The Wyoming Natural Diversity Database (WYNDD) maintains a computer database of the locations and biological characteristics of rare plants, rare animals, and important plant communities in Wyoming. The database is in a standard format used by the nationwide network of Natural Heritage programs. Location and biological information from the database is available to the public through data requests submitted to WYNDD.

This raster represents a binary prediction of distribution (present/absent) for the species based on inductive modeling of environmental suitability. WYNDD defines the distribution of a species as the fine-scale environments within its range that are suitable for occupation. A common modeling algorithm, Maxent (Phillips et al., 2004), was used to generate predictive distribution models for Wyoming's Species of Greatest Conservation Need. The resulting models were clipped to the species' respective ranges (Keinath et al., 2010). References: Keinath, D.A., M.D. Andersen and G.P. Beauvais. (2010).

Source Feature Occurrence Records: Distributed in data requests as individual observations of a single species or vegetation community at a specific location on a specific date, represented by polygons depicting the locational uncertainty distance in meters. Contact WYNDD for further information.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
