Australian Arbor Age August/September 2024

Still growing

Iadmit to a real sense of shared joy in welcoming Arboriculture Australia to the fraternity which gathers around this magazine.

I’ve personally been very fortunate in the support and friendships which have formed with various association representatives across the country since I started on this title. The knowledge all the professional tree carers and arborists are happy to share with someone keen to learn is quite humbling.

And while all the associations are doing excellent work in stabilising the industry and putting in place the regulation it needs and deserves, there’s no denying Arboriculture Australia – ‘Arb Aus’ in everyday conversation – is the heavy hitter in arbor associations in our region.

To be invited to a board meeting to discuss how the alliance would progress was very gratifying indeed, and to see

the breadth of skills available from the various board members was an eye opener.

We can look forward to input from Arb Aus starting in the October/November 2024 issue.

Meanwhile, thinking of associations and recent eye openers, it’s difficult not to feel alarmed and concerned at Dave Crispin’s excellent piece from Arb West. Climate change is undeniable and a concern for everyone, but Dave’s thoughts and observations bring the matter to a real and relevant local focus.

As for an eye opener, Dave’s revelation of the 300m blast radius for a hazard zone around a lightning-struck tree had me sitting up straight in my plush office chair and taking notice, I can tell you!

Dave’s thoughts are just part of another great issue, of course. As always, Jim McArdle and the TCAA have their collective fingers on the pulse of the arbor world and are fighting

hard for muchneeded industry recognition, the QAA continues to lead the charge with excellent competition and training opportunities,

Brian Beecroft at the TTIA offers his usual insightful demystifying of some legal matters relating to those working with timber, Cass Humphreys has more thought-provoking ideas and suggestions, and there’s a wealth of great equipment and machinery featured.

Meanwhile, next time there’s a storm brewing, stay at least 300m away from tall trees.

In fact, it’d be a good time to stay inside and read this magazine.

Dragon’s Blood

The Socotra Dragon tree – or Dragon’s Blood tree –(Dracaena cinnabari), is thought to be named for the blood-like colour of its red sap.

Endemic to the mountaintops of the Socotra Archipelago, a group of four remote islands located in the Indian Ocean south of the Arabian Peninsula, the Dragon’s Blood tree exudes a red sap which forms a resin prized as a medicine and as a red dye in ancient times.

Dragon’s Blood resin is still used as a varnish.

Popular in Australia

A variety of the Dragon’s Blood tree, Dracaena draco, is popular as a landscaping feature plant in the NSW south coast and Sydney regions.

The species has been successfully propagated in Australia from seed, but can take up to a century to grow to a large specimen. Such large examples will often command prices ranging from $5000 to $100,000.

Piranha Chippers

A new chipper has hit the Australian market. Piranha Chippers’ BT300 is Australian designed and built, and ready to tackle the toughest timbers and conditions the Wide Brown Land can throw at it.

The Piranha Chippers BT300 is powered by the 4HK Isuzu turbodiesel engine which produces a classleading 197hp. This power is sent to the 650mm diameter cutter drum which weighs 400kg with four staggered cutter knives and with a 390mmH X 500mmW (16" X 20") direct opening into the cutterdrum housing (no step downs).

The BT300 will outperform any other 12" chipper available in today’s market, and indeed has more horsepower than most other 18" chippers currently sold. Being a state-of-the-art, electronically controlled common-rail direct-injection diesel motor, the 4HK provides amazing fuel economy and is also very quiet when running. Dual horizontal infeed wheels offer incredible pulling power, and, with the assistance of the hydraulic

winch (which quickly folds up out of the way when loading), difficult trees and branches are quickly dealt with, using minimal physical effort from the operators. Other features that ensure ease-of-use include the hydraulic autoengage clutch, hydraulic dischargechute swivel and the hydraulic tailgateraise-and-lower functions.

Cutting edge

The BT300 was designed and built for pro use: economics and ergonomics were both included in the design brief, and the result is a chipper ready to not only work hard, but with fast, easy access for essential servicing.

The tried and proven Isuzu 4HK diesel has 500-hour service intervals allowing longer between scheduled oil and filter

changes, and with Isuzu trucks being a popular choice in the arbor industry, shared filters makes for efficiency of stockholdings. Many essential engine service parts can be shared between the BT300 and the tow vehicle.

The front door of the BT300’s engine compartment gives access to all filters and service points, and the remote oil-drain hose makes draining the engine oil quick, easy, and mess-free. The access door at the top of the engine cover means replacing oil is just as swift and trouble-free an operation, and a work light mounted inside the engine bay makes checking and servicing an efficient, minimum-time operation.

The knives, an essential service item on any chipper, are accessed via the side walk-way ramp. With the chipper

housing hood open, the top part of the cutter drum is completely exposed. Servicing the knives is extremely easy and safe.

Piranha is quality

To ensure the highest quality workmanship, Piranha’s professional welder tradespeople are independently tested and NATA certified to AS/NZS 1554.1 welding standards. Australianmade structural-grade steel is used in

all components of Piranha’s chippers, and some of the leading features that set apart the BT300 include:

• Twin-axle trailer design gives double the braking power and flotation over soft surfaces compared to single-axle units

• Load-sharing ‘Soft-Glide’ leaf-spring suspension provides a superior ride compared to a single-axle trailer and doesn’t send violent feedback through the drawbar into the tow vehicle, and

• Heavy-duty all-terrain tyres on tough, steel rims.

Piranha’s ‘Posi-Arc’ infeed-arm pivot design means the large top infeed wheel aggressively climbs towards the incoming timber, up and on top of the trunks and brush, through the natural, positively inclined arc the unique feedarm design provides. This makes for a strong feeding action, allowing the Piranha to pull in difficult branches, twisty timber and whole trees with ease.

The unique staggered four-knife

with a 650mm diameter and integrated highvelocity fans give a superior chipping action and a very strong chip discharge.

Changing the knives is very easy and practical. Image: Piranha Woodchippers

damage if the blades encounter foreign material fed into the machine and they can be easily replaced if ever required.

Quality build

All manufactured sheet-metal steel parts are individually primed and painted before assembly for superior, long-lasting corrosion protection, ensuring the Piranha will continue to look good and perform flawlessly for decades.

Piranha chippers come standard with many features that work together to reduce the operator’s fatigue and stress, including:

• Hydraulic auto clutch

• Hydraulic winch

• Hydraulic tailgate raise and lower

• Hydraulic 360° discharge chute (continuous swivel)

• Twin (top and bottom) horizontal infeed wheels

• Central grease-station hub

• Full-sized spare wheel, and

Morbark and Hilltops Vegetation Services

In a fleet of hardworking machines, the Morbark Beever 1821 turned out to be a crew’s favourite.

The Morbark Beever 1821 18" capacity wood chipper is a high-capacity, high-production chipper which includes more standard features than any other chipper in its class. Image: Monitor

Features include a live hydraulic system with ball valve, pump, motor, and valve bank, with an additional pre-plumbed valve section for installation of an aftermarket winch package. Image: Monitor

Based in Young, NSW, Tony Pullen went into business for himself in 2017. Seven years later his company, Hilltops Vegetation Services, has grown considerably.

“We kicked off with just myself and a trailer and a 12m cherry picker,” Tony recalled.

“Now we’ve got 10 employees and a heap of gear.”

Those employees and equipment aren’t only involved in tree work. Hilltops Vegetation Services offers a wide range of forestry and propertymaintenance expertise, including vegetation management, largearea mowing and work for councils, Transport NSW and residential and private work.

The equipment required to offer good service in those areas is varied, and Tony listed a few of the main machines in the company’s fleet.

“We have a brushcutter, a positrack and an excavator with a slasher head…” he searched through his mental files, “and an 1821 Morbark.”

Morbark Beever 1821

The Morbark Beever 1821 18" capacity wood chipper is ideal for residential tree services, utility line clearing, vegetation management, maintenance contractors and municipalities. It’s a high-capacity, high-production chipper which includes more standard features than any other chipper in its class.

