history

Mariton was assembled over many years by Mary and Tony Guerrero, who wanted to protect the land and the wildlife living there from development. They also wanted the property to serve as an environmental education center for local schools, colleges, and the greater community. In 1969, they established Mariton Wildlife Sanctuary and Wilderness Trust; the name Mariton was a combination of their first names.

In 1992, the Trust entered into a long-term agreement for Natural Lands to manage the property. Today, Mariton is still serves as an educational resource, honoring the Guerroro family’s legacy.
