Island of Leeks
Site type: SAC - Special Conservation Area
Code: ITA080005 - Hectares: 16
The SCI, covering 1.27 Ha, falls within the territory of the municipality of Ispica. The climate of the area, according to the Rivas Martinez criterion, adapted to Sicily by Brullo & al. (1996), is
Lower dry lower thermomediterranean, however rather humidified by the breezes and by the intense evaporation of the surrounding liquid medium.
has a flat and compact limestone sandstone surface with Limonietum physiognomically dominated by Limoniastrum monopetalum. On one edge they are
limestone sands from erosion are present. The presence of Limonium sinuatum appears strong, a species present for Italy only along the coasts of southern Sicily.
Muscari gussonei already indicated in the previous draft of the sheet does not appear anymore (but this is not supported by literature data). The sands that
they should have hosted this species appear with incipient dune characters and are dominated by Elymus farctus.
It is an islet close to the shore mainly affected by halophilous rock vegetation. In winter it is used by Phalacrocorax carbo
Cormorant as a dormitory, mainly affected by halophilous rock vegetation.Despite the absence of the previously reported Muscari gussonei, the Isola site
dei Porri appears to be of good environmental value, as a rare case of an area not subjected to anthropic disturbance. Its environmental value is intensified by the
presence of the rare Limoniastrum monopetalum and the equally rare Limonium sinuatum. An element of great naturalistic value is given by Cichorium
spinosum, rare suffruticosa camefite with steno-Mediterranean distribution, but for the Italian floristic sector present only in the Maltese archipelago and along the coasts
of south-eastern Sicily. Also of interest is the presence of the halophyte Aeluropus lagopoides, a typical plant of the salt pans.