The Beever 1821 is also available tracked for right-of-way clearing, highway clean-ups and hard-toreach areas requiring a self-propelled unit for material access. The powerful TorqMax™ dual feed-wheel compression system generates more than 6600lb/ft (9822kg/m) of material pulling force, and many customerinspired innovations are featured, increasing efficiency and safety while reducing operating and maintenance costs. The unit is pre-plumbed and outfitted for the easy installation of most aftermarket components, and an ergonomic infeed design provides consistent feed control bar activation.

Like all Morbark equipment, the 1821 is a long-lasting, durable machine backed by a world-class parts-andservice support team.

Long service

Tony and the Hilltops Vegetation Services crew have more than one chipper in the fleet, but the Morbark 1821 has been the go-to machine for quite a while.

“We got it in 2019,” Tony explained.

“We haven’t had much downtime with it – just the odd little bits and pieces that go with a machine that works so hard. It’s been awesome.”

After the years of hard work Tony did think about upgrading the 1821, but he ran into a small difficulty.

“All my guys love it,” he chuckled. “I was actually going to trade it in earlier, but the boys on the crew talked me out of it. They told me to hold off because they really like it, so I’m holding back a bit.”

What is it they like so much, we wondered?

Tony supplied the answer: “I think it’s just the ease of use and how well it performs.”

Morbark Beever 1821 features

• Dual horizontal feed wheels with TorqMax top-feed wheelcompression system, hydraulic lift assist, variable-force constant hydraulic downpressure system with additional manually applied hydraulic down pressure at the valve handle and direct-drive bottomfeed wheel with torque-arm coupler

• Live hydraulic system, including: ball valve, pump, motor, and valve bank with additional pre-plumbed valve section for installation of an aftermarket winch package

• 3" (7.62cm) x 5" (12.7cm) tubularsteel telescoping drawbar with two 12" (30.48cm) extensions

• Morthane paint system – a chemically cured, electrostatically applied urethane coating with high-gloss finish, built-in UV protection, chip and chemical resistance and corrosion protection.

The next step

The 1821 will eventually have to be replaced, and Tony is considering his options. A big point in the favour of staying with Morbark is the service Hilltops Vegetation Services has enjoyed from Monitor.

“They’re a bit far away from where

we are, but we’ve got Monitor guys that work on the Morbark and we have no issues. Our contact, Stuart Samson, is great.”

After a little careful thought Tony summed up his position.

“I’m happy to go with Morbark again. I’d definitely buy one.”

CMC aerial platforms: perfect for arboriculture

Agile, robust, versatile and safe, CMC spider platforms meet every need of tree-care professionals.

First among CMC’s distinctive features is the ability to access areas otherwise impossible to reach.

Born from the most advanced lifting technology, CMC aerial platforms perform in all conditions, offering solutions and overcoming obstacles difficult for a truck-mounted platform.

Go anywhere

First among CMC’s distinctive features is the ability to access areas otherwise impossible to reach as they can reduce their dimensions to the point of passing through a simple door, slipping under an awning, or traversing a narrow corridor to access a residential yard.

All this while moving autonomously on their tracks controlled by the operator via wire or radio control (depending on the model).

Not even a small operating space poses a problem. CMC aerial platforms are designed to adapt to the available space, achieving the best possible stabilisation, both in open fields and in the tightest and narrowest places.

As for levelling, it is difficult to find perfectly flat terrain in nature, and this can often be a major obstacle to the safe use of truck-mounted platforms.

However, the hydraulic stabilisers of CMC aerial platforms can perform the operation simply and quickly, especially with the Self Control System by CMC, an autopilot for MEWPs, forming the base to work perfectly on any terrain.

Height

With working heights ranging from 13 metres to 41 metres, and an aboveaverage lateral reach, CMC spider platforms prove to be up to any task, allowing for easy pruning of any tall tree.

This is also thanks to an excellent manoeuvrability and easy and intuitive control features, both in full hydraulic versions and in those equipped with technologically advanced guidance systems that include automatic closure of the aerial part.

Thanks to their low weight and the availability of non-marking tracks, along with special support plates at the base of the stabilisers, CMC aerial platforms prove to be the perfect choice in even the most delicate missions, such as public and private gardens, courtyards, or golf courses.

Built for pro use

Last, but certainly not least among CMC’s advantages, is their great ease of transport. CMC aerial platforms are self- loading and easily transportable on trailers, thanks to the excellent balance between robustness and low weight.

“For us, this means being The Specialifts, the specialists in spider aerial platforms,” declared Alessandro Mastrogiacomo, CEO of CMC. “We are able to design and manufacture efficient work tools that respond perfectly to the controls and meet the specific professional needs of our customers.”

First conviction highlights liability

Brian Beecroft of the Timber Trade Industrial Association underlines the importance of understanding and compliance with new legislation.

An ill-judged decision that caused the death of a young employee has resulted in a small business ending up with a $1.3m fine. A court found the sole director must pay $120,000 compensation to the family and complete two years’ unpaid community work.

The accident occurred when the director of the Melbourne stonemasonry was using a forklift to move an empty A-frame rack. He was driving the forklift across a sloping driveway with the load raised when it tipped over and crushed the 25-year-old, who had been trying to steady the swinging load.

The young worker was working with his father in a business using the same warehouse as the stonemasonry, and over the previous decade the

two businesses had regularly worked together.

Security cameras in the company’s warehouse and across the street captured footage, described in court as ‘harrowing’, as the forklift tilted and fell, pinning the 25-year-old under it.

The director of the stonemasonry called for help and the young man’s father rushed over to find his son crushed under the machine. When it was lifted, the director and others tried to unsuccessfully to revive him.

First conviction

The company was prosecuted under section 39G(1) of Victoria’s Occupational Health and Safety Act 2004, which provides that a person must not engage

in conduct that is negligent, constitutes a breach of duty owed to a person and causes the death of that person.

The new provision, introduced in July 2020, carries a maximum penalty of 25 years imprisonment for a person, or 100,000 penalty units (almost $18.2 million at the time of the offence) for a body corporate.

The director was initially charged with workplace manslaughter, but the charge was subsequently transferred to the company. In Victoria’s Supreme Court, the director pleaded guilty as an officer of the company to a less serious offence, admitting liability for the failure to take reasonable care which resulted in the breach of the workplace manslaughter provision.

In court WorkSafe’s investigators submitted it had been reasonably practicable for the stonemasonry company to reduce the risk of serious injury or death by ensuring the forklift was driven with the load as low to the ground as possible, only driven in reverse down slopes or inclines, not driven across, or turned on, slopes or

inclines, and only operated when other people were at a safe distance.

The failure to ensure the forklift was operated properly was negligent because it fell well short of the standard of care that would have been taken by a reasonable person in the circumstances.

The director admitted he had not followed safety guidelines around

operating forklifts on a slope.

The director had told WorkSafe investigators he ‘never thought it’d be that dangerous’. He said he didn’t understand how the accident had happened, as he had told the young man to stay clear of the forklift.

He also said he’d shouted at him to ‘get back’ as the forklift began to tilt,

and that ‘maybe he thought he could hold it’. This indicated that the director realised the young man was close to the forklift, which is another departure from safety guidelines – forklifts should only be operated in an exclusion zone with people kept at a safe distance.

In Victoria’s Supreme Court, Justice Michael Croucher said the negligent conduct itself was very brief, occurring over a number of seconds.

Justice Croucher noted the director had cooperated with authorities, entered an early guilty plea and showed remorse for what had happened. He had ‘deep feelings of sadness and guilt’ and had provided significant financial assistance to the young man’s family, including paying almost $17,000 for the funeral.

Justice Croucher fined the company

$1.3 million – a sum significantly greater than the company’s assets – and ordered the director to pay the young man’s family $120,000 in compensation, as well as completing a forklift operation course and a two-year community corrections order, under which he will have to do 200 hours of community service.

What it means for tree contractors

While this case deals with a forklift, it could just as easily apply to equipment and machinery used by tree contractors. Duty holders face serious personal and financial consequences if they do things that put the workers’ health and safety at risk of death. TTIA Members in other states are also increasingly affected by industrial manslaughter legislation.

The TTIA WHS unit Manager, Ken Hocking, is able to assist in safe-work policies and procedures regarding the operation of forklifts.

