This book was released on 2007-12-04 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: In North America, Juniperus woodlands occupy approximately 55 million hectares, an area larger than the state of Texas. This title addresses various aspects of the biology, ecology, and management of Juniperus woodlands and savannas, synthesizing past and current research findings as well as proposed research. The book provides ecologists, land managers, and foresters with a solid foundation in Juniperus ecosystems, enabling them to manage the communities for maximum sustained productivity and diversity.

Available in PDF, EPUB and Kindle. Book excerpt: This document provides managers with a literature synthesis of the historical conditions, current conditions, fire regime condition classes (FRCC), and recommended treatments for the major ecosystems in southern Utah. Sections are by ecosystems and include: 1) coniferous forests (ponderosa pine, mixed conifer, and Engelmann spruce-subalpine fir), 2) aspen, 3) pinyon-juniper, 4) big and black sagebrush, and 5) desert shrubs (creosotebush, blackbrush, and interior chaparral). Southern Utah is at the ecological crossroads for much of the western United States. It contains steep environmental gradients and a broad range of fuels and fire regimes associated with vegetation types representative of the Rocky Mountains, the Great Basin, Northern Arizona and New Mexico, and the Mohave Desert. The Southern Utah Demonstration Area consists of contiguous state and federal lands within the administrative boundaries of the Bureau of Land Management (BLM), Fishlake and Dixie National Forests, National Park Sevice, and State of Utah, roughly encompassing the southern 15 percent of Utah (3.24 million ha). The vegetation types described are similar in species composition, stand structure, and ecologic function, including fire regime to vegetation types found on hundreds of millions of hectares in the 11 western states.

Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.

Download or read book The Great Basin written by Donald Grayson and published by Univ of California Press. This book was released on 2011-04-18 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering a large swath of the American West, the Great Basin, centered in Nevada and including parts of California, Utah, and Oregon, is named for the unusual fact that none of its rivers or streams flow into the sea. This fascinating illustrated journey through deep time is the definitive environmental and human history of this beautiful and little traveled region, home to Death Valley, the Great Salt Lake, Lake Tahoe, and the Bonneville Salt Flats. Donald K. Grayson synthesizes what we now know about the past 25,000 years in the Great Basin—its climate, lakes, glaciers, plants, animals, and peoples—based on information gleaned from the region’s exquisite natural archives in such repositories as lake cores, packrat middens, tree rings, and archaeological sites. A perfect guide for students, scholars, travelers, and general readers alike, the book weaves together history, archaeology, botany, geology, biogeography, and other disciplines into one compelling panorama across a truly unique American landscape.
Download or read book Relationship Between Allometric Variables and Biomass in Western Juniper Juniperus Occidentalis written by Breanna S. Sabin and published by . This book was released on 2009 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tenfold expansion of western juniper (Juniperus occidentalis spp. occidentalis) into the sagebrush steppe has led to the degradation of the economic and ecological potential of these landscapes. Land managers have enacted numerous methods to reduce distributions and densities of these trees. Assessment of above ground juniper biomass, expressed overall as well as in each of four fuel - size classes is useful information to land managers for several reasons. These include: enhance smoke management for prescribed burns, appraise feasibility of locating biomass cogeneration power plants, and extrapolating known nutrient and carbon concentrations contained within juniper to the landscape scale. Two sites were selected within Lake County, OR for this research. Allometric measurements including canopy area, canopy volume, age, height, basal diameter were taken from 129 trees and 56 of these were destructively sampled to obtain biomass of each tree; by size classes as well as over all. Regression statistics were utilized to find the correlation between allometric and biomass measurements. Of the allometric variables measured for this research, canopy volume, canopy area, and basal diameter were the strongest predictors of biomass found, with respective R2 values of 0.88, 0.87, 0.81. The proportion of biomass within each of the four size classes was: 34% for size class 1, 15% for size class 2, 23% for size class 3, and 28% for size class 4. Average biomass for these sites was 2,482 kg/ha for the Fort Rock site and 5,410 kg/ha for the Lakeview site. These models can be used to estimate biomass for co-generation plants, estimate nutrient pools and fuel loads, and predict changes in community biomass based on species or growth form groups.
