South Slough National Estuarine Research Reserve, National estuarine research reserve in Charleston, Oregon.
South Slough National Estuarine Research Reserve is a protected area spanning over 4700 acres with forests, salt marshes, mudflats, and water channels along the Coos Bay estuary. The landscape shows how freshwater and saltwater meet to create a complex environment that shifts with the tides.
The reserve was established in 1974 as the nation's first National Estuarine Research Reserve, marking a turning point in coastal protection. Since then it has been managed by Oregon State Lands and has served as a model for similar reserves across the country.
The reserve occupies traditional lands of the Miluk Coos people, who developed deep ties to these waters and coastal regions over many generations. Visitors can sense this historical relationship with the land through how the site is managed and protected today.
The site has multiple hiking trails and water access points where visitors can explore the landscape. An on-site visitor center provides information and educational programs to help you understand the coastal ecosystems.
The site contains Valino Island and extensive eelgrass beds that form rare habitats in the estuary. These underwater areas are difficult to reach but are crucial to how the place functions ecologically.
