Mike Duniway, Ph.D.
Dr. Michael (Mike) Duniway is a soil scientist focused on soils and soil processes in dryland environments. His work provides crucial information for stakeholders, agencies and the public to assess and manage lands across the Colorado Plateau and southwest US.
In his research and outreach activities, Dr. Duniway seeks to provide information for land managers and owners to facilitate sustainable land-use activities. He works closely with federal and state agency partners and others in designing research studies, conducting technology transfer, and outreach activities. His research focuses include understanding the impacts of drought on Colorado Plateau rangelands, evaluating the recovery of oil and gas pads and seeking opportunities for improved reclamation practices, and developing new maps and tools for land management. In his work, he is interested in maintaining and balancing the important ecosystem services these landscapes provide, including clean water and air, food and fiber, tourism and cultural values, and energy.

Learning From the Past and Planning for the Future: Experience-Driven Insight Into Managing for Ecosystem Transformations Induced by Drought and Wildfire
Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades. In...
Drylands are highly vulnerable to climate and land use changes: what ecosystem changes are in store?
Improper land use during drought has been a major driver of land degradation in drylands globally, especially in the western U.S. Increasing aridity in western U.S. drylands under future climates will exacerbate risks associated with drought and land use decisions. This project provides critical observational, experimental, and modelling evidence to support our DOI partners with decision processes...
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
The Colorado Plateau, centered around the four corners area of the Southwest, and includes much of Arizona, Utah, Colorado, and New Mexico, is a large and important component of U.S. drylands. This important home to mountains, desert basins, dramatic canyons, arid woodlands, and grasslands is also one of North America’s most rapidly warming hot spots, with rates of warming of up to 2-3° C within...
Using Long-Term Remote Sensing and an Automated Reference Toolset To Estimate and Predict Post-Development Recovery Potential
USGS scientists are using a time-varying approach to monitor and predict recovery of sagebrush ecosystems following disturbance.
Smart Energy Development: Tools for Informed Development & Successful Reclamation
The USGS is developing science and decision support tools to inform policy and management decisions about various aspects of the energy development life cycle.
RestoreNet: Distributed Field Trial Network for Dryland Restoration
Starting in 2017, U.S. Geological Survey (USGS) researchers and land managers are co-producing a network of restoration field trial sites on Department of Interior (DOI) and surrounding lands in the southwestern U.S. The network systematically tests restoration treatments across a broad range of environmental gradients. Each site in the network is used to test suitable seed mixes and treatments...
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 ecosystem...
Colorado Plateau Native Plant Program Field Trial Study
In the southwest US, monsoon precipitation increases sharply along a northwest to southeast gradient. Pleuraphis jamesii or galleta grass, is an important C4 grass species that spans across this large range in precipitation pattern. In this study we are assessing the ability of galleta grass to adapt to changes in the seasonality of rainfall (termed “plasticity”). In the fall of 2014, we...
New Approaches for Restoring Colorado Plateau Grasslands
Historic over-grazing of arid grasslands in the Intermountain West has led to widespread soil erosion, loss of plant diversity, and invasion by exotic species. Degraded grassland conditions can be very persistent, even after livestock use has ceased. For example, in national parks on the Colorado Plateau, livestock have been excluded for decades, but soil and native plants have not recovered on...
Climate change and ecohydrology in temperate dryland ecosystems: a global assessment
Water cycling and availability exert dominant control over ecological processes and the sustainability of ecosystem services in water - limited ecosystems. Consequently, dryland ecosystems have the potential to be dramatically impacted by hydrologic alterations emerging from global change, notably increasing temperature and altered precipitation patterns. In addition, the possibility of...
