Abstract

    In 1987, in response to concerns about the impacts of atmospheric deposition, commonly referred to as “acid rain,” on forest ecosystems, the US Environmental Protection Agency (EPA) provided funds for the establishment of Bear Brook Watershed Research Site, Maine (BBWM), as a Watershed Manipulation Project (WMP) under the National Acid Precipitation Assessment Program (NAPAP). BBWM was established to identify atmospheric deposition impacts on surface waters and to quantify the major processes controlling surface water acidification under increased sulfur (S) and nitrogen (N) atmospheric deposition.
