The Sequoia Field Institute (SFI) is a department of the Sequoia Natural History Association (SNHA). SNHA is a non-profit membership organization dedicated to supporting education, interpretation, research, and the natural and historic preservation of Sequoia and Kings Canyon National Parks and surrounding public lands. The Association is committed to enriching the experiences of visitors and promoting public awareness of the significance of National Parks through educational programs, publications and financial support.

SNHA and SFI mission statement:
To enhance understanding and appreciation of Sequoia and Kings Canyon National Parks and surrounding public lands.

We believe that there is a never-ending flow of people who need to be exposed to the values of the National Park Service. That the more people are exposed and educated about the natural world, the more they will appreciate it and realize the necessity to protect it. That no matter how much an expert someone becomes on our Parks, that person can learn more, appreciate more, and further support the Parks' protection. If a picture is worth a thousand words, then a trip to a natural area is beyond measure.
