This 466-acre site includes the headwaters of Schumacher Creek, the stream and associated wetlands, an upland buffer, and a variety of plant communities that vary in their dominant vegetation. One of the plant communities found at Schumacher NAP, the Sitka alder/skunk cabbage/water parsley community, has a very restricted geographic range; it is only found in the Puget lowlands and is critically imperiled.
