This history was compiled from the memoirs, diaries, and other personal documents of the two forest entomologists in charge of the first forest insect laboratories on the west coast. It traces the lives of the two pioneers from 1902 to 1952 as they pursued their careers in the USDA Bureau of Entomology, Division of Forest Insect Investigations. Cooperative bark beetle control projects with the USDA Forest Service, Park Service, and private timber owners guided much of their early activities. Later, when the laboratories were located on university campuses, cooperative research was undertaken with Forest Service Research Stations. The focus shifted to more basic research and, particularly, studies on the silvicultural management of bark beetle populations.

"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." --

Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.
