               (PHRAGMITO-MAGNOCARICETEA). These assemblages, linked to
               meso- and eutrophic slow flowing waters, are ascribed to Phragmite-
               tum communis and Typhetum latifoliae (PHRAGMITION COMMUNIS)
               and MAGNOCARICION ELATAE (Caricetum hispidae). The muddy
               and shallow river banks are often covered by Helosciadetum nodiflo-
               ri and Nasturtietum officinali (GLYCERIO-SPARGANION) and spe-
               cies-poor assemblages referred to MOLINIO-ARRHENATHERETEA
               and MENTHO LONGIFOLIAE-JUNCION INFLEXI.
                  Only few small temporary ponds occur in this area. Some of them host
               communities ascribed to POTAMETEA PECTINATI and RANUNCU-
               LION AQUATILIS. More in detail, Ranunculetum baudotii occurs at Favi-
               gnana, while a little temporary pond located SE of Mt. Cofano hosts both
               Ranunculetum peltati and Lemnetum gibbae (LEMNETEA). As concerns
               ISOËTO-NANOJUNCETEA, some simplified aspects of ISOËTION occur
               on the Egadi Islands (Levanzo and Marettimo) and in the northern sector
               of Zingaro reserve, the association Elatinetum macropodae is recorded for
               Favignana, while species-poor assemblages ascribed to VERBENION SU-
               PINAE are known for some disturbed ponds and rockpools of Marettimo,
               Favignana, and near the coast W of Mt. Cofano.
                  Several fragments of Vitex agnus-castus-dominated riparian scrub
               (NERIO-TAMARICETEA) occur along the stony seasonal streams
               between Castellamare del Golfo and San Vito Lo Capo (e.g. Guida-
               loca, near the village of Scopello, Zingaro reserve, near the touristic
               village of Cala ’mpiso). Most of these watercourses are covered with
               Calystegio sylvaticae-Arundinetum donacis, a sciaphilous-nitrophilous
               reed community ascribed to EPILOBIETEA ANGUSTIFOLII-CON-
               VOLVULETALIA  SEPIUM,  often intermingled with dense  and  al-
               most pure populations of Rubus ulmifolius.
                  Anthropogenic vegetation
                  Local arable crop fields on neutral sandy-loamy soils host plant
               communities  ascribed  to the alliance  RIDOLFION SEGETI,  that of
               base-rich soils to ROEMERION  HYBRIDAE,  the vegetation of vi-
               neyards, orchards and groves is represented by associations of the
               alliance  FUMARION WIRTGENII-AGRARIAE (e.g.  Diplotaxietum
               vimineo-erucoidis at Marettimo), while the annual crop cultures irri-
               gated during summer (e.g. Amarantho graecizanti-Cyperetum rotundi at
               Favignana) belong to DIPLOTAXION ERUCOIDIS.
