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.
