As photosynthesis happens, trees take in carbon from the atmosphere and store it in the form of sugars or carbohydrates.  These sugars can be stored for many years in trees as a sort of “memory” and used to support their growth and metabolism during times of stress, like a drought.  We talk with Drew Peltier, ecophysiologist and professor at the University of Nevada, Las Vegas.  Drew’s interests and research center on understanding how climate influences tree growth in our changing environment.

Dr. Karletta Chief, Director of the Indigenous Resilience Center at the University of Arizona, leads initiatives for Tribal water security and community-driven climate solutions. Dr. Chief, a Diné hydrologist and professor, shares how growing up in Black Mesa on the Navajo Nation has influenced her current work. She emphasizes the importance of utilizing traditional knowledge alongside western science, and ensuring Indigenous communities’ central role in decision-making. We learn about the powerful mission of the Indigenous Resilience Center, and Dr. Chief shares her hopes for empowering the next generation of Indigenous youth to lead and innovate in their communities.

Charlie Carpenter, a Braided Science Conservationist with IndigenousLed, discusses their work focused on reintroducing buffalo to Indigenous lands. The process of buffalo reintroduction includes land suitability assessments, political hurdles, and funding challenges. The initiative aims to restore buffalo, a keystone species, to their native habitats, benefiting both Indigenous cultures and ecosystems. Charlie highlights the importance of braided science, which integrates traditional ecological knowledge with Western science. We also talk about other upcoming projects including medicinal gardens and intertribal beaver councils.


Return of the Buffalo

It is the mission of the U.S. Geological Survey to monitor water resources across the country.   We talk with Chris Wilkowske, a hydrologist with the USGS at the Utah Water Science Center, about the science and methodology of measuring stream flow. We talk about how stream gauges operate and the process of validating and adjusting data, particularly after events like floods. Local examples from the Moab area and the Colorado River highlight the dual purposes of stream gauges for flood monitoring and groundwater assessments.

This podcast concludes a 3-part series on Moab’s creek corridors.  The series includes restoration processes on the creeks, stream water gauge science, and this episode, fire fuels mitigation along Mill and Pack creeks flowing from the west side of the La Sal Mountains.  Fire risk is high in creek corridors and other overgrown areas. The dense corridors could spread fire quickly through Moab and Spanish Valley.  We talked with Duncan Fuchise, the forest stewardship program manager with the Utah Division of Forestry, Fire and State Lands, as he hopped between work sites along the Mill Creek Corridor one morning in March 2025.


Clearing Out the Fuels

Ryan Barton emphasizes the importance of collaboration and negotiation in solving water issues and bringing resilient water systems to the Navajo Nation.  As a hydrologist working for the Navajo Nation Department of Water Resources,  Ryan has been involved in projects for over a decade including hydrographic surveys, lake capacity studies, and the San Juan River Basin Crop Inventory.  Science Moab talks with Ryan about his most recent and ongoing efforts to successfully provide drinking water to the Westwater community west of Blanding, UT through extensive collaboration among various entities.  Ryan’s path into hydrology has been influenced by family and childhood experiences of nature conservation.

Tony Mancuso is the Sovereign Lands Program Manager for the Green and Colorado Rivers at Utah’s Department of Natural Resources (DNR). His management efforts focus on maintaining the health and navigability of waterways under state jurisdiction, including removing invasive species and restoring natural habitats.  Tony talks about specific projects like the New Rapid and Gold Bar side channels aimed at enhancing fish habitats and wetland environments. He also emphasizes the importance of public education and engaging youth through programs like Science Moab. The discussion highlights the challenges, collaborative efforts, and long-term commitments required in resource conservation and management.
