520 3 a| A method to provide a broad-scale assessment of watershed condition was developed to determine potential effects on stream nutrient export. Land cover/land use (LCLU) and stream buffer width and length were the variables used to calculate potential nitrogen export (PNE). The study was conducted using GIS and remote sensing on the headwaters of Little Contentnea Creek on the eastern North Carolina coastal plain. A land cover classification was performed and nitrogen export coefficients were applied to forest and agriculture land cover types to estimate PNEs from the watershed. Riparian areas of 30 m, 10.7 m, and 4.6 m width (each side) were placed around the stream network using GIS, and cover type was identified as forested, half-forested, or imforested. The width and length of the forested and half-forested types were used to calculate reductions in PNE due to the capacity of these areas to remove nitrogen, based on literature values. Comparisons were made between these existing watershed PNE amounts and the maximum PNE for the watershed, which assumed LCLU of 100% agriculture with 0% forested buffers, to obtain a general idea of the condition of the watershed in terms of N exports. Scenarios of different LCLUs and buffer lengths and widths were developed to address PNE reductions and/or buffer restoration strategies, and to estimate the effects of land use changes within a watershed or its riparian zones. The 30% annual N load reduction goals of the Neuse River Agriculture Rule were also addressed using these scenarios. An important factor in PNE reduction was the presence of forested riparian buffers. While buffer width is an important factor in reducing the PNE from a watershed, it was also clear that the length of forested buffer adjacent to the stream was critical in PNE reduction and must be considered in the assessment of watershed condition.;

Summary	A method to provide a broad-scale assessment of watershed condition was developed to determine potential effects on stream nutrient export. Land cover/land use (LCLU) and stream buffer width and length were the variables used to calculate potential nitrogen export (PNE). The study was conducted using GIS and remote sensing on the headwaters of Little Contentnea Creek on the eastern North Carolina coastal plain. A land cover classification was performed and nitrogen export coefficients were applied to forest and agriculture land cover types to estimate PNEs from the watershed. Riparian areas of 30 m, 10.7 m, and 4.6 m width (each side) were placed around the stream network using GIS, and cover type was identified as forested, half-forested, or imforested. The width and length of the forested and half-forested types were used to calculate reductions in PNE due to the capacity of these areas to remove nitrogen, based on literature values. Comparisons were made between these existing watershed PNE amounts and the maximum PNE for the watershed, which assumed LCLU of 100% agriculture with 0% forested buffers, to obtain a general idea of the condition of the watershed in terms of N exports.
