A major function of NHESP is to collect information on rare species. This is accomplished through field surveys, literature reviews, and research by staff biologists and cooperators around the state. Information is collected on the abundance, distribution, and conservation needs of rare species and significant natural communities.
Rare species in Massachusetts are threatened primarily due to habitat loss or degradation. Learn more about reporting rare species observations, requesting species information, and get information on conservation efforts for a specific biological group.
