Hawai'i Natural History Association is a National Park Service cooperating association, a nonprofit organization authorized by Congress to support the interpretive, educational, scientific and historic mission of the National Park Service. Proceeds from the sale of educational items in our outlets in park visitor centers and this Web site are returned directly to the Park Service to support interpretive programs, research projects, museum activities, free publications, cultural demonstrations, and other related activities. We also maintain a small publications program, producing our own books, guides, videotapes, posters and other items.
