[Beyond Pesticides, August 8, 2013] — Over 100 goats have been tasked with controlling poison ivy, ground cover, vines and other invasive weeds at the Congressional Cemetery this week. The Association for the Preservation of The Historic Congressional Cemetery partnered with Eco-Goats to control the invasive species that threaten large mature trees, which can fall and damage headstones. In addition to their weed-managing services, the goats provide free fertilizer, aerate the soil with their hooves, and eliminate the need for chemicals. The goats, penned outside of the burial area of nearly 200 members of Congress, J. Edgar Hoover and other notable Washingtonians, will graze 24 hours a day for the next several days to control weeds along the perimeter of the cemetery. At a press event held Wednesday at the cemetery, Paul Williams, president of the Association explained that the goats are being used as an eco-friendly and cost-efficient alternative to machines or pesticide, considering the cemetery rests on the banks of the Anacostia River.
