Other Site Characteristics

The Ta' Cenc area, located in the southwest of Gozo, comprises a relatively undeveloped stretch of open land characterised by a number of geomorphological units supporting a conglomeration of natural habitats. In this respect, the Ta' Cenc area is highly influenced by one of the largest fault complex systems of Gozo, where the area is bound by a steep escarpment along its northern periphery and a belt of sheer coastal cliffs to the south.These vertical lower coralline limestone cliffs border the southern half of the site, extending from Ta' Cenc to Il-Bajja ta' Mgarr ix-Xini. The vertical sides support rupestral communities, rich in endemic species.The northern half of the site is characterised by an extensive karstic Globigerina limestone terrain plateau that extends from the western end of Ix-Xaghra l-Kbira in a southeastward direction towards Tal-Kalkara, Il-Qortin iz-Zghir and Ta' Nanas, occupying a central portion of the plateau, and along the southern direction towards Tad-Debda, Ix-Xaghra and Il-Qortin il-Kbir, thus occupying an expanse of land overlooking the cliffs on the western and southwestern sectors. These karst areas are typified by a mosaic of grasslands, ermes, phrygana and pre-desert scrub communities.Formerly cultivated, terraced fields occupy a significant portion of land to the east (as at Is-Sisien, Tal-Kalkara and Tas-Smina) and southeast (at Ta' Riglis, Lizgandlu and Ta' L-Iskandlu). A number of trees (Ficus carica and Ceratonia silqua) and large shrubs also occur on the peripheries in some of the former fields.The steep-sided valley at Wied Sabbara drains a fair extent of the land cover towards the eastern side. Wied Sabbar shows a mosaic of natural communities; dominated by Euphorbia dendroides or Hypericum aegypticum on the steep sides, watercourse vegetation along the valley bed, and archaeophytic assemblages.The Ras in-Newwiela promontary forms a flat Globigerina Limestone cliff-top platform that is colonised by maritime steppe communities, dominated by Lygeum and Stipa.Note on 'Other Land': the other land comprises mainly areas with rockpools and temporary ponds.

