Petrified Forest National Park AQRV's
Petrified Forest NP has no surface waters.
While there have been no systematic studies, there is currently no information indicating that wildlife in Petrified Forest NP are being affected by air pollutants.
Dark night skies are considered an important air quality related value at Petrified Forest NP, possessing value as a cultural, scenic, natural, and scientific resource. Air pollution and poor quality outdoor lighting degrade night skies, lessening a viewer's ability to see stars and other astronomical objects, and altering the nocturnal scene. Use of high quality lighting that produces very little scattered light can greatly improve the night sky. Reduction of haze from air pollution can also improve the night sky.
Soils in Petrified Forest NP are likely to be well-buffered and insensitive to acidification from atmospheric deposition. There is no information available on the effects (e.g., fertilization) of nitrogen deposition on soils in the park. In some parts of the country, nitrogen deposition has caused changes in soil nutrient cycling.
Several plant species that occur in Petrified Forest NP are known to be sensitive to ozone (e.g., Rhus trilobata) although the specific genotypes found in the park have not been tested under controlled conditions for sensitivity. These species are sensitive AQRVs.
