How We Do It

We protect land using a variety of tools. 

Our direct land acquisition and easement work creates parks and preserves, adds to public lands, protects farmland and historic viewsheds, and enables long-term conservation management.

Through our grants and loans we partner with local land trusts in targeted geographies to safeguard habitat and water; protect resilient landscapes in response to climate change; and support community forests.

And our parks program raises private dollars to make parks more welcoming, inspiring and enjoyable to the public.

As a national leader in the land conservation community, we ably tackle complicated land deals; support and lead partners to achieve complex acquisitions; foster the growth of grass-roots engagement on a host of environmental issues; and through our climate research, provide lands trusts the tools they need to target terrains that are most likely to offer ecological havens in the future.
