This QR project produced an annual report. Submersed aquatic vegetation (SAV) communities are highly productive ecosystems that provide significant ecological benefits within coastal areas, including support for many important species of fish and wildlife. Despite their critical importance, and loss globally, we lack consistent baseline data on SAV resources across the coastal salinity gradient. This project is part of a larger funded effort which has the overall objectives to document the occurrence and abundance of SAV resources (e.g., coverage, composition, seed resources) within the northern Gulf of Mexico over three years, to quantitatively assess environmental factors affecting SAV spatial and temporal variation,...

Submersed aquatic vegetation (SAV) communities are highly productive ecosystems that provide significant ecological benefits to coastal areas, including essential calories for wintering waterfowl. However, the potential effects of sea-level rise is posing new questions about the future availability of SAV for waterfowl and other coastal wildlife. Of primary concern is the fact that rising seas have the potential to increase salinities in fresh and brackish marshes on the Gulf of Mexico’s coast, changing the distribution and composition of SAV communities, and affecting valuable waterfowl habitat and food resources. Not enough is known about the relationship between salinity and SAV to predict how this important...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
