In 1999, the federal government listed City of Duvall Chinook salmon and bull trout as threatened under City of Everett the Endangered Species Act. Coho salmon are now City of Gold Bar City of Lake Stevens a species of concern under the Act. In response to City of Marysville these federal listings, the Snohomish Basin Salmon City of Monroe Recovery Forum (Forum) created this Draft Salmon City of North Bend Conservation Plan (plan) to guide protection and City of Seattle restoration of salmon in the Snohomish River basin. City of Snohomish The Forum is a cooperative effort with members City of Snoqualmie representing the variety of perspectives found in the City of Sultan basin, including government, The Tulalip Tribes, Coordinated Diking Council business, recreation, agriculture, the environment, Cross Valley Water District East King County the public, and others. Working together, the Forum Regional Water Association has achieved a high level of consensus and support for King Conservation District the plan. King County King County Agriculture (2) At 1,856 square miles, the Snohomish River basin is King County Citizen the second largest watershed - behind the Skagit River Master Builders Association basin - draining to Puget Sound. The people who live Pilchuck Audubon Society Port of Everett and work in the Snohomish River basin take pride in Recreational Interests their communities that span from the urban areas of Snohomish Conservation District Everett to the rural quality of life that includes small Snohomish County towns, farms, and forestry. They want to protect and Snohomish County Agriculture (2) restore salmon runs that are vital to local culture, Snohomish County Citizen identity, pride, and economic benefit. Snohomish County Public Utility District Snohomish County This plan proposes a scientifically based and feasible Sportsmen’s Association course of action over the next decade to begin Stilly-Snohomish Fisheries Enhancement Task Force recovering local salmon populations. The plan is The Boeing Company based on a careful review of scientific data, historical Town of Granite Falls records, and social and economic considerations. Town of Index It provides clear direction to local governments, The Tulalip Tribes Citizen agencies, interest groups, citizens, and other The Tulalip Tribes interested parties on recovery actions that will be Washington State Department of Fish and Wildlife (ex-offi cio) most beneficial, where they should occur, and when they should happen. June 2004 Draft Snohomish River Basin Salmon Conservation Plan – 1-1 This plan is one part of a regional effort to ultimately recover Chinook salmon populations in Puget Sound, and an important step to keep coho salmon from being listed as a threatened species. ¡ ¡ ¢ ¢ ) ) ! # ( ( § ¨ © % & ¤ ¥ ¦ 1.2 Salmon and Trout in the Snohomish River Basin The Snohomish River basin is one of the primary producers of anadromous salmonids in the Puget Sound region. Historic salmon production, however, is estimated to have been substantially greater than that experienced in recent history. An ecosystem approach to salmon recovery is critical. Watershed processes initiated throughout the river basin strongly influence habitat capacity and conditions downstream. The Forum envisions a multi-species approach to salmon recovery. The Ecological Analysis for Salmonid Conservation (2004) identifies Chinook salmon, bull trout, and coho salmon as proxy species to represent all anadromous 1-2 – Draft Snohomish River Basin Salmon Conservation Plan salmonids in the basin. The Forum assumes that a strategy that addresses these species will adequately address the needs of all anadromous salmonids. To recover Chinook salmon Additional protections may be warranted to protect resident trout across Puget Sound, recovery in populations living upstream of natural barriers. the Snohomish River basin is essential. The sections below summarize the status and recovery actions proposed to address the three proxy species.