TTIA has a fully functioning in-house WHS unit which is there to support TTIA members nationally, and the association has long-term experience in the treecontracting industry.

A new board for the TCAA

TCAA regular Jim McArdle updates the arbor industry with some news and points of discussion after the latest TCAA AGM.

After the 2024 AGM’s success the TCAA has a new vision: ‘Top of the Trees leaders in arboricultural excellence’. The committee now serving includes Dan McArdle, Bruce Smith, Carson Smith, Jeff Hunt, Murray Bolan, Greg Major and myself, Jim McArdle, as the new incoming president, and that committee is considering the following points as urgent matters for attention:

* The issues with the Code of Practice and SRT are noteworthy where the construction industry and managers of second-tier contract firms try to classify our industry with construction COP;

This is not the suitable. Arborists are not construction workers, but a breed of our own. We have specialised SWMs, specialised training, specialised knowledge and we are a specific industry;

• The discussion around apprenticeships is open again and we need a new award to bring apprenticeships online. This should be a big boost for the whole industry as, being short on staff, we can guarantee job security. We can also guarantee good mentors and training through TAFE and our other partners.

• Apparently the arbor industry has been removed from the list of critical skills shortages by the Labor government. How is this possible when our training numbers and totals of completed enrolments are pitiful? It also means practitioners through the industry will have to get on the same page over this common theme;

• It would be wise for the other industry partners to also review this information and be active over the detrimental issue of unlicensed and untrained people in the arbor industry. They are still going to job sites, still going to schools, and still going to utility companies. This is why our injury stats are high across the arbor industry and why bad press is news, including featuring ‘tree loppers’ on the ABC in Killers in the Suburbs on July 6, 2024.

Training in the old days

Historically, thinking of the arborist taught and mentored me, it was my dad. He made me stay on the ground for three years before doing AQF 1 with Bruce Mcleod at Ryde TAFE, completing the Hort certificate. I felt like it was an apprenticeship with this additional training, and I was confident in my work thanks to the training I’d received.

But as I was learning there were some real characters who showed me many methods and philosophies in climbing, and some of the more high points make great memories for me now. I still remember Jim McArdle (senior) scampering up a huge blackbutt, and one of the lead climbers climbing with a small hessian rope and, while getting their balance on a limb, walk, then flip their beltloop around twice to stand on a spot on the limb while cutting the same limb.

That’s Adrenaline 101! It takes seriously good balance.

There was a climber who utilised ladders in a tree, which still puzzles me.

Of course there was Joe, barefoot and in jeans, who climbed a tree, and Carl who pioneered the team-leader role and was somewhat talkative and let

Newly appointed TCAA president, and Arbor Age contributor, Jim McArdle.

everyone know their exact job. Rick, who was very methodical in takedowns but had unusually short sentences.

All these people put in a good effort as contract climbers, and all before formal training started at TAFE.

When spikeless climbing was introduced, we found that the energy required to scale the tree was much greater. With new methods and new forms of safety we began to ask questions like, “Where’s the high point and is it load bearing?”

Along the journey

Fast forward to the day when we ask, “What skills does a good arborist have?”

The most-needed skill is clear thinking – resolving a problem in reducing weight and bringing down loads, including the arborist. safely to the ground.

What experiences have I had which I wish I didn’t?

* Getting caught up a tree in a storm which was blowing fiercely

* Hearing my brother’s story about climbing a moving tree which was tied down the day before his birthday, and

* Hearing the pain in several mates who lost someone from a tree dive.

With the exposure to the new training platforms there is discussion that apprenticeships will be created to endorse training for the trade level. With this in mind the programme AQF level 3 is recognised as a good profile for the trade arborist. TCAA is currently in discussions with ITAB, and its odd how other associations have limited participation on this discussion.

Some of the old methods, just like some of the trusted old machinery, need to be admired, but set aside.

TCAA board member David McArdle oversees staff training.

The TCAA will keep pressing for recognition of arboriculture as a profession in its own right. Industry members can’t afford to sit around and vegetate.

Important questions

So what does make an arborist a good arborist?

Experience and being knowledgeable, for sure, and doing the job efficiently and productively, reviewing practices for improvements. Making others follow instructions is important, including a regime of taking vegetation away to be disposed in the chipper, clearing spaces with the drop zone or building up debris which could be used to cushion larger pieces without damaging the hard surfaces.

My brother, Matthew, states a good arborist is “…one that doesn’t get hurt”. What’s the price for a good arborist when quoting industry rates per hour?

A fair price for a contract climber was established within the TCAA. Some climbers expect to be around the high pay range, but most would be earning well above the average wage per day. It’s dirty, dusty, dangerous work. For the lead arborist, the groundies’ lives, client’s property and lives of all on the site are in their hands.

So, what makes a good arborist?

Reliability, safety, honesty, being drugfree, being alcohol-free, experienced, having tools in working order with sharp chains, and having the correct PPE that is effective and light carry. The arborist must be able to envision the way the job is going to go and be able to estimate the time to remove the tree, and if they need the job safety reviewed, work method adjusted, additional help or equipment. The arborist must keep up to date with current trends be aware of legislative changes that affect tree preservation. The arborist must ensure their gear’s

A good arborist will always be aware of tress in his surrounding, like these street trees in Leura, NSW.

Being a good arborist means honing the skills learned as an AQF 3 arborist without the pressure.

The best arborists now are the ones who can take more care, are very aware of their surroundings and spend less time at heights within a tree.

When spikeless climbing was introduced the energy needed to scale a tree was much greater.

stored correctly and has no damage and that it is tagged and in time stamped for compliancy.

The arborist makes available the contact details of another nearby backup arborist to call in case of an incident.

The best arborists now are the ones who can take more care, are very aware of their surroundings and spend less time at heights within a tree, and ultimately being a good arborist means honing the skills learned as an AQF 3 arborist without the pressure.

What’s in a name?

An ‘arborist climber’ means someone with strong limbs and useful muscles, a level of fitness and who has a resilient mental capacity to complete a difficult task.

‘Technology’ in arbor means utilising climbing mechanical ascenders to reduce fatigue, and utilising an EWP when the job requires pruning or reduction without having to out climber at risk.

‘Communication’ is allowing CB radios, walkie talkies, and mobile phones to communicate clearly and effectively so the experience of taking down or pruning is unhindered by a fault of mistake. Flashing a mirror to get the arborist attention in a high climb is not acceptable. Throwing a stick at the arborist is also not acceptable – even though it was used effectively in the past.

The use of the laser to assist in referencing what is essential to prune and material to be retained by the supervisor is also an excellent communication tool.

What ‘mistakes’ can an arborist afford to make?

None.

It’s a bit like a submarine captain. If the captain goes down then the whole team suffers.

What about the toolbox meeting in the morning, the lunch break and the afternoon tea/smoko? These are all enshrined in arborist’s sacred time to reflect on the job and get sorted over current issues or difficult parts of the job. Nobody wants a branch through their roof or window, and nobody wants to have hospital time.

Both views

‘Scars’ on arborists hint at something that got too personal. It tried to take a piece of the arborist with it. Or there may

be the scars from laughing about the day you don’t know how it was done but you did it?

We used to take massive pieces down moving large limbs across buildings to be laid gently in a landscaped yard, and it would always get an accolade from the residents. Calculations were very rigid, with having a second experienced arborist comment on weights, knots and loadings was essential.

When thunder roars, lightning pours

Dave Crispin, senior arborist at Treeswest Australia and Arboricultural Association of Western Australia (Arb West) committee member, has observed the trend in climate change showing in trees.

Perth recorded just under 22 millimetres of rain between October 2023 and March 2024, the city’s driest period since rainfall records began almost 150 years ago.

Comments like, “Have you seen all the trees that are dying up in the hills?” or “Why are all our trees turning brown and losing their leaves?” have been common topics of conversation over the past several months. Perth has a Mediterranean climate: hot dry summers and wet, cool, winters. Or it used to be.

Now that is definitely not the case.

Decline

Over recent years the ‘wet’ has become less and less, with minimal recharge into the natural groundwater. ‘Recharge’

refers to the recharging of groundwater that supplies up to 40% of Perth’s water, which is mainly used for drinking and commercial use.

