Our Mission

Refuge Purpose(s) 

Each unit of the National Wildlife Refuge System is established to serve a statutory purpose that targets the conservation of native species dependent on its lands and waters. All activities on those acres are reviewed for compatibility with this statutory purpose.  

The primary purposes of Supawna Meadows NWR are for:  

Opportunities  

  •  “...use as an inviolate sanctuary, or for any other management purpose, for migratory birds....” The Migratory Bird Conservation Act (16 U.S.C. §715d);

Our History

In 1934, President Franklin D. Roosevelt established the Killcohook Migratory Bird Refuge along the Delaware River. For many years, the site was used by the U. S. Army Corps of Engineers to deposit dredge spoil. The dredge spoil built up on the site, which decreased Killcohook's value for wildlife, and spurned local conservationists to pursue purchase of adjacent lands to create a wildlife refuge with habitat value.

The U.S. Fish and Wildlife Service purchased the first 653 acres of refuge land from the Philadelphia Conservationists (now known as Natural Lands Trust) in 1971. In 1974, the Service named the site Supawna Meadows National Wildlife Refuge to make it distinct and separate from Killcohook. The Service exercised its secondary jurisdiction over the Killcohook Migratory Bird Refuge until it was revoked by Congress in October 1998. Killcohook is still used as a confined disposal facility by the Corps of Engineers.
