Purpose This provisional Biogeographic Analysis Package provides a comparison between the annual Spring Indices First Leaf and 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...

This is an experimental collection that implements an information model for biogeographic information. We are building this on the conceptual foundation from the Global Change Information System. We are using the Biogeographic Information System, accessed via the ScienceBase API, as a basis to drive an experimental new map interface (National Biogeographic Map) and a developing iterative report concept (National Biodiversity Assessment).
