Climate change and drought are taking a toll on pinyon pine and juniper woodlands, especially in the southwestern U.S. Dr. Miranda Redmond, an assistant professor at Colorado State University, has researched this ecosystem. She is this week’s Naturalist Nights speaker and talked with KDNK’s Amy Hadden Marsh about the pinyon pine and why it’s disappearing. Dr. Miranda Redmond will be at Carbondale’s Third Street Center Wednesday at 5:30 PM.
