Acid Deposition: Characterizing the Current Condition of Wilderness The rugged alpine and subalpine wilderness areas of our western mountains are one of America's great natural treasures. While the very survival of such ecosystems in some of the most inhospitable of natural environments testifies to their ruggedness, they are actually quite fragile in terms of their ability to withstand potential damage associated with human-caused pollution
. Protecting and enhancing America's forests and rangelands : 1986 research accomplishments. Forests and forestry United States; Rangelands United States. Acid Deposition: Characterizing the Current Condition of Wilderness The rugged alpine and subalpine wilderness areas of our western mountains are one of America's great natural treasures. While the very survival of such ecosystems in some of the most inhospitable of natural environments testifies to their ruggedness, they are actually quite fragile in terms of their ability to withstand potential damage associated with human-caused pollution. Those pollutants, carried to the wildernesses by the atmosphere, consist of a wide variety of potentially damaging chemicals. Because the materials of concern are carried by the atmosphere and deposited on the ecosystems, scientists term the phenomena "atmospheric ; The most worrisome class of pollutants is the ones that are acid. They are deposited dry (in particles) and wet (incorporated in falling rain and snow and in fog and frost). Rocky Mountain Station scientists and their cooperators have developed new techniques for characterizing the effects of air pollution on wilderness ecosystems. They have also developed protocols for consistent description of the current conditions of the subject ecosystems. Included are measures to quantify the atmospheric environment, soil and geology, aquatic chemistry, and aquatic and terrestrial biota. Now, for the first time, a wide variety of scientific investigators and other interested parties will have a set of consistent standards on which to base future work. Many years of research lay ahead to determine specific cause-and-effeet dose-response relationships between specific pollutants and individual ecosystem effects, but this protocol establishment effort will provide a firm scientifc foundation for those years of This device collects cloud water for measuring atmospheric deposition in wilderness areas
