• To encourage habitat for indigenous species of plants and animals. <br /> • To create approximately 30 acres of new seasonal marsh habitat in the eastern part of <br /> South Tracy Lake. <br /> • To provide habitat for waterbirds, migratory birds, and threatened or endangered <br /> species. <br /> • To manage marsh habitats in a manner that will not result in mosquito problems. <br /> • To develop a monitoring program, to be implemented by a competent biologist over a 5 <br /> year period, to insure that the above objectives are met. Specifically, the monitoring <br /> program will document that the water level management is providing proper inundation <br /> of the mitigation site; that the site has developed the targeted plant communities, <br /> including associated invertebrates; and that the site supports migratory waterfowl, <br /> shorebirds, and other wildlife. <br /> Restoration Considerations <br /> Seasonal wetland development is dependent upon access to water, appropriate soil <br /> conditions, and topography. At Tracy Lakes, water is available from natural runoff within <br /> the Jahant Slough watershed. In times of drought, water is also available from wells. Soil <br /> .r <br /> conditions at the refuge that facilitate wetland development include a generally high water <br /> t <br /> table (during winter runoff) and the natural ability of the soils to hold water(e.g., high clay <br /> content or the presence of a hardpan). <br /> Seasonal wetlands will be managed for a diversity of habitats and wildlife, including <br /> waterfowl and shorebirds, upland and associated flora and fauna, as well as endangered <br /> species. Wetlands strategies will be both passive, (e.g., with little human input) and active <br /> (e.g., through intensive water management strategies appropriate for developing plant <br /> communities and dependent wildlife).
