In conjunction with the Forest Service Pacific Southwest Region’s Botany & Rare Plants Program and the California Native Plant Society’s Vegetation Program, we have been working to assess and map populations of whitebark pine in California. Pinus albicaulis is a species of concern across its range because populations are suffering from the synergistic interactions of mountain pine beetleswhite pine blister rust, fire suppression, and climate change. In 2012, Canada listed whitebark pine on the endangered species list because of high mortality rates across the country. This project has been ongoing since 2012 and below are our fieldwork reports.
