Book Description
Natural disturbance regimes are critical to biological diversity. Complex interaction among disturbance processes, such as fire and grazing, promote a mosaic of plant communities that vary in structure and successional stage. Topoedaphic variability, site history, and disturbances contribute to landscape heterogeneity. Traditional grazing management that emphasizes uniform disturbance decreases heterogeneity. Variation in disturbance types and intensities may result in distinctively different post-disturbance communities. Grazing management strategies based on historical disturbances may be capable of promoting grassland biodiversity. Patch-burn grazing management mimics historical fire and grazing interactions. This study compares the results of three management treatments within the mixed grass prairie of Western Oklahoma on plant species diversity. Management treatments are 1) traditional management for the region 2) patch-burn management and 3) ungrazed, unburned management. Plant species richness did not differ between treatments. Significant differences were demonstrated by year, presumably due to differences in precipitation.

Book Description
Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?

Book Description
Grasslands are characterized by recurring disturbances such as fire and grazing occurring against a background of topoedaphic heterogeneity and climatic variability. The result is a complex, multi-scaled disturbance regime, in which fire and grazing often have interactive roles, yet they have usually been studied independently. Relationships between climate, fire and simulated grazing (=mowing) were explored to determine the roles these disturbances play in shaping patterns and processes in southern mixed-grass prairie. A field experiment investigated the potential effects of these disturbances on above and belowground plant productivity, patch dynamics, and soil respiration over a 2-year period characterized by drought (1998) and normal (1999) rainfall. Spring burning and mowing had interactive effects on aboveground net primary production (ANPP). Consistent with published single factor studies, burning without mowing doubled ANPP, whereas mowing in the absence of burning had neutral effects. However, subsequent mowing on burned plots reduced ANPP gains to levels comparable with all unburned plots. Drought reduced ANPP by 22% relative to a normal rainfall year. In contrast to the traditional model of root response to defoliation, burning and mowing each stimulated root length recruitment measured with minirhizotrons. However, subsequent mowing on burned plots did not produce additional root recruitment. Fire and mowing appear to interact by affecting different components of root recruitment (production and mortality, respectively). Root biomass recovered from ingrowth cores were not correlated with minirhizotron results, and responded only to drought, suggesting that methodological differences have contributed to the varied root responses reported in the literature. Drought suppressed soil respiration, diminished soil moisture, and enhanced soil temperature, whereas fire and/or mowing had little effect. Results suggest that any fire or mowing effects on soil respiration in southern mixed-grass prairie may be highly constrained by moisture limitations during dry periods. In summary, patch level response to fire is a pulse of root recruitment followed by increased ANPP, unless subsequent grazing offsets these gains. Grazing alone produces a pulse of root recruitment, perhaps to replace consumed foliage. This study demonstrates the interactive nature of fire and grazing in grasslands, and the perils of single-factor studies.

Book Description
"The book celebrates the beauty of a 2.5-acre restored grassland with lively commentary, vivid descriptions, and striking, detailed photographs of the native plants and animals that inhabit it. The authors describe how they prepared the soil, selected and planted seeds, and dealt with unwanted invasive species and weeds"--

Book Description
This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Book Description
This book brings together scientific evidence and experience relevant to the practical conservation of wild birds. The authors worked with an international group of bird experts and conservationists to develop a global list of interventions that could benefit wild birds. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on birds quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bird conservation actions throughout the world. The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.
