Book excerpt: 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.

This book was released on 2007-07-17 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This completely new edition of Terrestrial Vegetation of California clearly documents the extraordinary complexity and richness of the plant communities and of the state and the forces that shape them. This volume is a storehouse of information of value to anyone concerned with meeting the challenge of understanding, managing or conserving these unique plant communities under the growing threats of climate change, biological invasions and development."—Harold Mooney, Professor of Environmental Biology, Stanford University "The plants of California are under threat like never before. Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley
Download or read book Patterns of Big Sagebrush Plant Community Composition and Stand Structure in the Western United States cVictoria E Pennington John B Bradford Kyle A Palmquist Rachel R Renne and William K Lauenroth written by Victoria E. Pennington and published by . This book was released on 2019 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big sagebrush (Artemisia tridentata Nutt.) plant communities are found in western North America and comprise a mix of shrubs, forbs, and grasses. Climate, topography, and soil water availability are important factors that shape big sagebrush stand structure and plant community composition; however, most studies have focused on understanding these relationships at sites in a small portion of the big sagebrush region. Our goal was to characterize detailed stand structure and plant composition patterns and identify environmental variables related to those patterns by sampling 15 sites distributed across the western United States. In each site, we characterized stand structure at the individual shrub level and at the site level. We quantified size distributions and assessed relationships among canopy volume, age, and height. We also characterized functional type cover and species composition and related those to climatic, topographic, and edaphic variables. Mean big sagebrush age ranged from 21 (±8) to 57 (±22) yr at individual sites, mean height ranged from 0.23 (±0.12) to 0.67 (±0.23) m, and mean canopy volume ranged from 0.03 (±0.04) to 0.62 (±0.51) m3. Bare ground and litter contributed the most cover (mean = 64%), followed by big sagebrush (mean = 39% of vascular plant cover). There was a negative relationship between big sagebrush cover and grass and forb cover. Species composition was related to both climate and elevation, likely because these variables influence water availability. Although our study was limited to 15 field sites, our detailed descriptions of widely distributed sites provide insight into the magnitude of variability in big sagebrush plant community structure.

Book excerpt: Biotic Communities catalogs and defines by biome, or biotic community, the region centered on Arizona, New Mexico, Sonora, Chihuahua, and Baja California Norte, plus portions of California, Nevada, Utah, Colorado, Texas, Coahuila, Sinaloa, and Baja California Sur. This ambitious guide is an essential companion for anyone working in natural resources management and ecological research, as well as nonspecialists looking for solid information about a particular southwestern locale. Biotic Communities is arranged by climatic formation with a short chapter for each biome describing climate, physiognomy, distribution, dominant and common plant species, and characteristic vertebrates. Subsequent chapters contain careful descriptions of zonal subdivisions.
Download or read book Natural History of the White Inyo Range Eastern California written by Clarence A. Hall and published by Univ of California Press. This book was released on 1991-01-01 with total page 660 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The mixed grass and shrub vegetation known to scientists as desert grassland is common to the basins and valleys that skirt the mountain ranges throughout southwestern North America, extending from Arizona, New Mexico and Texas down through thirteen Mexican states. This variegated ground cover is crucial to life in an arid environment. The Desert Grassland offers the most comprehensive study to date of these flora and the rich biotic communities they support. Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice-age forests that existed in these areas before the climate dried and the trees vanished and how the intensity and frequency of fire can influence the plant and animal species of the grassland. They also document how the influence of humans—from Amerindians to contemporary ranchers, public land managers, and real estate developers—has changed the relative abundance of woody and herbaceous species and how the introduction of new plants and domesticated animals to the area has also affected biodiversity. The book concludes with a review of the attempts, both failed and successful, to reestablish plants in desert grasslands affected by overgrazing, drought, and farm abandonment. Meticulously researched and copiously illustrated, The Desert Grassland is a major contribution to ecological literature. For advanced lay readers as well as students and scholars of history, geography, and ecology, it will be a standard reference work for years to come.
