Download or read book Birder Interrupted written by M. Ralph Browning and published by Wipf and Stock Publishers. This book was released on 2024-02-15 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inspired by Roger Tory Peterson and James Fisher’s book Wild America, recent high school graduate M. Ralph Browning embarked on a tightly budgeted, year-long trip in the US looking for birds. The year was 1962. His 1955 VW Beetle broke after nine months, which forced a premature end to the journey. In 2005, after matters of military duty, college, a family, and a career in birds at Smithsonian’s National Museum of Natural History, the author resumed the interrupted trip. This time, he was with the girl he’d left behind in 1962, and they birded Texas, the Southwest, and California. The author chronicles the trip with observations on birds while touching on history, geology, and conservation. The cost of keeping alive includes periodic notes on the price of gasoline (about $0.33/gallon in 1962) and food. The author had earlier written to numerous birders for information about birding particular locations, and many of those individuals across the country showed him birds and invited him into their homes for a gratefully appreciated warm bed and home cooking. The 2005 leg of the journey was assisted by bird finding guides and the help of the legendary Jon Dunn and numerous motels.
Download or read book Whitebark Pine Communities written by Diana F. Tomback and published by Island Press. This book was released on 2001 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.

Download or read book This Land written by Robert H. Mohlenbrock and published by Univ of California Press. This book was released on 2006-03-09 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part armchair travelogue, part guide book, this projected three-volume series—divided into the western, central, and eastern United States—will introduce readers to all 155 national forests across the country. This Land is the only comprehensive field guide that describes the natural features, wildernesses, scenic drives, campgrounds, and hiking trails of our national forests, many of which—while little known and sparsely visited—boast features as spectacular as those found in our national parks and monuments. Each entry includes logistical information about size and location, facilities, attractions, and associated wilderness areas. For about half of the forests, Robert H. Mohlenbrock has provided sidebars on the biological or geological highlights, drawn from the "This Land" column that he has written for Natural History magazine since 1984. Superbly illustrated with color photographs, botanical drawings, and maps, this book is loaded with information, clearly written, and easy to use. This volume covers national forests in: Alaska, Nevada, Arizona, Oregon, California, Utah, Idaho, Washington
Download or read book Encyclopedia of Invasive Species 2 volumes written by Susan L. Woodward and published by Bloomsbury Publishing USA. This book was released on 2011-09-22 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume set provides a one-stop resource on invasive plants, animals, fungi, and microorganisms that are threatening native ecosystems, agriculture, economies, and human health in the United States. Kudzu vine and field bindweed. Eurasian collared-doves, Burmese pythons, and black rats. The northern snakehead and the gypsy moth. All of these are examples of invasive species that have taken over or are threatening certain ecosystems—places where these organisms never naturally occurred. This two-volume work contains 168 entries on plants, animals, fungi, and microorganisms that are invasive in the United States, providing a complete examination of the variety of organisms, pathways, distribution patterns, and impacts of non-native species introduced to this country. Encyclopedia of Invasive Species: From Africanized Honey Bees to Zebra Mussels begins with a background essay that illuminates the complexities of dealing with invasive animals and plants. Each entry provides information on the origins and invasion history of the species in question as well as a general description of the biology and ecology of each organism. Impacts—actual and potential, as well as management strategies—are addressed. Every species is depicted via photographs as well as maps that show its place of origin and invaded regions in the United States. This unique work presents fascinating scientific information as well as valuable insights about how seemingly minor events can drastically alter our environment.
Download or read book Research Natural Area Needs in the Pacific Northwest written by C. T. Dyrness and published by . This book was released on 1975 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Natural Areas are examples of typical and distinctive natural ecosystems and habitats reserved for scientific and educational use. This outline of the minimal Research Natural Area system needed to provide adequate field laboratories for ecological, environmental, and land management research was developed by an interinstitutional, interdisciplinary working group. Natural area needs were first described on the basis of individual organisms, habitats, or ecosystems which should be represented. These "cells," the basic building blocks in defining the total scope of the system, considered terrestrial and aquatic environments as well as rare and endangered species. Identified cells were matched against existing Research Natural Areas to determine which were already filled. The remaining, unfilled cells were then tentatively grouped as units which were listed as Research Natural Area needs. A minimal Research Natural Area system for Oregon and Washington requires approximately 360 tracts which, in turn, incorporate over 770 individual cells (ecosystems, habitats, or organisms). Since 60 Research Natural Areas are already established, about 300 additional areas are needed. These remaining needs were assigned a priority (low, medium, or high) based on importance and degree to which they are endangered, as well as identified as to the Federal, State, or private agency or institution most likely to be able to provide a tract of that type. The purpose of Research Natural Areas, their place in land planning, history of Research Natural Area activities in the Pacific Northwest, and general observations and recommendations on unresolved problems are also outlined.
