White pine blister rust and whitebark pine in Washington

Описание: Whitebark pine (Pinus albicaulis) has a long, complicated history with the tree disease white pine blister rust, which is caused by the non-native pathogen Cronartium ribicola. White pine blister rust is one of several disturbance agents that threaten the health and persistence of whitebark pine across North America. This presentation will discuss the biology and epidemiology of C. ribicola, the distribution of the disease in Washington, and how we incorporate natural genetic resistance to the disease into whitebark pine restoration efforts.
