Mountain pine beetles continue to flourish in Jasper National Park, due in part to the unusually warm winter. Because of the continued growth, the Park is developing a strategy to try to minimize the effects of the beetle going forward. As explained in this article from The Jasper Fitzhugh, one program involves distributing verbenone pouches to residents. The pouches can be attached to trees, and release a pheromone that protects the tree by telling beetles that the tree is already colonized.
