More good years for an aging tree.

When a mature tree starts to decline, removal isn’t the only option. We set clear, achievable goals that help prolong its life and limit risk as it ages.

What decline management is

A plan for the years ahead, not a one-off job.

Decline management is a planned series of goals for a mature tree that’s starting to decline. The aim is to prolong its life and limit the risk to people and property as it ages.

It suits mature and veteran trees that are worth keeping and can still be managed safely. If that changes, the plan changes with it.

Clear, achievable goals that prolong a tree’s life and limit risk as it ages.

Signs of decline

What decline can look like.

Decline is often gradual. These are some of the signs we look for.

01

Thinning canopy

02

Dieback in the crown

03

Early leaf colour or leaf drop

04

Deadwood

05

Fungal growth at the base or trunk

06

Cracks or cavities

07

Soil or root disturbance from construction

08

Or another change you’ve noticed

Some of these have more than one cause, which is why we start with an assessment.

How we approach it

Goals first. Then the right tools.

Every plan starts with what we want to achieve for the tree and the property. The tools follow from the goals, and not every tree needs all of them.

01

Assessment and goal-setting

Jason assesses the tree’s structure, health and risk, then agrees realistic goals with you.

Those goals shape everything that follows: what work is done, in what order, and how we’ll know it’s working.

The tools

02

Decline management pruning

Targeted, conservative pruning to reduce load and deadwood.

Not heavy cutting. Each cut has a purpose, and we keep as much healthy canopy as we reasonably can.

03

Cabling & bracing

Supplemental support for weak unions or heavy limbs, where appropriate.

Cables and braces can add support and limit movement. They aren’t right for every defect. Cables last 10+ years, and we check them once a year.

04

Tree health & soil care

Better growing conditions around the roots.

Mulching, AirSpade soil decompaction and soil testing, where the assessment shows they’ll help.

05

Monitoring

Planned check-ins, so the plan keeps up with the tree.

We visit twice a year to see how the tree is responding and adjust the plan.

Prolong its life. Limit the risk.

When removal is still right

If a tree is past managing, we’ll tell you plainly.

Decline management isn’t about keeping a tree at any cost.

  • If the risk can’t be brought to an acceptable level
  • If the tree is past the point where management makes sense

In either case, we’ll say so and plan a safe removal.

More about Jason

“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!”

FAQ

Questions people ask

Can you save my declining tree?

Often we can extend its life and reduce the risk, but not always. Some trees are too far along, or the risk can’t be brought to an acceptable level. The assessment tells you which before you spend money on work.

Is cabling safe? How long does it last?

Installed where it’s appropriate, cabling can add support to weak unions or heavy limbs. It doesn’t make a tree risk-free. Cables last 10+ years, and we check them once a year.

How long does decline management take?

It’s ongoing. A plan runs 5+ years, with two visits a year to check on the tree and adjust the plan.

Is it cheaper than removal?

It depends on the tree, the goals and the work involved. A free quote prices specific work, and an assessment helps you decide what’s worth doing.

Do I need a permit?

It depends on the tree and the work. See our Permit Package for when a permit may be needed and how we can help.
