Most park naturalists in general are tasked with developing and conducting interpretive programs for either local, state, or national parks. These programs are focused on the historical or natural features of the park. The natural areas within San Antonio have two Education Coordinators that facilitate this need, so the majority of my job consists of managing plant communities to maintain maximum species diversity. Most of this work targets non-native, invasive plants. I also monitor rare and endangered species like the bracted twistflower, the golden-cheeked warbler, and the black-capped vireo. I conduct surveys on these species as well as on karst/cave features to satisfy U.S. Fish and Wildlife Service requirements. Finally, I help manage wildlife at the park including certain bird species and feral hogs.
