Excerpt from Range and Pasture Management There remains now the big economic problem of revegetating the pasture and of maintaining such a nutritious forage cover as will be consistent with a maximum use of the lands. For the accomplishment of this, three things are necessary. There should be maintained at all times an effective plant cover which will bind the soil firmly and so preserve it against erosion and other destructive agencies. It is also necessary to determine which are the most important forage plants, as well as the objectionable pasture species, and how the desirable forage types may most expediently be improved. Furthermore, the foraging animals should be handled in such a way as to secure the largest percentage of offspring and of marketable stock consistent with economical production.

Excerpt from Annotated Bibliography of Publications From the San Joaquin Experimental Range Many problems of the annual-type ranges are related to wise and efficient use of the vegetation. Research projects con-p ducted at the San Joaquin Experimental Range have been and are designed to furnish solutions to these problems. Early range management research at the Experimental Range was directed toward determination of grazing capacity and effects of different intensities and seasons of grazing upon the condition of the range. Erosion and precipitation runoff studies were also conducted during the early years. Nursery and other seeding trials were made with annual and perennial range plants from all over the world. More recently range management re search has centered on range improved by sulfur fertilization. Conversion of brush to grass has been studied. Recommendations have been developed for crushing, burning, and spraying brush to reduce or remove plant competition and allow an increase in de sirable range herbage production. Research involving livestock has been concerned with increasing beef production through larger calf crops, improved nutrition, and reduced losses from poisonous plants, animal diseases, and other factors. This has required many studies throughout the broad field of livestock production. The abundance of wildlife in the area has prompted zo ologists to conduct intensive studies at the Experimental Range. Competition for range forage between rodents and livestock has formed the basis of some work. Various ecological relationships between species of wildlife have formed the basis of other studies. Game species such as the valley quail have been the subject of research efforts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Cheatgrass (Bromus tectorum) is an exotic species that appeared in North America in the late nineteenth century and has since become a dominant plant in the arid and semiarid rangelands between the Sierra Nevadas, Cascades, and Rocky Mountains. It is the first grass to appear after the region's long, cold winters and thus has become an important forage plant for livestock and wildlife. Cheatgrass is also a major environmental hazard in the sagebrush plant communities where it has established itself, providing highly combustible fuel for the wildfires that have ravaged so much of the Great Basin since the mid-twentieth century. Cheatgrass is the first comprehensive study of this highly invasive plant that has changed the ecology of millions of acres of western rangeland. Authors Young and Clements have researched the biology and impact of cheatgrass for four decades. Their book addresses the subject from several perspectives: the history of the invasion; the origins and biology of cheatgrass; its genetic variations, breeding systems, and patterns of distribution; its impact on grazing management; and the role it plays, both positive and negative, in the lives of high desert wildlife.

Management of Agricultural, Forestry and Fisheries Enterprises theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Growing populations and expectations have placed extreme pressure on agricultural, forestry and fisheries resources. Sustainability of resources and resource industries will be achieved only with commitment, ingenuity and cooperation at unprecedented scale. The theme on Management of Agricultural, Forestry and Fisheries Enterprises begins with an assessment of the organization of agricultural, forestry, fisheries and rural enterprises introducing community-based management, traditional small farms, cooperatives and marketing boards, collective and state enterprises, and integrated global corporate systems. This is followed by thorough assessments of management systems for plants, livestock, forests and fisheries. Plant management systems are based on genetic resources, water management, nutrient management and agronomic systems. Livestock production systems are considered from the standpoints of genetic resources, range and pasture-based systems, landless systems, and options for diversification. Trends in the forest industry are revealed in terms of demand for a variety of products from forests, evolving policy regimens and sylvicultural developments. The final topic addresses the complex issues surrounding sustainability of the world's fisheries. This theme assess the evolving state of the main resource industries interpreting trends and identifying challenges and opportunities. Contributors have attempted to project these developments and raise questions about their impact and role in a changing world. Clearly, they are part of an unfolding story of adaptation of the resource industries in an increasingly global society. These two volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.
