WYNDD develops and maintains lists of species in Wyoming that are rare, endemic, disjunct, threatened, or otherwise biologically sensitive, and supporting documentation. Previously, we published "Species of Concern" lists as PDF documents, on our website. We now offer access up-to-date versions of these lists via the Species List application. Use the links in the table below to access current lists of species meeting taxonomic and/or status criteria, or create your own, custom list, using our Species List application.
