Questions to ask:
- Are there large dead branches on the tree?
- Are there detached branches hanging in the tree?
- Does the tree have cavities or rotten wood along the trunk or in major branches?
- Are mushrooms present at the base of the tree?
- Are there cracks or splits in the trunk or where branches are attached?
- Have any branches fallen from the tree?
- Have adjacent trees fallen over or died?
- Has the trunk developed a strong lean?
- Do many of the major branches arise from one point on the trunk?
- Have the roots been broken off, injured or damaged by lowering the soil level, installing pavement, repairing sidewalks or digging trenches?
- Has the site recently been changed by construction, raising the soil level or installing lawns?
- Have the leaves prematurely developed an unusual color or size?
- Have trees in adjacent wooded areas been removed?
- Has the tree been topped or otherwise heavily pruned?
Common Site Impacts:
Urban Trees
- Regrowth from topping, line clearance or other pruning.
- Broken or partially attached branch.
- Open cavity in trunk or branch.
- Dead or dying branches.
- Branches arise at one point on the trunk. i.e. a “broom” look
- Decay and rot present in old wounds.
- Recent change in grade, soil level or other construction.
Rural Trees
- Recent site construction, grading and tree removal; clearing of forests for development.
- Previous tree failures in the local area.
- Tree leaning near target.
- Forked trunk; branches stems equal in size.
- Areas with rocky or saturated soils.
