Humboldt Bay National Wildlife Refuge is located on

black brant. Humboldt Bay National Wildlife Refuge, along with other public and private lands around Humboldt Bay, is one of the key stopovers for the millions of migratory birds that rely on the Pacific Flyway. More than 200 bird species, including 80 kinds of water birds and four endangered species

, regularly feed, rest, or nest on the refuge or other areas around the bay.

Ecology

The bay provides habitat for approximately 100 species of fish, many of which contribute to sport or commercial fisheries, and provides habitat for fish including

brant goose prior to their return to Arctic nesting grounds; and the refuge grasslands provide important habitat for thousands of Aleutian cackling geese. Like many of the refuges in the system, this one was established to preserve habitats recognized to be instrumental to the perpetual survival of migratory birds and other wildlife. Each spring, over 20,000 Aleutian cackling geese roost on the island from late January through early April. Castle Rock National Wildlife Refuge also serves as a haul out for resting marine mammals including harbor seal, northern elephant seal, California sea lion, and Steller sea lion

.

Humboldt National Wildlife Refuge Complex

The refuge is the largest part of the Humboldt National Wildlife Refuge Complex, which is headquartered south of Eureka at its Loleta, California site. The "Complex" is an administrative entity that also manages the Lanphere Dunes Unit and the Castle Rock National Wildlife Refuge. Lanphere Dunes, located on the northern seaward shore of Humboldt Bay, contains the most pristine remaining dune ecosystem in the Pacific Northwest and supports rare and representative examples of older forested dunes, young active dunes, dune swale wetlands, and coastal salt marsh. Castle Rock National Wildlife Refuge is a 14-acre (57,000 m²) island located 80 miles (130 km) north of Humboldt Bay (less than 1-mile (1.6 km) off the Pacific Coast) near Crescent City. The island serves as the second-largest seabird nesting colony in California. Castle Rock Refuge has the largest breeding population of common murres in California.
