Book excerpt: Excerpt from Entomological Phases of the 1961 Lodgepole Needle Miner Control Project in Yosemite National Park The principal entomological jobs were (1) to determine when the popu lation reached the proper stage of development for Spraying, and (2) to measure the degree of control attained. This work was done by the Experiment Station, which assisted the Park on the technical phases of the project. Needle miner development during the late larval, pupal, and early adult stages was determined by daily sampling throughout the control area, from.june 6 to August A. Spraying began as planned when about one-quarter of the needle miners reached the adult stage, and When it ended three-quarters of them were in this stage. The target date for starting Spraying was accurately predicted from the sampling data 1 month in advance.

Download or read book Creating the National Park Service written by Horace M. Albright and published by University of Oklahoma Press. This book was released on 1999 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two men played a crucial role in the creation and early history of the National Park Service: Stephen T. Mather, a public relations genius of sweeping vision, and Horace M. Albright, an able lawyer and administrator who helped transform that vision into reality. In Creating the National Park Service, Albright and his daughter, Marian Albright Schenck, reveal the previously untold story of the critical "missing years" in the history of the service. During this period, 1917 and 1918, Mather's problems with manic depression were kept hidden from public view, and Albright, his able and devoted assistant, served as acting director and assumed Mather's responsibilities. Albright played a decisive part in the passage of the National Park Service Organic Act of 1916; the formulation of principles and policies for management of the parks; the defense of the parks against exploitation by ranchers, lumber companies, and mining interests during World War I; and other issues crucial to the future of the fledgling park system. This authoritative behind-the-scenes history sheds light on the early days of the most popular of all federal agencies while painting a vivid picture of American life in the early twentieth century.

Download or read book Ecology written by Charles J. Krebs and published by Benjamin-Cummings Publishing Company. This book was released on 2001 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Book excerpt: The White-Inyo Range--rising sharply from the eastern edge of Owens Valley--is one of the most extraordinary landscapes in the world. High, dry, and amazingly diverse, it boasts an expansive alpine tundra and features the oldest living species on earth--the 4,000-year-old Bristlecone Pines. This colorful and authoritative volume assembles a wealth of information of deep interest to the hikers and scientists attracted to White-Inyo's altitude and isolation. The nearly two dozen contributors to the volume are leading experts on the flora and fauna, the geology, geomorphology, meteorology, anthropology, and archaeology of the area. The book offers descriptions of more than 650 kinds of living organisms, from the handful of fish to the abundance of reptile, amphibian, bird and plant species. (It provides descriptions of hundreds of flowering plants.) It contains an 8-color geologic map and a roadside guide that enables the visitor to make sense of the area's complex geological history. Readers will also learn about air currents that make the range a delight for sailplane pilots and create strange cloud formations. And a special chapter tells what is known of the Native Americans who moved up and down the mountain slopes in response to seasonal changes. For anyone who wishes to visit this astonishing area or to do research there, this volume will be a unique, comprehensive resource.

Download or read book Forty Years a Forester written by Elers Koch and published by U of Nebraska Press. This book was released on 2019-10 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elers Koch, a key figure in the early days of the U.S. Forest Service, was among the first American-trained silviculturists, a pioneering forest manager, and a master firefighter. By horse and on foot, he helped establish the boundaries of most of our national forests in the West, designed new fire-control strategies and equipment, and served during the formative years of the agency. Forty Years a Forester, Koch’s entertaining and illuminating memoir, reveals one remarkable man’s contributions to the incipient science of forest management and his role in building the human relationships and policies that helped make the U.S. Forest Service, prior to World War II, the most respected bureau in the federal government. This new, fully annotated edition of Koch’s memoir offers an unparalleled look at the Forest Service’s formative ambitions to regulate the national forests and grasslands and reminds us of the principled commitment that Koch and his peers exemplified as they built the national forest system and nurtured the essential conservation ethic that continues to guide our use of the public lands.
