low precision)
RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Improve the Breeding Bird Survey (BBS) (PIF
Monitoring Needs doc)
- Second
priority monitoring action – Conduct early spring surveys (PIF
Monitoring Needs doc)
- Supplemental
WHWO Surveys
- Continue periodic species-specific assessment of Canadian WHWO
populations (Canadian Action Plan); Inventory WHWO distribution
(Oregon/Washington)
- Delineate
WHWO metapopulations (BNA)
Habitat
Needs/Ecology/Life History
- Study
WHWO nesting ecology and habitat use (Oregon/Washington)
- Study
the natural history of WHWO (minimum population size, source
populations, minimum patch size, etc.) (
Nevada
)
- Conservation
Biology
- Research on basic conservation biology (Canadian Action Plan); More
research on conservation biology (especially populations north of
California
) (BNA)
Effects
of Management Practices
- Silvicultural
Practices
- Identify treatment conditions that attract WHWO (Oregon/Washington);
Determine if an intensively harvested landscape can support viable
populations of WHWO (Oregon/Washington); Determine effects of changing
forest tree species composition, stand age, & stature on WHWO
populations (BNA)
Landscape
- Define
the area requirements and landscape patterns for area sensitive
species including WHWO (Oregon/Washingtgon)
Demographics
- More
information on demographics (reproductive success) of WHWO (BNA)
Genetics/Taxonomy/Systematics
- Genetic
variation in WHWO
- Information on genetic differentiation of sedentary populations in
isolated mountain ranges (especially s
California
) (BNA); Conduct a rangewide assessment of geographical variation
inWHWO population genetics and relation to named subspecies (BNA)
