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.

Stanislaus National Forest

Located North and West of Yosemite National Park, the Stanislaus encompasses over 848,000 acres of land.


Sierra National Forest stretches from the Merced River all the way to the northern reaches of Kings Canyon.


Thousands of visitors travel through Sequoia National Forest each year on their way to Kings Canyon and Sequoia National Parks.


To Foster a Better Understanding of these Forests


Education lies at the heart of 3FIA’s mission. Our live forest presentations have entertained and informed thousands of forest visitors. Educating the public on the natural and human history, science, and unique value of our public lands is key to sustaining these forests for future generations.


The Stanislaus, Sierra, and Sequoia National Forests are part of America’s national forest heritage. These lands were gifted to all of us thanks to the wise decisions and actions of earlier generations. It is our responsibility to make sure future generations can also experience the beauty and abundance of these public lands.


3FIA advocates for the programs and seven principles of Leave No Trace, a world leader in teaching minimum impact skills to adults and young people. We work to foster a code of ethics for outdoor use to help preserve and maintain the health of our forests.
