Park Preservation

We have inherited “America’s best idea,” our national parks. They guard, protect, and share millions of acres of irreplaceable landscapes, plants, and animals. They also preserve nationally significant historical and cultural places and tell the stories of people who made great sacrifices for our country.  

Parks are our classrooms, playgrounds, and places of escape and peace. They let us experience solitude and quiet, natural sights and sounds undisturbed by civilization, and beauty as simple as skies so dark you can see by starlight. The National Park System is ever-changing. There are new lands, water,  plants, and wildlife to protect, and as time passes, new history to commemorate. You can help us ensure that our parks are treasured forever.

Our preservation and conservation projects work to acquire the missing pieces of our national parks, the privately owned land located within and adjacent to our national parks’ boundaries. See the lands and landmarks we’ve added to our National Park System near you and across the nation in the map below.

By making a donation to the National Park Trust, you ensure that our parks and public lands are treasured forever.

    In December 2017, the Park Trust completed the acquisition of a parcel of land on Lake Quinault in Olympic National Park (WA) – just under 0.5 acres. Although small in size, it is big in ecological significance. The parcel was surrounded on three sides by Olympic National Park; it was the only parcel in that block that did not belong to the National Park Service. Its acquisition will keep it in its natural state by preventing further development.

  • St. Croix National Scenic Riverway, WI

    National Park Trust added 145 acres to the St. Croix National Scenic Riverway. The complex project involved a land exchange in which the Park Trust worked with the Wisconsin Board of Commissioners of Public Lands to identify and then purchase valuable timberland; then that land was traded for three parcels of land owned by the State of Wisconsin in the north-central part of Wisconsin. Those three parcels were then transferred from the Park Trust to the National Park Service within days of taking ownership.
