Pine Beetles
Pine beetles (mountain pine beetle (MPB) and Ips beetles) are native to our forests, but their populations are on the increase due to climate change and the unhealthy state of our forests. Climate change has made for warmer winters, so more beetles are surviving the winters. Our trees are stressed due to old age, drought, and high density, making them less able to defend themselves from beetle attack. An MPB epidemic is heading our way, and the experts predict that none of our lodgepole pine will survive. We may be able to save some of our ponderosa pines, however, by acting now to thin those forests, thereby reducing density and increasing tree vigor. CWPP projects aimed at reducing wildfire risk through tree thinning will also increase forest health and beetle resistance. Once we have done our best to create a healthy forest, non-toxic products like verbenone may help protect our trees.
Unfortunately, the recent increase in beetle populations means that the logs and slash produced by these projects must be managed appropriately, adding to the cost. In addition, beetle-infested trees should be removed before the beetles reproduce and fly to attack new trees, also adding to the costs of forest management. For more information about pine beetles, how to manage thinning projects appropriately, as well as how to recognize and get rid of “hot” beetle trees, please read on.
