Land is our common ground.
Since 1960, The Carlisle Conservation Foundation (CCF) has worked to preserve natural beauty and open space in Carlisle, Massachusetts. CCF was established as a private organization to work with the town, individual land owners and other organizations to protect open space for wildlife habitat, passive recreation, and scenic vistas; to provide education on local species; and to promote responsible development practices. By connecting land owners with volunteers and professional services, CCF helps preserve natural resources in Carlisle for all to enjoy.
Preserving open space is our common goal.
As an independent non-profit organization separate from town government, CCF advocates, encourages, and facilitates open space preservation through a wide range of land-ownership options, from limited development to government and private purchase. CCF also works with individuals and organizations to enforce wetlands protection, optimize and supervise subdivision and road planning, and sponsors education and advocacy efforts in our schools and community.

Some of our success stories.
Every conservation story begins with a landowner. CCF helps owners achieve their goals by providing the support and knowledge necessary to protect their land in perpetuity. To view a complete list properties owned and protected by CCF, click here.
Spencer Brook Reservation
The Spencer Brook Reservation, over 30 acres of wetlands, woods and fields, is located at the intersection of South and West Streets. It was the first property acquired by CCF, launching the organization on its more than 60-year mission of preserving the natural beauty & rural character of Carlisle. The land was deeded to CCF in 1960 by A.E. “Ben” Benfield.

Benfield Conservation Land
The Benfield Conservation Land, located on South Street in the southwest corner of Carlisle, was acquired by the Town in 2004, part of a coordinated effort initiated by CCF to address conservation, recreation, and housing needs. The 25-acre conservation parcel (of the 45-acre purchase), with gently sloping fields leading past large pines to a platform with views across Spencer Brook, is accessible via a path behind Benfield Farms housing.
Poole's Swamp
Poole’s Swamp is a 15.2 acre wetland off School Street, home to water fowl, beavers and a multitude of native plants. The land was purchased by CCF in 1998 and was further protected by a conservation restriction held by the Town. A tributary of the Spencer Brook, these wetlands serve a vital role in flood control and water purification in addition to their role as habitat for a variety of flora and fauna.
Clark Farm
Clark Farm, located on Concord Street, has been in agricultural production since the early 1700s, and before that was part of a geographic area home to the Musketaquid Indians for thousands of years. Today CCF holds CRs for Clark Farm and the surrounding fields that protect the land from development and preserves the open and bucolic nature of the working farm in perpetuity. The views from Concord and School Streets are a permanent reminder of how open space beautifies our town and maintains its rural feel, which is so important to our mission of conservation.
Upcoming Events
