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.

Life history characteristics may be as important as climate projections for defining range shifts: An example for common tree species in the intermountain western US Life history characteristics may be as important as climate projections for defining range shifts: An example for common tree species in the intermountain western US
Aim Predictions of future suitable habitat for plant species with climate change are known to be affected by uncertainty associated with statistical approaches, climate models and occurrence records. However, life history characteristics related to dispersal and establishment processes as well as sensitivity to barriers created by land‐use may also play important roles in shaping future

Beyond traditional ecological restoration on the Colorado Plateau Beyond traditional ecological restoration on the Colorado Plateau
The Colorado Plateau is one of North America's five major deserts, encompassing 340,000 km2 of the western U.S., and offering many opportunities for restoration relevant to researchers and land managers in drylands around the globe. The Colorado Plateau is comprised of vast tracts of public land managed by local, state, and federal agencies that oversee a wide range of activities (e.g...

Landsat time series analysis of fractional plant cover changes on abandoned energy development sites Landsat time series analysis of fractional plant cover changes on abandoned energy development sites
Oil and natural gas development in the western United States has increased substantially in recent decades as technological advances like horizontal drilling and hydraulic fracturing have made extraction more commercially viable. Oil and gas pads are often developed for production, and then capped, reclaimed, and left to recover when no longer productive. Understanding the rates...

Soil water dynamics at 15 locations distributed across a desert landscape: insights from a 27‐yr dataset Soil water dynamics at 15 locations distributed across a desert landscape: insights from a 27‐yr dataset
Desert ecosystems are primarily limited by water availability. Within a climatic regime, topography, soil characteristics, and vegetation are expected to determine how the combined effects of precipitation, temperature, and evaporative demand of the atmosphere shape the spatial and temporal patterns of water within the soil profile and across a landscape. To forecast how desert...

Insights from long-term ungrazed and grazed watersheds in a salt desert Colorado Plateau ecosystem Insights from long-term ungrazed and grazed watersheds in a salt desert Colorado Plateau ecosystem
Dryland ecosystems cover over 41% of the earth’s land surface, and living within these important ecosystems are approximately 2 billion people, a large proportion of whom are subsistence agropastoralists. Improper grazing in drylands can negatively impact ecosystem productivity, soil conservation, hydrologic processes, downstream water quantity and quality, and ultimately human health...

Identifying optimal remotely-sensed variables for ecosystem monitoring in Colorado Plateau drylands Identifying optimal remotely-sensed variables for ecosystem monitoring in Colorado Plateau drylands
Water-limited ecosystems often recover slowly following anthropogenic or natural disturbance. Multitemporal remote sensing can be used to monitor ecosystem recovery after disturbance; however, dryland vegetation cover can be challenging to accurately measure due to sparse cover and spectral confusion between soils and non-photosynthetic vegetation. With the goal of optimizing a...
