ABSTRACT
In order to examine the effect of slope differences on fern diversity, we chose 10 plots (5×5 m2 for each plot) on east-, west-, south-, and north-facing slopes, with altitudes ranging from 20 to 986 m in Gu-doushan Nature Reserve, Xinhui, Guangdong, China. We obtained the following results: (1) Species abun-dance on the east- and north-facing slopes were high, while that on the west- and south-facing slopes were low. (2) Similarity indices of ferns in different slope orientations were low (
