Conservation maps online. (News & Events).

The Library of Congress offers a new web site, Conservation and Environmental Maps, which provides historic and recent maps of land use and exploration in the United States. These maps will be of great interest to ecologists as they show "changes in the landscape, including natural and man-made features, recreational and wilderness areas, geology, topography, wetland area, vegetation, and wildlife." http:// lcweb2.loc.gov/ammem/gmdhtml/ cnsvhome.html.
