Description    


Columbia Land Trust used this funding to restore and protect 183 acres of intertidal emergent and forested wetlands along the Grays River, in the Columbia River estuary in Wahkiakum County. The Grays River supports the largest population of chum in the Columbia River. The wetlands that this project restored and protected are critical to the early life history of coho, Chinook, and chum salmon as well as steelhead and sea-run cutthroat trout. The project addressed the following limiting factors: floodplain connectivity, large woody debris, riparian condition, and water quality. This project conserved and restored floodplain habitat by restoring hydrologic access to Seal Slough; breaching a levee in three locations; connecting tidal channels; filling drainage ditches; introducing large woody debris; and planting spruce, willow and other native species. The result of this project is 183 acres of productive intertidal wetlands for nursery areas, forest canopy regeneration, connection of Grays River and Seal Slough, and improved estuarine function.
As of amendment #5, the scope of this project additionally includes 1,200 feet of levee removal along the Grays River; 80 acres of reed canarygrass control; and 16,000 feet of tidal channel excavation and no longer included removal of the tidegates and direct connectivity to Seal Slough.

Project Benefit    


The goal of the project is to protect and connect isolated habitat to increase the range and distribution of salmon. The objective of the project is to protect and increase access to tidelands and shorelines.
