MAL022 - Ghadajjar ta' l-ilma helu fil-Qaliet (l/ta' San Gi

This site is located on the coast and supports a saltmarsh. The transitional wetland dominated by Juncus acutus is designated as a Level 1 Area of Ecological Importance (AEI) and a Level 1 Site of Scientific Importance (SSI), a buffer area is included which is scheduled as a Level 3 AEI. Part of the area scheduled as a Level 3 AEI has since been developed. The coastline is part of the locality of St Julian’s, a highly touristic area. The site is easily accessible to members of the public through an entrance at Triq il-Wilga, as there are no gates or barriers limiting access to the site. It is also accessible from a footpath along the Portomaso breakwater, however, few people use this route to reach the site. The coastline is particularly popular as a daytime bathing destination in summer, and the coast is also popular with anglers. It is also frequented in the evenings, especially during the weekend. The saltmarsh habitat type occupies natural depressions a few metres inland from the coastal edge. The habitat is dominated by rushes belonging to the species Juncus acutus (Sharp-pointed Rush) which constitutes over 90% of the vegetation cover. The remainder is made up of Limbarda crithmoides (Golden Samphire) and a combination of various ruderals and coastal species including Euphorbia pinea (Pine spurge), Cichorium spinosum (Spiny Chicory), Dittrichia viscosa (Sticky Fleabane), Daucus carota (Wild Carrot), Capparis orientalis (Caper Plant), Mesembryanthemum nodiflorum (Lesser Crystal Ice Plant), Lagurus ovatus (Hare’s Tail Grass) and Plantago lagopus (Mediterranean Plantain). This habitat type is classified as Natura 2000 Annex I habitat 1410, or the Mediterranean salt meadows (Juncetalia maritimi), for which reason the site was originally scheduled in 1995. The rush community is relatively dense with a total vegetation cover of over 80% and an average height of around 1m. Ruderal species recorded are largely found at the edge of the habitat, and their presence is a result of the disturbance generated on site from trampling and a high footfall of visitors. Litter and a large quantity of broken glass were also observed throughout the saltmarsh. Despite the disturbance and abundance of litter, the saltmarsh is well structured, constituting one of the best conserved coastal marshes in the country. The core of the habitat is almost entirely composed of characteristic species, with ruderals being restricted to the edge of the habitat and to the footpath crossing through the habitat. The conservation of habitat function was relatively stable, and the structure of the habitat is unlikely to deteriorate in the short term, despite the large number of visitors. This is most likely because bathers avoid the marsh in view of the spiny nature of the dominant species.The saltmarsh habitat is absent from higher ground that rises above 0.5 m and is instead replaced by a coastal garrigue dominated by Limbarda crithmoides.
