Popis:	Research and management issues related to pine forests, snowpack and refugia are relevant to mountainous ecosystems globally. For this study, we investigated local snowpack longevity as an explanatory variable for whitebark pine performance (survival rate, growth rate and condition). We used Sentinel-2 imagery to monitor local snowpack longevity. This new imagery is spatially and temporally more appropriate than other publicly available satellite imagery, and early results indicate that Sentinel-2 imagery can be successfully used for this purpose. Sites were selected based on a multi-decade management effort by federal agencies to plant whitebark pine in the Greater Yellowstone Ecosystem. Relative to initial planting records, present-day field sampling affords an opportunity to evaluate whitebark pine performance over time. Featured photo from Figure 3 in report.
