Other Site Characteristics

This site is relatively large when considering Malta. Justification for this isbased on the SLOSS (Single Large Or Several Small sites) debate on site design. Contrary to several small sites, a single large site has low edge effect, affords better protection to organisms with large area requirements and is easier to manage. Moreover this approach is also in line with the suggested ecological coherence (Article 3 & 10) necessary for better conserving Natura 2000 sites.The seabed geomorphology in the site is considerably heterogeneous giving rise to a number of varied seascapes, bottom types and a number of different habitat types.

4.2 Quality and importance

This area hosts the largest variety of Posidonia sub-types when considering themarine sites selected to form part of the Natura 2000 Network, with therepresentativity of each being considered superior. The subtypes present in thissite are the following: - Posidonia settled on matte, whose meadows are normally continuous and having a high density; - Posidonia settled on rock, showing a reticulate distribution of dense strands; - Posidonia settled on sand, with continuous beds generally showing lowdensities and variable percentage cover; - Mosaic morphology, intermixed between Posidonia oceanica, Cymodocea nodosa and coarse sand, showing a reticulate structure; - Ecomorphosis of 'barrier reef' Posidonia meadows.The Posidonia meadows within this site are also known for a high degree ofconnectivity, as well as percentage coverage.From the data available through a Posidonia Baseline Survey carried out in 2002,it is evident that the Posidonia meadows in various parts of this site are veryabundant and healthy. They are dense and show a high degree of shoot density,particularly in White Tower Bay, which appears to host probably the highest shootdensity in the Mediterranean. The site is also known for the deepest recordswhere Posidonia grows, namely off the south coast of Comino. However, in someareas within this site, such as at Mistra Bay and at Mellieha Bay, the beds areshowing signs of regression, especially as a result of anthropogenic activities.Sandbanks, formed by associations of Cymodocea nodosa are also present within this site. The following subtypes are present: - sandbanks with associations of Cymodocea nodosa on well-sorted fine sands; - sandbanks with associations of Cymodocea nodosa on superfically muddy sands in sheltered waters; - facies with Cymodocea nodosa occurring within coarse sands and gravels with more or less mud.As part of a survey carried out in 2002, reefs have been identified within this site, occurring on hard beds and rocks. The following subtypes occur within this site: - reefs with associations of Dictyopteris polypodioides; - reefs with associations of Halopteris scoparis and Padina pavonica; - reefs with associations of Flabellia petiolata and Peyssonnellia squamaria; - reefs with associations of Cystoseira spp.Partially submerged caves are also present, mostly located along the coast of Comino. No quantitative data is available for this habitat type.Amongst the important species within this site is Lithothamnion minervae, aspecies which has been included in national legislation as a plant species ofnational interest whose conservation requires the designation of Special Areas ofConservation.Gibbula nivosa, which is considered as the only endemic marine mollusc of Malta, and is listed as having a vulnerable status and a restricted distribution within Maltese waters, is also present within this site. Gibbula nivosa has been found on Posidonia oceanica leaves and under stones.Note on section: Ecological Information - Habitats The extent of national territory covered by Annex I marine habitat types 1110 & 1170 is not known; hence the relative surface fields were left blank. Caves (8330) are present on site, but have not been mapped; hence fields in Section 3.1 were left blank.
