The Great Hollow Nature Preserve & Ecological Research Center is a nonprofit organization focused on biodiversity conservation, applied ecological research, experiential environmental education, and passive outdoor recreation. It aims to conduct conservation-driven studies on wildlife and plants, while offering various educational programs and maintaining an 825-acre preserve for public exploration.
Great Hollow offers grants up to $5,000 annually to support biological research within its preserve and beyond. A single project can receive up to $2,000. The grant program prioritizes field biology projects with a conservation application, although all areas of field biology are eligible. Great Hollow Nature Preserve can serve as either the sole study site or one of several for the research projects.
