History of the SuperSanctuary

The Early Years

A young visitor to the Harris Center in the 1980s.In the 1980s, New Hampshire’s development boom reached a fever pitch. The last farm in Nashua was sprouting pavement. Bobcats had disappeared from Amherst and Bedford, and migratory songbirds were in double trouble — grappling with habitat loss in their tropical overwintering grounds, as well as forest fragmentation in the Northeast.

What should a nature center do?

At that critical moment, the Harris Center decided to expand on its environmental education work by becoming a land trust. The goal was to demonstrate how people could work together to protect land from development, with a focus on connectivity.


The Case for Clustered Open Space

Former Harris Center director — now Naturalist Emeritus — Meade Cadot made a compelling case for protecting land in clusters, rather than in isolated parcels. Clustered open space:

  • ensures contiguous blocks of habitat for far-ranging species like bobcat, moose, otter, and black bear;
  • provides forest interior, which is needed by some migrant songbirds;
  • maintains forests large enough to manage for both timber and wildlife;
  • offers opportunities for backcountry recreation, such as camping, hunting, and trekking;
  • preserves scenic drives, with viewsheds that can be enjoyed by all ages; and
  • protects not only shorelines, but entire watersheds for current and future wellheads, reservoirs, and other vital drinking water resources.

Growing the SuperSanctuary

By protecting land abutting these nodes and making connections among them, we’ve now grown the SuperSanctuary to some 35,000 acres across a 120-mi2 portion of the Monadnock Region. Today, it includes:

  • 16 hills and mountains more than 1,500 feet in elevation,
  • 5 lakes over 100 acres in size and 10 smaller ponds,
  • 59 miles of rivers and streams,
  • 13 miles of hiking trails, several scenic roads
  • more than 1,600 acres of diverse wetlands including floodplain, swamp, marsh, fen, and wet meadow.

Tools of the Trade

Over the years, the most important tool has been the conservation easement, in which landowners retain ownership of a property, but donate or sell the development rights to a land trust.


Working Together

We’ve worked closely with far-thinking families, individuals, towns, agencies, and non-profit organizations — some of whom are listed below — to make the SuperSanctuary a reality.  Our philosophy is that bigger is better, and the key is not who protects what, but what gets protected.
