Bird Habitat Relationships Along a Great Basin Elevational Gradient by Dean E. Medin Pdf
Bird censuses were taken on 11 study plots along an elevational gradient ranging from 5,250 to 11,400 feet. Each plot represented a different vegetative type or zone: shadscale, shadscale-Wyoming big sagebrush, Wyoming big sagebrush, Wyoming big sagebrush-pinyon/juniper, pinyon/juniper, pinyon/juniper-mountain big sagebrush, mountain big sagebrush, mountain big sagebrush-mixed conifer, mixed conifer, mixed conifer-alpine, and alpine. Eighty-nine bird species were observed. The total number of birds and bird species followed a skewed bell-shaped distribution. Some birds were quite narrow in their choice of vegetative zones while others showed very little selectivity. Both total number of individual birds and bird species appeared to reach highest values in study plots with a substantial component of mountain big sagebrush.
Watchable Birds of the Great Basin by David Lukas Pdf
Watchable Birds of the Great Basin offers wildlife enthusiasts, families, and birders fascinating facts about nesting behavior, birdsongs, foods, and flight characteristics of 80 of the most fun-to-watch species in Nevada and parts of Utah, Oregon, Idaho, and California.
Covering a large swath of the American West, the Great Basin, centered in Nevada and including parts of California, Utah, and Oregon, is named for the unusual fact that none of its rivers or streams flow into the sea. This fascinating illustrated journey through deep time is the definitive environmental and human history of this beautiful and little traveled region, home to Death Valley, the Great Salt Lake, Lake Tahoe, and the Bonneville Salt Flats. Donald K. Grayson synthesizes what we now know about the past 25,000 years in the Great Basin—its climate, lakes, glaciers, plants, animals, and peoples—based on information gleaned from the region’s exquisite natural archives in such repositories as lake cores, packrat middens, tree rings, and archaeological sites. A perfect guide for students, scholars, travelers, and general readers alike, the book weaves together history, archaeology, botany, geology, biogeography, and other disciplines into one compelling panorama across a truly unique American landscape.
A Natural History of Oregon's Lake Abert in the Northwest Great Basin Landscape by Ronald James Larson Pdf
A beautifully detailed exploration of flora and fauna. Author Ron Larson offers a natural history of a Great Basin landscape that focuses on the northern region including Lake Abert and Abert Rim, and the adjacent area in southcentral Oregon. Although the jewel of this landscape is a lake, the real story is the many plants and animals—from the very primitive, reddish, bacteria-like archaea that thrive only in its high-salinity waters to the Golden Eagles and ravens that soar above the desert. The untold species in and around the lake are part of an ecosystem shaped by ageless processes from massive lava flows, repeated drought, and blinding snowstorms. It is an environment rich with biotic and physical interconnections going back millions of years. The Great Basin, and in particular the Lake Abert region, is special and needs our attention to ensure it remains that way. We must recognize the importance of water for Great Basin ecosystems and the need to manage it better, and we must acknowledge how rich the Great Basin is in natural history. Salt lakes, wherever they occur, are valuable and provide critically important habitat for migratory water birds, which are unfortunately under threat from upstream water diversions and climate change. Larson’s book will help people understand that the Great Basin is unique and that wise stewardship is necessary to keep it unspoiled. The book is an essential reference source, drawing together a wide range of materials that will appeal to general readers and researchers alike.
Great Basin National Park by Gretchen M. Baker Pdf
A guide to the attractions, natural history, and cultural history of the Great Basin—perfect for tourists, naturalists, and historians. Great Basin National Park, Snake Valley, and Spring Valley cover more than 3,000 square miles across portions of Nevada and Utah, but few people know much about this diverse area. In her guidebook to Great Basin National Park, Gretchen Baker covers everything a potential visitor needs to know about one of the country’s best-kept secrets. The park sits in one of America’s driest, least populated, and most isolated deserts. It is a place of significant geological and scenic value, offering unspoiled vistas, abundant wildlife, clean air, and natural attractions. That contrast is one facet of the diversity that characterizes this region. Within and outside the park are phenomenal landscape features, biotic wonders, unique environments, varied historic sites, and the local colors of isolated towns and ranches. Vast Snake and Spring Valleys, bracketing the national park, are also subjects of one of the West’s most divisive environmental contests. At stake is what on the surface seems almost absent but underground is abundant enough for sprawling Las Vegas to covet—water. This guidebook not only describes the peaks, glaciers, subalpine lakes, caves, hiking trails, campgrounds, and historical sites, but also explores the cultural history of the park and surrounding area. Each chapter addresses the physical attributes and navigational issues of a specific area and includes an in-depth historical overview. The text is complemented by useful maps and historical photographs and makes Great Basin National Park: A Guidebook to the Park and Surrounding Area the most comprehensive book on the region available.
