Celebrating 50 years of saving land for people, for wildlife, forever
What We Protect
We protect land that supports the things we can't live without - like clean water, climate protection, and healthy communities - and safeguard the places that make life worth living, like parks for recreation and plant and animal habitat.
How We Do It
Over the past 40 years, we've helped save millions of acres through land acquisition, funding, and research and advocacy. We're also increasing access to the great outdoors through the support of grassroots efforts and park enhancement projects.
