Pruning Regulation to Protect the Critical Root Zone
The health and well being of the trees in our urban forest is directly related to the condition of the roots of these trees. The critical root zone is the underground area that contains the most important types and amounts of a tree’s roots. It is this area that requires protection if a tree is to survive and remain structurally stable.
The health of the critical root zone can be damaged by:
- Cutting roots
- Excavating surrounding soil
- Applying chemicals
- Compacting surrounding soil
- Applying any material that impedes the flow of water or air to the roots
By enforcing the appropriate municipal ordinances, the Forestry Division helps protect the critical root zone of trees under its jurisdiction.
