Alcara Li Fusi fortresses

Site type: SAC - Special Conservation Area

Code: ITA030013 - Hectares: 2183


The site in question is characterized by Mesozoic carbonate outcrops that form spectacular rocky walls surmounted by impervious ridges, which give this part of the Nebrodense territory a remarkable landscape peculiarity. The highest peaks are between 1110 and 1300 m. This limestone massif rests on a siliceous base represented by flysh and schists. The climate of the area is comprised between the mesomediterraneo and supramediterraneo with a subhumid ombroclimate. The most important vegetational aspects are represented by the rocky or semi-rupestrian habitats colonized by casmophilous communities rich in endemics that prefer more or less vertical walls. On the crests and on the rocky slopes a scrub is found at Euphorbia dendroides. The forest aspects are represented by mixed woods with Quercus ilex and Ostrya carpinifolia, which at lower altitudes are replaced by thermophilic formations with Quercus virgiliana. On the siliceous substrates are found strips of woods with Quercus suber or Quercus gussonei. The most common aspects of degradation are the Ampelodesmos mauritanicus meadows, limited to limestone substrates, and thorny bushes widespread above all on siliceous substrates. The extensive breccias beneath the rock faces are colonized by glareic pioneer aspects with small bushes.

This area is affected by Mesozoic carbonate outcrops that host very peculiar plant communities and normally absent in the rest of the Nebrodi chain. In fact, these are mostly vegetational aspects linked to calcareous environments represented by chasmophilous, glareicolous and semi-rupestrian associations. However, there are also silicicular aspects widespread in the rest of the Nebrodense area. Due to these peculiarities, the Rocche del Crasto are to be considered as one of the most singular and spectacular Nebrodense landscapes, also in relation to their uniqueness. once mentioned in the list reported in section 3.3 (D) .The cliffs and rocks represent actual or potential nesting sites for numerous species of Raptors, while the cavities are home to invertebrate fauna of considerable scientific and biogeographical significance
