Great Hollow

Established in 2016, the Great Hollow Nature Preserve & Ecological Research Center is a 501(c) 3 non-profit organization that is dedicated to biodiversity conservation, applied ecological research, experiential environmental education, and passive outdoor recreation. Our staff and collaborators conduct integrative, conservation-driven studies of wildlife and plants within and beyond our preserve. Great Hollow also runs numerous education programs for both children and adults throughout the year, including school programs and a nature-based summer day camp. Our 825-acre preserve and five miles of hiking trails are open to the public year-round for the exploration and enjoyment of nature.
