摘要: Human actions must be well planned and include consideration of their potential influences on water aquatic ecosystems - such is the foundation watershed management. Watersheds are ideal land unit for managing protecting resources health because watersheds integrate physical, biological chemical processes within boundaries. Managed forested tend to have more natural functions better quality than other uses. Land uses with greater amounts soil disturbance permanent reductions in infiltration, as agricultural or urban/developed settings, usually undesirable hydrologic alterations poorer quality. Nonpoint source pollutants resulting from many forestry, agricultural, urban activities controlled by techniques tools known best management practices (BMPs). Best applied managers large-scale landscapes, but they also applicable lives ordinary citizens. Basic BMP principles, controlling duration during construction around home, applying chemicals lawns gardens only at needed rates suitable times, incorporating encourage infiltration rooftop driveway runoff important that anyone can take help protect functions, quality, health.
