Khun Korn Waterfall Forest Park is situated in Muang District, Chiang Rai Province, and covers a mountainous area of approximately 18 square km at 625-1,635 metres above mean sea level. An enumeration of the pteridophytes of this forest park is presented. This is the first report for the area and includes 154 species and 11 infraspecific taxa in 24 families and 66 genera. Collecting has also resulted in two new records, i.e. Selaginella ciliaris (Retz.) Spring (Selaginellaceae) and Dicranopteris linearis (Burm.f.) Underw. var. montana Holttum (Gleicheniaceae) for the flora of Thailand. Furthermore, unusual distributions of fourteen pteridophyte species were discovered. Comparison with other protected areas in the vicinity showed a high diversity in this plant group. However, two endemic fern species originally collected from Chiang Rai province could not be found from this area, and has probably been extispated from the country. Undoubtedly, habitat degradation through human activity has reduced pteridophytes diversity in the park.
