TRANSCRIPT
Lower Columbia River and Columbia River Estuary Habitat Restoration Program
• Mission of the Estuary Partnership is to protect and enhance the lower Columbia River and estuary ecosystem
• Comprehensive Conservation and Management Plan (CCMP) has series of actions directed at habitat protection and restoration
• This project will result in a coordinated, science-based habitat restoration program coordinated jointly by CREST and LCREP
Problem
• Loss of habitat identified as greatest threat to the integrity of lower river and estuary
• Diking, filling, shoreline armoring, dams, and urban development altered the river landscape
• Physical complexity such as shallow, dendritic channels and backwater sloughs diminished

Historic Habitat Loss
• Juvenile salmonids need a complexity and a continuum of habitats for feeding, resting, and refuge
• Suitable lower river and estuary habitats are crucial to survival of subyearling chinook salmon listed under the ESA
Importance to Salmonids
Connection to Other Initiatives
• NWPPC subbasin planning
• Channel deepening
• Oregon and Washington salmon restoration programs
• BiOp RPA 159: “...develop a plan addressing habitat needs of salmon and steelhead in the estuary”
• BiOp RPA 160: “...develop and implement an estuary restoration program…”
Building on Existing Processes
• Estuary Partnership, in coordination with CREST and the Science Work Group, has established a foundation for a cooperative, consensus-based approach to ecosystem restoration in the estuary
• Good, productive working relationships with organizations currently involved in habitat restoration – CREST, Ducks Unlimited, Columbia Land Trust, USFW, Sea Resources, LCFRB, the Corps, etc.
The process has resulted in the following four significant accomplishments:
1. Maps -- Developing comprehensive habitat maps of lower river that can be used for planning purposes
2. Workshop -- Held a workshop on habitat conservation and restoration projects in the Lower Columbia River and Estuary -- Astoria June 12-13, 2001
3. Project Prioritization -- Developed a list of projects through the Science Work Group that meet the habitat criteria and are acceptable to all parties and agreed to work cooperatively to seek funding for these projects in the short term (Objective 2 below)
4. Strategic Approach -- Agreed to develop a strategic approach to protect and restore habitat in the lower river and estuary that is holistic in nature and based on sound science
Project Proposal
• Building on work completed to date, the project would institutionalize the habitat restoration program for the lower Columbia River and estuary and implement six habitat restoration projects identified by the Science Work Group.
• Thus, the project has two main objectives.
Objective 1: Establish a comprehensive, coordinated habitat
restoration program
• 1.1 Refine and expand the habitat restoration program envisioned in the CCMP and developed thus far by the Science Work Group
• 1.2 Develop program management infrastructure
• 1.3 Select projects
• 1.4 Develop project implementation guidelines• 1.5 Oversee implementation, monitor, evaluate, and
report results
Objective 2: Implement six priority habitat restoration projects
• West Sand Island – Restore tidal action to emergent wetland– 10 acres - $726,000– Status: ready to go
• Skipanon Slough– Return tidal flows to normal conditions– 30 acres - $300,000– Status: ready to go
• Grays Bay– Restore tidal flows and forest/marsh
communities, protect remaining spruce wetlands
– 1000 acres - $4,000,000– Status: Land acquisition and dike removal
• Channel Islands– Protect natural habitat and wetland restoration– 1,700 acres - $3,400,000– Status: Land acquisition, separate grant request
to acquire Crims Island
• Scappoose Bay Lowlands– Improve natural hydrology and restore natural
flows– 1,500 acres - $3,700,000– Status: Land acquisition
• Rooster Rock– Improve hydrology– 200 acres - $250,000– Status: nearly ready to go
Expected Products
• Program plan and management infrastructure
• Revised project selection-prioritization criteria
• Guidelines on habitat restoration
• Program M&E plan• Annual and quarterly
progress reports• 3 habitat projects
implemented and 3 developed
