The purpose of the whitebark pine delineations was to more accurately define the extent and acreage of areas in California where whitebark pine dominates (Pinus_albicaulis_Alliance) or is present (Presence_Pinus_albicaulis). This information can be used by agencies and educational institutions interested in stratifying sampling points for future long term monitoring plot placement for the species. Polygons were delineated and attributed using ESRI's World Imagery as a base for the Central Sierra Nevada National Forests (Eldorado, Lake Tahoe Basin Management, Sequoia, and Stanislaus) with 0.30 meter resolution and a 4.08 meter accuracy or less. Imagery was flown in the central Sierra Nevada from 9/1/2010 to 7/4/2011. Polygons were delineated and attributed using Google Earth as a base for the Southern Cascade National Forests (Klamath, Lassen, Modoc, and Shasta-Trinity) from September to December 2013.
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. Please note that this is not a full map of whitebark pine occurrence in California, but only represents areas that were reached during limited field assessments.
