London’s Urban Growth Strategy

London developed the Urban Growth Strategy in 2014 to engage citizens and outline the next steps that the city must take to protect and enhance our urban forest.

Diseases

Just like humans, trees are susceptible to disease. Diseases usually occur from open wounds in branches or in the trunk, through trauma-induced defoliation, or through other environmental stressors that weaken the tree.

Pests

There are many pests throughout Southwestern Ontario and in London that have caused extensive damage and death to trees. Typically, these are non-native insects that have been brought over from other countries.

Species at Risk

A number of tree and shrub species are listed under the Endangered Species Act in Ontario. This act seeks “to protect species that are at risk and their habitats, and to promote the recovery of species at risk.”

Non-Native Species

Trees that are not native can pose significant threats to local biodiversity and to the natural ecosystem. Non-native trees tend to reproduce and grow quickly.
