Fifty-six focal species
Over 220 specific multi-species recommendations in California PIF Bird Conservation Plans
Recommendation 3.6:Plant a minimum of 3 tree species including willow, alder, and elderberry in Central Valley and foothill riparian habitats.
Species Benefited:Black-headed GrosbeakLazuli BuntingSpotted TowheeWestern KingbirdWestern Wood Pewee
Recommendation 4.1:Restore and manage riparian forests to promote structural diversity and high volume of the understory.

California Partners in FlightOverview
I) Test recommendations in other bioregions and conditions.
II) Disseminate recommendations.III) Addition of new focal species.IV) Development of population targets with
demographic parameters for each focal species in each bioregion (and watersheds if possible)
V) 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.
3. May reduce populationsof nest predators.
Cosumnes River levee break
2. Regeneration of habitat mosaics.

Dissemination and Integration• Workshop that include BCP recommendations.
– NRCS Wetland Restoration, Management and Compatible Use.
– State agencies ‘Legacy Program’– With stakeholders and watershed groups.
• Joint Projects– Central Valley Joint Venture– NRCS Conservation Reserve and Enhancement Program
• Funding (project ranking)– US Forest Service Charter– San Francisco Bay Joint Venture Creeks Comm.– RHJV project selection criteria.– NAWCA– Endangered species Act ?

Standardized bird surveys and vegetation information and nest monitoring performed
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 mixIncrease shrub species in planting mix and increase scouring by
removing levees
Bird surveys and nest monitoring continue.
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
Breeding and migrating land bird diversity will increase with current restoration efforts (both process-based and
horticultural).
Step3 Develop specific biological objectives
Step 4 and 5 collect and store data
Results suggest increase shrub cover is associated with species diversity and
may increase nest success
Step6 Generate result
Step 7 and 8 Implementation
Step9 continue data collection
Step 10 repeat
Integrate with other
conservation and
management plans and stimulate research
