莫农加赫拉国家森林所在的大西洋中部地区的酸性沉积率是全国最高的。由于大量的酸性投入和公众对这一问题的日益关注，森林正在其目前的森林计划修订中处理这一主题，因为它涉及到对水质、水生生境、土壤养分状况和森林生产力的潜在影响。计划修订工作已完成约50%，修订小组目前正处于设计多层次监测计划的初始阶段，以收集和汇编数据，以评估持续沉积和土地管理活动对土壤和水资源的短期和长期影响。本文简要描述了酸沉积对土地生产力影响的科学现状，以及它们对莫农加赫拉地区的管理意义。此外，还介绍了对森林的风险评估分析以及继续收集数据和扩大数据库的监测战略。提供了Monongahela国家森林对酸性输入和盐基阳离子损失高度敏感的流域的初步土壤化学数据，以说明将这一问题纳入森林计划修订和项目一级规划的重要性，并说明该小组如何将现有数据纳入其决策过程。
The mid-Atlantic region, in which the Monongahela National Forest lies, receives some of the highest rates of acidic deposition in the country. As a result of the substantial acidic inputs and growing public concern with the problem, the forest is addressing this topic in its current forest plan revision as it relates to potential effects to water quality, aquatic habitat, soil nutrient status, and forest productivity. Plan revision is approximately fifty percent complete, and the revision team is now in the initial stages of designing a multi-level monitoring plan to collect and compile data to evaluate shortand long-term effects of continued deposition and land management activities on soil and water resources. This paper briefly describes the state of the science of acidic deposition effects on land productivity, and their management implications for the Monongahela. Additionally, risk assessment analyses for the forest and monitoring strategies to continue data collection and database expansion are described. Preliminary soil chemistry data from watersheds highly sensitive to acidic inputs and base cation loss on the Monongahela National Forest are presented to illustrate the importance of including this problem in forest plan revision and project level planning, and to show how the team incorporated available data in its decision processes.
