Species of Conservation Concern

 

Twenty-eight species, or almost a quarter of the state's butterfly fauna, warrant conservation concern. These are Uncommon or Rare species, which are Resident (breeding and over-wintering), have limited or specialized habitat, and are either declining according to 1991-2010 MBC records, or may be expected to decline as a result of climate warming and other factors.

The twenty species listed in Section I constitute almost one-fifth of Massachusetts butterfly species. They currently have no legal protection in the state. The additional eight species shown in Section II are already listed under the Massachusetts Endangered Species Act (MESA) as Endangered, Threatened, or of Special Concern.

For all these species, key populations should be monitored and conserved, and suitable habitat should be protected and properly managed.  Follow the link for the full Species Account.
