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.

Functional group, biomass, and climate change effects on ecological drought in semiarid grasslands Functional group, biomass, and climate change effects on ecological drought in semiarid grasslands
Water relations in plant communities are influenced both by contrasting functional groups (grasses, shrubs) and by climate change via complex effects on interception, uptake and transpiration. We modelled the effects of functional group replacement and biomass increase, both of which can be outcomes of invasion and vegetation management, and climate change on ecological drought (soil...

Future soil moisture and temperature extremes imply expanding suitability for rainfed agriculture in temperate drylands Future soil moisture and temperature extremes imply expanding suitability for rainfed agriculture in temperate drylands
The distribution of rainfed agriculture is expected to respond to climate change and human population growth. However, conditions that support rainfed agriculture are driven by interactions among climate, including climate extremes, and soil moisture availability that have not been well defined. In the temperate regions that support much of the world’s agriculture, these interactions are

Fine-resolution repeat topographic surveying of dryland landscapes using UAS-based structure-from-motion photogrammetry: Assessing accuracy and precision against traditional ground-based erosion measurements Fine-resolution repeat topographic surveying of dryland landscapes using UAS-based structure-from-motion photogrammetry: Assessing accuracy and precision against traditional ground-based erosion measurements
Structure-from-motion (SfM) photogrammetry from unmanned aerial system (UAS) imagery is an emerging tool for repeat topographic surveying of dryland erosion. These methods are particularly appealing due to the ability to cover large landscapes compared to field methods and at reduced costs and finer spatial resolution compared to airborne laser scanning. Accuracy and precision of high...

Enhancing wind erosion monitoring and assessment for U.S. rangelands Enhancing wind erosion monitoring and assessment for U.S. rangelands
On the Ground Wind erosion is a major resource concern for rangeland managers because it can impact soil health, ecosystem structure and function, hydrologic processes, agricultural production, and air quality. Despite its significance, little is known about which landscapes are eroding, by how much, and when. The National Wind Erosion Research Network was established in 2014 to develop...

Ecohydrological role of biological soil crusts across a gradient in levels of development Ecohydrological role of biological soil crusts across a gradient in levels of development
Though biological soil crusts (biocrusts) form abundant covers in arid and semiarid regions, their competing effects on soil hydrologic conditions are rarely accounted for in models. This study presents the modification of a soil water balance model to account for the presence of biocrusts at different levels of development (LOD) and their impact on one-dimensional hydrologic processes...

Climate change-induced vegetation shifts lead to more ecological droughts despite projected rainfall increases in many global temperate drylands Climate change-induced vegetation shifts lead to more ecological droughts despite projected rainfall increases in many global temperate drylands
Drylands occur world-wide and are particularly vulnerable to climate change since dryland ecosystems depend directly on soil water availability that may become increasingly limited as temperatures rise. Climate change will both directly impact soil water availability, and also change plant biomass, with resulting indirect feedbacks on soil moisture. Thus, the net impact of direct and...
