Other Site Characteristics

This site consists of a deep, large-scale inland collapsed solution structure. It is the best example within the Maltese Islands and it is probably a doline. It was caused by dissolution of limestone followed by cavern collapse. This may take place again due to the sink-hole present underneath. The geological structure of this site is of particular interest as in Malta it is the largest conspicuous doline completely isolated from the sea. (There are other large dolines isolated from the sea, but these are not as conspicuous as Il-Maqluba as they are filled with sediment). Thus, it potentially provides a habitat that is unique within the Maltese Islands. The doline is sufficiently large such that it is suitable for agriculture due to the fact that there is shelter from wind, a high extent of humidity and the presence of soil cover. In fact, the doline bed has been cultivated in the past, and a fruit orchard was possibly present. The remnants of rubble walls in the doline bed indicate agricultural practices. Although such practices were abandoned, the doline now supports an important population of Laurus nobilis. Then, the sides of the cavity constitute a mixed rupestral and maquis vegetation. This includes Salsola melitensis (= Darniella melitensis), Tetraclinis articulata, Hedera helix, Capparis orientalis, Ficus carica and Opuntia ficus-indica. The doline bed has a greater species richness than the vertical walls.

4.2 Quality and importance

This Natura 2000 site is important as the doline bed supports a dense maquis which is dominated by Laurus nobilis, this being locally rare, with a restricted distribution throughout the Maltese Islands (National Red Data Book). The Bay Laurel tree is a characteristic Mediterranean tree and a true Maltese native, as is confirmed by fossil evidence. The Laurus nobilis community present at this site is relatively important. It is undisturbed, and it is the only site in Malta where they are found that is humid (they grow better in such conditions). Otherwise, such a community is extremely rare across the Maltese Islands due to a lack of humid areas. Also, only a few communities reach the height of the trees found at this site. The immediate area around the dense maquis that is dominated by Laurus nobilis (i.e. the collapsed area), also supports a maquis that is dominated by Ceratonia siliqua and Crataegus monogyna. Other maquis species present in the area include Pistacia lentiscus, Rhamnus oleoides, Punica granatum, Asparagus aphyllus, Lonicera implexa and Smilax aspera, as well as Arundo donax. Most of the trees in the area are legally protected. The undergrowth consists of Acanthus mollis, Smyrnium olusatrum and saplings of Laurus nobilis. Then, the most important sciaphilo-nitrophilus undergrowth vascular plant species is Arum italicum. Il-Maqluba itself, particularly the maquis and its trees, are important for macrofungi and myxomycetes, which include many species that are confined to this area or with a restricted distribution in the Maltese Islands. The wall and crevices in the rock house an interesting community of species requiring shady humid conditions. These include the ferns Adiantum capillus-veneris and Anogramma leptophylla, as well as the rare Mediterranean Pellitory Parietaria lusitanica (which is scarce in the area and is overall locally rare, occuring in small numbers in a few valleys of Malta and Gozo). Crevices in more 'exposed' parts include a small population of the very rare Tetraclinis articulata, a species known from Malta and Spain only in the Mediterranean. The few Tetraclinis articulata trees present are definitely not a forest, and hence, the community present at this site does not compare very well to the Tetraclinis articulata forest habitat described in the Interpretation Manual for the Habitats in the Habitats Directive. This Arbor-vitae or Xero-thermophile assemblage is only made up of about 4 or 5 specimens that occur on the upper vertical walls of the doline. In the more exposed crevices and fissures, Salsola melitensis (= Darniella melitensis), with Capparis orientalis, the alien Opuntia ficus-indica and Chiliadenus bocconei are present.Salsola melitensis (=Darniella melitensis) is endemic to the Maltese Islands and is the only European representative of the genus Darniella At Il-Maqluba, it is mainly found on the vertical doline walls, forming only a fringe of vegetation along the doline. Being an endemic species and the only species of Darniella across Europe, the community at this site is definitely unique and also far from the description given for this type of habitat in the Interpretation Manual. Chiliadenus bocconei is possibly the commonest of our endemic plants. Salsola melitensis (=Darniella melitensis) and Chiliadenus bocconei are both palaeoendemics of North African / Saharan affinities. On the other hand, Tetraclinis articulata is of Maghrebian affinity. Another interesting point is the fact that the rare Siculo-Maltese endemic Iris sicula is also reported from Il-Maqluba. This is considered to be locally vulnerable and it has a restricted distribution. Other plant communities present at the site include the following: Reedbeds: stands of Arundo donax (within the doline); Carob scrub: based upon Ceratonia siliqua (within the doline and also in the surrounding area); this is probably of secondary origin; Ruderal assemblage: large tract of 'disturbed ground' with weedy species (within the doline); Mediterranean subnitrophilous grass communities: based upon Stipa capensis and Avena spp. (in the area outside the doline); Ermes: this is based upon Urginea pancration and Ferula communis and Cultivated areas: a number of cultiavted fields, mainly bearing seasonal crops, occur around the upper rim of the doline structure. With respect to fauna, some interesting species occur. These include: Strumigenys lewisi: this ant is only found at Il-Maqluba when considering the Maltese Islands and it is considered to be a tramp species; Deroceras golcheri: this is an endemic slug (National RDB) and Il-Maqluba is a type locality for this mollusc; it was first described from Il-Maqluba but it is quite widespread throughout the Maltese Islands; it may also be possibly found on the Italian island of Montecristo; Bathytropa schembrii: this woodlouse is possibly endemic to Malta (not as yet found on any of the other Maltese Islands) and possibly it is also very rare (National RDB); it is only known from Attard, Buskett (type locality) and Il-Maqluba, it being common in these three localities; Leptothorax rabaudi and Paratrechina longicornis: rare ants and Lepismachilis sp.: a silverfish species. The doline bed is also particularly important for cryptofauna, particularly those that require deep layers of leaf litter in shady and humid conditions. Furthermore, a number of soil-inhabiting species have been found in soil at 10-30cm depth, often under trees, many of which have been recently described as new species to science, endemic to the Maltese Islands. These include the endogean beetles: Amaurops mifsudi: an endemic beetle known from Il-Buskett and Il-Maqluba (Poggi, 1999) and Torneuma maltense: an endemic beetle known from Il-Ballut l/o Wardija, Il-Buskett, Il-Maqluba, L-Imtaħleb, San Blas and Wied Babu (Magnano & Mifsud, 2001).
