The park is home to some 2,000 to 3,000 elk in summer, and between 800 and 1,000 elk spend the winter within its boundaries. Because of lack of predation, the National Park Service culls around 50 elk each winter. Overgrazing by elk has become a major problem in the park's riparian areas, so much so that the NPS fences them out of many critical wetland habitats to let willows and aspens grow. The program seems to be working, as the deciduous wetland plants thrive within the fencing. Many people think the elk herd is too large, but are reluctant to reintroduce predators because of its proximity to large human populations and ranches.[76]
