UNESCO Cascade Head Biosphere Region

This 102,110-acre site was designated as a Biosphere Region in 1976 on the central Oregon Coast by the United Nations Man and Biosphere Program and reauthorized in 2017. This rare and diverse ecosystem includes the Salmon River and its estuary, a sandy littoral spit, densely forested uplands, a two-mile basalt headland covered in native coastal prairie, and a marine reserve stretching west into the waters of the Pacific.

This unique land/sea connection is protected and managed by a dynamic community of agencies, non-profits, businesses, and residents in the surrounding communities.

A Diverse Ecosystem

• Seven miles of Pacific Ocean coastline with a recently added marine reserve and major coastal prairie headlands jutting out to sea. A littoral sand spit, dune, and beach pine complex.
• The Salmon River, and its recently restored estuary, providing critical staging areas for upstream spawning migrations of anadromous fish and rearing areas for juveniles and smolts.
• A community of several thousand humans living in both rural and city environments.

Additional federal and state designations

• A Nature Conservancy preserve (entire headland)
• A federal Scenic Research Area (estuary and river)
• A National Forest under late-successional reserve management
• A State Marine Reserve
• State held Conservation easement (Westwind)
