DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKSince 1946, FAO regularly monitors the world's forests through Global Forest Resources Assessments. The mandate to carry out these assessments stems both from the basic statutes of FAO and the Committee on Forestry (COFO). Divided into nine chapters, the publication covers the following topics: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; progress towards sustainable forest management.

DOWNLOAD EBOOKBiological invasion of native plant communities is a high-priority problem in the field of environmental management. Resource managers, biologists, and all those involved in plant communities must consider ecological interactions when assessing both the effects of plant invasion and the long-term effects of management. Sections of the book cover human perceptions of invading plants, assessment of ecological interactions, direct management, and regulation and advocacy. It also includes an appendix with descriptive data for many of the worst weeds.

DOWNLOAD EBOOKPredicting the effect of climate change on insect populations can be used to estimate the costs and benefits of protecting forests from potential damage. In this report, the authors present an analysis of potential changes in the distribution of spruce budworm (Choristoneura fumiferana Clem.) defoliation under climate change in Ontario. They use an empirical model that relates defoliation to historical bioclimatic variables, and then apply climate change data to this model to predict potential changes in the distribution of defoliation.--Includes text from document.
