If you ask ten people what an arborist does, a fair few will say, “Cuts trees down,” or “Trims branches.” That is part of the work, sure, but it is only part of the picture. An arborist is there to look at the whole tree, the whole site, and the whole risk. We are not just looking at what is hanging over the fence or brushing the roof. We are looking at structure, health, weight, access, species, age, defects, nearby targets, and what is likely to happen after the next decent blow comes through Perth.
After more than two decades in the industry, I can tell you this much: trees have a long memory, and bad work catches up with them. A rough job done in half an hour can create a problem that costs a homeowner thousands a few years later. On the flip side, the right prune at the right time can keep a good tree safe, healthy, and useful for years. That is the difference a proper arborist brings.
In this guide, I will walk through what an arborist actually does, how the job differs from tree lopping or landscaping, when you need one, and why it pays to get the work done properly the first time. Around Perth, where we deal with hot dry summers, winter storms, sandy soils, tight suburban blocks, and plenty of fast-growing gums and palms, that experience matters.
What an Arborist Actually Does Day to Day
An Arborist Works On The Whole Tree, Not Just The Obvious Problem
A proper arborist is trained to understand trees as living structures. That means we do not just look at the branch over the driveway and call it a day. We look at how that branch connects to the rest of the canopy, whether the tree is under stress, whether there is dead wood higher up, whether the trunk has defects, whether the root zone has been disturbed, and what sits underneath if the tree sheds a limb.
Some days that means pruning. Some days it means diagnosing decline. Some days it means giving a client the news they did not want but probably suspected already: the tree is not worth throwing good money at.
A lot of jobs start with a simple concern. “This branch is leaning over the patio.” “The gum is dropping limbs.” “The palm is full of dead fronds.” “The stump is in the way of the new paving.” On the face of it, those sound straightforward. But trees are a bit like old houses. Once you know where to look, you often find the real story behind the surface problem.
The Work Is Part Science, Part Physical Skill, And Part Judgement
Arboriculture is not just labour. It is hands-on work, no doubt about it, but good judgement is what separates a tidy job from a proper one.
An arborist needs to understand:
- how trees grow and respond to pruning
- how weight is carried through the canopy
- what signs point to disease, decay, or structural weakness
- how to dismantle timber safely near homes, fences, sheds, and power lines
- when a tree can be retained and when removal is the safer call
That balance matters. At Tree Amigos, the approach has always been simple enough: treat the tree with respect, tell the client plainly what is going on, and do the job safely. That applies whether it is a backyard prune in Duncraig or a more technical removal in a tight access site with walls, roofs, and neighbouring structures all crowding the drop zone.
Arborist, Tree Lopper, or Landscaper? Here Is the Difference
Why Tree Lopping Gets People Into Trouble
This is where a lot of people get caught. They assume anyone with a chainsaw and a ute can handle a tree job. That is how problems start.
Tree lopping is the rough, indiscriminate cutting of major parts of a tree without regard for structure, species, health, or long-term safety. It often leaves big wounds, ugly stubs, and a stressed tree that responds with weak regrowth. It may look like a quick fix, but it usually kicks the can down the road.
We have seen plenty of Perth trees that were butchered years earlier. The owner thought they were doing the sensible thing at the time. Then the regrowth shot out like fireworks, the attachment points stayed weak, and after a couple of summers and one hard winter front, the whole thing turned into a liability.
“A rough chop now can become a dangerous headache later.”
That is not scare talk. It is just what happens when poor pruning creates poor structure.
What An Arborist Does Differently
An arborist prunes with purpose. Every cut should achieve something useful. It might be deadwood removal, weight reduction, canopy lifting over a driveway, clearance from a roofline, or remedial work on a tree that was previously handled badly.
We also know that different species react differently. A mature gum on a suburban block does not respond the same way as a palm or an ornamental tree in a front garden. Timing, extent, and placement of cuts all matter.
That is why qualified arborist input is so important. Tree Amigos makes a point of having a qualified arborist on site for every job, because this is not guesswork and it should not be treated like it is.
Where Landscapers Fit In
Landscapers have their place. They are the right people for lawns, irrigation, garden beds, mulching, soft landscaping, and smaller shrubs. But once you are dealing with large trees, structural pruning, hazardous limbs, removals near buildings, stump grinding, or work around power lines, you are in arborist territory.
A realistic example? A homeowner might ring a gardener to trim a large gum over the shed. The gardener turns up, looks up, and realises the limb is too heavy, the access is tight, and the work would need proper rigging to avoid damaging the roof. That is not a knock on the gardener. It is just a different trade.
The Main Services an Arborist Provides
Tree Pruning For Health, Safety, And Clearance
Pruning is one of the most common arborist jobs, and also one of the most misunderstood. Good pruning is not about hacking the tree back until it looks smaller. It is about improving structure, reducing risk, and managing space sensibly.
