Threats to Our Urban Forest

Insects and Disease

The urban forest is an asset worthy of protection from insect and disease pests. Public awareness and the help of citizen science can be part of the solution. By being vigilant about the pests that threaten our trees and calling in to the City of Saskatoon Urban Forestry department we may be able to help curb some infestations. More about the City of Saskatoon pests here.

Development and Urban Expansion

Boulevard and back yard trees have suffered immensely from construction that compacts the soil over the roots and even the removal of specimen trees. For information on tree protection requirements go to the City's link here:

Climate Change

Climate change is one of the biggest issues of our time. The predicted changes in our climate are likely to inflict particular stresses on the trees and other plants. We need to keep the trees as healthy as possible so that they can be resistant to drought and the attack of emerging insects and pests. Early detection and monitoring of these threats is vital.


People injuring or even killing trees is a reality within the urban forest. Boulevard trees have been poisoned by homeowners that didn't want trees near their property. Branches torn off, stripping of bark, or roots dug up can cause damage to the structure and health of a tree. These trees are not meant for one homeowner but rather the entire community to enjoy. Citizens can take action by calling in to the City of Saskatoon, Urban Forestry department to report activity and damage. 306-975-2890