The fact is, it’s been declining since the 1960s, with fewer significant storms carrying any decent amount of rainfall. This decline has been studied by Dr Simone Gelsinari and his team at UWA (University of Western Australia), revealing a drop of nearly 70% in the past 50 years.

“Our findings suggest groundwater aquifers in climates like Perth’s are particularly vulnerable to climate change, and may see larger recharge declines as soil needs to be saturated with rain before water trickles down to aquifer level,” Dr Gelsinari said.

It’s a sobering thought.

Drying up

Looking up into the Darling Scarp, named after the Governor of New South Wales, Lieutenant-General Ralph Darling, you would typically see a blanket of green, even in the height of summer. Now there are large patches of brown wherever you look, and huge stands of dead trees.

The scarp is part of the jarrah forest region, consisting of mainly Eucalyptus marginata, Corymbia calophylla, Eucalyptus megacarpa, Eucalyptus patens and Eucalyptus wandoo. The concentration of a species depends on which side of the slope, or whether in a high or low area.

In conversations with other arborists, it seems the juvenile and semi-mature trees have been hardest hit, not having

enough time to develop a deep enough root system to tap into the belowground water source. All these trees are vital for the local ecosystem, whether a food source, habitat, or roosting trees for local fauna. The ubiquitous Lophostemon confertus, so prized for its hardiness as an amenity tree, its ability to withstand harsh pruning, and being drought tolerant, seems to have fared the worst. I’ve lost count of how many I’ve seen dead or in a state of rapid decline. I say ‘rapid decline’ because it looks like they’ve been poisoned.

Towards the end of March I was asked to look at three Brush Box trees on a road verge. As I arrived, my first thoughts were that they looked like a typical case of Glyphosate poisoning. All the leaves were still intact, but all necrotic, with not one green healthy leaf remaining.

Unfortunately, this was not an isolated case. All over Perth numerous Queensland box trees were falling victim to the drought. Maybe it’s time to reconsider the long-term future for our Lophostemon confertus?

Lightning strikes

Another consequence of our changing climate is the increase in lightning and the strikes on trees.

Global warming influences the frequency of lightning strikes. For every one-degree increase in global warming

We need to partner with local and state governments to offer our expertise and guidance on sustainable tree management policies and urban greening strategies “

there is a rise in strikes of approximately 12%. In a recent study by the University of California, Berkeley, researchers found if conditions continue to warm at the rate they are, by the year 2100 we could see a rise in strikes by a staggering, 50%.

How many of our tall trees would we lose?

Australia has been identified as one of the countries that will be most affected by this phenomenon.

Recently, an Arb West member attended a remote mine site to carry out a routine assessment on the health and structural condition of several trees around the accommodation block. At this remote location a huge corridor of trees had been cleared, except for a few token trees dotted here and there. The trees were mainly Corymbia

calophylla or Eucalyptus marginata, and each stood like a sentinel, their prominence in the landscape obvious by their size and height. Each tree was in excess of 100–150 years of age. Almost 50% of the 90 trees had been struck by lightning at some stage. Black scarring was evident on the trunks and branches to varying degrees. Recently, a large, 25m, Corymbia calophylla, with a canopy spread to match, was struck by lightning. The tree exploded, sending tree parts 300m away and damaging the accommodation block with pieces of wood embedded in the roof sheeting. A total of 10 cars were written off, with many others considerably damaged. One dual-cab utility had a piece of wood the thickness of a human thigh and two metres long spear through the rearwindow panel and embed in the front dash. Fortunately, no one was around

at the time as the workers were still on their shift.

A blast radius of some 300m! Imagine if anybody was close by. They were extremely lucky.

High pressure

When lightning strikes a tree it’s not always game over. The species, the type of lightning (forked or sheet), and whether the tree is dry or wet, can greatly affect the outcome. According to Dr Gregory Moore, a University of Melbourne researcher, if the conditions are against the tree and it gets struck directly, potentially, up to one-million volts can flow through the tree, instantly raising the temperature to 20,0000ºC. The tree is a sealed system, with the flow of sap (mainly water) passing underneath bark near the surface, so when the lightning strikes the sap, it

instantly turns into steam, the tree acts like a huge pressure cooker and literally explodes.

It’s not a good place to be when lightning is close by.

Not a forgone conclusion

Not all trees struck by lightning die instantly, some may take a couple of months, or even a year. If the tree’s natural defence system has been compromised, the potential for harm caused by pest or disease attack is greatly increased. If the lightning went to ground via the roots, it is quite possible they were burnt, which could eventually lead to tree death. The number and size of the roots has a direct influence on how quickly the tree declines.

Managing a lightning-struck tree

Here are a few guidelines with managing a tree recently struck by lightning:

• Has the tree split, causing it to separate partially or totally? If structural integrity has been compromised, then removal may be the only option

• Is there a deep crack in the main stem? Longitudinal cracks up the main stem, deeper than one third of the tree’s diameter, probably mean the lightning has entered the woody xylem tissue and caused extensive damage. Structural defects are highly likely. Assess targets and the consequences, remove the tree if high-value targets will be impacted.

• Is there a deep crack or cracks on sizeable branches?

If the cracks are one third or more the diameter of the branch, then carry out reduction pruning or remove the whole limb if possible

• More than one third of the tree’s bark was removed around the circumference of the trunk at any one point by the strike.

Bark has been stripped from around the trunk exposing the tree to potential decay. Monitor the tree for decline. Assess targets and consequences, remove if high-value targets will be impacted, and

• Less than one third of the tree’s bark is removed around the circumference of the trunk at any one point.

Monitor the tree for several weeks to assess the extent of the damage. Recommend follow-up maintenance treatments if required.

The above comes from Arnold Brodbeck, Jack Rowe, and Jim Jacobi at the Alabama extension website (aces. edu/blog/topics/forestry/caring-forlightning-struck-trees).

Expertise is needed

We are facing challenging times in managing our green canopy cover, especially in our harsh urban environment. Now, more than ever, we need to partner with local and state governments to offer our expertise and guidance on sustainable tree management policies and urban greening strategies.

YOU CAN’T JUDGE A TREE BY ITS COVER

Tree Radar Australia uses a ground penetrating Radar Unit to provide the only, completely non-invasive method of tree decay detection and tree root detection available in Australia.

TREE RADAR UNIT™ DECAY DETECTION.

Tree Decay is a severe problem which can put all the structure around a tree at risk. With Tree Radar Units™ decay detection, Tree Radar can scan for decay in any tree regardless of its height. The Tree Radar unit can give an accurate read out of the severity of decay in a tree without having to penetrate the Tree’s surface.

TREE RADAR UNIT™ TREE ROOT DETECTION.

Tree Radar Unit™ can detect and establish the root proliferation of a tree, this allows the arborist to inform developers of any structural or instability issues without the need for drilling or digging.

Guide to choosing the best attachment for forestry jobs

Running a forestry business is a challenging and rewarding endeavour. Forestry business owners need to secure continual access to lucrative woodlots, and they also need to invest in heavy timber equipment that cuts back on labor costs and maximises productivity. This guide to forestry equipment introduces the top attachments forestry businesses can invest in for success. It outlines the different forestry attachments and provides tips for choosing the right forestry attachment for your business. It also explains why choosing Cat® forestry attachments ensures the best value for your investment.

Acrucial consideration is which types of work tools you’ll need. With the right work tools, any standard heavy equipment can be taken and turned into a highly functional and versatile machine that takes on specific duties. Here are five of the best equipment attachments for a forestry businesses to invest in:

Log and lumber forks

Widely utilised for Cat wheel loaders in forestry applications, load and lumber forks attachments have been designed from the beginning to work exclusively with Cat machines.

Only Cat forks are built to precisely match the performance characteristics of Cat machines.

These forks come with a top clamp and with a pin-on or quickcoupler pick up. They offer the best productivity for loading and unloading logs or lumber on forestry sites and in processing plants.

