The lichens in a relic wood of Juniperus turbinata Guss. with a new record for Sicily 801
About the 30% of terrestrial species list are char-
acteristic of xerophytic to very xerophytic environ-
ment (Fig. 13).
The epyphitic flora of Acate (Ragusa, Sicily) is
poor if compared with the surveyed flora on J.
oxycedrus at Campu su Disterru in Sardinia (Zedda
& Sipman, 2001); this difference can be attributed
to different climatic conditions, as shown in the
graphs, more shallows in Acate compared to humid
conditions and the highest altitude of Sardinia.
Lichenic flora’s significance of Piano Pirrera
territory, is especially qualitative, in fact among the
reported lichens Heppia adglutinata is new to Sicily
and many species are from extremely rare to rare
for Italy.
