Cape Perpetua Marine Reserve
Discover the Natural Wonders of Oregon’s Ocean
The rocky shores of the marine reserve and North MPA host some of the most biologically diverse rocky intertidal habitats found anywhere in the Pacific Northwest. Underwater, the reserve and MPAs are dominated by sand and gravel habitats. The site also features a deep, isolated rocky reef home to a wide diversity of groundfish and invertebrates. Upwelling, followed by periods of relaxation, create highly productive waters around the Cape Perpetua area.
The Cape Perpetua Marine Reserve is Oregon’s largest marine reserve. The site is located off the central Oregon coast stretching between the towns of Yachats and Florence. The site includes a marine reserve, two Marine Protected Areas (MPAs), and a Seabird Protection Area.

What Makes Cape Perpetua Unique
Beneath the Surface
The rocky shores of the marine reserve and North MPA host some of the most biologically diverse rocky intertidal habitats found anywhere in the Pacific Northwest. Underwater, the reserve and MPAs are dominated by sand and gravel habitats. The site also features a deep, isolated rocky reef home to a wide diversity of groundfish and invertebrates. Upwelling, followed by periods of relaxation, create highly productive waters around the Cape Perpetua area. These waters are also known to experience episodes of hypoxia (low oxygen) and acidification (low pH).

Design & Placement Matter
The ODFW Marine Reserves Program uses different monitoring tools tailored to each of Oregon’s marine reserves based on the reserve’s size, habitats, depths, prior fishing activities, and other unique characteristics of each reserve.
The Cape Perpetua Marine Reserve has a deep, isolated rocky reef — which is unique to this area as sand and gravel habitats tend to dominate in this region. There is no rocky reef habitat at a similar depth, with similar oceanographic conditions and fishing pressure, anywhere in the nearby vicinity.
Sampling Approach For this marine reserve we are looking at how this isolated, rocky reef marine community changes through time. We’re also looking at how these trajectories of change inside the reserve compare to other, shallower rocky reef habitats in nearby areas outside of the reserve over time.
Long-term Monitoring Hotspot The rocky intertidal habitats in the Cape Perpetua Marine Reserve are a hotspot of biodiversity. Scientists from Oregon State University (OSU) and PISCO have been monitoring the dynamics and intertidal species here for decades. In addition, scientists from OSU, PISCO, and ODFW have been conducting oceanography, hypoxia, and ocean acidification studies in this area since the early 2000s.
Monitoring Activities
ODFW uses the the following tools and sampling intervals to monitor the reserve at Cape Perpetua based on the site’s unique characteristics.
In addition to these activities, their Partners at OSU, PISCO, and ODFW’s Marine Habitat Project are conducting rocky intertidal surveys, hypoxia-ecology studies, and oceanographic surveys at the site.
