DESCRIPTION
The Lower Klickitat River Riparian Re-Vegetation Project (Phase 1) will restore native riparian and floodplain vegetation (cottonwood, alder, and willow) between river miles 2.6 and 18.3 of the Klickitat River. This reach is a migration and rearing corridor for nearly 100% of all migratory fish in the Klickitat watershed and has accounted, on average, for 10% of observed basin-wide steelhead spawning. The goal of this project is to improve riparian and floodplain vegetation to increase bank cover, woody debris recruitment, and potential for trapping fine sediment. The project area occurs within a reach identified as the third highest of 21 top priority geographic areas in the "Klickitat Lead Entity Region Salmon Recovery Strategy".
Riparian conditions in this reach are generally poor due to a combination of the 1996 flood deposits and channel encroachment by highway and road fill. Many of the flood deposits are well above the two-year flood surface and at a comparable elevation to surfaces that are well-vegetated and are generally stable. Vegetation has been very slow in colonizing these coarse, well-drained substrates. Similar deposits from flooding in 1974 along Swale Creek (a Klickitat River tributary) are still bare. This project addresses limiting features and functions (poor riparian and floodplain vegetation) identified in the "Klickitat Lead Entity Region Salmon Recovery Strategy" for the project reach. Phase I activities will occur on seven sites and total 6.9 acres with 1.45 miles of stream bank.
