Air Quality Monitoring - Rocky Mountain National Park

Seminal research conducted by the National Park Service shows that air pollution is creating acid rain and damaging the park ecosystem.

Research shows that air pollution levels are 60% higher than the ecosystem can sustain. This means that the park is already becoming uninhabitable for wild plants and aquatic species. Twenty years of air and water samples are showing:

  • Species are less diverse in mountain lakes and streams because of increasing nitrogen levels in rain that falls to the ground, acidifying streams and soils
  • A shift from wildflowers to grasses
  • High concentrations of ground-level ozone
  • Poor visibility caused by air pollution


  • Exhaust from cars and trucks
  • Emissions from manufacturing operations that produce the goods and services we use
  • Emissions from coal-fired power plants that produce electricity
  • Dust containing nitrogen from farm activities like fertilizing and livestock operations

What You Can Do