Millyard Forks

Similar to log and lumber forks, Millyard forks also offer distinct quality and feature benefits which competitors can’t match –like a next-generation top-clamp design with superior strength and durability in mind. Cat top-clamp wrapper is made from a single, seamless piece of cut steel to minimise welding, increasing the strength and decreasing the likelihood of cracking.

Forestry grapples

Buckets

As one of the most versatile attachments in heavy equipment, bucket attachments are necessary for site clearing and cleanup. Use a bucket attachment throughout operations to clean up debris and clear access ways. An excavator bucket can also be used to dig around tree stumps to extract them for removal. Or, put the bucket attachment to use in a final cleanup pass, loading and hauling away unwanted brush or trees.

There is an extensive range of buckets available to attach to your heavy equipment, whether it’s an excavator or a loader. Cat generalpurpose, severe-duty and excavator buckets with thumbs all help to clean up with precision and efficiency.

Grapples are attachments designed to fit on forestry machines and make quick work of transporting trees. Their unique curved design means multiple trees can be gripped at one time, making them very efficient at relocating trees after they’ve been processed. Additionally, grapple attachments are used to load and unload logging trucks before and after their journey, making them useful in the forest and at the lumber’s destination.

Forestry mulchers

After trees have been harvested, their stumps may still remain. These can essentially make the land unusable. Luckily, forestry mulcher attachments are designed to tackle the problem of leftover tree stumps.

Forestry mulchers attach to forest machines and excavators and work by rotating a shaft containing many hardened steel teeth. With a combination of downward force from the forestry machine and the rotation of the mulcher shaft, the teeth are able to pulverise the remaining stump.

Forestry mulchers are so effective in destroying stumps that they can often remove the stump below the ground level. Afterward, the stump hole can be filled with dirt and smoothed over, leaving no trace of the stump.

Contact a Cat dealer

Businesses looking to invest in new forestry attachments need to source them from a reliable dealer. For more information about Cat forestry attachments, visit your local Cat dealer:

Forest Centre and Granite Tree Works

Forest Centre is the equipment supplier which not only meets the high standards and embraces the environmental aims of Granite Group Services, but gets actively involved in helping the company achieve its goals.

Granite Tree Works’ Westtech Woodcracker CS750 smart grapple saw is the first retrofitted to a Magni telehandler in Australia. Image: Westtech

Granite Group Services encompasses several divisions, one of which is Granite Tree Works, and Director Jon Rogash is strong on the company’s aims.

“Everything we remove, we recycle,” the Mornington Peninsula-based director told The Australian Arbor Age “Absolutely everything we can.”

“We don’t believe in waste, he continued. “We work very closely with a mill called The Wood Project and recycle as much timber as we possibly can.”

That’s saying something, because Jon and his team run a sizable collection of machinery which is kept steadily at work.

“It’s a pretty large fleet,” Jon outlined. “We have a Westtech Woodcracker CS750 smart grapple saw – the first Westttech grapple saw retro-fitted to a Magni telehandler in Australia – and we also have a Westtech Woodcracker W1350 log-splitting grapple that partners up with our Morbark 22x30inch chipper, so we don’t get stuck with log wood. We can break it down and we can feed it all through the chipper.”

Filling out this particular set, but by no means completing the fleet inventory, is a Hultdins SuperSaw 555 grapple saw unit retro-fitted to an existing rotating grapple, operating on a 14T excavator.

All three attachments came from Forest Centre.

Working hard

The work of Granite Tree Works is heavily based in land clearing and large-scale tree removal, although the company also offers earthworks, driveway packages, and complete packages to builders. A division of the company is also focussed on its environmental aims, and includes

a horizontal grinder, forestry mulching and similar machinery to ensure the product of the company’s activities can be reused and recycled.

Despite a considerable commitment to a sizable fleet of machinery, Granite Tree Works’ doesn’t include any LGAs or councils.

“We’re solely concentrated on the private sector,” said Jon, “and we’re booked out for the rest of the year.”

Playing favourites

We asked which machine was the most popular with the Granite Tree Works team.

“They’ve all got their different purposes,” Jon explained thoughtfully.

“I like the Magni for the control it has over the lifts. When we’re working in tight spaces, over structures and things like that, it’s very smooth, and the Woodcracker CS750 has incredible grab power, so it doesn’t feel like a load is going to go astray.

“That gets everything down to the height of 10 metres, and then the 14-tonner with the Hultdins takes over. It’s just so quick and efficient.”

Forest Centre

Why retro fit the attachments in the first place?

“I wanted to set up the 25-metre so it was actually light enough to transport ourselves on our tri-axle float, being 18.1 ton instead of 23 ton,” Jon told us, quietly gliding over what a daunting task that could possibly be.

As it turned out, Westtech grapples are designed to fit and work seamlessly with a wide range of machinery, and the fitting of the grapples wasn’t too much trouble. And that’s helped along by Granite Tree Works’ association with Rey Kell at Forest Centre in Tumut, NSW.

“100 per cent!” agreed the Victorian. “I don’t deal with anyone else for attachments. Everything goes through Rey at Forest Centre.”

We asked why that was.

“We think a lot alike,” said Jon. “Mechanically, I tell him an idea and he’ll go, ‘If we do it a bit different…’ or he’ll throw a couple of other ideas out there, and it makes the whole retro-fitting scenario so much easier. There’s never an issue. It’s always a result when it’s Rey and Forest Centre.

“I probably end up on the phone too long with him,” chuckled Jon, who clearly wasn’t complaining. It seems like sessions of problem solving with Rey at Forest Centre are one of the enjoyable parts of purchasing and fitting equipment.

And after speaking to Jon, it looks as though those conversations will be continuing for some time to come.

Isuzu’s legendary reliability and power allow the Piranha BT300 to make short work of even the toughest job.

Piranha Chippers and Isuzu

The Japanese engine giant gives factory backing to a new Australian arbor sensation.

Piranha chippers continually give high-performance and yield the highest return-on-investment figures, ultimately increasing bottom-line dollars. One of Piranha’s foremost suppliers is a leader in the world of diesel engines: Isuzu.

Clean running. Power packed

In 2016 Isuzu brought the 4HK1 –arguably the cleanest Japanese diesel engine – to the Australian market, and nearly a decade later there’s still nothing quite like it for advanced Japanese engine technology. It meets emission-control requirements for commercial vehicles laid out by the current Australian Design Rules (ADR) 80/03, exceeds Euro V, and complies with Japan’s Post New Long-Term (PNLT) emissions standard.

But being environmentally conscious doesn’t mean the Isuzu can’t still pack a serious punch. The 4HK1 engine is a low-displacement, high-torque, fourcylinder, turbocharged and intercooled diesel engine which produces a classleading 197hp. A hydraulic autoengaging clutch on the BT300 ensures the easiest start-up and operating procedure of any hand-fed chipper unit currently available, and Isuzu’s legendary reliability and power allow the Piranha BT300 to make short work of even the toughest job.

Makes sense

With Isuzu being such a popular brand in commercial vehicles, especially among arborists, it makes a lot of economic sense to run an Isuzu diesel in an Australian designed and built chipper. It means a single set of service items like filters and belts can be kept on hand to cover both the work vehicle and the Piranha.

Isuzu’s reputation for reliability, superb engineering and after-sales support is legendary and undeniable. When a company the stature Isuzu Australia gives its support to the Piranha Chippers brand, it makes a big statement about the performance and durability of the Australian chipper.

Piranha Chippers’ BT300 is powered by the 4HK Isuzu turbo-diesel, a low-displacement, high-torque, fourcylinder, two-stage turbocharged and intercooled diesel engine.

Contact the Piranha team today. They’re very keen to show just how good the BT300and its Isuzu diesel are. Call 1300 406 171, or log on to piranhachippers.com.au. It makes a lot of economic sense to run an Isuzu diesel in an Australian designed and built chipper

Green jobs are booming

Through its Certificate III in Conservation and Ecosystem Management, TAFE NSW is arming students with the practical experience and specialist skills to give them an advantage in the booming ‘green’ jobs market.

Tomas Pool chose TAFE to gain more hands-on skills and is now focussed on regenerating land to its natural state.

Image: TAFE NSW

Current TAFE NSW Taree student, Tomas Pool, is already working in the field, employed as a bush regenerator for Natural Resources Group.

