Download or read book Woody Plants of Utah written by Renee Van Buren and published by University Press of Colorado. This book was released on 2012-01-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive guide that includes a vast range of species and plant communities and employs thorough, original keys. Based primarily on vegetative characteristics, the keys don't require that flowers or other reproductive features be present, like many plant guides. And this guide's attention to woody plants as a whole allows one to identify a much greater variety of plants. That especially suits an arid region such as Utah with less diverse native trees. Woody plants are those that have stems that persist above ground even through seasons that don't favor growth, due to low precipitation or temperatures. Woody Plants of Utah employs dichotomous identification keys that are comparable to a game of twenty questions. They work through a process of elimination by choosing sequential alternatives. Detailed, illustrated plant descriptions complement the keys and provide additional botanical and environmental information in relation to a useful introductory categorization of Utah plant communities. Supplementary tools include photos, distribution maps, and an illustrated glossary.

Download or read book Baboquivari Mountain Plants written by Daniel F. Austin and published by University of Arizona Press. This book was released on 2022-05-03 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Baboquivari Mountains, long considered to be a sacred space by the Tohono O’odham people who are native to the area, are the westernmost of the so-called Sky Islands. The mountains form the border between the floristic regions of Chihuahua and Sonora. This encyclopedic work describes the flora of this unique area in detail. It includes descriptions, identifications, ecology, and extensive etymologies of plant names in European and indigenous languages. Daniel Austin also describes pollination biology and seed dispersal and explains how plants in the area have been used by humans, beginning with Native Americans. The term “sky island” was first used by Weldon Heald in 1967 to describe mountain ranges that are separated from each other by valleys of grassland or desert. The valleys create barriers to the spread of plant species in a way that is similar to the separation of islands in an ocean. The 70,000-square-mile Sky Islands region of southeastern Arizona, southwestern New Mexico, and northwestern Mexico is of particular interest to botanists because of its striking diversity of plant species and habitats. With more than 3,000 species of plants, the region offers a surprising range of tropical and temperate zones. Although others have written about the region, this is the first book to focus exclusively on the plant life of the Baboquivari Mountains. The book offers an introduction to the history of the region, along with a discussion of human influences, and includes a useful appendix that lists all of the plants known to be growing in the Baboquivari Mountain chain.
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.

Available in PDF, EPUB and Kindle. Book excerpt: IUCN's Protected Areas Management Categories, which classify protected areas according to their management objectives, are today accepted as the benchmark for defining, recording, and classifying protected areas. They are recognized by international bodies such as the United Nations as well as many national governments. As a result, they are increasingly being incorporated into government legislation. These guidelines provide as much clarity as possible regarding the meaning and application of the Categories. They describe the definition of the Categories and discuss application in particular biomes and management approaches.

Download or read book Non Native Plants of Organ Pipe Cactus National Monument Arizona Classic Reprint written by Richard S. Felger and published by Forgotten Books. This book was released on 2017-12-11 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Non-Native Plants of Organ Pipe Cactus National Monument, Arizona The vascular (or seed) plant flora of Organ Pipe Cactus National Monument (orpi) contains remarkably few species of non-native plants. A low percentage of non-native, introduced, or exotic plants indicates the habitat is relatively natural, and as such can be used as an index of the condition of the vegetation. The present report includes 64 species possibly non-native to orpi which have been documented from the monument or adjacent regions and potentially present or invasive into the monument. In addition, a few species previously thought to be present and non-native to orpi were found to be either native or possibly native or not present.

Download or read book Plant Life of a Desert Archipelago written by Richard Stephen Felger and published by University of Arizona Press. This book was released on 2013-01-31 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desert islands of the Gulf of California are among the world's best-preserved archipelagos. The diverse and unique flora, from the cardón forests of Cholludo to the agave-dominated slopes of San Esteban remain much as they were centuries ago, when the Comcaac (Seri people) were the only human presence in the region. Almost 400 plant species exist here, with each island manifesting a unique composition of vegetation and flora. For thousands of years, climatic and biological forces have sculpted a set of unparalleled desert worlds. Plant Life of a Desert Archipelago is the first in-depth coverage of the plants on islands in the Gulf of California found in between the coasts of Baja California and Sonora. The work is the culmination of decades of study by botanist Richard Felger and recent investigations by Benjamin Wilder, in collaboration with Sr. Humberto Romero-Morales, one of the most knowledgeable Seris concerning the region's flora. Their collective effort weaves together careful and accurate botanical science with the rich cultural and stunning physical setting of this island realm. The researchers surveyed, collected, and studied thousands of plants—seen here in meticulous illustrations and stunning color photographs—providing the most precise species accounts of the islands ever made. To access remote parts of the islands the authors worked directly with the Comcaac, an indigenous community who have lived off marine and terrestrial life in this coastal desert region for centuries. Invaluable information regarding indigenous names and distributions are an intrinsic part of this work. The flora descriptions are extraordinarily detailed and painstakingly crafted for field biologists. Conservationists, students, and others who are interested in learning about the natural wealth of the Gulf of California, desert regions, or islands in general are sure to be captivated by this rich and fascinating volume.
