This paper describes construction of a geographic information system (GIS) database of land use/land cover (LU/LC), results of change analyses and implications for future management of the Ebenezer Creek watershed in Effingham County, Georgia. Aerial photo interpretation and GIS analysis techniques were employed to analyze changes in LU/LC in the basin from 1958 to 1993 to identify trends which might contribute to non-point pollution in Ebenezer Creek. Between 1958 and 1993, the greatest transition in LU/LC in the watershed was the loss of about eleven percent of forested lands, primarily to harvested-new growth, residential and urban uses. Given the apparent sensitivity of the Ebenezer Creek and swamp system, continued transitions from forest to other uses, especially within the creek corridor, are likely to exacerbate existing problems. Study results have been provided to Effingham County planning staff for use in development of stream corridor protection strategies.
