| Abstract: | Spatial data analysis and image processing techniques were used to document changes to forest cover and forested wetlands in the Cache River, AR, watershed. Historical topographic maps, recent topographic maps, and digital satellite imagery were used to determine the magniwde of forest removal. Changes in forest fragmentation were quantified based on the distribution and geometry of forest stands. Between 1935 and 1972, approximately 100,000 ha of forest cover (30 percent of the watershed area) were removed. Little change in forest cover occurred after 1975. Comparisons of forest cover with hydric soils data indicate that, in the lower watershed area, up to 80 percent of the forest removed may have been forested wetlands. |
