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.

A hybrid approach for predictive soil property mapping using conventional soil survey data A hybrid approach for predictive soil property mapping using conventional soil survey data
Soil property maps are important for land management and earth systems modeling. A new hybrid point-disaggregation predictive soil property mapping strategy improved mapping in the Colorado River Basin, and can be applied to other areas with similar data (e.g. conterminous United States). This new approach increased sample size ~6-fold over past efforts. Random forests related...

Seasonal and individual event-responsiveness are key determinants of carbon exchange across plant functional types Seasonal and individual event-responsiveness are key determinants of carbon exchange across plant functional types
Differentiation in physiological activity is a critical component of resource partitioning in resource-limited environments. For example, it is crucial to understand how plant physiological performance varies through time for different functional groups to forecast how terrestrial ecosystems will respond to change. Here, we tracked the seasonal progress of 13 plant species representing...

Natural and anthropogenic processes affecting radon releases during mining and early stage reclamation activities, Pinenut uranium mine, Arizona, USA Natural and anthropogenic processes affecting radon releases during mining and early stage reclamation activities, Pinenut uranium mine, Arizona, USA
Radon (Rnair) was monitored in open air in publicly accessible areas surrounding the Pinenut uranium (U) mine during mining and reclamation activities in 2015–16 to address concerns about mining related effects to areas surrounding Grand Canyon National Park (GCNP) in Arizona, USA. During July 2015, Rnair concentrations associated with the ore storage pile monitoring site were larger...

Assessment of rangeland ecosystem conditions in Grand Canyon-Parashant National Monument, Arizona Assessment of rangeland ecosystem conditions in Grand Canyon-Parashant National Monument, Arizona
Sustainability of dryland ecosystems depends on the functionality of soil-vegetation feedbacks that affect ecosystem processes, such as nutrient cycling, water capture and retention, soil erosion and deposition, and plant establishment and reproduction. Useful, common indicators can provide information on soil and site stability, hydrologic function, and biotic integrity. Evaluation of...

Bridging the research-management gap: Landscape ecology in practice on public lands in the western United States Bridging the research-management gap: Landscape ecology in practice on public lands in the western United States
The field of landscape ecology has grown and matured in recent decades, but incorporating landscape science into land management decisions remains challenging. Many lands in the western United States are federally owned and managed for multiple uses, including recreation, conservation, and energy development. We argue for stronger integration of landscape science into the management of...

Supporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 19 Report) Supporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 19 Report)
A primary focus of the Bureau of Land Management’s (BLM’s) Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration and have identified...
