Industrial operations in Alberta, Saskatchewan, Manitoba, and the Northwest Territories release airborne emissions that can injure surrounding forest vegetation. This report describes symptoms of these pollutants and of natural stresses that may appear similar. The industries discussed include natural gas processing plants, oil wells and refineries, oil sand plants, metal mines and smelters, cement plants, potash industry, pulp and paper mills, and agricultural chemical production and application. Nineteen pages of color photographs provide examples of these symptoms on forest vegetation.
