Summary

Airborne pollutants like sulfur dioxide, fluoride, and ozone harm North American forests. These toxic gases cause visible injury, reduced growth, and increased tree mortality, impacting various species locally and regionally.

Area of Science:

  • Forestry
  • Environmental Science
  • Plant Pathology

Background:

  • Airborne phytotoxic pollutants negatively impact forest tree health across North America.
  • Local exposure to pollutants like sulfur dioxide and fluoride causes foliar injury, dieback, and mortality.
  • Regional air pollutants, particularly ozone, contribute to growth decline in sensitive pine species.

Purpose of the Study:

  • To summarize the adverse effects of airborne phytotoxic pollutants on forest tree growth.
  • To highlight the varying impacts of pollutants on different scales (local vs. regional).
  • To discuss the complex etiology of forest decline, including pollutants and other factors.

Main Methods:

  • Review of existing literature on air pollution impacts on North American forests.
  • Analysis of observed effects at local and regional scales.
  • Identification of key pollutants and affected tree species.

Main Results:

  • Sulphur dioxide and fluoride cause direct foliar injury and mortality in various tree species.
  • Ozone is linked to growth decline in eastern white pine, ponderosa pine, and Jeffrey pine.
  • Forest declines in red spruce and sugar maple likely involve a combination of factors, including air pollution.

Conclusions:

  • Airborne pollutants are a significant threat to forest health in North America.
  • Understanding pollutant impacts is crucial for forest management and conservation.
  • Further research is needed to fully elucidate the complex causes of forest decline.
