Fig. 4. Species richness of vascular plants in relation to plot area (Log A) in Jeoji Gotjawal and Seonheul Gotjawal in Jeju Island. The bars represent the average species richness across various plot sizes, and the vertical lines on the bars indicate the standard deviation. Uppercase letters represent differences in species richness among plots within Jeoji Gotjawal, and lowercase letters represent differences among plots within Seonheul Gotjawal. An asterisk (*) indicates significant differences in species richness between the two regions within the same plot size.
