Sycan Marsh

Sycan Marsh




  • Listed on more than one “valuable wetland” list by natural resource agencies or nongovernment organizations.
  • Protects biological diverse wetland flora, fauna and/or their habitat
  • Supports significant numbers of wetland-dependent fauna, such as water birds or fish

Tens of thousands of waterfowl, waterbirds, and shorebirds of dozens of species utilize the marsh, particularly in spring and summer. Up to 10,000 Tundra Swans can be found at the marsh during their northward spring migration. More than 100 Greater Sandhill Cranes nest on the marsh, as do Black terns and Yellow Rails. Ducks breeding at Sycan Marsh include Cinnamon Teal, Blue-winged Teal, Northern Shoveler, Redhead, Canvasback, Ring-necked Duck, Common Merganser, and Wood Duck. The sedge-dominated marsh is also home to many raptors including Bald Eagle and Goshawk. - Audubon Society

The Nature Conservancy first acquired property at Sycan Marsh in 1980 and today owns over 30,000 acres. Its name comes from a Klamath Indian phrase meaning “level, grassy place.” Surrounded by pine forest in the headwaters of the Klamath Basin, a vast wetland provides habitat to unique and threatened freshwater species. The marsh awakens in early spring to 10,000 tundra swans migrating north along the Pacific Flyway. Many other birds follow, including breeding greater sandhill cranes, black terns, white-faced ibis and yellow rails. Bull trout and redband trout frequent the creeks into the marsh, and recently, new species of mollusks have been discovered. - The Nature Conservancy
