The 16,000-acre Southeastern Massachusetts 
Bioreserve was the state’s first bioreserve, 
formed in 2000 by a unique agreement 
between public and private partners. These 
lands are permanently protected and managed 
cooperatively in a manner to preserve the 
functionality of this large-scale ecosystem and 
promote biodiversity, conservation, water 
supply protection, and scientific, educational, 
and recreational opportunities
