Description

Abstract: The Salmon River estuary, on the central Oregon coast, provides an excellent opportunity to study salmonid use of restored tidal marsh. The U.S. Forest Service manages the estuary as part of the Cascade Head Scenic Research Area with the goal to rehabilitate the estuary “to its condition prior to the existing diking and agricultural use.” To achieve this goal, the U.S. Forest Service has completed three dike removal projects at 9-year intervals beginning in 1978. These projects created a patchwork of restored marshes in various stages of recovery, providing a natural laboratory for studying marsh restoration processes and their effects on estuarine rearing salmonids. Our Sea Grant-funded research, which is a cooperative study with researchers from the University of Washington, has four objectives: (1) describe salmon species use of undiked reference and recovering marshes; (2) compare diets of juvenile salmon among reference and diked marshes of different recovery ages; (3) compare availability and distribution of prey organisms consumed by juvenile salmon; and (4) assess geomorphological and ecological indicators (“metrics”) of restored wetlands and relationships to salmon use. This report describes the results of fish distribution and abundance surveys. Results of the other objectives are described in Gray et al. (In Review).
