The site contains five wetland plant communities that are in excellent condition and supports the state-candidate Makah copper butterfly species and the state sensitive Olympic mudminnow. The preserve also supports priority habitat features including shorebird and waterfowl concentration areas, harbor seal haul out and pupping areas, and Roosevelt elk and peregrine falcon wintering areas.  
Features Protected: Makah copper, Olympic mudminnow, shore pine-western redcedar/sweetgale/sphagnum plant community, western redcedar-western hemlock/skunk cabbage plant community, and seven wetland ecosystems (including cold springs, salt-marshes of varying salinity, a bog and a freshwater wetland)
