Other Site Characteristics

The most important community at this site is the Maltese National Tree Tetraclinis articulata maquis. The highest individuals have a height of approximately 6m and are growing at altitudes of up to 140m. Most are found growing in fissures of rocky slopes in the area.Apart from the Tetraclinis maquis, other maquis communities exist in the area, dominated by Carob, with Pistacia lentiscus, Prunus dulcis, Rhamnus oleoides, Ficus carica and Olea europaea.

4.2 Quality and importance

A part of this site constitutes a Tetraclinis articulata community. It is Malta's largest known population of Tetraclinis articulata, Malta's National Tree, a locally endangered tree that has a restricted distribution in the Maltese Islands. It is considered to be an important community in the Maltese archipelago, especially as very few such trees still survive in the wild and are only found on mainland Malta; also, its geographical range is very restricted across Europe as it is only found in Malta and in a locality in the area of Cartagena (S.Spain) (but it is also present in N.W. Africa).Tetraclinis maquis is often referred to as a dominant vegetational assemblage in the past, possibly suggesting that the Wied il-Mizieb Tetraclinis maquis is the last remnant of an assemblage that previously covered much larger areas of the islands and that were then replaced by a different form of maquis dominated by other species, possibly as a result of cultivation of olive (Olea europaea).It is significant to note that a considerable number of plant communities can be found growing in the area. The Phrygana habitat present in the area consists mainly of Anthyllis hermanniae, while the Pre-desert Scrub habitat is based on Periploca angustifolia and Euphorbia melitensis. Various plants occur within these communities, including: Carlina involucrata, Erica multiflora, Euphorbia melitensis, Rhamnus oleoides, Periploca angustifolia, Asparagus aphyllus, Ceratonia siliqua, Chiliadenus bocconei, Ficus carica, Opuntia ficus-indica (well-established alien), Pistacia lentiscus, Senecio bicolor, Teucrium fruticans and Thymus capitatus, with Andropogon distachyus, Brachypodium retusum, Piptatherum caerulescens (endangered; restricted distribution across the Maltese Islands), and Hypparhenia hirta amongst the grasses and Asphodelus aestivus and Urginea pancration amongst the geophytes. Fauna associated with Tetraclinis include insects, crustacea, arachnids, molluscs, gastropods, and vertebrates (although further studies are required). These include the endemic and endangered beetle Torneuma strictum, for which this site represents the type locality; it is found in soil at 10-30cm depth under Tetraclinis articulata. Another vulnerable endemic with a restricted distribution in the Maltese Islands, namely Microptinus melitensis, is known from leaf litter under Tetraclinis articulata. Also known from the area is the frequent endemic homopteran Aleurolobus teucrii, a species monophagous on Teucrium fruticans. Maniola jurtina hyperhispulla and Papilio machaon melitensis, both reported as endemic lepidoptera, are also known from the area. Other species include the endemic snail Trochoidea spratti, and Hemidactylus turcicus, Chamaeleo chamaeleon, Elaphe situla and Podarcis filfolensis maltensis amongst the herpetofauna of Wied il-Mizieb.The bat species Myotis blythii punicus is reported from the area. It is a vulnerable species in the Maltese Islands, and is nationally and internationally protected. Another bat species that is nationally protected and which has been recorded from this site is Pipistrellus pygmaeus, which is also a vulnerable species in the Maltese Islands.Note on Section: Ecological Information - Habitats In view of the habitat type 9320 Olea and Ceratonia forests, these refer to individual trees often located at the margins of fields. These have been grouped together for the purposes of habitat type mapping.
