Arborist Reports 101

What is an Arborist Report?

Arborist reports document the condition of the tree, note issues, damage or areas of concern, and provides information about the cause of issues including site conditions, pest or disease threats, or mechanical injury. Recommendations actions should be noted, which may include site remediation, increasing vigour through fertilization or injections, pest control, air spading to examine and treat root issues, or pruning and removal if needed.

Arborist reports are also required to meet City by-laws in many municipalities, as one of the documents required to obtain permission to remove a tree.

Do I Need an Arborist Report?

City Forestry Department websites will provide information on whether arborist reports are needed in your community.  Communities vary in their bl-law requirements for tree protection.  Please contact your City website, or call City information line, to get information about your specific project requirements.

Why are Arborist Reports Important?

Arborist reports help provide information about the health and condition of specific trees; the cause of the problem, and actions that may be taken to alleviate the problem. Arborist reports are also important to City Foresters to help determine which trees can be taken down without undue loss to the community.

As an example, a native butternut in good condition is a rare tree that requires protection, while a dead or diseased tree may be taken down with replacement trees to be planted, to ensure long term health of the urban canopy. City Foresters work hard to preserve and enhance the beauty, environmental benefits, and public safety of the urban forests in our communities, which benefits all.
