King George Park is a good example of the risks associated with monoculture. At the time, black locust trees were massively planted. This species represents 33% of the trees in the park and all of them are affected by the same insect pest.

Herbivorous insects are specialists; they can only cause damage on a limited number of related species.

Mixed forests are more resistant to attack, hence the importance of biodiversity.

Several tree species will be planted as dead and hazardous trees are removed or treated. The following are the tree species considered, based on recommendations from outside experts.

Juniperus virginiana
