Our Mission

Founded in 1999, the Waltham Land Trust’s mission is to create a legacy of land conservation in Waltham by promoting, protecting, restoring, and acquiring open space with a community of volunteers and a small staff that operates with mutual respect and goodwill towards each other. Recognizing that diversity strengthens our organization, the Waltham Land Trust strives to create an environment where everyone is respected, valued, and appreciated regardless of their race, gender, age, sexual orientation, religious beliefs, abilities, or disabilities. We welcome those who share these values.

The Waltham Land Trust envisions growth in public appreciation of natural resources, preservation and restoration of native habitat, and increased biodiversity to foster a healthier environment.