4.2 Quality and importance

Within this site, the open karstic plateau is characterised by relatively shallow soils colonised by various grassland, phrygana and pre-desert scrub assemblages. This area in general supports a wide range of flora and fauna that include various reptiles; small mammals, including Atelerix algirus; and various invertebrate groups, including the endemic Armadillidium schmalfussi, Stenosis melitana, Tentyria laevigata leachi and Pimelia rugulosa melitana.The areas from Fuq tal-Gruwa/Ix-Xaghra l-Kbira to Ta' Nanas consist mostly of phrygana and steppic assemblages, which also include flora and fauna of interest, including the endemic molluscs Muticaria macrostoma oscitans, and Trochoidea spratti. The Ta' Nanas area also houses a relatively large but localised population of the sub-endemic Scilla sicula, as well as fairly extensive patches dominated by Brachypodium retusum.The phrygana communities (5410) of Ta' Cenc extend throughout the northern escarpment that defines the northern boundary of the area, from Fuq tal-Gruwa to Il-Hamra, extending partly to Il-Qortin iz-Zghir. This habitat type is characterised by Anthyllis hermanniae and labiate shrubs, particularly Thymus captitatus. Anthyllis hermanniae also occurs in other areas, as at Ix-Xaghra l-Kbira, but does not characterise the habitat type, which is mostly typified by various annuals and other plants typical of the Mediterranean xeric grasslands (6220), but also including andropogonid grasses, as Hyparrhenia hirta.These xeric grassland habitats (6220) can be found nearly throughout the entire Ta' Cenc area, although the status of its distribution and conservation varies. The areas near Il-Qortin iz-Zghir and Ta' Nanas host grasslands in a good conservation status, whereas the grasslands in other areas, such as at Ix-Xaghra and Il-Qortin il-Kbir, are more disturbed. Thermo-Mediterranean and pre-desert scrub communities (5330) are particularly well-developed in the area, these being often characterised by dense populations of Euphorbia dendroides. The community within this site represents one of the best examples throughout the Maltese Islands and is deemed to be at a highly favourable conservation status, conferring a high ecological value and uniqueness to this habitat type in the area. This habitat type occurs on the extensive karstic plateau at Il-Qortin il-Kbir, at the headwaters of Wied Sabbara and at Il-Blat ta' Psaila. On the western valley-sides of Wied Sabbara, this habitat type occurs in conjunction with Hypericum aegypticum; such assemblage is usually referred to as phrygana (5430), but requires further studies as to its distinction from pre-desert scrub and other similar habitat types (such as from 5410).The temporary rainwater rock pools (3140 & 3170) occur scattered all over the area, depending on karstic depressions and rainfall. Examples of such communities are found in the areas of Ta' l-Ghadira, Il-Qortin il-Kbir and Il-Qortin iz-Zghir, and include an array of threatened vascular flora, including chandelier algae/stoneworts (Charophyta species), Elatine gussonei (Annex II Habitats Directive), Damasonium bourgaei, Ranunculus saniculaefolius, and Zannichellia melitensis, fairy shrimps (Branchipus sp./spp.) as well as the amphibian Discoglossus pictus (Annex IV Habitats Directive).Vegetated sea cliffs of the Mediterranean coasts with endemic Limonium spp. (1240) and calcareous rocky slopes with chasmophytic vegetation (8210), are both associated with coastal limestone cliffs, and occur as a mosaic of natural habitats throughout the belt of coastal cliffs extending from Ta' Cenc to Il-Bajja ta' Mgarr ix-Xini. The cliffs at Ta' Cenc support a very important rupestral maritime community with a variety of species that are otherwise rare across the Maltese Islands. Such species include Cremnophyton lanfrancoi, Palaeocyanus crassifolius, Matthiola incana ssp. melitensis and Hyoseris frutescens, all threatened Maltese endemic cliff species. The assemblage is also based on other endemics and species with a restricted distribution in the Mediterranean, including Limonium melitense, Darniella melitensis, Hypericum aegypticum, Crucianella rupestris, Daucus rupestris and Senecio leucanthemifolius. In addition, Coronilla valentina s.l. and Echium sabulicola, two species rare on the national scale, also grow at Ta' Cenc and Ras in-Newwiela respectively. In this respect, it should be noted that the cliff of Ta' Cenc support the best known population of the Annex II (Habitats Directive) species Palaeocyanus crassifolius in the island of Gozo (this species is rare on the island of Gozo).Footpaths in the area in general house an interesting assemblage of plant species, particularly within the area of Wied Sabbara, where Evax pygmaea, Romulea spp., Gynandriris sisyrinchium, Plantago coronopus s.l., Euphorbia exigua s.l. and Filago cossyrensis occur.Note on Section: Ecological Information - Habitats There are extensive areas in the Ta' Cenc area where habitat types co-occur. For instance, the priority habitat type Mediterranean Temporary Ponds (3170) and the habitat type Hard Oligo-Mesotrophic Waters with Benthic Vegetation of Chara spp. (3140) often co-occur in this site. In addition, they also co-occur with other habitat types, namely Thermo-Mediterranean and Pre-desert Scrub (5330), Pseudo-steppe with grasses and annuals of the Thero-Brachypodietea (6220), Vegetated Sea Cliffs of the Mediterranean Coasts with Endemic Limonium spp. Meadows (1240) and Calcareous Rocky Slopes with Chasmophytic Vegetation (8210). Percentage cover for these co-occurrences has been included under habitat type 3140. Furthermore, the latter two habitat types (1240 & 8210) also co-occur and percentage cover was included only once under habitat type 1240. The habitat type Thermo-Mediterranean and pre-desert scrub (Code 5330) also co-occurs with the two above-mentioned habitat types (1240 and 8210). In this case, the percentage cover of this co-occurrence was included in the percentage cover of habitat type 5330, since the latter appears to be dominant. Additionally, habitat type 5330 also co-occurs with habitat type Endemic Phryganas of the Euphorbio-Verascion (5430). The percentage cover of this co-occurrence was included under habitat type 5430.