Common pruning work includes:
- removing dead, dying, or diseased limbs
- lifting the canopy for vehicles, pedestrians, or sightlines
- reducing weight on overextended branches
- clearing away from roofs, fences, and service lines
- improving balance after storm damage or previous bad pruning
In Perth, we often see branches rubbing on tiled roofs, limbs pushing into fence lines, or low canopies blocking access to caravans, trailers, and work vehicles. A light, well-considered prune can sort that without hammering the tree.
The trick is knowing how much to remove and where. Cut too much, or cut badly, and you stress the tree. Leave too much, and the risk remains.
Tree Removal When Keeping The Tree Is No Longer Sensible
No decent arborist comes at every job itching to remove the tree. But sometimes removal is the sensible call.
A tree may need removal if it is:
- dead or dying beyond recovery
- structurally unsafe
- severely diseased
- lifting or undermining surrounding structures
- poorly located for its size and species
- damaged beyond repair after a storm
Large removals are where skill and planning really show. In a perfect world, every tree would have open ground all around it. In the real world, it is usually jammed beside a patio, garage, pool fence, retaining wall, or neighbour’s roof.
That means dismantling in sections, setting rigging points, controlling swing, and lowering timber carefully. Some jobs need cranes. Some need elevated work platforms. Some need a climber to work through the canopy piece by piece while the ground crew manages ropes, debris, and site safety below. Tree Amigos has extensive experience with large dismantling work, including crane and EWP removals in constrained environments, and that sort of experience is what keeps high-risk jobs from going pear-shaped.
Stump Grinding And Site Clean-Up
Once the tree is down, the stump is often the next nuisance. It gets in the way of paving, landscaping, and replanting. It can be a trip hazard, and on some species it will keep trying to regrow.
That is where stump grinding comes in. The stump is ground down below ground level so the area can be reused properly. Small access machines suit tight side paths, while larger grinders handle the bigger, stubborn stumps in more open sites.
A decent arborist also leaves the place in good order. Nobody wants the tree gone but the site looking like a bomb hit it.
Health Checks And Tree Inspections
A lot of what we do starts before a saw even leaves the truck. Clients want to know whether the tree is safe, whether it is worth saving, and what sort of work is actually needed.
A tree inspection can include looking for:
- deadwood in the canopy
- cracks and weak branch unions
- fungal bodies near the base
- trunk cavities or decay
- lean and root plate movement
- signs of stress after heat or storm damage
- previous poor pruning
- pest activity or disease symptoms
Sometimes the answer is straightforward. Sometimes it takes experience to tell the difference between a tree that looks rough but is manageable and one that is quietly failing.
Emergency Tree Work After Storms
Emergency work is where calm heads count. After a storm, the site is often messy, tense, and unpredictable. Trees can be split, hung up, partially failed, or loaded under tension. That is not the time for cowboys.
We provide emergency arboricultural services because when a limb is on the roof or a tree is blocking access, people need the site made safe promptly and properly. The first goal is stability and safety. The second is clearance. The third is working out what can be retained and what needs to go. Tree Amigos offers 24/7 services, which reflects the reality that storm damage does not wait for business hours.
How Arborists Work Safely at Height
Climbing, Rigging, And Elevated Work Platforms
From the outside, tree climbing can look a bit like controlled madness. A bloke up a tree with ropes and a chainsaw. But there is a system to it, and it has to be right.
Arborists use:
- climbing harnesses
- specialised ropes and rigging gear
- lowering devices
- friction management systems
- chainsaw strops and PPE
- elevated work platforms where the site allows
Every choice depends on the tree, the site, and the task. A broad, awkward gum over a house may need a climber and careful piece-by-piece dismantling. A safer access line might allow an insulated EWP if power lines are nearby. Tree Amigos operates a range of EWPs, including insulated variants for low and high voltage situations, which is the sort of equipment capability that matters on more complex jobs.
Why Qualifications And Insurance Matter
There is no room for bluffing in tree work. You are dealing with height, sharp tools, suspended loads, and often valuable property directly underneath.
That is why qualifications, safe systems, and insurance matter. Tree Amigos highlights arboriculture qualifications, EWP licences, power line certifications, first aid training, and $20 million public liability cover, and those are not throwaway badges. They are part of doing the work responsibly.
What Qualifications Should an Arborist Have in Australia?
Certificate Iii And Higher-Level Arborist Training
In Australia, a Certificate III in Arboriculture is generally the core trade qualification. That is the level most people mean when they say “qualified arborist”. It covers practical tree work, climbing, pruning, removals, equipment, and safety.
Higher-level qualifications, including diploma-level study, are more closely tied to consulting, diagnostics, reporting, and advanced assessment work.
At Tree Amigos, team training and certification are matched to role and job type, which is exactly how it should be. Some jobs also need specific tickets or competencies, such as:
- EWP operation
- medium rigid truck licence
- low voltage or high voltage clearance competencies
- first aid
- white card site compliance
Questions Worth Asking Before You Book Anyone
Here is a quick checklist worth using before you commit:
- Are you a qualified arborist?
- Are you fully insured?
- Will a qualified arborist be on site?
- What exactly are you recommending, and why?
- Do I need to check council requirements?
- Will I get a written quote?
