Trip Description:     The exceptional Salmon River Estuary covers approximately 2,000 acres, with a tidal influence reaching to River Mile 4. Sitting in the middle of the United National Biosphere Reserve and Cascade Head Scenic Research Area, the estuary and the Marine Reserve at the mouth of the river are components of the UNESCO Cascade Head Biosphere Reserve. The estuary forms a bay between two basalt headlands - The Nature Conservancy's Cascade Head Preserve to the north, and Camp Westwind's High Meadow to the south.

The estuary salt marshes were diked in 1960 to exclude salt water and create pastureland. Administered by the U.S. Forest Service, the estuary restoration project began in 1978 with the goals of establishing natural processes by rebuilding native plant communities, controlling erosion, and controlling noxious weeds. Dikes and tide-gates were removed, which allowed salt water to return to the marshes, killing pasture vegetation and allowing native salt marsh plants to reclaim the land naturally. Extensive plantings of native shrubs and trees stabilized the marshland perimeters. Recovery and restoration of wetlands that were modified to support an old amusement park and a trailer park were completed by 2011.

We will visit the two largest restoration projects and discuss what was learned about recovery of the native vegetation and the return of juvenile salmon to the estuary and creeks feeding it.
