Riparian Restoration - IMW Study Area
|
The Asotin Co Conservation District propose to complete a riparian restoration plan on 17 km of Asotin Creek and its tributaries and plant ~ 8.9 km of the highest priority acres. The stream supports wild steelhead and is located within the Asotin Creek Intensively Monitored Watershed (IMW). The project focuses on 3 tributaries in the upper watershed: Charley, North Fk Asotin & South Fk Asotin. The primary limiting factor identified in the IMW is limited riparian function (e.g., temperature, habitat quantity and quality). The goal of other restoration work being conducted in the IMW is to improve riparian function by increasing channel-floodplain connectivity. This project supports that goal by speeding the recovery of a more natural and native vegetation community as riparian conditions improve. The focus areas will be the lower 8 km of Charley, the lower 3 km of North Fk Asotin, and 6 km of South Fk Asotin. This project will identify priority riparian planting areas, develop a riparian restoration plan, and promote long-term riparian function by controlling weeds and planting native tree species. Target tree species include Douglas-fir, ponderosa pine, and cottonwood that achieve a large enough size that, when they fall into the stream or floodplain area, have the ability to influence channel dynamics and increase the diversity of habitats available for all freshwater life stages of steelhead and other fish species using Asotin Creek. This is the final phase of the IMW Restoration.
