ESA Plan: conservation road map to remove species units (ESU’s) from the ESA T/E list

Biological / listing factor criteria: ESU delisting

Population goals: extinction risk (VSP criteria) Specific actions: population goals/listing factors

achieve recovery

Cost estimates/implementation schedules

Rely on• plans with regulatory rules/actions (BiOp’s, TMDL’s, etc.)• voluntary implementation of other actions

Assessment also indicated

Need improvements in most threat sectors

Improve HABITAT conditions in freshwater and estuary

Reduce impacts of• FLOOD CONTROL / HYDROPOWER• HATCHERY• COMPETITION and PREDATION

Improvements needed to maintain current status• Given limited resources prioritize actions• Adopt a long-term perspective

Page 12: draft  Upper Willamette River  Conservation and Recovery Plan  for Chinook Salmon and Steelhead

Major Strategies and Actions

Flood Control/Hydropower Actions

• Willamette Project BiOp actions, FERC agreements• upstream and downstream passage • temperature control and flow modification• revetments and other physical habitat (mainstem projects)

• FCRPS BiOp actions for estuary impacts

Freshwater Habitat Actions

• ODEQ TMDL Water Quality actions • Best Management Practices, State/Federal guidelines• Voluntary protective and restoration actions

Estuarine Habitat Actions

• NMFS Estuary Recovery Plan

Page 13: draft  Upper Willamette River  Conservation and Recovery Plan  for Chinook Salmon and Steelhead

Major Strategies and Actions (continued)

Hatchery Actions • Reduce hatchery fish on spawning grounds• Examine/reduce predation/competition on juveniles• As conditions improve, re-introduce above barriers• Manage as “wild fish emphasis areas”

Harvest Actions

• Manage current regimes in existing Fishery plans

Other Species Actions

• NMFS Estuary Recovery Plan• Research, Monitoring, and Evaluation for predation impact

in Willamette and subbasins

Page 17: draft  Upper Willamette River  Conservation and Recovery Plan  for Chinook Salmon and Steelhead

Mainstem Willamette River Land Use Management

Strategy: Implement Willamette basin TMDL actions, rural and urban BMP’s, and other land-use actions to address multiple Limiting Factors

Actions include:• Temperature TMDL WQMP actions: increase riparian

vegetation/shade function

• Strengthen/implement BMP’s: reduce inputs/runoff of non-point source of chemicals

• Pesticide/nutrient TMDL WQMP actions: reduce sourcing of runoff from urban, industrial, rural, and agricultural practices

• Promote incentives to private landowners: protect/restore riparian areas and high-quality off-channel habitats not covered by actions in other plans

Page 18: draft  Upper Willamette River  Conservation and Recovery Plan  for Chinook Salmon and Steelhead

Strategy: Implement the suite of Willamette Project BiOp flow and habitat actions to address multiple Limiting Factors

Actions include Willamette Project BiOp: • Revetment modification/reduction and restoration

actions:• improve the amount, complexity, diversity, and connectivity of

riparian, confluence, and off-channel habitats

• Flow actions:• increase occurrence of peak flows to maintain and create

habitat, increased channel complexity and habitat diversity

• meet salmon and steelhead rearing and migration flow targets

Habitat Principals and PrioritiesProtect/enhance viability of multiple listed populations

Protect habitat with these traits • natural production areas (subbasins) (PRODUCTIVITY)• supports major life history strategies (DIVERSITY)• contributes to other viability traits (SPATIAL STRUCTURE)

Enhance/restore habitat and natural processes

• increase life-stage survival (ABUNDANCE), reproductive success, and connectivity

Fix specific habitat limiting factors

• large pay-off to closing viability gaps between current and desired future status

Page 20: draft  Upper Willamette River  Conservation and Recovery Plan  for Chinook Salmon and Steelhead

Mainstem Willamette Habitat Projects Considerations and Discussion

A comprehensive and workable shared vision and strategy?

What to protect and restore?• “Ecosystem Services” the conceptual umbrella for goals?

• What level of functional ecosystem process does this imply?

• Are we all on the same page for priorities and time scales?

A structured framework to accomplish this?

A metric to measure progress accomplishment?• Can projects be scoped large enough to elicit a measurable

response?

Balance of willing opportunities (easements/ acquisitions) and regulations?
