Air Quality at Redwood National Park

What’s in the Air?

Map of Redwood National Park in California
Redwood NP, California

Most people who visit national parks expect clean air and clear views. Redwood National Park (NP), California, home to the world’s tallest trees, is upwind from many pollution sources and therefore experiences relatively good air quality. However, airborne pollutants from nearby logging and mining operations, wood smoke, vehicles, power plants, and agriculture have the potential to harm the park’s natural and scenic resources such as surface waters, vegetation, and visibility.

How is air pollution affecting Redwood National Park?

  • Redwood trees thrive on naturally-occurring coastal fog that often makes it difficult to capture the perfect photo. Additionally, fine particles of air pollution from human-caused sources can cause haze in the park, affecting how well and how far visitors can see vistas and landmarks. more »
  • Levels of nitrogen and sulfur deposition are relatively low, but, forest lichens and streams may be sensitive to nitrogen eutrophication (enrichment) and acifification. more »
  • Estimated ground-level ozone concentrations are relatively low, but plant species known to be very sensitive to ozone are found in the park. more »

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

  • Monitoring fine particles and haze to assess status and trends in visibility. 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 »
  • Using more fuel efficient vehicles, upgrading lighting options to include efficient fixtures, improving energy conservation measures in park facilities, and increasing awareness among park staff, visitors, and the local community.
