Study Reveals the Importance of Ancient Trees A recent study led by the University of Barcelona sheds light on the critical role played by the oldest trees in protecting endangered species in forest ecosystems. Published in the journal Proceedings of the National Academy of Sciences USA (PNAS), the study underscores how preserving ancient trees is essential for biodiversity conservation amid the challenges posed by global environmental changes. Ancient Trees Provide Shelter for Endangered Species The research focuses on the wolf lichen (Letharia vulpina), an endangered species prevalent in mature forests and long-lived trees. Specifically, the study highlights the symbiotic relationship between the wolf lichen and the oldest trees, such as the black pine (Pinus uncinata) in the high mountains of the Pyrenees. These ancient trees serve as life shelters for the wolf lichen, offering unique physiological characteristics and habitats conducive to its survival. Threats to Ancient Trees and...
