A group of environmental professionals and managers with various training and ecological departments in the U.S. Army tour a tank range at the Grafenwoehr Training Area in Bavaria, Germany, June 24, 2014. When tanks and other tracked and wheeled vehicles traverse the ranges, many small patterns are left in the ground which promote an area where several amphibians can flourish. Thirty-three years ago, the U.S. Army started monitoring the conditions of their training areas in Europe. Today, 77 percent of these training lands are designated flora and fauna habitat.
