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)
- Develop
a conservative estimate of GCWA population size (TARP -
Edwards
Plateau
)
- Identify
current and optimum distribution of protected habitats for GCWA (BNA)
Habitat Needs/Ecology/Life History
- What
are the differences in habitat use by GCWA in various parts of its
range? (TARP -
Edwards
Plateau
)
- Further
studies of ecology/behavior (including foraging behavior & prey
species, movements w/in populations and during postbreeding,
distribution in relation to productivity) (BNA)
- Habitat
needs on breeding grounds (BNA)
Effects of Management Practices
- How
does browsing on oak-juniper woodlands affect the long-term viability
of habitat for GCWA? (TARP
-
Edwards
Plateau
)
Effects of Human Development/Disturbance
- Predict
habitat for GCWA in 10, 20, 50, and 100 years based on predicted human
population growth & development in c. TX (TARP -
Edwards
Plateau
)
- What
is the effect of hiking and/or biking trails on nesting GCWA?
Tolerance limits? Trail
width? (TARP -
Edwards
Plateau
)
- Effects
of urbanization on GCWA (BNA)
Landscape
- Effects
of habitat fragmentation on GCWA (BNA)
Predation
- Effects
of predators on GCWA (BNA)
Nest Parasitism
- Effects
of nest parasites on GCWA (BNA)
Migration
- GCWA
biology, behavior and habitat needs during migration (BNA)
Wintering
- GCWA
biology, behavior, and habitat needs on winter grounds (BNA)
- What
are the threats to GCWA on its wintering ground?
Is habitat being destroyed there at a similar rate to its
U.S.
breeding habitat? (TARP -
Edwards
Plateau
)
Demographics
- Research
on population biology (survivorship, dispersal, reproductive success,
population sizes needed to maintain viability, gene flow between
populations) (BNA)