“I’ve always had a passion for the environment and outdoors,” he said. “I grew up in the bush as part of a very green family in a house that was completely solar powered, and my mum worked in horticulture. I got to know plants and see how they grow. Plants are the primary producers, and they can be overwhelming, but there’s so much to learn.

“I studied ecology at university and have experience in botany, zoology, and even avocado farming, but I wanted to add to my passion, so I chose TAFE NSW to get more hands-on skills. This added to my knowledge and skillset which really helped with finding local work.

“My current role is focused on regenerating the land to its natural state by encouraging regrowth of the native habitat through removal of threatening weeds like lantana. We aim to limit

chemical usage and do most of this by hand, so the practical skills I gained at TAFE NSW really helped.

“Through TAFE NSW, I learned about cultural methods around land management, and at Natural Resources Group we work hand in hand with the Local Aboriginal Land Council and Tide Rangers. This is an area where I’d like to get even more experience, as well as focus on the scientific side of ecosystem management,” Tomas said.

Landcare NSW

Group Coordinator of Manning Landcare Group, Lyn Booth, has encouraged more local students to undertake Conservation and Ecosystem Management studies with TAFE NSW.

“The Manning region is facing issues including landscape degradation, soil erosion, soil health issues, and changing climate, which brings greater risks and more extremes that affect animal health, among other things. Manning Landcare is focussed on planting

riverbanks, regenerative farming techniques, and supporting land holders to learn new skills in managing their own land.

“We need more people on the ground and TAFE NSW is giving students the knowledge and hands-on experience to make a big difference,” Ms Booth said.

Get involved

Both Tomas and Lyn have encouraged people interested in making a difference to get involved through volunteering.

“It’s easy to get out there and get involved,” Tomas said. “Connecting with local groups is a good way to get known, broaden your knowledge, or find work. Get adventurous and explore, have some fun, and get to know your local environment through citizen’s science. If you want to turn your passion into a career, TAFE NSW is the best place to start.”

Husqvarna’s 525iDEPS pole saw delivers an extra measure of safety for skilled line workers, utility workers, and tree-care professionals.

Husqvarna 525iDEPS MADSAW

A new standard in professional pole saws.

The Husqvarna 525iDEPS MADSAW

is the industry’s first and only dielectric battery-powered pole saw individually tested to meet OSHA 1910.269 and Australian local compliance is tested to standard AS5804.3. Husqvarna performs local wet and dry high-voltage testing as an extra step to meet government, council and industry operational criteria.

The MADSAW 525iDEPS delivers an extra measure of safety for skilled line workers, utility workers, and tree-care professionals. It can be used in the bucket, in the tree, or on the ground for extreme versatility. Purposeful design allows the pole saw’s sections to quickly disconnect for secure storage in a tree-care truck or utility vehicle, and it’s more productive than a manual saw while remaining as powerful as a hydraulic pole saw.

The battery-powered MADSAW makes pruning and limbing projects more efficient than ever before.

Low carbon emissions

With the MADSAW users can be confident it produces lower carbon emissions during active use than a traditional petrol product. The batterydriven MADSAW does not emit any CO₂ during use, while still providing the power and quality expected from a Husqvarna product. However, it’s important to note CO₂ emissions are generated during other stages of the product’s lifecycle, such as production, charging and end-of-life disposal.

Setting a new standard

Husqvarna’s 525iDEPS MADSAW has clearly set a new standard in pole saws for the arbor industry. It’s ergonomically designed and adjustable components are tailored to aid in reducing user fatigue, it’s incredibly versatile, and includes both 2.75m and 3.8m equipment as standard.

It even quickly and easily disassembles for easy storage and transport.

AirSpade

AirSpading is safe to the tree’s roots and a highly efficient method of performing exploratory excavations to locate existing roots and utilities. Images: Knight Pneumatics

With proper, professional, site management, there are a few areas where pneumatic soil excavation with an AirSpade can be extremely effective for the professional arboriculturalist.

Air Tilling

Trees and shrubs suffering from shallow soil compaction – typically due to pedestrian use or vibrations caused by vehicular traffic – or lacking vigorous root growth due to poor topsoil quality, are ideal candidates for air tilling.

Since most of a tree’s roots proliferate near the surface where they have the best access to oxygen and nutrients, air tilling is excellent at promoting robust and uniform root growth. If it’s necessary to affect soil to a depth greater than 15cm-20cm, it’s possible to combine air tilling with other methods such as radial trenching or vertical mulching.

While the tree-health benefits of air tilling alone (decompaction and aeration) are significant, this method is often used for soil augmentation as well.

Radial trenching

Radial trenching with an AirSpade is done to modify soil composition, improve aeration, and encourage root growth to moderate depths, typically 25cm to 30cm or more, and is especially effective when trees have highly stratified or shallow depth of viable soil or anaerobic conditions. Additionally, this application can be useful in planting areas where minimal disturbance is desired.

Vertical mulching

Vertical mulching with an AirSpade is done to de-compact and augment soil deep into the tree root zone.

This application is especially useful in areas with poor drainage, with shallow or impervious soils, or shared by perennial or ground-cover plantings where minimal disturbance is desired.

Aeration and soil amendments from vertical mulching can encourage roots to grow deep into the soil profile, improving the tree’s stability and the volume of viable growing medium.

Because vertical mulching affects the deepest soil profile, it is recommended for sites with shallow soil depth, hard-pan, anaerobic conditions, or other types of poor growing soils.

Root collar excavation

Trees commonly suffer when the grade is set too high against their root flare or root collar. This can occur when trees are planted at the wrong elevation or when trees subside due to improper compaction below the root ball when they are planted. Alternatively, root collars can be buried over time due to the accumulation of mulch or soil around the tree. Whatever the cause, harm to the tree from grade set above the root collar can be long lasting and should be remediated through root collar excavation (RCX) with an AirSpade.

Symptoms of this condition include:

• Rot or infection of bark at the base of the trunk

• Growth of roots that are too high relative to the natural root flare, and

• Girdling roots, which constrict the root flare and tree trunk.

Girdling can also occur on urban sites where roots have limited room to grow or have encountered compacted or anaerobic soil conditions. Use of an AirSpade allows tree root collars and girdling roots to be excavated with minimal damage to the tree. Once uncovered, a certified arborist can easily identify roots that need to be removed or trained.

Root pruning

AirSpading is safe to the tree’s roots and a highly efficient method to perform exploratory excavation to locate existing roots and utilities. Almost any site-work operations –including the building of foundations, pavements, drainage infrastructure, and utilities – present ideal opportunities for AirSpading and root pruning.

Proper root pruning will encourage future growth and

minimise negative impacts to structures or utilities.

Once the existing roots have been excavated, a certified arborist can easily determine the best places to make clean cuts using a hand pruner.

Bare rooting and transplanting

Bare rooting with an AirSpade can be applied to perennial, shrub, and groundcover plantings.

This is a preferred method of transplanting because of its efficiency and ability to preserve fine root systems. Furthermore, bare rooting small plants is often required during more extensive root-zone treatments such as aeration and decompaction or other site-work applications. Use of an AirSpade can significantly reduce trauma to the tree.

Urban tree soil replacement

It may be desirable to partially replace the soil around a tree’s root zone in an effort to enhance the tree’s health and lifespan.

This application is ideal for tree plantings with root zones extending underneath pavement and those that have poorly suited or limited soil volume, or where pavement is proposed to be added or replaced within an existing root zone. Similarly, this may be applied to trees planted in high-use lawn areas (for example within parks or campus landscapes,) where soil replacement is desired to improve lawn durability and health.

While flat-out buying a new machine every few years isn’t always an option for contractors, leasing can make upgrades a reality.

The lease you can do

Get the equipment you need when you need it with flexible leases from Brandt.

In arboriculture and construction, working seasons are short and hours are long. Efficient, reliable machines minimise costly downtime. That means staying on top of maintenance costs and investing in the latest technology. While flat-out buying a new machine every few years isn’t always an option for arborists and contractors, leasing can make those upgrades a reality. And Brandt offers a variety of flexible lease options to help you break new ground in your operation.

