Species Overlays

Species overlays produce a list of taxa that may occur in a defined area, based on our observation data, range maps, and predictive distribution models. The list includes the current number of documented observations in the defined area, the most recent documented date of observation within the defined area, and whether or not the species is predicted to occur within or near the defined area.

Requests for species overlays are filled free of charge. Use our Data Request Form to request a species overlay or to request more detailed observations.
