Diversity and distribution pattern of ferns at Bukit Larut, Taiping, Malaysia

Abstract

In this preliminary study, the ferns diversity and richness were assessed at Bukit Larut, Taiping, Malaysia. This was done to understand the pattern of distribution of the ferns and their conservation statuses. Plots of size 10 x 10 m were established at different elevations along the hill using a preferential Random Sampling method and ensuring a minimum distance of 20 m between each plot. Although there were variations in the ferns diversity and richness with regards to the different elevations studied, the base of the hill was still more diverse in ferns (Shannon index = 1.28 and Margelef index = 1.27). Fifteen ferns belonging to 10 families were identified in all the sampled plots. Dicranopteris linearis was observed to be weedy and more abundant. Terrestrial ferns were reported to be the most common and abundant in this hill forest. This is an indication of less-disturbed nature of the forest.
