Understanding the effects of management practices, soil organisms and soil properties on carbon sequestration and biodiversity conservation was the main focus of the research projects presented in this dissertation. I measured and compared carbon pools and processes in two important grassland ecosystems of the Palouse region of southeastern Washington and northern Idaho: native prairie remnants and Conservation Reserve Program (CRP) set-asides. I found that carbon inputs were similar between prairie and CRP grasslands. However, root biomass and soil carbon concentrations were higher in prairie remnants. These results demonstrate that processes and carbon inputs in CRP sites have reached similar levels to native prairies, but belowground carbon pools are still larger in prairie remnants. The results suggest that efforts to promote carbon sequestration in these grasslands should be focused on increasing belowground carbon. I also characterized earthworm populations in native prairie remnants and CRP set-asides. I found that earthworm populations were composed mostly of European exotic earthworms in both grassland types and dominated by the exotic earthworm Aporrectodea trapezoides. A single specimen of the native earthworm, Driloleirus americanus was found at a prairie remnant. The results suggest that conservation priorities for native earthworms in the Palouse need to focus on habitat description, conservation and possibly restoration. Additionally, I measured the effect of the exotic-invasive earthworm Aporrectodea trapezoides on carbon dynamics using a microcosm experiment. I found that the presence of A. trapezoides did not have an effect on plant productivity, and that its main impact on carbon dynamics was through the formation of soil macroaggregates. These macroaggregates can physically protect carbon against mineralization. An additional collaborative study aimed at describing soil and site correlations with Palouse prairie plant communities confirmed that aspect and vegetation structure were significant predictors of plant species richness (R2 = 0.15) and plant diversity (R2 = 0.13). These results may help set research and biological conservation priorities for isolated and un-inventoried prairie remnants.

In 2002, the USDA Agricultural Research Service (ARS) developed a coordinated national research effort called GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) to provide information on the soil C status and GHG emission of current agricultural practices, and to develop new management practices to reduce net GHG emission and increase soil C sequestration primarily from soil management. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet project in over 30 ARS locations throughout the US and in numerous peer-reviewed articles. Although GRACEnet is an ARS project, contributors to this work include a variety of backgrounds and reported findings have important international applications. For example, many parts of the world possess similar ecoregions to the U.S. (e.g., northern Great Plains is similar to the Argentina Pampas and Ukraine Steppe).

This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.

Grazing lands represent the largest and most diverse land resource-taking up over half the earth's land surface. The large area grazing land occupies, its diversity of climates and soils, and the potential to improve its use and productivity all contribute to its importance for sequestering C and mitigating the greenhouse effect and other condition
