Even though the land base is only about 450 acres, the area covers over 300 square miles. The Refuge supports a marine bird breeding population of twelve species estimated at 108,000 breeding pairs. Bald eagles and peregrine falcons also nest on the islands. The Refuges also support various other wildlife. Northern sea lions, California sea lions and harbor seals regularly haul out on the rocks and reefs.
River otters are resident on some islands, and sea otters use the surrounding kelp beds.
Some larger, vegetated islands also support isolated populations of Townsend's voles, Trowbridge's shrews, shrew-moles, garter snakes and salamanders. Work Outdoors at GORP Jobs Click Here. All rights reserved.
