Report a tree issue

Help us maintain the health of London’s trees by reporting tree issues. Early reporting can help us contain diseases, save trees and prevent damage.

Use the form below to request

  • Trimming, elevating low limbs or removing dead branches
  • Inspection for poor health, infestation, and storm or wind damage
  • Having a tree to be planted

Report a tree-related issue using the button below.

City-owned or private tree

All city-owned trees are mapped. Type an address into Trees CityMap or use the map to explore the inventory of trees in parks, on Thames Valley Golf Course and along boulevards and pathways.

Once you've created your desired map view and found an address or park, use the blue "I want to" button to add the tree layer to the map. Full instructions are available here.

A green dot indicates a city-owned tree. You’ll also learn: 

  • Common name
  • Latin (scientific) name
  • Trunk diameter (cm)
  • Year observed
  • Inventory number

Provide the inventory number when contacting the City of London's Forestry Operations Division about a concern or problem with a tree on municipal land.
