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 quantitative soil-geomorphic framework for developing and mapping ecological site groups A quantitative soil-geomorphic framework for developing and mapping ecological site groups
Land management decisions need context about how landscapes will respond to different circumstances or actions. As ecologists’ understanding of nonlinear ecological dynamics has evolved into state-and-transition models (STMs), they have put more emphasis on defining and mapping the soil, geomorphological, and climate parameters that mediate these dynamics. The US Department of...

Parameterizing an aeolian erosion model for rangelands Parameterizing an aeolian erosion model for rangelands
Aeolian processes are fundamental to arid and semi-arid ecosystems, but modeling approaches are poorly developed for assessing impacts of management and environmental change on sediment transport rates over meaningful spatial and temporal scales. For model estimates to provide value, estimates of sediment flux that encapsulate intra- and inter-annual and spatial variability are needed...

What determines the effectiveness of Pinyon-Juniper clearing treatments? Evidence from the remote sensing archive and counter-factual scenarios What determines the effectiveness of Pinyon-Juniper clearing treatments? Evidence from the remote sensing archive and counter-factual scenarios
In the intermountain western US, expansion of Pinyon (Pinus edulis) and Juniper (Juniperus spp.) woodlands (PJ) into grasslands and shrublands is a pervasive phenomenon, and an example of the global trend towards enhanced woody growth in drylands. Due to the perceived impacts of these expansions on ecosystem services related to biodiversity, hydrology, soil stability, fire prevention...

Oil and gas reclamation on US public lands: How it works and improving the process with land potential concepts Oil and gas reclamation on US public lands: How it works and improving the process with land potential concepts
• There are three general stages of a well's life on US public land: 1) the permitting process to drill, 2) active extraction of fossil fuel resource, and 3) plugging and abandonment of well. • There is no national standard for oil and gas reclamation in the United States similar to mining and therefore current reclamation practices and standards fail to achieve long-term effectiveness...

Sampling design workflows and tools to support adaptive monitoring and management Sampling design workflows and tools to support adaptive monitoring and management
On the Ground • Adaptive land management requires monitoring of resource conditions, which requires choices about where and when to monitor a landscape. • Designing a sampling design for a monitoring program can be broken down in to eight steps: identifying questions, defining objectives, selecting reporting units, deciding data collection methods, defining the sample frame, selecting an...

Drought resistance and resilience: The role of soil moisture–plant interactions and legacies in a dryland ecosystem Drought resistance and resilience: The role of soil moisture–plant interactions and legacies in a dryland ecosystem
In many regions of the world, climate change is projected to reduce water availability through changes in the hydrological cycle, including more frequent and intense droughts, as well as seasonal shifts in precipitation. In water-limited ecosystems, such as drylands, lower soil water availability may exceed the adaptive capacity of many organisms, leading to cascading ecological effects...
