We thank Bill Buck, Carol Carollo Matos, Zaac Chaves, Roy Halling, Dick Harris, Gary Lincoff, and Robbin Moran for their contributions to the inventory; Sharon Ali, Cindy Hirsch, and Nicole Tarnowski for training interns to prepare our specimens for archiving in the herbarium at the New York Botanical Garden; Michael Rothman for imaging plants in the field; and Melissa Tulig and Joel Ramirez for constructing the framework of the site. We offer special thanks to The New York Botanical Garden for supporting our research and recognize Paul Zofnass, his family, and many others for having the foresight to establish this preserve for present and future generations.
