Lago di Capacciotti”
Habitat 1150* - Coastal lagoons:
Coastal lagoons are shallow coastal aquatic habitats with lentic, salt or brackish waters, characterized by considerable seasonal variations in salinity and depth in relation to water supply (continental or marine waters), rainfall and temperature which affects evaporation. They are directly or indirectly in contact with the sea, from which they are typically separated by sand or clays bars and less frequently by low rocky coasts. Sometimes this habitat is also present in the inner lagoon, in astatic endorheic basins.
In relation to a series of ecological factors such as salinity and water depth, seasonal variations of salinity and depth, type of substrate and temperature, coastal lagoons are characterized by diverse plant communities characterised by various phytocenoses. The phytocenoses similar to those found in the area of intervention are those highlighted below:
Ruppietum spiralis Hocquette 1927 corr. Inversen 1936 is found in shallow coastal lagoons, and is sometimes dried up during the summer, with loamy soils and salt waters with strong
variations in salinity;
Zosteretum Marinae Harmsen, 1936, is found in coastal lagoons and salt water sea-beds that move slowly over substrates with
fine sand mixed with low oxidized mud in areas affected
by fresh water flows.
The percentage of this habitat in the project SCI is not reported in the official form. This is due to the environmental changes over the last century that have caused its disappearance or alteration. Currently there are existing pieces of this habitat which represent what is left of the larger extensions that were present in the past near the mouth of the River Ofanto and where recovery
The aquatic vegetation of coastal lagoons is closely linked with the vegetation of the banks typically represented by Thero-Suadetea annual halophyte vegetation (Habitat 1310 "Annual pioneer vegetation Salicornia and other species of mud and sand"), by the perennial halophyte Sarcocornietea fruticosae related to habitat 1420 "Grasslands and Mediterranean and thermo-Atlantic scrub (Sarcocornetea fruticosi)", by helophytic vegetation of Phragmition and by rushes of Juncetalia Maritime from the habitat 1410 "Mediterranean salt meadows (Juncetalia maritimi)”.
They can be without vegetation or with rather differentiated vegetation types from the following classes Ruppietea maritimae J.Tx.1960, Potametea pectinati R.Tx. & Preising1942, Zosteretea marinae Pignatti 1953.

Habitat 2250* - Coastal dunes with Juniperus spp.:
The habitat is heterogeneous in terms of vegetation composition as it includes several types of woody vegetation dominated by junipers and other Mediterranean sclerophyllous plants.
Its vulnerability is generally due to tourism which causes alterations in the micro morphology of dunes, to urbanisation and to anthropogenic alteration of sandy coasts.
The habitat is distributed along the Mediterranean sandy shores and in Italy is only present in the Mediterranean and temperate regions. In the former, formations of Juniperus macrocarpa prevail, sometimes with J. turbinate. In the temperate macrobioclimate zone, rare J.communis formations may be found.
In the Mediterranean bioclimatic zone, juniper thicket with Juniperus oxycedrus ssp. Macrocarpa are predominantly found, sometimes with Juniperus phoenicea ssp. turbinata.
When the two junipers coexist, the predominance or exclusive presence of Juniperus oxycedrusì spp. Macrocarpa can be found on the seaward slope of the dune, whilst the other tends to prevail on the mainland side.
In the site of intervention, this priority habitat disappeared due to the environmental changes that have occurred over the last century. As it is one of the few sites that is suitable for restoration due to size and location (the coastal strip adjacent to the mouth of the river Ofanto), it will be subject to habitat restoration actions on over 3 km.
