Book excerpt: National parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

Download or read book Cactus Opuntia Spp as Forage written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2001 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opuntias are multipurpose plants that are increasingly being used in agricultural systems in arid and semi-arid areas. Due to its high water-use efficiency, it is particularly useful as forage in times of drought and in areas where few other crops can grow, and it is now considered a key component for the productivity and sustainability of these regions. This publication presents current scientific and practical information on the use of the cactus Opuntia as forage for livestock.

This book was released on 2018-06-05 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cactus plants are precious natural resources that provide nutritious food for people and livestock, especially in dryland areas. Originally published in 1995, this extensively revised edition provides fresh insights into the cactus plant’s genetic resources, physiological traits, soil preferences and vulnerability to pests. It provides invaluable guidance on managing the resource to support food security and offers tips on how to exploit the plant’s culinary qualities.
Download or read book Distribution Ecology written by Marcelo Hernán Cassini and published by Springer Science & Business Media. This book was released on 2013-03-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.
Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
