Forest Management

Forest management includes a range of human interventions that affect forest ecosystems. These activities include both conservation and economic activities, such as extraction of timber, planting and replanting of various species, cutting roads and pathways through forests, and techniques for preventing or making outbreaks of fire. In developed countries, the environment has increased public awareness of natural resource policy, including forest management. As a direct result, primary concerns regarding forest management have shifted from the extraction of timber to other forest resources including wildlife, watershed management, and recreation. This shift in public values has also caused many in the public to mistrust resource management professionals. This book presents the latest research in this field. Lifestock refers to any animal breed kept by humans for commercial purposes. This book focuses on the effects of certain types of foods, such as prebiotics, on the physiology and performance of animals. Research is included on the digestibility and the nitrogen balance of diets containing different protein sources. A review of the effect of polyphenolics on animal productivity and health is also given, as well as a review of models based on milk fatty acid patterns to predict nutrient supply, methane emission, and metabolic disorders. Related to this, the Greenhouse Gas emissions from a Canadian dairy industry is examined. Finally, lifestock diseases compromise animal welfare, reduce productivity and in some cases, infect humans. A review on how to monitor a number of infectious diseases that are of particular economic importance to the dairy cattle industry are discussed. Disease management is also reviewed.
