Nason Creek Salmon Habitat Conditions* Development, and road building have affected riparian (streamside) habitat, large woody debris and gravel recruitment (trees and rocks), and limit channel movement. Water temperatures may limit salmon recovery (Lower Nason Creek is on State 303(d) list for water temperature). *Paraphrased from the Upper Columbia Salmon Recovery Board’s Biological Strategy (22 May 2003)

Salmon Recovery In Nason Creek* Enhance Riparian Habitat: Improve riparian habitat using native riparian vegetation Reduce road density Install livestock exclusion fencing and upland watering stations Protect Riparian Habitat: Condition development to be consistent with state or local regulations or permits Prohibit sand and gravel removal in inappropriate areas Avoid or mitigate impacts of upland development where it could impact channel conditions Establish and protect riparian buffers using regulatory and incentive mechanisms Acquire priority riparian areas through: –purchase; –conservation easements; and/or; –transfer/purchase of timber, farm, grazing or land development rights Provide incentives and compensation to landowners to retain buffers. Continue public information and outreach efforts to educate and inform citizens *Paraphrased from the Upper Columbia Salmon Recovery Board’s Biological Strategy (22 May 2003)

Salmon Recovery In Nason Creek* Enhance Channel Movement: Increase stream sinuosity and decrease entrenchment (meander reconstruction) Add LWD in the form of rootwads, log jams, and similar structures that mimic natural formations Decommission, modify, or relocate roads, low- priority dikes, bridges and culverts Protect Channel Movement: Uphold existing land use and instream work regulations that limit riparian area, floodplain and wetland development Educate the public on the importance of stream channel movement Allow stream channels to develop and flood naturally Manage stormwater runoff from existing and new development and road construction using detention, treatment and infiltration measures *Paraphrased from the Upper Columbia Salmon Recovery Board’s Biological Strategy (22 May 2003)

Salmon Recovery In Nason Creek* Water temperatures may limit salmon recovery. Establish and protect riparian buffers Implement Total Maximum Daily Loads that address temperature Restore river features such as pool-riffle sequences, meander bends, backwaters, and side Fence livestock out of riparian areas; Manage stormwater runoff from existing and new roads and developments using appropriate measures Decrease the stream width-to-depth ratio Decommission, modify, or relocate roads, low- priority dikes, bridges and culverts Improve upland water infiltration through road decommissioning, reduced soil compaction, direct seeding activities, increasing native vegetation cover, CRP participation, etc. Enhance the extent and function of wetlands and wet meadows. Enhance spring inputs to streams Improve natural stream form and function. *Paraphrased from the Upper Columbia Salmon Recovery Board’s Biological Strategy (22 May 2003)
