Otter Rock Marine Reserve, located off the central Oregon coast near the town of Otter Rock, is Oregon’s smallest marine reserve, encompassing a mere 1.2 square miles. Despite its size, this protected area offers a unique glimpse into the diverse marine ecosystems of the Pacific Northwest.
Within the reserve, all taking of animals and seaweeds is prohibited, as is any ocean development. This protection ensures the natural environment thrives undisturbed.
Discovering the Unique Features of Otter Rock
Seafloor Habitat Map for Otter Rock Marine Reserve
A Peek Beneath the Waves: The northern part of Otter Rock Marine Reserve boasts extensive rocky intertidal habitats along the shoreline. These areas, exposed during low tides and submerged during high tides, teem with life. Mussels, sea stars, anemones, chitons, and various seaweeds are common inhabitants. Below the surface, the reserve features a shallow rocky reef, kelp forests, soft-bottom habitats, and sand dollar beds, providing shelter and sustenance for a wide array of marine species.
Experiencing Otter Rock from Land: Visitors can access the reserve through Devils Punchbowl State Natural Area. Exploring tidepools, observing seals basking on rocks, and strolling along the sandy shores of nearby Beverly Beach State Park are popular activities. Remember to practice respectful wildlife viewing etiquette to protect these sensitive environments and their inhabitants. Three offshore islands define the western boundary of the reserve, adding to the scenic beauty. Nearby coastal towns include Depoe Bay, Otter Rock, and Newport.
Planning Your Otter Rock Adventure: This area offers more than just marine life viewing. Hiking trails and scenic viewpoints abound. Consult local activity guides for detailed information and plan your perfect Otter Rock adventure.

The Importance of Design and Placement at Otter Rock
The Oregon Department of Fish and Wildlife (ODFW) Marine Reserves Program employs specific monitoring techniques tailored to each reserve’s unique characteristics, including size, habitat, depth, and historical fishing activity.
Otter Rock’s small size, shallow depth, limited subtidal rock habitat, and historically low fishing pressure mean observable changes directly attributable to marine reserve protections may be subtle.
Monitoring Strategies: Despite the anticipated minimal changes compared to fished areas, long-term data collection at Otter Rock is crucial. Sampling both inside and outside the reserve (at Cape Foulweather) allows scientists to track changes in marine communities over time. This data helps resource managers understand broader trends in Oregon’s nearshore ocean environment.
A Living Laboratory: Otter Rock serves as a valuable training ground for scientists. Volunteer divers, ODFW staff, and Oregon State University researchers utilize the reserve for training, pilot studies, and juvenile fish settlement research, contributing to our understanding of nearshore ecosystems.
