Download or read book Direct Control of Western Pine Beetle (Dendroctonus Brevicomis LeConte) written by Richard H. Smith and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 70 years of research and application are reviewed and assessed. Results of direct control projects can be characterized as generally effective, temporary, quite variable, and unpredictable in reducing subsequent tree mortality. Some causes of this characterization are variable and difficult stand conditions and logistics, lack of good beetle population measurements and prediction, unknown attributes of tree and stand dynamics and of beetle population dynamics, and unforeseen post-application factors. The control method used did not appreciably change this characterization: fell-peel-bum, salvage logging, penetrating oil, residual toxic sprays, or attractive pheromones. Use of attractive pheromones was never thoroughly analyzed, and use of baited toxic trap trees was never adequately tested; both should be done.

Download or read book Surveying Marbled Murrelets at Inland Forested Sites written by and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marbled murrelet (Brachyramphus marmoratus), a seabird, nests in forested stands from southeast Alaska south to Santa Cruz, California. Because of this species' close association with old-growth forests, researchers and land managers need a method to assess murrelet distribution and use patterns throughout its range. This guide describes a standardized method for surveying marbled murrelets used by researchers in California and Oregon during 1988 and 1989. Transects can be used to assess activity patterns over large blocks of land, such as States or counties. Stationary counts using an intensive inventory method can be used to survey small acreages, such as individual timber sales. In addition to bird counts, vegetation and physical data should be collected at each census point. The guide includes a form that can be used to design studies and determine activity patterns and potential use.

Download or read book Proceedings of the Symposium on Sandalwood in the Pacific written by and published by . This book was released on 1990 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandalwood (Santalum spp.) trees grow in a variety of climates around the world and are culturally and economically important to about 15 countries. Exploitation of the fragrant heartwood for carvings, oil, and incense in the past has led to the need to conserve and manage the genus. The first substantial logging of sandalwood in Hawaii in 150 years generated local controversy in 1988, uncovered misinformation and speculation about the genus, and eventually led to the symposium in 1990. Papers in this proceedings cover history, distribution, status, ecology, management, propagation, and use of sandalwood. A synthesis paper summarizes the state-of-knowledge of the symposium participants. Research is needed to fill gaps in information on various aspects of sandalwood in many of the countries where it grows.

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." --

Available in PDF, EPUB and Kindle. Book excerpt: This publication reviews the results of research on the western pine beetle up to July 1, 1952. It shows the progress that has been made in over a half-century of study of this one bark beetle. It also records the trials and errors--the research that ran into blind alleys. The record of this pioneer effort in the field of forest entomology in the United States should be of great help to research workers who are faced with similar problems.
