The Cache River Wetlands Joint Venture Partnership is a collaboration among governmental entities and non-profit organizations. It is composed of Ducks Unlimited, Illinois Department of Natural Resources, Natural Resource Conservation Service, The Nature Conservancy and U.S. Fish and Wildlife Service. Its goal is to protect and restore a corridor along of the Cache River. ==Conservation focus== Currently, the partnership is working on three areas: restoring forest and wetland habitats, reducing sediment and eroding streams, and exploring ways to restore low water flow to the lower segment of the Cache River, which was disconnected from the upper stretch of the river in the early 1900s. * Restoring Habitat—Forest and wetland restoration restores function to a river’s floodplain, increases habitat for wildlife and reduces sediment entering the river. * Reducing Sediment—Sediment enters the Cache many ways, which is why efforts to reduce it have taken many different forms. Efforts include working with landowners to use conservation tillage and constructing strategically located flow retention ponds. From 1987 to 1995, for example, erosion on more than in the Cache River Watershed was reduced by more than 1 million tons annually. * Restoring Low Water Flow—The Cache, like other rivers, needs free-flowing water to be healthy. A gentle current brings oxygen and dissolved nutrients, while also moving pollutants out of the system. Research currently underway is trying to determine ways this might be accomplished. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cache River Wetlands Joint Venture Partnership」の詳細全文を読む スポンサード リンク
