1926, STIHL celebrates its 90th anniversary this year. It is still the only chainsaw manufacturer in the world which produces the majority of its own parts in house. Over 70 types of saw chains are

manufactured in Wil, Switzerland. The raw material for the chains arrives as a roll of steel which is put through a machine specially designed and produced by STIHL, and is made into one of three parts: the cutting tooth, connecting segment and drive link, which is the integral part of the Oilomatic lubrication system. At every step of the process, from the cutting teeth leaving the machine to final assembly, there are quality control checks to ensure that every chainsaw meets the high STIHL standards. Over in Wablingen, Germany, it’s the same story. The raw material, along with more specialist parts such as the pistons, is manufactured from beginning to end by STIHL, all through machinery also created by the company. The plastic comes in from the

supplier to be heated and moulded into shape before joining the assembly line to be meticulously pieced together. The company has a turnover of €3.25bn (£2.5bn), which the team sees as the result of their long term strategy. Recently, €1bn (£780m) has been invested back into the company, allowing for the expansion of the factory in Wablingen and the increase of the research and development department. STIHL has always played a large role in the development of cordless technology, and with 15% of its market now in the battery operated sector, they are expecting an increase to 25% by 2020. STIHL will also be launching its new range, the Compact Cordless System, this summer. For more information on STIHL products, visit www.stihl.co.uk or call 01276 20202.

Each month we feature an ancient British tree. This month the Ancient Tree Forum introduces us to the...

Hollow oak, Burghley Park, Lincolnshire The Ancient Tree Forum’s spring visit to Burghley Park this year had three aims: to celebrate a Capability Brown landscape rich in ancient and historic trees, see the conservation work being done there, and discuss what more might be done

for their sustainable management. 2016 is the tercentenar y of Capability Brown’s birth, and Burghley is one of his most intact landscapes. His work there, spanning 25 years, included creating a river-like lake and planting trees to frame naturalistic views of the house and park. Many of the old trees in the park pre-date his landscaping, and some are even older than the house, which was built between 1555 and 1587. As well as appreciating their aesthetic value, Brown recognised that pre-existing trees reinforced the history and continuity of ownership. One of the park’s most special ancient trees is this very large, hollow oak pollard with a 9m girth, which is thought to be at least 800 years old, and

The tree is thought to be at least 800 years old and is still in excellent health, with a very large 9m girth

is still in excellent health. It is likely that pollarding of the tree stopped in the nineteenth century when the practice became unfashionable, and since then the crown has

developed long, heavy lower limbs. Some time ago, the tree partially uprooted and developed a signiﬁcant lean, so that the lowest limb is almost in contact with the ground. This branch has continued to lengthen and increase in girth. Discussion on the trip focused on whether the weight of this massive limb might be a risk of causing further or total uprooting, and if so, what management might prevent this. One suggestion was to build a raised area enclosed by a dry stone wall and ﬁlled with soil, on which the limb would rest. Opinions varied as to the best management options for the tree, but the consensus was that the oak appears to have achieved a natural balance itself, and any method chosen will to some extent change this dynamic. Management techniques for veteran trees are fully explored in the Ancient Tree Forum’s handbook, ‘Ancient and Other Veteran Trees: Further Guidance on Management’ (available from the ATF’s website). The book includes guidance on recognising the value of veteran trees in relation to landscape and heritage, and explores in detail a range of

management practices. The ATF champions the biological, cultural and heritage value of Britain’s ancient and veteran trees and promotes best practice in their management. www.ancienttreeforum.co.uk
