Air Quality at Grand Teton National Park

What’s in the Air?

Grand Teton NP, Wyoming

Most people who visit national parks expect clean air and clear views. While Grand Teton National Park (NP), Wyoming, experiences relatively good air quality, the park is downwind of significant pollutant sources including power plants, agricultural areas, industry, and oil and gas development. Pollutants emitted from these sources can harm the park’s natural and scenic resources such as surface waters, vegetation, fish, and visibility.

How is air pollution affecting Grand Teton National Park?

  • Levels of nitrogen in wet deposition are increasing and may harm sensitive alpine ecosystems in the park. more »
  • Toxic airborne contaminants including mercury and pesticides deposit in park ecosystems, presenting a potential wildlife and human health concern. more »
  • Ground-level ozone concentrations are relatively low, but plant species known to be very sensitive to ozone are found in the park. more »
  • Fine particles of air pollution sometimes cause haze in the park, affecting how well and how far visitors can see vistas and landmarks. more »

What is the National Park Service doing about air pollution at the park?

  • Monitoring nitrogen, sulfur, ozone, fine particles, and haze, and—for a limited time—toxic air contaminants, to assess status and trends. more »
  • Evaluating the impacts of air pollution on park ecosystems. more »
  • Working with federal, state, and local agencies, industry, and public interest groups to develop strategies to reduce air pollution and protect and restore park resources. The NPS also reviews plans for development that may increase air pollution in national parks. more »
  • Participating in the Climate Friendly Parks Program, increasing use of hybrid vehicles, promoting ”no idling“ of vehicles throughout the park, improving energy conservation measures in park facilities, and reducing snowmobiles in the park. more »
