A goat from Prosperity Acres in Sunderland, Maryland, grazes at the Congressional Cemetery in Washington, August 6, 2015. Grazing goats returned to Historic Congressional Cemetery to help clear invasive vines, poison ivy, and other unwanted weeds. The use of goats eliminates the need for harmful herbicides and prevents the invasive species from killing large mature trees in the cemetery's wooded area. REUTERS/Yuri Gripas
