The Lake Simcoe Region Conservation Authority...

The Lake Simcoe Region Conservation Authority was granted approval to use herbicides to manage and control the spread of invasive tree species in the red pine plantation in the Durham Region Forest.

Environment Canada is sponsoring the invasive alien species partnership program as various alien tree and shrub species have become established throughout the Lake Simcoe watershed.

The species have the potential to displace natural species.

The program includes cutting or the girding of certain trees, followed by the application of herbicide to ensure the tree or shrub won't regenerate.
