  • Factors affecting water clarity vary in different areas of the estuary and have impacted underwater grasses recovery.
  • Sea-level rise and land subsidence will continue to cause losses and landward migration of tidal wetlands during the coming century.
  • The abnormalities in fish have been strongly linked with a variety of contaminants.
  • Declines in seaduck populations could be from changes in diversity and abundance of shellfish and other benthic foods.
  • Summary of findings and implications for habitats and fish and bird populations.

Document the Status of and Changes to the Health of Fish, Wildlife, and their Critical Habitats

The health of fish, wildlife, and their supporting habitats in the Bay and its watershed has been degraded due to multiple causes, including poor water quality, disease, invasive species, and over harvesting. The Chesapeake Bay Program has worked to improve conditions for living resources and habitat and the Watershed Agreement strategy outlines specific goals to sustain fish and wildlife and recover habitats.

The USGS is working with the U.S. Fish and Wildlife Service and other partners to research and monitor the many factors that contribute to the poor health of fish, wildlife, and their habitats so that more effective management practices can be implemented in the coastal areas of the Chesapeake Bay and its watershed.
