Tree risk mitigation · London, ON

Sometimes the answer isn’t removal.

Trees and properties have to coexist. We work out what’s creating the risk, and whether a reasonable intervention can reduce it while the tree stays.

What risk mitigation is

Reduce the risk. Keep the tree.

Risk depends on three things: how likely something is to fall, what could be affected, and the consequences that could follow. Before we recommend anything, we look at the tree, its structure, its surroundings and how the property is used.

The goal isn’t zero risk. It’s reasonable risk, managed carefully.

“The goal isn’t to choose an intervention. It’s to find the least intervention that reasonably manages the risk.”

Signs worth a closer look

A defect doesn’t automatically mean removal.

These may be important, but their presence alone doesn’t tell us what should happen next.

01

Dead or damaged branches

02

Cavities

03

Weak unions

04

Long or heavily extended limbs

05

Limbs over roofs, structures or service lines

06

Or another concern you’ve noticed

What matters is context: what the condition means for this tree, this property and the consequences if it failed.

Ways we can reduce risk

The solution should fit the problem.

Risk mitigation isn’t one technique. The right response depends on the tree, the concern and the property.

01

Clearance pruning

Create the clearance that’s needed, without removing more canopy than necessary.

Selective pruning can create separation from roofs, structures, service lines and other infrastructure while keeping healthy canopy and good structure.

02

Weight & end-weight reduction

Reduce mechanical loading while keeping the tree.

Strategic reduction can lower the leverage on long or heavily extended limbs while keeping as much functional canopy as reasonably possible.

03

Cabling & bracing

Extra support when a structural concern can reasonably be managed.

Cables or braces can sometimes reduce movement and add support. They aren’t right for every defect, but can be useful as part of a broader management plan.

04

Deadwood & defect management

Deal with the part of the tree causing the concern, not automatically the whole tree.

Dead, damaged or compromised branches can sometimes be managed one by one, so the healthy, functional parts of the tree can stay.

Do enough. Not everything.

One concern, several possible responses

Removal is one option, not the starting point.

When work is warranted, we aim for a response that matches the concern.

  • If one limb is the problem, the whole canopy may not need pruning.
  • If pruning can manage the concern, cabling may not be necessary.
  • If cabling and pruning can reasonably manage the risk, removal may not be necessary.
  • If those measures can’t reduce the risk enough, removal may be the responsible recommendation.
01

No action

Sometimes the tree is best left as it is.

02

Monitor

Sometimes watching it over time is the right call.

03

Manage the target

Changing what sits under the tree, rather than the tree itself.

04

Prune

Selective cuts with a clear purpose.

Pruning & Tree Care

05

Cable / brace

Added support for a structural concern that can reasonably be managed.

06

Remove

If other measures can’t reduce the risk enough. Crane work when a job calls for it.

Tree Removal

Not a sequence. These aren’t steps toward removal. They’re different possible responses, and the right one depends on what the assessment supports.

Before the work

First, understand the risk.

Risk mitigation starts with assessment, not equipment. Before recommending pruning, cabling, target management or removal, we need to understand what’s actually creating the risk.

01

Condition & structure

What’s present, and how significant is it?

02

Likelihood of failure

How likely is the tree, or the relevant part, to fail?

03

Targets

What people, buildings or property could reasonably be affected?

04

Consequences

What could happen if failure occurs?

05

Mitigation options

What reasonable measures could reduce the risk?

The work is already clear

“I know what work I need.”

A free quote may be the right place to start.

  • You’ve already had the tree assessed
  • Or the job is clearly defined, such as removing a dead branch or pruning for clearance
The right response isn’t clear

“I’m concerned, but don’t know what should be done.”

Start with a Certified Arborist Assessment.

  • You’ve noticed a limb, defect or other concern
  • You’re not sure what it means, or whether anything needs doing

Tree risk assessment

Risk decisions need more than a visual opinion.

When risk is the concern, your tree is assessed by Jason Korkidakis, Owner & Lead Arborist: ISA Certified Arborist (ON-3263A), TRAQ qualified and PPQ qualified, with a decade of experience and more than 5,000 tree assessments.

TRAQ in plain English: a qualification in assessing tree risk step by step, looking at the tree, how likely it is to fail, what it could hit and what would follow.

That framework moves past “does this tree have a defect?” to the more useful question: what does that defect actually mean for your tree and your property?

“I was told that I would have to cut down my 80 yr. old Maple tree... it was devastating news. A close friend urged me to call Koala Tree for a second opinion. When Jason said he thought he could save it, I was 'over the moon' ! He and his team worked tirelessly, getting the tree to a point where it will be able to survive the winter and regain its health. … my beloved Maple tree has been given another chance and, I will be forever grateful to Jason, … and the entire team at Koala Tree, for their commitment and dedication. You guys are the best!”

“The Koala team did an amazing job removing trees and trimming the growth on our property. Jason and his team are courteous and respectful while working and we were specially appreciative of the tree health advice. The Koala team shows that they really care about our Forest City in the work they do.”

Warren Helland · Google review

“We have been having Jason and his crew … manage our trees for the last several years. We have been very impressed with the care and respect they have shown while on our property. They are extremely professional how they go about their business. The work is done in a timely manner and they work very hard to make sure that everything is cleaned up and left in a neat and tidy condition. We will continue to have Jason take care of our trees.”

FAQ

Questions people ask

Does a defect mean my tree has to come down?

Not automatically. A cavity, weak union, dead branch or heavily extended limb may be important, but its presence alone doesn’t tell us what should happen next. What matters is what it means for this tree, this property and the consequences if it failed.

Is the goal to make my tree risk-free?

No. The goal isn’t zero risk. It’s reasonable risk, managed carefully, using the least intervention that reasonably manages it.

How can you reduce risk without removing the tree?

Depending on the concern: clearance pruning, weight and end-weight reduction, cabling and bracing, or managing deadwood and individual defects. Sometimes monitoring or no action is the right answer.

Is cabling right for every tree?

No. Cables or braces can sometimes reduce movement and add support, but they aren’t appropriate for every defect. They work best as part of a broader management plan.

Will you ever recommend removal?

Yes, if pruning, cabling or other measures can’t reduce the risk enough. Removal is one possible response, not the starting point.

What is TRAQ?

Tree Risk Assessment Qualified. It’s a specialised qualification in assessing tree risk systematically: the tree, the likelihood of failure, what could be affected and the potential consequences. Jason Korkidakis holds it.

Should I get a free quote or an assessment?

If the work is already clear, such as removing a dead branch or pruning for clearance, a free quote may be the place to start. If you’re concerned but don’t know what should be done, start with an assessment. Not sure? Contact us and we’ll help you choose.
