Adult Holding
• Pools, cover, and holding areas close to spawning areas (increase LWD and riparian cover)
• Adequate cool water refuges (deep pools)• Increase LWD and riparian cover• Reduce excess sediment filling pools

Spawning and Incubation
• Reduce road, grazing, upland impacts, bank erosion (fines, temp, DO, scour)
• Restore riparian areas (fines, scour, temp)• Remove channel confinement (scour)

Summer and Winter Rearing
• Restoration that improves/maintains– Temperature– Pools– Cover– Substrate size/embeddedness– Cool water refuge areas (off-channel or ground water)

Conclusions and Key Points• It is important to understand habitat requirements
when planning restoration.• Different restoration actions will address different
habitat requirements.• Target the right life stage and focus on limiting
factors.• Fish typically use the entire watershed, thus
restoration/improvements need to ultimately restore the watershed.

Conclusions and Key Points• Document approach for identifying current
conditions and improvements due to restoration.• Acknowledge limitations of approach(es) used.• For long-term recovery need to couple short-term
habitat improvement with long-term restoration.
