Résumé :
|
Riparian (streamside) ecosystems have been the subject of ecosystem research for about the last twenty years. Ecosystem research has shown that riparian areas are especially effective controllers of nitrogen and sediment movement to streams and other water bodies. Nitrogen control is primarily the result of biotic processes. Sediment control is primarily caused by physical processes that are enhanced by such biotic interactions as enhanced infiltration and leaf litter at the soil surface. Riparian areas are increasingly being used as a landscape- and watershed-management technique to reduce the risk of pollution and to create and preserve healthy stream ecosystems. The management practices recommended for riparian areas are based on ecosystem research. Riparian ecosystem policies and management are a success story for the application of ecosystem science to real-world problems. Riparian ecosystem research has been used to develop generalized management practices for USDA action agencies such as the Natural Resources Conservation Service and the Forest Service.
