        <Desc>The Brandywine Conservancy (the Conservancy) works for preservation and wise management of natural, historic, and scenic resources of the Brandywine Valley and surrounding areas with particular and strong emphasis on the preservation of land, water supplies and agriculture. Through this program, the Conservancy acquires conservation easements on open spaces and often on historic lands and, as of this filing, has 514 easements which are regularly monitored to assure landowner's compliance with the restrictions in each easement. The program aids municipal governments in the region on environmental issues such as storm water management, ordinances of various types affecting land and water resources, and land use planning. The Conservancy owns more than 3,009 acres of land which it carefully manages to help preserve land and water resources and to serve as models of high standards in the stewardship of natural and agricultural lands.</Desc>
