Development has siphoned away and polluted water. Uniforms, guns, swords, saddles and photographs suffer from mold and rust. Too many visitors and vehicles, air pollution and air tour overflights. Air pollution has reduced visibility and damaged plants. Nearby airport expansion will bring more non-native species and undermine the biodiversity.
Nearby development threatens the park's character.
The park's tranquillity is routinely disrupted by the noisy intrusion of motorized vehicles. A crumbling sewage system has caused spills into Yellowstone Lake and near Old Faithful. The sun could set on a popular program that has protected and restored Wisconsin's natural areas since 1989 unless people call their legislators and push for its renewal, says the Wisconsin Stewardship Network. The State Stewardship Fund has restored wildlife and fish habitat, improved water quality and expanded opportunities for outdoor recreation through its funding of land acquisition projects in environmentally sensitive areas, but the program is scheduled to end in fiscal year 1999-2000. Since 1989, thousands of acres of land have been purchased through the fund for state recreation areas.
