Connecting People with their National Forests

Interpretive Resources for California’s Stanislaus, Sierra, and Sequoia National Forests
Follow 3FIA on Instagram.

Three Forests Interpretive Association [3FIA] is a non-profit educational organization that helps to inform and educate visitors to California’s Stanislaus, Sierra, and Sequoia National Forests. Our goal is to aid in promoting an appreciation and understanding of these forests, and to assist the US Forest Service in its mission to conserve these public lands. We publish and distribute books, brochures, maps and other materials relating to the human and natural history of the Sierra Nevada. Profits from these activities are used to help the Forest Service fund a wide range of interpretive and educational programs, contributing to the public’s appropriate use and enjoyment of these precious resources. 3FIA believes that an informed public can aid in the conservation mission of the Forest Service.
