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.

In this episode we spoke with Dr. Flavie Audoin, an Assistant Professor in the School of Natural Resources and the Environment at the University of Arizona and Assistant Rangeland Management Specialist for the UA Cooperative Extension. Dr. Audoin’s research examines solutions for livestock producers who are seeking to raise animals and manage rangelands in a sustainable way. She talked with us about how targeted grazing can help minimize invasive plants and reduce wildfire risk, and shared the potential benefits and drawbacks of new virtual fence technology.

Happy New Year! In this first episode of 2026, we spoke with Dr. Sarah Whipple, a Climate Adaptation Service Scientist and biologist with the Climate Adaptation Technical Services (CATS) initiative of the USGS National Climate Adaptation Science Center. Dr. Whipple, who has expertise in pollinator biology, inventory and monitoring, discussed the importance of pollinators and explained the impact of a shifting landscape and climate on species that are important for agriculture, food security and resilience. Listen to learn more about Sarah and her research!

Happy Holidays! In this episode we talked to Max Wade, the owner of Galloping Goat Grazing, and Michael "Scial" Scialdone, Bosque Project Manager with the Pueblo of Sandia Environment Department. Max and Scial explained how utilizing goats for targeted grazing allows problematic vegetation to be removed, and can help reduce the risk of devastating wildfires in our wildland/urban interfaces.

Dr. Charlie Clements leads the Great Basin Rangeland Research Unit of the United States Department of Agriculture (USDA) Agricultural Research Service, where he conducts research on the restoration of ecologically threatened rangelands. He and his team aim to conserve and enhance sustainable agricultural production, natural resources and communities. He also explores science-based solutions to reduce the spread of harmful invasive species in the region, especially cheatgrass (also called brome.)

According to the U.S. Department of Agriculture, three fourths of the world's flowering plants and about 35 percent of the world's food crops depend on pollinators to reproduce. We interviewed Melanie Kirby and Davon Collins to learn more about the beekeping program at the Institute of American Indian Arts in Santa Fe, NM.
