Abstract

This study aims to determine the diversity of fern vegetation in the Sangkulirang- Mangkalihat karst area of Berau and East Kutai Regency. The research was carried out for two months in six locations. The plotting method used the purposive sampling method, with a plot size of 10 m x 10 m as many as 15 at each location. The research location of the karst area of Sangkulirang – Mangkalihat was found 4,871 individuals from 55 species, 39 genera, and 23 families. The most abundant species is Selaginella willdenowii (Desv. ex Poir.) Baker. Diversity Index (H’) was ranging from 1.37 to 2.36. Dominance Index (C) in all research locations closed to 0, so it can be said that there were no dominant species in each location. Evenness Index (e) in Biatan Ulu was more than 0.96, while other locations were more than 0.51. Similarity Index (ISs) in all study locations was less than 50%, so it means that all species in each location are different.
