Growth, Drought Response, and Genomic Structure Data for Whitebark Pine in the Sierra Nevada of California

These data represent stem growth, needle length growth, and carbon stable isotope ratios from whitebark pine at 27 sites in the Sierra Nevada of California. Values for stem growth were derived from increment cores, processed following standard methods. Needle characteristics were derived from individual trees with needle initiation years opportunistically selected needles for processing. Needle length was measured in the field, with average length determined from three needles per tree and initiation year. For stable carbon isotopes, samples were pulverized in the lab, weighed, and processed at the Analytical Laboratory at the University of California, Davis. Climate data for each site was extracted from the Basin Characterization Model. Samples were also compared against genomic data collected at the same trees.
