The deer population in Valley Forge Park was cut in half (approximately) when the herd was reduced by sharpshooters starting in November. Estimates put the deer herd in the park at 1,277 animals. The eventual goal is the have less than 200 deer in the park.
Despite lawsuits from animal rights activists, the culling was carried out over sixteen nights starting in November 2010. The overabundance of deer was damaging the forest growth and crowding out other animal species in the park.
