Abstract T he condition of and potential threats to a given wetland are often largely determined by surrounding land use. Land use, especially the percent of the watershed that has been cleared of natural vegetation, can affect the amount of water, sediment, pesticide, and nutrients entering a wetland as well as the composition of its plant and animal communities. A rapid and inexpensive assessment of the land use around a wetland and its implications for nutrient and sediment inputs can be made using readily available maps and aerial photographs, including county soil maps, USGS quadrangle maps, land-use maps, and aerial photographs. These are used to delimit the watershed or drainage basin around a wetland and to classify land use within this watershed. These land use data are used to calculate an index of potential nutrient loading to the wetland and a sediment risk index. Their intended use is to identify quickly, easily, and cheaply those wetlands that are at greatest risk from nutrient and/or sediment inputs.
