Mississippi River Watershed Conservation Programs : ウィキペディア英語版 | Mississippi River Watershed Conservation Programs Conservation programs for the Mississippi River watershed have been designed to protect and preserve it by implementing practices that decrease the harmful effects of development on habitats and to overlook monitoring that helps future planning and management. A main focus is nutrient pollution from agricultural runoff of the nation's soybean, corn and food animal production, and problems relating to sediment and toxins. Conservation programs work with local farmers and producers to decrease excess nutrients because they cause major water quality problems along with hypoxia and loss of habitat. Organizations such as the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force and USDA programs such as the Upper Mississippi River Forestry Partnership and the Mississippi River Basin Healthy Watersheds Initiative contribute to conserving what is left of the Mississippi River watershed. ==Conservation of the Mississippi River== Conservation of the Mississippi River Watershed has become an important issue that many organizations are undertaking because the capacity of the river to remove nutrients from the water is decreasing and the surrounding ecosystems are being diminished. The Mississippi River Basin encompasses 31 U.S. states with an area of 1,837,000 square miles.〔(Mississippi River Facts ), www.nps.gov, July 10, 2009, accessed October 27, 2009.〕 The Mississippi River's capacity to remove nutrients has diminished due to a range of human activities, such as development, taking place along the Mississippi River itself and the streams and tributaries linked to it. The layouts of the river, the floodplains, and the watershed have also been modified using engineering techniques for acres of agriculture fields and urban expansion. With increase of natural prairie land being converted to land for agricultural and urban use, there has been an excess of nutrients that are discharged into the Mississippi River and its adjoining streams.
