The Cascade Head Biosphere Region is a 102,110 acre site designated originally in 1976 on the central Oregon Coast by the United Nations Man and Biosphere Program and reauthorized to our current footprint in 2017. Our 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.
