A forest ecosystem covering 26 square miles was exposed to anhydrous ammonia following a pipeline rupture in June, 1971. Initial effects included death or defoliation of vegetation and high nitrate accumulations in plant tissues, soils, and natural waters. Deciduous trees and herbaceous species had recovered one year after exposure and soil and water conditions were near normal, but Pinus echinata and Juniperous virginiana showed loss of needles, abnormal twig growth and low cone production after three years. Ammonia or ammonium hydroxide entered plants primarily through stomates and caused injury by desiccation, nutritional imbalances, and other alterations in cell conditions.
