Through the implementation of MESA, MassWildlife’s Natural Heritage and Endangered Species Program conserves and protects the most vulnerable animal and plant species of Massachusetts and the habitats upon which they depend.
Many rare species have benefited from the protection afforded under MESA and the work of the Natural Heritage and Endangered Species Program (NHESP) over the years, including the peregrine falcon, bald eagle, and northern red-bellied cooter.
There is still a lot to do and in the face of habitat loss, emerging diseases, invasive species, climate change, and other threats, this work is more important than ever!
Donations provide vital support to NHESP's work to protect, manage, and restore the Commonwealth’s most imperiled animals and plants and the sensitive communities and habitats in which they live.
