Since the 1900s, research staff, visiting scientists, and interns have documented the biodiversity of the Shawangunk Ridge as part of our “living laboratory" in order to protect and perpetuate life on the Preserve’s lands. While much of these data were collected in standardized study designs, a large amount of data was collected stochastically and documented passively in our records and archives. This dataset provides these passive biodiversity records to support biodiversity research and inform environmental management and ecological sciences.
