The Natural Heritage & Endangered Species Program creates fact sheets for many species on the Massachusetts Endangered Species List (MESA List) to provide information on the life history, distribution, and status of these species to the public.  This page includes fact sheets for species that have subsequently been removed from the MESA List. Please note that fact sheets are not available for all species in Massachusetts, or for all species that have ever been on the MESA List.
