Genetic Program - Whitebark Pine Conservation
View a photo essay
on whitebark pine by Carol Aubry.
Based on growing concerns of the health of whitebark pine ecosystems in Oregon and Washington, the PNW Genetic Resource Program began work in the early 1990's with the PNW Forest Health Protection Program, USDI National Parks and others to gather information on the status of whitebark pine in Oregon and Washington. Early work included an informal information survey, seed collections to be used to examine natural genetic resistance to white pine blister rust and common garden studies to examine genetic variation, germination tests to examine longevity of seed in cold storage and germination procedures, protocols to grow whitebark pine seedlings, and surveys of the health of whitebark pine ecosystemssee publications and posters)-->. Beginning in 2004, this work has intensified and a four year 'Pacfic Northwest Albicaulis Project' was initiated.
Pacific Northwest Albicaulis Project
The Pacific Northwest Albicaulis Project of the USDA Forest Service endeavors to support the conservation and restoration of whitebark pine ecosystems in Oregon and Washington through field and laboratory studies, publications, and development of management strategies.

Blister Rust Resistance
Region 6 screening for whitebark pine blister rust resistance is underway at Dorena Genetic Resource Center. Naturally occurring genetic resistance to this introduced, invasive pathogen is rare. Current screening will provide information on the frequency of this resistance in Oregon and Washington, as well as identifying resistant parent trees from which seed might be collected in the future for restoration efforts.
Several common garden studies are underway or recently completed. Stay tuned for details.
