The purpose of these vegetation surveys was to verify the distribution and health of whitebark pine stands in several California National Forests, ground-truth polygons designated by USFS CALVEG as Whitebark Pine Regional Dominance Type and conduct modified rapid assessments and reconnaissance surveys (recons) on whitebark pine and related stands.
The California Native Plant Society (CNPS), working in collaboration with the US Forest Service, initiated field surveys in the summer of 2013 to assess the extent and status of whitebark pine in areas lacking ground surveys in California. Three national forests in the Sierra Nevada and four national forests in the Cascades and Klamath Mountains were selected for field surveys in 2013. Lake Tahoe Basin Management Unit, in the Sierra Nevada area, was added in 2014. Locations were targeted for the assessment based on potential occurrence of healthy stands in high elevations. Post field assessment, photo interpretation and delineation of whitebark pine extent beyond field surveyed areas were also conducted. This information is being used, along with other reputable sources, to develop a distribution map of whitebark pine in California.
