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. Most of these fact sheets were written when the species were on the state list of rare species, and were updated only with the change of status.