- How will you protect nearby structures and access points?
- What is included in the clean-up?
Straight answers matter. If the quote feels vague from the start, the job usually goes the same way.
When You Need an Arborist Report or Council Approval
Common Situations Where Reports Come Into Play
Not every tree job needs a formal report, but some certainly do. Around Perth, that can involve:
- development or subdivision work
- boundary disputes
- verge trees
- suspected hazardous trees
- works near protected trees
- major pruning or removals that may need council consideration
If you are planning to build, extend, or make changes near established trees, it is often better to sort out the arborist side early. Leaving it until the last minute can gum up the works.
What An Arborist Report Is Used For
An arborist report sets out the condition of the tree, the observed defects or strengths, the risk level, and the recommended action. It helps councils, owners, builders, and managers make decisions based on evidence rather than guesswork.
On larger commercial or government sites, arborists often work alongside planners, builders, and site managers so tree protection, access, removals, and compliance are handled properly. Tree Amigos works across residential, commercial, industrial, and government sectors, which reflects how broad this work can be.
Signs You Should Call an Arborist
Warning Signs People Should Not Ignore
Some tree issues are obvious. Others are easy to shrug off until they become a real problem. Call an arborist if you notice:
- dead limbs over the house, driveway, or patio
- cracks where major branches join
- a sudden lean
- mushrooms or fungal growth near the base
- roots lifting paving
- repeated limb drop in summer or after wind
- branches tangled near service lines
- a tree that was lopped in the past and is now regrowing badly
A Realistic Perth Example
Say you live in an older suburb with a mature gum near the driveway. Through summer, it drops bark and a few small sticks. Nothing dramatic. Then after a run of hot weather, you notice more dead tips in the canopy. You still leave it. Fair enough. Life gets busy.
Then the first proper winter front comes through. A decent-sized dead limb drops and lands next to the car. Suddenly it gets your attention.
We have seen that kind of sequence more than once. In many cases, the tree does not need removal, but it does need deadwood removal and weight reduction before the next big wind event. Better to sort it now than pick bits of branch out of the guttering later.
Why Hiring a Proper Arborist Can Save You Money
Preventive Work Is Usually Cheaper Than Emergency Work
Good arborist work is not just about safety. It is about avoiding bigger costs.
Professional pruning can:
- reduce the chance of storm damage
- help identify problems early
- extend the useful life of a good tree
- avoid damage to roofs, paving, fences, and vehicles
- stop poor regrowth from becoming a future hazard
A cheap rough job often ends up being expensive twice. First when it is done, then again when someone competent has to fix the damage.
Healthy Trees Are Assets When They Are Managed Properly
Well-maintained mature trees add shade, make outdoor areas more usable, and improve the look and feel of a property. In Perth’s climate, that shade is worth having. But a tree only stays an asset if it is safe, appropriately managed, and suited to the site.
“A good tree adds value. A neglected one can become a liability in a hurry.”
That is the plain truth of it.
How to Choose the Right Arborist in Perth
What To Look For
When choosing an arborist, look for:
- local experience
- proper qualifications
- clear insurance
- written quotes
- practical explanations, not sales fluff
- evidence they understand Perth conditions and common species
- the ability to handle routine work and more technical jobs
Tree Amigos has been operating across Perth since 1998 and has worked with homeowners, developers, councils, Main Roads WA, ECU, and property managers over many years. That breadth matters because different sites bring different pressures, and the crew needs to be able to adapt without making a meal of it.
Red Flags To Avoid
Be cautious if you hear:
- “We’ll just lop it.”
- “No need for paperwork.”
- “Cash only.”
- “She’ll be right.”
- vague answers about insurance
- no mention of access, safety, or clean-up
- pressure to remove a tree before it has been properly assessed
That sort of approach is usually all hat and no cattle.

Practical Checklist: When an Arborist Is the Right Call
If you are not sure whether to pick up the phone, this short checklist helps.
You probably need an arborist if:
- the tree is larger than routine garden maintenance
- the work is near a house, fence, shed, pool, or driveway
- there is deadwood, lean, cracking, or visible decline
- the tree was previously lopped
- you are dealing with storm damage
- roots, branches, or tree condition are causing concern
- you need written advice, reports, or council-related support
So, what does an arborist do? Quite a lot, as it turns out.
An arborist assesses tree health, manages risk, carries out skilled pruning, removes hazardous trees safely, grinds stumps, responds to storm damage, and helps clients make sensible decisions about what stays, what goes, and what needs attention now. The job is part science, part trade, and part judgement earned over years of hands-on work.
Around Perth, where trees grow hard, sites can be tight, and weather can turn quickly, that experience is worth its weight in gold. Sometimes a light remedial prune is enough. Sometimes the safest answer is removal. The important thing is getting advice based on what the tree is actually doing, not a guess from the front verge.
If there is one thing I would leave you with, it is this: better to deal with a tree problem early than after it lands on the shed.
A good arborist will tell you plainly what matters, what can wait, and what the safest next step is. That is what proper tree care should look like.
