Humboldt County
Humboldt Bay National Wildlife Refuge



Humboldt Bay National Wildlife Refuge is located in Humboldt Bay near the city of Eureka in Northern California. It is composed of several separate units including the pristine Lanphere & Male'l Dunes and Castle Rock Island to the north of Eureka, as well as two adjacent units - Hookton Slough & Salmon Creek - in the main complex south of the city. All told there are about 4,000 acres in the HBNWR complex. The bay itself is, of course, the principal attraction for the wildlife and the eel grass in the wetlands is one of the more important specific flora in the general area. The area is home to 316 species of birds, 40 species of mammals, and approximately 100 species of fish and marine invertebrates. Private land adjacent to the refuge is also used by wildlife of all kinds. There are also a number of other locales in the general region that contribute to the conservation efforts of the refuge. (See Arcata Marsh and Samoa Dunes as examples.) Access to Castle Rock is prohibited, but there are good walking trails in both Hookton Slough and Salmon Creek as well as some restricted access to Lanphere and Male'l Dunes. The Refuge headquarters is located in the Hookton Slough unit and the U.S. Fish & Wildlife Service staff there are very helpful to visitors.
