Aquatic habitat is sensitive to streamflow, so the USGS is assessing how climate change can affect land cover and flow in river systems. The project team will experiment with a variety of resolutions for linking hydrology and landcover data for analyzing streams in the Apalachicola-Chattahoochee-Flint watershed to improve the ability to detect and project the condition of aquatic habitats. Decision makers will be consulted to determine priority species so that speciesspecific models can be developed and used to assess the vulnerability of fishes and mussels to climate change. This project is a part of the Southeast Regional Assessment Project (SERAP).
