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.
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.

Download or read book Biogeochemical Responses to Atmospheric Nitrogen Deposition in Subalpine Ecosystems of the Cascades written by Justin Paul Poinsatte and published by . This book was released on 2017 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examined the influence of snow regime on subalpine ecosystem C and N cycling at Mount Rainier under ambient conditions and in climate change scenarios. Timing of snow release influenced ecosystem C and N storage and loss. Climate change may reduce snow accumulation by up to 80% at Mount Rainier by 2050. Snowpack loss may enhance ecosystem C and N accumulation during the growing season and increase winter N leaching.

Book Synopsis Predicting the effects of atmospheric nitrogen deposition in conifer stands by : B A. Emmett
Download or read book Predicting the effects of atmospheric nitrogen deposition in conifer stands written by B A. Emmett and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The NITREX project, which encompasses seven ecosystem-scale experiments in coniferous forests at the plot or catchment level in northwestern Europe, investigates the effect of atmospheric nitrogen (N) deposition in coniferous forests. The common factor in all of the experiments is the experimentally controlled change in N input over a period of 4-5 years. Results indicate that the status and dynamics of the forest floor are key components in determining the response of forests to altered N inputs. An empirical relationship between the carbon-nitrogen (CIN) ratio of the forest floor and retention of incoming N provides a simply measured tool through which the likely timing and consequences of changes in atmospheric N deposition for fresh waters may be predicted. In the terrestrial ecosystem, a 50% increase in tree growth is observed following the experimental reduction of N and sulfur inputs in a highly N-saturated site, illustrating the damaging effects of acidifying pollutants to tree health in so me locations. Few biotic responses to the experimental treatments were observed in other NITREX sites, but the rapid response of water quality to changes in N deposition, and the link to acidification in sensitive areas, highlight the need for N-emission controls, irrespective of the long-term effects on tree health. The observed changes in ecosystem function in response to the experimental treatments have been considered within the framework of the current critical-load approach and thus contribute to the formulation of environmental policy.
Book Synopsis Partitioning of Atmospheric Nitrogen Under Long-term Reduced Atmospheric Deposition Conditions in a Norway Spruce Forest Ecosystem by : Zhuo Feng
Download or read book Partitioning of Atmospheric Nitrogen Under Long-term Reduced Atmospheric Deposition Conditions in a Norway Spruce Forest Ecosystem written by Zhuo Feng and published by Universitätsverlag Göttingen. This book was released on 2010 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past century, anthropogenic activities have increased N input drastically to terrestrial ecosystems and influenced the global N cycle. Especially temperate forest ecosystems are affected in their productivity, species composition, soil chemistry and water quality. N input to forest ecosystems is retained in trees and soil. Excessive N is leached out or released as gases. The retention of N input in soils is mainly influenced by the stability of soil organic matter (SOM). Many forests in central Europe and North America have been subjected to N saturation, i.e. excessive N appeared as nitrate in the leachate below the rooting zone. Reduction of atmospheric N emission and consequent atmospheric N deposition is proposed to be the only practical long-term solution to improve N-saturated forest ecosystems. However, responses of N-saturated forest ecosystems to reduced atmospheric N deposition have been seldom investigated. In the present study, atmospheric deposition was manipulated through roof constructions below the canopy of a mature Norway spruce forest on the Solling plateau in central Germany. A £^(5)N tracer field and a density fractionation laboratory experiment were conducted in the present study to investigate the influence of long-term reduced atmospheric N deposition on the partitioning of atmospheric N in different forest ecosystem compartments as well as on the partitioning of atmospheric N retained in the soil in different SOM pools.

Book Synopsis Precipitation Partitioning by Vegetation by : John T. Van Stan, II
Download or read book Precipitation Partitioning by Vegetation written by John T. Van Stan, II and published by Springer Nature. This book was released on 2020-01-01 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents research on precipitation partitioning processes in vegetated ecosystems, putting them into a global context. It describes the processes by which meteoric water comes into contact with the vegetation's canopy, typically the first surface contact of precipitation on land. It also discusses how precipitation partitioning by vegetation impacts the amount, patterning, and chemistry of water reaching the surface, as well as the amount and timing of evaporative return to the atmosphere. Although this process has been extensively studied, this is the first review of the global literature on the partitioning of precipitation by forests, shrubs, crops, grasslands and other less-studies plant types. The authors offer global contextualization combined with a detailed discussion of the impacts for the climate and terrestrial ecohydrological systems. As such, this comprehensive overview is a valuable reference tool for a wide range of specialists and students in the fields of geoscience and the environment.
