- Habitat loss, degradation and fragmentation within the Chesapeake Bay watershed
- Habitat loss, degradation and fragmentation at other ends of the Atlantic Flyway population’s range
- Food availability (which is affected by competition and proximity to developed or otherwise disturbed lands)
- Shoreline disturbance (e.g., due to dredging or development)
- Pressure from invasive species
- Pressure from climate change (including sea level rise, floods, salinity changes and salt marsh migration, large storms and shifts in migration patterns or wintering range)
Factors Influencing Progress
Several factors could impact our ability to restore, enhance and preserve wetland habitat to support a wintering population of 100,000 black ducks. These factors have directly informed the management actions our partners will take to achieve the Black Duck outcome.
