Hazard tree assessment is an attempt to answer two
questions:
1- Should a tree be removed, as important structural defects make the tree
unstable and a potential liability to the public agency?
2- Should a tree be pruned, as one or more parts are likely to fail and
target would be hit, such as people, structures or other plants?
Managers must ensure a reasonable level of
safety on a public site. This "duty of care" has been confirmed through
court jurisprudence.
Below is a copy of the "Danger Tree Assessor" certificate issued by The Wildlife Tree Committee of British Columbia
in November 2001.The program is administered by The Wildlife Tree Committee, a multi-agency
committee formed in 1985. It is composed of representatives from the
B.C. Ministry of Forests, the B.C. Ministry of Water, Land and Air
Protection, the Worker's Compensation Board, B.C. Hydro, industry, labour,
and public interest groups.
Certification requires:
- Properly identifying dangerous trees;
- Assessing trees for potential wildlife habitat;
- Assessing trees for failure potential;
- Making appropriate safety decisions.
Also below is a copy of the "Certified Tree Risk Assessor" certificate
issued by the ISA Pacific Northwest Chapter in July 2006.
Obtaining these certificates is an example of our efforts to remain up-to-date
on the latest industry developments.
