These maps are a digital representation of the individual tree species range maps of the Atlas of the United States Trees by Elbert L. Little, Jr. The atlas shows the natural distribution or range of the native tree species of North America. These coverages represent 3 volumes of the atlas.
These data were collected to quantify oak mortality during the 2014-2017 drought. 30 tenth hectare drought plots were established throughout the blue oak woodland of Sequoia National Park. Information on species, size, and mortality were collected for all standing trees in each plot. In addition, two long-term 2.25 ha plots were established, in which the same data were collected. These data are associated with the following publication: Das, A.J., Ampersee, N.J., Pfaff, A.H., Stephenson, N.L., Swiecki, T.J., Bernhardt, E.A., Haggerty, P.K. and Nydick, K.R., 2020. Tree mortality in blue oak woodland during extreme drought in Sequoia National Park, California. Madroño, 66(4), pp.164-175.

These data were extracted from the CALVEG Existing Vegetation tiles, using the CWHR forest cover type - Blue Oak and clipped to the Sierra Nevada Zone for the CA LCC.These CALVEG Existing Vegetation tiles have been crosswalked to other classification systems, including the California Wildlife Habitat Relationship System (CWHR).The CWHR habitat classification scheme has been developed to support the CWHR System, a wildlife information system and predictive model for California's regularly-occurring birds, mammals, reptiles and amphibians. When first published in 1988, the classification scheme had 53 habitats. These habitats â except the non-vegetated Barren habitat â are described in detail in the CWHR publication...
Blue oak tree-ring chronologies correlate highly with winter–spring precipitation totals over California, with Sacramento and San Joaquin river stream flow, and with seasonal variations in the salinity gradient in San Francisco Bay. The convergence of fresh and saline currents can influence turbidity, sediment accumulation, and biological productivity in the estuary. Three selected blue oak chronologies were used to develop a 625-year-long reconstruction of the seasonal salinity gradient, or low salinity zone (LSZ), which provides a unique perspective on the interannual-to-decadal variability of this important estuarine habitat indicator. The reconstruction was calibrated with instrumental LSZ data for the winter–spring...
