A tree management plan (TMP) is a comprehensive survey or assessment of trees within a designated site or parcel of land. These reports are often used to guide the future use, management, and maintenance of a site. The tree management plan provides base data and information, including the existing health and condition of the trees and any risks that the trees may pose. General information for each individual tree will include:
- Identification:Allocated number and botanical name.
- Dimensions: Tree height, canopy spread, and trunk diameter at breast height (DBH)
- Protection zones: Tree protection zone (TPZ) and structural root zone (SRZ).
- Significance: Tree significance, useful life expectancy, and priority for retention.
- Condition: Tree health, structure, age class, and any significant/visible defects.
- Risk: Risk of harm, risk rating, and mitigation actions.
The tree management plan will include a tree retention value plan. This plan will show the number and location of each tree, the extent of the tree protection zone and will be colour coded to reflect the retention value of each individual tree (low, medium, and high priority for retention). The report will also provide management/mitigation options to reduce or eliminate the risk posed by each of the identified trees.
