In Chap. 1, we presented an overview of the processes that occur when acid deposition impinges on a terrestrial ecosystem, and from time to time in our more detailed discussions, we have attempted to summarize again material that would help the reader to understand the significance of the individual processes in terms of the total system. Although a summary at this point is to some degree repetitive, we feel it important to reexamine the total system in the context of the concepts we have developed in the previous chapters. In addition, we are including a final section that points out how our perspective of the system may differ from previously accepted concepts.
