Palombieri quarry (ITA090017)

Site type: SAC - Special Conservation Area 

Code: ITA090017 - Hectares: 552


The site falls within the territory of the municipality of Modica. The soils are mosaics of degraded brown soils and Mediterranean red soils. The substrates consist of limestone
tertiary compacts of the Plateau Ibleo series.The climate is dry thermo-Mediterranean according to the terminology of Rivas Martinez.Present chasmophilic aspects (8210),
ephemeral meadows afferent to the Thero-Brachipodietea (6220), aspects of thermo-Mediterranean vegetation in Euphorbia dendroides and Chamaerops humilis (5330),
oak woods with Quercus ilex and their degraded aspects (9340). Formations of the drippings (7220). Casmophytic formations afferent to the
Dianthion rupicolae Brullo & Marcenò. On the semi-rugged slopes unsuitable for agricultural crops there have always been and still are afferent holm oak woods
to Quercetea ilicis and their degraded forms, also of great interest, which can be framed in the Oleo-Ceratonion alliance or in the thorny shrub formations of the
Crataego-Prunetea. The valley floor is very disturbed due to past crops (today mostly abandoned) with clear nitrophilic aspects and
4.2 Quality and importance
The site is of considerable wildlife interest above all for the permanent presence of the Lanner. However, it also hosts an interesting freshwater invertebrate fauna
From a floristic and vegetational point of view, the site has a great naturalistic value, both for formations that characterize it and for the individual species
including a high percentage of endemics. In addition to the presence of oaks in Q. ilex, which here in the calcareous semi-rocky environment find the maximum
expressiveness, there are shrub formations derived from the degradation of oaks to holm oaks. Particularly worthy of attention for the value either
both landscaped and naturalistic are the communities belonging to Oleo-Euphorbetum dendroidis and Rubo-Aristolochietum altissimae with the endemic Aristolochia
The rocky walls are home to the Putorio-Micromerietum microphyllae association, also rich in endemics such as Putoria calabrica, Micromeria
microphylla, Trachelium lanceolatum, Antirrhinum siculum, Dianthus rupicola, Silene fruticosa, Calendula suffruticosa subsp. suffruticosa.
