Download or read book Insects and Diseases of Mediterranean Forest Systems written by Timothy D. Paine and published by Springer. This book was released on 2016-01-06 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect and disease issues are often specific to the Mediterranean forest systems rather than shared with the temperate forests. In addition to the specific native insects and diseases, the forests are subject to the invasion of exotic species. The forests are also at risk from high degrees of human activity, including changing patterns of forest fires, land management activities, intensive plantation forestry using introduced timber species from other Mediterranean climate zones, and atmospheric deposition. Combined with elements of global climate change that may disproportionately affect Mediterranean climate systems, this creates a number of significant management issues that are unique to the Mediterranean forests. It is our goal that the information contained in this volume will contribute to understanding the unique aspects of Mediterranean forest systems and to protecting these critical resources.
Download or read book Bark Beetles written by Fernando E. Vega and published by Academic Press. This book was released on 2014-12-29 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bark Beetles: Biology and Ecology of Native and Invasive Species provides a thorough discussion of these economically important pests of coniferous and broadleaf trees and their importance in agriculture. It is the first book in the market solely dedicated to this important group of insects, and contains 15 chapters on natural history and ecology, morphology, taxonomy and phylogenetics, evolution and diversity, population dynamics, resistance, symbiotic associations, natural enemies, climate change, management strategies, economics, and politics, with some chapters exclusively devoted to some of the most economically important bark beetle genera, including Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus. This text is ideal for entomology and forestry courses, and is aimed at scientists, faculty members, forest managers, practitioners of biological control of insect pests, mycologists interested in bark beetle-fungal associations, and students in the disciplines of entomology, ecology, and forestry. - Provides the only synthesis of the literature on bark beetles - Features chapters exclusively devoted to some of the most economically important bark beetle genera, such as Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus - Includes copious color illustrations and photographs that further enhance the content

Download or read book The Western Bark Beetle Research Group written by and published by . This book was released on 2009 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The compilation of papers in this proceedings is based on a symposium sponsored by the Insect and Diseases Working Group (D5) at the 2007 Society of American Foresters (SAF) convention in Portland, Oregon. The selection of topics parallels the research priorities of the Western Bark Beetle Research Group (WBBRG) (USDA Forest Service, Research and Development), which had been recently formed at the time of the symposium. Reflecting a unique partnership within the Forest Service, each paper was jointly prepared by a research scientist with the WBBRG and one or more entomologists with Forest Health Protection (USDA Forest Service, State and Private Forestry). Among these papers is a description of the currently elevated impacts of bark beetles in the Western United States; descriptions of the current state of knowledge of bark beetle response to vegetation management and also to climate change; discussions of the complex interactions of bark beetles and fire and of the complex ecological and socioeconomic impacts of infestations; an overview of the use of semiochemical (behavioral chemicals)-based technology for conifer protection; and a case study exemplifying efforts to assess risks posed by nonnative invasive bark beetles." --
Download or read book Forest Reference Conditions for Ecosystem Management in the Sacramento Mountains New Mexico written by and published by . This book was released on 1998 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the history of land use and historic vegetation conditions on the Sacramento Ranger District of the Lincoln National Forest within the framework of an ecosystem needs assessment. We reconstruct forest vegetation conditions and ecosystem processes for the period immediately before Anglo-American settlement using General Land Office survey records, historic studies and accounts, and reconstructive studies such as dendrochronological histories of fire and insect outbreak and studies of old growth. Intensive grazing, clearcut logging, fire suppression, and agriculture in riparian areas have radically altered forest structure and processes since the 1880s, when intensive settlement began in the Sacramento Mountains. Present forests are younger and more dense than historic ones, and in areas that were previously dominated by ponderosa pine, dominance has shifted to Douglas-fir and white fir in the absence of frequent surface fire. Landscapes are more homogeneous and contiguous than historic ones, facilitating large-scale, intense disturbances such as insect outbreaks and crown fires.
