III) V) Addition of new focal species.
IV) Development of population targets with demographic parameters for each focal species in each bioregion (and watersheds if possible) Develop of long-term assessment monitoring programs (with reference sites) in each bioregion of CA
Restoration recommendations from the Central Valley A) Maintain patchy and varied age strucuture
1. High water events will contribute to structural diversity resembling that of structurally diverse riparian systems, and provide more heterogeneous nesting habitat. 2. Regeneration of habitat mosaics.
3. May reduce populations of nest predators. Cosumnes River levee break

Evaluate efficacy of riparian restoration on Sacramento River
Step 1 Identify issues
Restore functioning riparian ecosystem with meander that supports self-sustaining and diverse songbird populations
Step2 Set biological goals
12 steps for implementing assessment monitoring
Breeding and migrating land bird diversity will increase with current restoration efforts (both process-based and horticultural).
Step3 Develop specific biological objectives
Standardized bird surveys and vegetation information and nest monitoring performed
Step 4 and 5 collect and store data
Revise
Integrate with other conservation and management plans and stimulate research Results suggest increase shrub cover is associated with species diversity and may increase nest success Increase shrub species in planting mix and increase scouring by removing levees
Step 7 and 8 Implementation Step6 Generate result Step 11 and 12
New data and multi-year analysis of nest data suggest that nest success increases with amount of mugwort and rush cover.
Add mugwort and rush to planting mix Bird surveys and nest monitoring continue.
Step9 continue data collection Step 10 repeat
