Book Synopsis Air Pollution and Its Impacts on U.S. National Parks by : Timothy J. Sullivan
Download or read book Air Pollution and Its Impacts on U.S. National Parks written by Timothy J. Sullivan and published by CRC Press. This book was released on 2017-02-03 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

Book Synopsis Assessment of Atmospheric Nitrogen and Sulfur Deposition Critical Loads for Aquatic and Terrestrial Resources on National Forest System Lands in the Intermountain Region by :
Download or read book Assessment of Atmospheric Nitrogen and Sulfur Deposition Critical Loads for Aquatic and Terrestrial Resources on National Forest System Lands in the Intermountain Region written by and published by . This book was released on 2021 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical load (CL) is a science-based threshold that identifies the amount of pollutant deposition below which no significant ecological harm to an ecosystem component is expected. This report provides baseline critical load (CL) analyses for nitrogen (N) and sulfur (S) as required under the 2012 Planning Rule for forest plan assessments. The data also can be used to inform land management decisions where the effects of N and S deposition are relevant, including the evaluation of large projects through the National Environmental Policy Act, Prevention of Significant Deterioration (PSD) permitting program, wilderness monitoring, and watershed condition. Significant portions of the USDA Forest Service system lands in the Intermountain Region are exposed to N deposition levels that exceed CLs. Areas in exceedance have an increased risk of negative ecological effects. Nine of the 12 National Forests within the Intermountain Region have areas that exceed CLs for surface water acidification and therefore are at higher risk for declines in abundance and diversity of aquatic species. All 12 National Forests have areas that exceed CLs for surface water eutrophication, lichen species richness, forage lichen abundance, and tree species growth rate and probability of survival (over 10 years). In areas with increased risk of surface water eutrophication, competitive interactions and community structure of primary producers can shift and cause compounding effects within the food web. Diversity and abundance of key aquatic species may decrease to the point of extirpation. Areas that exceed CLs for lichen species richness and forage lichen abundance have an increased risk to experience reduced diversity, occurrence, and abundance of lichen species which can negatively affect other biota such as mammals, birds, and invertebrates, that rely on lichens for food, shelter, and camouflage. Areas with an increased risk for declines in tree growth rate and probability of survival may experience a change in the composition of forest communities.

Book Synopsis Approaches for Estimating Critical Loads of Nitrogen and Sulfur Deposition for Forest Ecosystems on U.S. Federal Lands by : Linda H. Pardo
Download or read book Approaches for Estimating Critical Loads of Nitrogen and Sulfur Deposition for Forest Ecosystems on U.S. Federal Lands written by Linda H. Pardo and published by . This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Projected emissions of sulfur and nitrogen are expected to have continuing negative impacts on forests, in spite of reductions in sulfur emissions as a result of SO2 control programs. Sulfur and nitrogen emissions present serious long-term threats to forest health and productivity in the United States. This report is intended to explain the differences in approaches for calculating critical loads for forest ecosystems in Europe, Canada, and the United States; it is directed to air quality regulators and Federal Land Managers (FLMs) in the United States, and addresses concerns particular to U.S. Federal lands. The paper describes the basic mass balance approach for calculating critical loads, presents the various critical thresholds, and explains the assumptions inherent in the calculation and data selection procedure. The input necessary from FLMs in the process of estimating the critical load is described.