Benefits

Leasing delivers many benefits, including lower upfront costs, flexible payments, no asset depreciation, and much more. It makes new equipment more accessible to businesses with limited capital, preserves capital so it can be invested in other areas of your business, and helps manage cashflow better.

Plus, lease payments are often tax deductible, providing additional savings.

Brandt makes leasing painless. Brand new John Deere equipment is available at the lowest rates in the business, and customers:

• Pay less on the machine with flexible lease contracts and rates

• Choose between returning a machine at maturity, buying it, or refinancing it

• Structure a plan around your business needs, like matching payments to cash flow and more, and

• Add fuel and go—the machine, warranty, and maintenance are all included.

Flexibility

A standout feature of Brandt leases is the opportunity to lease equipment for three years with flexible terms. If your operation demands more hours in peak

seasons and fewer in the off-season, Brandt has you covered. This flexibility ensures you don’t pay for more than you need, making it a cost-effective option.

As mentioned above, comprehensive warranty and full maintenance are included throughout the term of the lease. This minimises any potential downtime due to mechanical issues, keeping your operation running smoothly. The peace of mind that comes with knowing your equipment is in top working condition is invaluable, especially during critical farming or construction periods. So, you can focus on your work without worrying about the potential high costs of repairs or replacements.

At the end of the lease period, the benefits continue. You have the choice to return the leased equipment and switch to a brand-new model. This eliminates the financial burden and

Shakanda: anything a customer needs

Shakanda’s custom-built Chipper Tippers and truck fitouts follow a proven and well-established process.

Victorian-based truck-body builder, Shakanda, specialises in custom designing and building just about anything for any truck or working vehicle, but its Chipper Tippers are a specialty.

Shakanda bodies feature a threeyear structural warranty, a fully sandblasted, 2-pack, zinc-primed and 2-pack top-coated finish, and a stack of extras are available – pretty much whatever the customer can imagine. Producing bodies for specific tasks which meet the truck-manufacturers’

specs is Shakanda’s bread and butter.

As Shakanda’s Body Building Manager and Head of Engineering, Tim Knight outlined, “You could pick any make and model you could possibly want. We can custom design a chipper bin, or pretty much anything a customer needs, and make sure it has the maximum payload possible without exceeding the truck’s GVM or axle capacities. We give as many estimations and as much information as we can to the customer so they can make informed decisions.”

A careful process

The process for a custom build is not as complex as it may first seem, thanks largely to Shakanda’s proven system and use of advanced technology.

“A customer will come to us and say which make or model of truck they have, and what features they’d like the final build to have,” Tim explained. “Once we have that clear we will complete a 2D (two-dimensional) layout drawing.

“It’s a preliminary drawing, which has weight calculations and estimations,

The finished product: a custom designed and built chipper bin which doesn’t exceed the truck’s GVM or weight capabilities. Images: Shakanda

The finest quality Chipper Tipper bodies for all parts of the country “ ”

and it gives the customer the chance to look at the actual truck and what they’re having fitted to it. The drawing tells them what their payload is going to be and gives an estimation of frontaxle and rear-axle weights on the fully loaded vehicle. This ensures they get the capacity they need without exceeding any regulatory limits.

“This is accompanied by a quote based off the 2D drawing, and usually has a list of other optional items that could be added to their build.”

“That’s the first stage.”

Getting serious

Once the customer has had time to check through the drawing and ensure everything is as they imagined and requested, and the quote is accepted, the next step is for Shakanda to schedule the build into its system, then

engineering starts modelling up the specs using Solidworks. This is when the 3D (three-dimensional) Model is created. From the 3D model all the work instructions and drawings for the build are done so the vehicle body can be manufactured.

A three-dimensional drawing lets the customer see what they’re getting before the build begins.

A two-dimensional layout drawing shows the customer an estimation of what their payload’s going to be, and their front-axle and rear-axle weights on a fully loaded vehicle.

Eye on the industry

Tim continued.

“The 3D modelling is based off the 2D initial drawing, and it’s for fabrication, but we also get the customer involved at this stage.

“Even though they’ve signed off on their two-dimensional drawing, it’s always better to have a look at a threedimensional model. It’s more intuitive for a customer if they can visualise the whole vehicle and its features in 3D. The customer can see and look over their vehicle. If the customer can’t meet in person, we can do this over Teams, Zoom, Google Meet or something like that, and wherever they are – on their phone, tablet, in their office, wherever – they can see the model.

“We share the model live. We go over all aspects of the build and show them everything. At this stage the customer might decide to make changes or may

be happy with our design and we will move to the next stage.”

Full custom

The precision and procedure used in planning a Shakanda job is a reflection of the care and attention to detail which goes into the build itself. Ensuring the customer’s vision is being made reality is at the heart of custom work, and ensuring the safety and durability of the work itself is at the heart of Shakanda’s philosophy.

Tim summed things up: “At Shakanda, we value feedback from both industry professionals and end users, whether positive or negative. This input helps us continually enhance our chipper bin products, ensuring they meet the daily needs of our clients.”

Ways to ensure your business does not stumble, trip and fall

–

Every business has an exposure to slips, trips and falls. Make sure potential claimants are approached at the time of the fall. Image: sittinan/stock.adobe.com

Whether you have a restaurant, a shop, an office, working at a site or work from home – if a customer is on your premises, generally you’re responsible for their safety.

A trip here or a fall there could mean a claim is headed your way. Every business has an exposure to them, even home businesses.

Here are few steps to minimise the impact it can have on your business:

1. Make your site safe

2. Record your actions

3. Approach the potential claimant

4. Record the incident.

Insure against costs

The reality is, slips and trips are common and the consequences can be significant.

There are two issues – there’s the compensation and the legal costs of defence and there can be a very large amount of money involved in both. Having an appropriate public liability insurance policy in place can help your business meet these costs.

Equipment logging jobsite efficiency

Powerful equipment goes a long way to completing jobs on time and within budget, but combining wood-processing power with smart technology can actually cut job times by boosting onsite productivity.

Among the machinery that has increased in sophistication, Vermeer tree-care equipment has evolved to include exclusive features that promote ease of operation, efficiency and operator safety.

Not only does using innovative machinery that embraces modern technology boost contractor efficiency and productivity, it demonstrates to customers and prospects that they’re ahead of the curve and staying abreast of the latest industry offerings.

When it comes to projects involving timber processing and wood chipping, powerful machinery talks, but

contractors looking to put their best foot forward for these jobs should deploy equipment that offers state-of-the-art features.

It’s no longer enough for contractors to have chipper equipment that’s tough and durable – the machinery needs to be smarter and more advanced.

Combining power with smart features

Proving that mighty machinery doesn’t have to come at a cost to innovation, Vermeer’s BC2100XL Chipper delivers extreme power for boosted jobsite productivity, coupled with the innovative

features that will streamline operations and deliver projects on time.

Helping cement the BC2100XL’s power superiority, the two horizontal feed rollers offer 4536kg of combined pulling force.

With the BC2100XL’s exclusive SmartCrush feature, the days of equipment standing idle while operators trim tree branches are long gone. The aptly named system offers increased down pressure on material being fed, tackling branched materials without breaking a sweat.

The intelligent SmartCrush system automatically increases pressure once the upper feed roller freely raises for four seconds, meaning the upper feed roller can easily climb on top of large, forked material before the increased down pressure is applied for the maximum pulling force.

Further backing the BC2100XL’s technological credentials and increasing operator productivity, the patented SmartFeed control system monitors rpm and senses jams, automatically stopping or reversing the rollers as needed or when feeding in larger hardwood material.

Underscoring Vermeer’s commitment to boosting operator productivity, the BC2100XL Chipper offers an optional remote control which allows contractors to operate one machine to load while still maintaining control of the chipper. The optional winch attachment can handle material up to 1815kg and mitigates the need for operators to drag material to the chipper.

The BC2100XL is backed by Vermeer’s one-year/1000-hour limited warranty and three-year/3000-hour extended limited warranty on drum housings,

Ficus, a rare genus: part 2

Cassian Humphreys follows up from his thoughts in the December/January 2024 issue: ficus offers a unique opportunity for land care.

