Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Empire of the Beetle written by Andrew Nikiforuk and published by Greystone Books Ltd. This book was released on 2011 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning in the late 1980s, a series of improbable bark beetle outbreaks unsettled iconic forests and communities across western North America. An insect the size of a rice kernel eventually killed more than 30 billion pine and spruce trees from Alaska to New Mexico. Often appearing in masses larger than schools of killer whales, the beetles engineered one of the world's greatest forest die-offs since the deforestation of Europe by peasants between the eleventh and thirteenth centuries. The beetle didn't act alone. Misguided science, out-of-control logging, bad public policy, and a hundred years of fire suppression created a volatile geography that released the world's oldest forest manager from all natural constraints. Like most human empires, the beetles exploded wildly and then crashed, leaving in their wake grieving landowners, humbled scientists, hungry animals, and altered watersheds. Although climate change triggered this complex event, human arrogance assuredly set the table. With little warning, an ancient insect pointedly exposed the frailty of seemingly stable manmade landscapes. And despite the billions of public dollars spent on control efforts, the beetles burn away like a fire that can't be put out. Drawing on first-hand accounts from entomologists, botanists, foresters, and rural residents, award-winning journalist Andrew Nikiforuk investigates this unprecedented beetle plague, its startling implications, and the lessons it holds.

Download or read book George Meléndez Wright written by Jerry Emory and published by University of Chicago Press. This book was released on 2023-04-26 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first biography of a visionary biologist whose groundbreaking ideas regarding wildlife and science revolutionized national parks. When twenty-three-year-old George Meléndez Wright arrived in Yosemite National Park in 1927 to work as a ranger naturalist—the first Hispanic person to occupy any professional position in the National Park Service (NPS)—he had already visited every national park in the western United States, including McKinley (now Denali) in Alaska. Two years later, he would organize the first science-based wildlife survey of the western parks, forever changing how the NPS would manage wildlife and natural resources. At a time when national parks routinely fed bears garbage as part of “shows” and killed “bad” predators like wolves, mountain lions, and coyotes, Wright’s new ideas for conservation set the stage for the modern scientific management of parks and other public lands. Tragically, Wright died in a 1936 car accident while working to establish parks and wildlife refuges on the US-Mexico border. To this day, he remains a celebrated figure among conservationists, wildlife experts, and park managers. In this book, Jerry Emory, a conservationist and writer connected to Wright’s family, draws on hundreds of letters, field notes, archival research, interviews, and more to offer both a biography of Wright and a historical account of a crucial period in the evolution of US parks and the wilderness movement. With a foreword by former NPS director Jonathan B. Jarvis, George Meléndez Wright is a celebration of Wright’s unique upbringing, dynamism, and enduring vision that places him at last in the pantheon of the great American conservationists.
