Residents of Ottawa have witnessed and lamented the loss of 50,000 ash trees on city property alone destroyed due to an impact of climate change: the steady northern advance of the Emerald Ash Borer. Untempered intensification in the urban core is destroying front and back yard trees and dramatically reducing space for new trees. Wind and ice storms have also taken their toll. 

Now you can record the lost trees and your memories on our interactive map. It allows you to:

  • plot lost trees due to human or natural causes.

  • record details such as tree type (species), approximate date of loss and size.

  • add a photograph and comments.

  • view the cumulative count of loss, by cause and by City ward.

Thanks to support from Ersi Canada the app is easy to use. The data will be integrated with other mapping initiatives down the road.
The project is an initiative of BigTrees of Kitchissippi, Community Associations for Environmental Sustainability (CAFES), The Greenspace Alliance and Ecology Ottawa.
