First Bloom Spring Index

Summary

Purpose This provisional Biogeographic Analysis Package provides an analysis of an annual Spring Index, First Bloom, within the user-selected area of interest. Change in the timing of seasonal biological events (phenology – e.g., leaf-out, migration, and reproduction) is one of the most proximate responses to climate change. Information on phenological changes supports managers in adjusting the timing of activities such as treating invasive species, operating visitor facilities, and scheduling climate-related events (e.g., flower festivals, autumn leaf-viewing). Recent work shows that 53% of natural resource parks managed by the United States National Park Service are experiencing extremely early springs (that is, earlier than 95% [...]
