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.

This book synthesizes existing information on the ecology, diversity, human uses, and research needs of the Middle Rio Grande Basin of New Mexico. Divided into nine chapters, the volume begins with reviews of the environmental history and human cultures in the Basin, followed by an analysis of the influences and problems of climate and water. Later chapters focus on ecological processes, environmental changes, management problems, and current conditions in Basin ecosystems identified as being especially susceptible to damage: pinyon-juniper woodlands, grasslands and shrublands, and the riparian bosque of the Rio Grande. Research needs associated with land management problems are identified for each of these ecosystem types. Many interrelated factors, identified here, have contributed to deteriorating environmental conditions in the Basin. Concluding chapters on the belowground ecology of specific Basin ecosystems and on declining populations of native fish species highlight topics in need of further attention. Each chapter seeks to identify studies that can supply information to mitigate environmental problems, rehabilitate ecosystems, and sustain them in light of human values and needs.

This document provides managers with a literature synthesis of the historical conditions, current conditions, fire regime condition classes (FRCC), and recommended treatments for the major ecosystems in southern Utah. Sections are by ecosystems and include: 1) coniferous forests (ponderosa pine, mixed conifer, and Engelmann spruce-subalpine fir), 2) aspen, 3) pinyon-juniper, 4) big and black sagebrush, and 5) desert shrubs (creosotebush, blackbrush, and interior chaparral). Southern Utah is at the ecological crossroads for much of the western United States. It contains steep environmental gradients and a broad range of fuels and fire regimes associated with vegetation types representative of the Rocky Mountains, the Great Basin, Northern Arizona and New Mexico, and the Mohave Desert. The Southern Utah Demonstration Area consists of contiguous state and federal lands within the administrative boundaries of the Bureau of Land Management (BLM), Fishlake and Dixie National Forests, National Park Sevice, and State of Utah, roughly encompassing the southern 15 percent of Utah (3.24 million ha). The vegetation types described are similar in species composition, stand structure, and ecologic function, including fire regime to vegetation types found on hundreds of millions of hectares in the 11 western states.

These proceedings are an outcome of a symposium and workshop held June 2-5, 1998 in Albuquerque, NM. Hosted by the USDA Forest Service, Rocky Mountain Research Station and the U.S. Fish and Wildlife Service's Bosque Improvement Group, in collaboration with numerous partners from a variety of sectors, the symposium was designed to report on current research and development activities in the Middle Rio Grande Basin. The purpose of the meeting was to share information and develop ideas for sustaining and conserving Middle Rio Grande Basin ecosystems, especially those from Cochiti Dam to Elephant Butte Reservoir. Experts were invited to contribute oral presentations, posters, and papers that addressed five Basin themes. Theme one's session was designed to identify methods and opportunities to enhance communication and collaboration among researchers, managers, and communities. A second theme explored ideas and approaches for conserving water and riparian resources in relation to human needs and population growth. Theme three discussed how watershed processes form linkages and influence management of upland and river resources. A fourth session identified methods and strategies for restoring and monitoring basin ecosystems and discussed project successes and failures. Theme five reported on status of endangered and sensitive species, biological diversity, and opportunities for restoring and managing habitats to recover species. Management and understanding of the Middle Rio Grande Basin's natural resources and ecosystems require communication and cooperation of partners across cultural, landowner, and organizational boundaries. To produce a shared understanding of the current state and desired future state of the Middle Rio Grande Basin and to outline the steps needed to move toward the desired future, a facilitated workshop was held the last day of the conference. The results of this workshop are reported in the concluding section of this proceedings. The technical coordinators of the symposium and proceedings wish to acknowledge all the partners who have contributed to the research, restoration, technology development, educational outreach, and special events and activities designed to improve human and ecosystem conditions in the Basin. We hope this volume captures at least some of the excitement, ideas, and productivity generated by Basin projects over the past several years.

This report documents an ecological assessment of forest ecosystem health in the Southwest. The assessment focuses at the regional level and mostly pertains to lands administered by the National Forest System. Information is presented for use by forest and district resource managers as well as collaborative partners in the stewardship of Southwestern forests. The report establishes a scientific basis for conducting forest health projects, provides a context for planning ecosystem restoration, and contributes to the understanding of the physical, biological, and human dimensions of these ecosystems. Chapters describe Southwestern forest ecosystems of the past, changes since the Colonial Period, and the implications of those changes for the health of current and future forests. Opportunities, tools, and research needs for improving ecosystem sustainability are also identified.

Nontimber forest products (NTFPs) are fundamental to the functioning of healthy forests and play vital roles in the cultures and economies of the people of the United States. However, these plants and fungi used for food, medicine, and other purposes have not been fully incorporated into management, policy, and resource valuation. This report is a forest-sectorwide assessment of the state of the knowledge regarding NTFPs science and management information for U.S. forests and rangelands (and hereafter referred to as the NTFP assessment). The NTFP assessment serves as a baseline science synthesis and provides information for managing nontimber forest resources in the United States. In addition, this NTFP assessment provides information for national-level reporting on natural capital and the ecosystem services NTFPs provide. The report also provides technical input to the 2017 National Climate Assessment (NCA) under development by the U.S. Global Change Research Program (USGCRP).
