Ferns of Hawaii National Park

The booklet offers an illustrated, visitor-focused guide to the park's ferns, surveying species from tiny filmy forms to towering tree ferns and explaining fern reproduction by spores and typical habitats. It emphasizes identification by abundance with photographs, scale references, and a concordance of scientific names, and highlights notable groups such as tree ferns with their pulu fibers, the amaumau and amau, and other common species. Practical notes on collecting, conservation concerns, trail-accessible locations, and a selected bibliography support further study.
