In this episode, we spoke with Roy Petrakis, a Geographer with the U.S. Geological Survey (USGS) Western Geographic Science Center. Roy’s expertise includes using remote sensing and GIS to understand how landscapes in the southwest are changing over time, including shifts in wildfire behavior, vegetation dynamics, and water availability. His research addresses wildfire and fuel treatments, climate variability, watershed management, and more.

He talked with us about the long-standing partnership between the San Carlos Apache Tribe and the USGS, where collaborative research supports land management decisions and riparian restoration efforts. From tracking invasive species like tamarisk to studying wildfire impacts and drought stress, Roy highlights how science and Indigenous knowledge come together to build more resilient ecosystems and support communities.

In this episode, we spoke with Dr. Camille Stevens-Rumann, interim director of the Colorado Forest Restoration Institute at Colorado State University and associate professor in the Department of Forest and Rangeland Stewardship. Dr. Stevens-Rumann’s research focuses broadly on disturbance ecology, including post-fire forest recovery. She examines how ecosystems respond to disturbances like wildfire, to help improve restoration and management strategies. She shares how fire regimes in the western U.S. are changing, what drives extreme wildfire events, and how the presence of a specific type of tree can help mitigate fire risk.

A snow drought happening across the western U.S. is creating dramatic shifts. In this episode, we spoke with Dr. McKenzie Skiles, Director of the Snow Hydrology Resarch-to-Operations Laboratory (Snow HydRO Lab) and associate professor at the School of Environment, Society & Sustainability at the University of Utah. Dr. Skiles specializes in snow monitoring, modeling and remote sensing, and investigates the impacts of mineral dust and other light-absorbing particles on snow. She explained why changing snowfall and snowmelt patterns have implications for recreation and water security in the west.
