Hydrologic Processes in the Pinyon-juniper Woodlands


Book Description

Hydrologic processes in the pinyon-juniper woodlands of the western region of the United States are variable because of the inherent interactions among the occurring precipitation regimes, geomorphological settings, and edaphic conditions that characterize the ecosystem. A wide range of past and present land-use practices further complicates comprehensive evaluations of these hydrologic processes. Heterogeneous vegetative covers make it even more difficult to generalize hydrologic processes and the effects of land management practices on the water balance. Nevertheless, estimates of interception, infiltration, evapotranspiration, soil moisture storage, and hillslope soil erosion of these on-site hydrologic processes have been obtained in plot studies. Estimates of off-site streamflow volumes, sediment yields and transport, and quality of streamflow water are available from the results of watershed-level investigations. Estimates of these respective hydrologic processes are presented in this general technical report.

Hydrology and the Management of Watersheds


Book Description

This new edition is a major revision of the popular introductory reference on hydrology and watershed management principles, methods, and applications. The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use watersheds. Case studies and examples throughout the book show practical ways to use web sites and the Internet to acquire data, update methods and models, and apply the latest technologies to issues of land and water use and climate variability and change.




Ecology, Diversity, and Sustainability of the Middle Rio Grande Basin


Book Description

Synthesizes existing information on the ecology, diversity, human uses & research needs of the Middle Rio Grande Basin of New Mexico. Begins with a review of the environmental history & human cultures of the basin, followed by an analysis of the influences & problems of climate & water. Also focuses on ecological processes, environmental changes & management problems. Each chapter identifies studies that can supply information to mitigate environmental problems, rehabilitate ecosystems, & sustain them in light of human values & needs.

Ecology, Management, and Restoration of Piñon-juniper and Ponderosa Pine Ecosystems


Book Description

Southwestern piñon-juniper and juniper woodlands cover large areas of Arizona, New Mexico, Utah, and adjacent Colorado. Ponderosa pine forests are the most common timberland in the Southwest. All three ecosystems provide a variety of natural resources and economic benefits to the region. There are different perceptions of desired conditions. Public and private land managers have adapted research results and their observations and experiences to manage these ecosystems for multiresource benefits. Ways to mitigate the threat of wildfires is a major management issue for these ecosystems, and the wide-spread piñon mortality related to drought and the bark beetle infestation has heightened concerns among managers and the general public. In addition, the impacts of climate change on these ecosystems are a growing concern. As a step in bringing research and management together to answer some of these questions, workshops concerned with the ecology, management, and restoration of piñon-juniper and ponderosa pine ecosystems were held in St. George, Utah in 2005 and in Albuquerque, New Mexico in 2006. The combined proceedings from these two workshops contain papers, extended abstracts, and abstracts based on oral and poster presentations. Some topics included forest and woodland restoration treatments and their impacts on fuels, wildlife, and other ecosystem components, watershed management, insect infestations and drought, wood utilization, landscape changes, basic ecology, and more.
