The finding of the cyanolichens Coccocarpia
and Leptogium only in plot 1 indicates that plot 1
still has a good air quality, since cyanolichens are
sensitive to acidification from air pollution (Cameron
& Richardson 2006). This data was supported with
a dendrogram of location cluster which analyzed by
MEGA 5.05 with UPGMA method (unpublished
data). The dendrogram showed a location cluster of
Coccocarpia and Leptogium that was far apart from
other location clusters (cluster of Canoparmelia and
Pyxine, cluster of Physcia, and cluster of Parmotrema
and Dirinaria) with about 36% of location cluster
distance. To compare, cluster of Canoparmelia and
Pyxine was closer separated from the last two location
clusters with about 22% location cluster distance.
