Digital Soil Mapping: High Resolution Maps for Modern Land Management Decisions

The field of digital soil mapping has bridged the classic theories of soil science into the modern computing age to produce high resolution maps. This body of work utilizes classic soil factorial theory (soil = f[climate, organisms, relief (topography), parent material, time] + ɛ, or ‘clorpt’). The clorpt framework has been approximated using various environmental spatial data layers to...

Wind Erosion and Dust Emissions on the Colorado Plateau

Wind erosion of soils and dust emissions are a significant resource management challenge on the Colorado Plateau. Loss of topsoil and associated aeolian sediment (wind-driven sediment) movement can lead to reduced soil fertility as well as abrasion and burial of vegetation. Dust in the atmosphere poses a threat to human health, visual resources, and regional water supplies (due to interactions...

Long-Term Vegetation Change on the Colorado Plateau

Drylands comprise ~35% of Earth’s terrestrial biomes, with over 1 billion people depending on these landscapes for their livelihoods. In the U.S., drylands comprise ~40% of the landmass and 83% of Department of Interior (DOI)-managed lands (excluding Alaska). Due to their vast extent nationally and globally, changes to these landscapes have the potential to affect global climate regulation. A...

RestoreNet: Distributed Field Trial Network for Dryland Restoration

Recovery from disturbance represents a substantial challenge to agencies that manage large tracts of land in the Southwest. Despite the demand for restoration and rehabilitation, little information is available to help managers effectively reestablish native perennial vegetation and stabilize soils, especially given changing climate and disturbance regimes.

Forestry and agriculture have...

Colorado Plateau Futures: Understanding Agents of Change on the Colorado Plateau to Facilitate Collaborative Adaptation

The objective of this interdisciplinary research effort is to 1) characterize agents of change important to land management decision makers on the Colorado Plateau; 2) identify and analyze relationships between agents of change and key landscape attributes and processes; 3) collectively assess the influence of agents of change and attributes and processes on the services provided by the...

Southwest Energy Development and Drought (SWEDD)

Deserts of the southwestern US are replete with oil and gas deposits as well as sites for solar, wind, and geothermal energy production. In the past, many of these resources have been too expensive to develop, but increased demand and new technologies have led to an increase in exploration and development. However, desert ecosystems generally have low resilience to disturbance. More frequent,...

Amazon Dams Network: Advancing Integrative Research and Adaptive Management of Social-Ecological Systems Transformed by Hydroelectric Dams

The overall goal of this project is to advance inter- and trans-disciplinary research coordination, focusing on the transformation of social-ecological systems by hydroelectric dam construction in the Amazon and the United States. The experience gained by Southwest Biological Science Center researchers working on the...

Informing Renewable Energy Development Siting Decisions with Vertebrate Biodiversity Measures

Renewable energy development is expanding in southwestern deserts, including in Arizona. Energy developers look to resource management agencies to provide siting guidance on public lands where there might be conflicts with wildlife. Often, agency guidance considers species of conservation concern and economic importance, but information on comprehensive vertebrate biodiversity has been hard to...

Biofuels in the Southwest

Concerns about energy security and rising greenhouse gas emissions have stimulated an unprecedented increase in the push for alternative energy use, including the use of plant biomass as a source of renewable energy (bioenergy). However, meeting alternative energy goals, while also meeting food demands and mitigating potential detrimental effects of industrialized agriculture, has emerged as a...

A Field Guide to Biological Soil Crusts of Western U.S. Drylands

Biological soil crusts (biocrusts) are commonly found on the soil surface in arid and semi-arid ecosystems (collectively called drylands). Biocrusts can consist of mosses, cyanobacteria, lichens, algae, and microfungi, and they strongly interact with the soil. These organisms or consortium of disparate organisms, depending on the specific biocrust, are important to the functioning of...

Restoration and Ecosystem Recovery Dynamics in Arid and Semiarid Landscapes

Dryland regions have been degraded by invasive species, wildfire, overgrazing, agricultural conversion, energy development, recreational activity, and urban growth. These disturbances and others are accelerated by one of the fastest growing human populations in the country and a pressing background of decreasing water availability due to drought and elevated temperatures that are projected to...

Economics of Outdoor Recreation

Economic research at Grand Canyon Monitoring and Research Center is used to determine economic benefits of outdoor recreation in Glen Canyon National Recreation Area below Glen Canyon Dam and in Grand Canyon National Park, as affected by operation of Glen Canyon Dam. This research identifies recreationists’ preferences for attributes associated with their trips, spending that occurs regionally...
