Résumé :
|
Fish habitat of the Edisto River basin in South Carolina was evaluated using a Geographic Information System (GIS). A committee of fisheries biologists was formed to evaluate fish habitat within the basin, and the GIS was used to compile and analyze data and generate maps to represent quality of fish habitat. United States geological Survey (USGS) 1:24,000-scale digital line gaph (DLG) hydrography data were assigned values for data on species composition, predesignated protected areas, riparian habitat, dams and impoundments, ditches and channelization, and water quality. Each criteria was assigned a point value, and these values were totaled and subdivided into Value Classes 1, 2 and 3 representing high, moderate, and low quality fish habitat, respectively. Greater than 75% of the 11,000 km of basin streams contained good fish habitat.
