Public Tree Inventory

Our inventory of trees found in parks, road rights-of-way and town facilities.

The Town of Oakville is currently updating its public (town-owned) tree inventory by updating the information, including condition rating, of all of the trees found in parks, road rights-of-way and town facilities.

The project’s goal is to re-inventory 170,000 trees in two phases: the first from January to December 2022, covering the area south of the Q.E.W. highway and the second from January to December 2023, covering the area north of the Q.E.W. highway.

Data was last collected in 2009 when the town and its partners. The GIS-based tree inventory is Forestry’s foundation for its asset and urban forest management.

Within additional tabs, the web map application also shows:

  • All town-owned street and active parks trees, including existing trees, those scheduled for removal, recently removed, treated ash trees and trees scheduled to be planted.
  • Woodlands Hazard Abatement. Removal of dead and dying ash trees to reduce the risk to the public and to help our woodlands regrow.
  • Woodland Regeneration. We're helping our woodlands regrow after the impact of EAB.
  • Engineer Soils. Specialized underground structures where trees are planted.
  • Memorial Tree Program. A tool for residents that gives them the opportunity to adopt a tree in memory of a loved one. 
  • LDD moth: Delineations of the most recent aerial spray program for the management of defoliation from LDD moth.

Public vs. private tree ownership

Ownership of a tree is determined by the physical location of the tree, not who planted the tree. If the tree is on your property, then you are responsible for the maintenance of the tree. If the tree is on a municipal right of way, the town is responsible for the tree.
