RESEARCH/MONITORING NEEDS (source(s) of needs)
NOTE: See Recovery Plan
for additional research/monitoring needs.
Monitoring
- Priority
monitoring action – Conduct species-specific surveys (PIF Monitoring
Needs doc)
- Second
priority monitoring action – Conduct Mexican species-specific
surveys (PIF Monitoring Needs doc)
- Predict
abundance and distribution of BCVI habitat based on current and future
expected land use practices (TARP -
Edwards
Plateau
)
Habitat Needs/Ecology/Life History
- Determine
reasons for BCVI occupation of a relatively constrained habitat series
(BNA)
Effects of Management Practices
- How
does browsing on oak shrublands affect the long-term viability of
habitat as relates to BCVI? (TARP
-
Edwards
Plateau
)
Effects of Human Development/Disturbance
- What
are the effects of hiking and/or biking trails on nesting BCVI?
Tolerance levels? Trail
width? (TARP -
Edwards
Plateau
)
Landscape
- See
needs under “Distribution of populations…”
Species Interactions
- What
other priority species co-occur with BCVI and how do their densities
& reproductive success vary with management for BCVI? (Osage
Plains)
Wintering
- Define
wintering habitat for BCVI, as well as information on social &
foraging behavior (BNA)
Demographics
- Establish
values of basic population parameters, especially juvenile
survivorship & dispersal (BNA)
Genetics/Taxonomy/Systematics
- Answer
questions about population genetics of BCVI (BNA)
