The Preserve

The Marguerite Gahagan Nature Preserve is a 501(c)(3) non-profit organization dedicated to the lifelong mission of conservationist Marguerite Gahagan. Her former estate now serves as a public wildlife sanctuary and is open to the community for hiking, biking, and sightseeing. The 60-acre property hosts a rich mosaic of habitats and features 2.5 miles of walking trails, including a wheelchair-accessible asphalt path.

Environmental Education

Since 2001, Gahagan has provided exceptional opportunities in environmental and natural science instruction to students and communities in a seven-county area. Over the last sixteen years, these lessons and activities have been developed into four distinct programs. Click here to read more:

  • School Field Trips: Grade level specific, on-site programming using the forest, wetlands and pond resources of the property.

  • The Visiting Naturalist: In-school presentations using extensive resource kits developed primarily by our education director.

  • Environmental Learning for Future: Training for parents and teachers to use our environmental educational materials in school classrooms.

  • Nature Camp: Every July, Gahagan holds a summer day-camp that promotes scientific inquiry and an appreciation for nature and the outdoors in students ages 7-11.
