What if some of the most complex and beautiful life forms in North Texas were hiding in plain sight right under your feet? In this flagship episode of the Dallas Nature Channel, we venture to the Southwest Nature Preserve in Arlington to explore the vibrant, alien-like world of lichens. From the “Golden Eye” to the “Stonewall Rim,” discover why these organisms are much more than just “spots on a rock.”
We are honored to be joined by Dr. Manuela Dal Forno, a leading voice in lichenology currently with the Botanical Research Institute of Texas (BRIT). With a Ph.D. and a postdoctoral fellowship from the Smithsonian National Museum of Natural History, Dr. Dal Forno brings world-class academic insight to the DFW landscape. Watch as she breaks down the three main growth forms—Foliose, Fruticose, and Crustose—and explains the fascinating “sunscreen” chemistry that allows lichens to survive the harsh Texas sun.
Filmed in stunning 4K, this video is designed for North Texas hikers, master naturalists, and curious explorers alike. Whether you are walking the trails at Southwest Nature Preserve or exploring your own backyard in Dallas or Fort Worth, you will never look at a sandstone boulder the same way again. Grab your hand lens and join us for a deep dive into the resilient beauty of DFW’s lichens.
