On Saturday, February 20 from 10:00 to 1:00, Jim O’Donnell guided a group on a Bull Creek Preserve permit hike. He told us about the history of the preserve and ongoing efforts to maintain and enhance this important habitat for the endangered Golden Cheeked Warbler and Black Capped Vireo, explaining the process of capturing and banding birds to monitor their success and dispersal. He talked about bird, mammal, and invertebrate species that have been observed in the preserve and pointed out many native plant species, telling stories of their historical uses. He also identified invasive non-native species, describing the Sisyphean efforts to keep them under control. He showed us the upturned soil where feral hogs had been rooting. Noting the damage that has been done when people create adventitious trails that exacerbate the erosion problem, Jim observed that “although it looks rugged, this land is really quite fragile.”
