Keystone Society

Deepen Your Impact at Bernheim

Bernheim Forest and Arboretum is more than a place to visit. It is a living legacy—more than 16,000 acres of forests, wetlands, waterways, and open spaces protected for people and nature. It is a place where conservation happens, where people discover the natural world, and where generations can find connection, inspiration, and renewal.

Keystone Society members are a community of philanthropic supporters who make a deeper investment in Bernheim’s mission of connecting people with nature.

Your Support Makes a Difference

When you become a Keystone Society member with a gift of $1,000 or more, your generosity provides critical support where it is needed most.

Your investment helps Bernheim:

• Protect and restore wild places — caring for forests, waterways, wildlife habitat, and the diverse species that depend on them.
• Connect people with nature — creating opportunities for children, families, students, and adults to learn, explore, and build lasting relationships with the natural world.
• Advance conservation and research — supporting the science, stewardship, and partnerships that help Bernheim protect a healthy and resilient landscape.
• Care for a living legacy — preserving Bernheim’s forests, trails, arboretum, art, and other resources for generations to come.

Keystone Society members receive all the benefits of Bernheim membership, along with additional opportunities to engage more deeply with the forest and its mission. See your impact in action with special benefits and invitations to become more deeply connected to the work you sustain:

• Schedule a custom tour to explore areas of the forest and projects beyond the typical visitor experience with Bernheim leadership
• Learn about current and future initiatives directly from Bernheim staff and leadership at the annual State of the Forest presentation
• Gather with fellow supporters who share your commitment to protecting and connecting people with nature in the Forest Lounge at CONNECT
• Welcome a household of new members of your choice into the Bernheim community with a gift membership

The Keystone Society recognizes donors who make an annual investment of $1,000 or more that strengthen Bernheim’s conservation, horticulture, environmental education, Arts in Nature, and Children at Play Network initiatives.
