Natural History Collections

The Daniel Smiley Research Center (DSRC) – Mohonk Preserve’s conservation science unit – is recognized nationally and beyond for its extensive collection of long-term research data, including 86 years of natural and cultural history observations, 123 years of daily weather data, 60,000 physical items, 9,000 photographs, and research library. Of those physical items, there are over 3,000 herbarium specimens, 139 mammal specimens, 107 bird specimens, 140 butterfly specimens, 400 arthropod specimens, and over 10,000 index cards with handwritten and/or typed natural history observations. Some cards contain a single entry but most contain multiple entries, meaning the total number of data points is much higher. The data and natural history collections support the Preserve’s land management and stewardship activities and our educational programming. The collections are also frequently cited in research on climate change, biodiversity, bird migration, and human impact on the environment.
