Overview

September 2002
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.
2. Regeneration of habitat mosaics.
3. May reduce populations
of nest predators.

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
Integrate with
other
conservation
and
management
plans and
stimulate
research
Revise
Standardized bird surveys and
vegetation information and
nest monitoring performed
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
12 steps for
implementing
assessment
monitoring
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.
Increase shrub species in planting
mix and increase scouring by
removing levees
Add mugwort and rush to planting mix
Step 10 repeat
Step 7 and 8 Implementation
Bird surveys and nest monitoring
continue.
Step9 continue data collection