Since 2021, and after a number of publications on fig trees, I still find my attention on the genus ficus.

In 2022, I, as part of a small team from the Tree Climbers Brotherhood carried out three advanced arboricultural assessments on ancient fig trees. The study included associate understorey and epiphytic plants, though perhaps the most notable plants observed were up to five different species of other young fig trees growing as stranglers.

These past studies were fully recorded in The Australian Arbor Age under the titles The Body Language of an Ancient Sentinel parts 1 and 2 in the Dec/Jan 2021 and April/May 2022 issues. Though I have had a career working on fig trees and observing the genus growing as stranglers on a range of gum trees, I had not seen ficus species growing on Ficus before.

I’ve been planning this article for over a decade, although I was waiting

prelude to Part 1 involved a past client and the managers of a Brisbane tree company I have long had connections to – Evergreen Tree Care.

Support and nurture

Ficus installation projects have been close to my heart for two decades, although finding clients to support proactive arboriculture is not always easy.

Technical feature

Nature always sets the precedent for we humans, and the growth of Ficus as stranglers spans Queensland and NSW. A past-colleague of mine some years ago predicted arboriculture of the future would become speciesspecific, specalised to the species of given bio-regions. I can see that this is true of Ficus for much of the central coast and north-east coast of Australia. The capacity for the species of this genus to propagate and generate over

existing bodies from buildings to other trees is unique and highly significant. We have no other genera as capable of such feats. As discussed in Part 1, the capacity for the genus to form natural grafts and aerial prop-roots directs us to use the nature of the species to outgrow its own structural limitations. By inducing graft-unions between bifurcations, props on elongated limbs and around decay pockets and columns, we can enable such trees to

lay down sufficient wood to outgrow structural constraint, dysfunction and even disease. With Phellinus noxius or Kretzschmaria deusta being common in citified environments we owe it to the fig trees to support them to outgrow their limits – especially when doing so saves money with enduring environmental benefits. Ficus regularly grow aerialroots in association with storm-damage, assisting transition from epicormic to endocormic crown-structure.

Figures 2 and 3: Kretzschmaria deusta in a recently felled stump of Weeping Fig, likewise in Roma Street Parklands. This was a forest specimen surrounded by other trees, pictured soon before felling while getting data for Part 1 of this article. Field pasture trees subject to greater wind load tend to grow much larger buttresses. The red arrows indicate prop-root generation in support of the woody footprint. It’s interesting to observe the lack of inclusion only centimetres below the cluster of V forks.

Walls

Ficus is known for having a strong Wall 4 – or ‘barrier zone’ to quote Shigo. This the zone which separates new wood from old, and a study of the distinct outer boundary between the creamy healthy wood and the discolored and decaying wood in Figure 2 supports this. This genus, however, has weaker walls 1 to 3, or resistance-zones, hence the spread of dysfunction up down and across the grain within the barrier zone. Professor Claus Mattheck’s early reference to the 70/30 rule – 70% sound-wood to 30% decayed wood – as a reference to tree retention has fueled decades of mis-thinking by arborists,

many of which still see any less than 30% wall thickness as being the criteria for tree removal. In light of experience with post tree-risk management systems such as QTRA and VALID, many tree-managers globally have redefined that model to 90/10. In the case of Figure 2, healthy wood buttressing in proportion to the decay map, we have 75/25 or 75% decay verses 25% soundwood. Decay which abuts outer-bark between buttresses is a lesser concern, especially when a fig tree lays down aerial-roots outside of that (refer to the red-arrows in Figure 2).

Between such healthy buttressing and the inducement of the prop root I would

say this tree with Brittle cinder fungus (Kretzschmaria deusta) was engineered well enough to stand for decades. The tree had already grown an aerial root over a face of diminished wall thickness by its own prompting. I documented the same evidence of aerial-root optimisation in association with Ficus benjamina and Phellinus noxious in the 2012 AAA article Lest We Neglect

Salute

Imagine if inducing aerial-prop roots to assist fig trees to gain woody ground was mainstream teaching. Such work, along with soil decompaction, mulching and revegetation and Trichoderma

At the time of data collection on Part 1 of this publication I had the joy to appraise this fig tree in Roma Street Parkland, a Moreton Bay Fig with major columnar cavitation following leader failure. Under their own initiative staff had installed a replacement strangler fig to help stabilise the decaying host tree in the long term, with aerial roots into the cavity and into the external pipe pictured. The goal was rapid root acceleration.

inoculation (to help counter aggressive fungi), is, I hope, the future of arboriculture.

The use of round-ended chisels combined with hormonal treatment, as well as sphagnum-moss patching to facilitate graft and aerial-prop-root formation, is likewise arboriculture true to its definition.

Based on discussion posed in this series of articles we have the perfect recipe for sustainable tree management in subtropical and tropical bioregions of Australia and beyond. To my old friend who foresaw the future of arboriculture being driven by bio-region and species, I salute you.

Fast action and a good result I have a great appreciation of the horticultural works being employed in Roma Street Parkland.

The horticultural strategies of assisted-prop inducement pictured in Part 1 have long needed to be included in the arboricultural repertoire. This, including graft inducement, is a practice of mine going back to my first sphagnum-moss patch on a vandalized Weeping Fig in a Keperra park, Brisbane, in 1995. This was following a lower limb being torn out, leaving a branch breakout injury and a nasty trunk-tear on a tree I had planted myself. The injury I treated via abrading the periphery of the tear with steel wool, dusting the surface with root-hormone powder (I use top-

grade honey now), before plugging the injury with sphagnum moss and binding it with grafting tape. This I learnt to do as a horticultural student in the mid 1980s. Within five weeks the 4cm by 15cm injury site and trunk hole were completely covered by fine aerial roots. Three months later I removed the tape, then another few weeks later I returned to observe the aerial roots desiccated. When I rubbed them vigorously by hand they sloughed off to reveal the wound completely closed by wound wood. What would have taken between three and five years to close left to its own devices was occluded in less than five months.

The capacity for the species of this genus to propagate and generate over existing bodies from buildings to other trees is unique and highly significant “ ”

Figures 5 and 6: Images of Ficus installations on the dying Moreton Bay Fig shown in Figure 1. I championed this project in association with Evergreen Tree Care based on earlier projects of my own. With Evergreen arborists we installed two fig trees: one in the upper crown and one in the mid crown.

Natural progression

Following my getting involved with consulting and report-writing projects with long-serving associates Henk Morgans and Nick Smith, I coincidentally realised their company – Evergreen Tree Care – was the preferred contractor to Roma Street Parkland.

With like minds coming together in association with leading Roma-Street Horticulturist Robert Paksec, our first Ficus installation project was supported into creation. We now have a camphor laurel Ficus installation to do.

Initially we established an advanced grown Green leaf Moreton Bay fig (F. watkinsiana) via cage and coir burlaps into a wide fork 10m up the tree (refer to Figures 5-7). Then we ran a slotted 100mm cellulose/compost/probiotic

filled Agline pipe with irrigation line running from ground to the base of the basket, returning to install another pipe running 20m up the tree with a Weeping Fig in a 1.5m compost-filled sock of hessian. All installed by climbers, the pipes were filled at ground-level and hydrated/ activated by immersion in the parkland dam.

The tail of the second pipe was fixed to the ground, providing irrigation to a weeping fig already at ground level. We found a further three native small-leaved figs, (F. obliqua) growing on and in buttress roots. Nature was already showing us the way.

Eye on the future

With the desire to use non-plastic

resources I am keen to see the use of coir tubing instead of Agline, the trick being to find a manufacturer to create that. I also recognise the need at intervals along the Agline pipe to make holes, and to tie hessian-bands to help encourage the generation of lateral strangler-roots to help engulf the trunk (we are already booked in to return and do that in July).

The next step with this tree-cultural operation is to promote it to creekland weed-tree managers, to awaken them to the opportunity to use Ficus for such projects. The current practice of removing weed trees, destabilising creek banks, is a very poor strategy.

With Queensland, northern-NSW and sustainable land care in mind, praise be to Ficus and the future of sustainable arboricultural initiatives.
