Being found in all plots, Parmotrema and
Dirinaria were showed different population pattern
(Figure 5). Parmotrema showed unclear population
pattern. Thallus number and average coverage of
Parmotrema were the highest in plot 2 (TN = 16, AC
= 11.84 cm2), but equally smaller in both plot 1 (TN
= 6, AC = 1.002 cm2) and plot 3 (TN 2, AC = 2.42
cm2). Dirinaria showed a clear pattern of increasing
TN from plot 1 to plot 2 and plot 3, and decreasing
AC from plot 1 to plot 2 and plot 3.
