5330 Thermo-Mediterranean and pre-desert scrub: Scrub formations characteristic of the thermo-Mediterranean zone. Included here are those formations, for the most part indifferent to the siliceous or calcareous nature of the substrate, that reach their greatest extension or optimal development in the thermo-Mediterranean zone. Also included are the numerous, strongly characterised, thermophile formations endemic to the south of the Iberian Peninsula, mostly thermo-Mediterranean but sometimes meso-Mediterranean; in their great local diversity they are a western counterpart of, and sometimes approach in appearance, the mostly eastern Mediterranean garrigue, which, however, on account of their strong structural singularity, are listed separately under 33.
5410 West Mediterranean clifftop phryganas (Astragalo-Plantaginetum subulatae): Rare, extremely local and isolated, cushion-forming thermo-Mediterranean sclerophyllous associations of clifftops and adjacent areas dispersed along the coasts, characterised by the presence of Astragalus massiliensis or Anthyllis hermanniae, variously accompanied by Thymelaea hirsuta, Helichrysum italicum, Plantago subulatum, Armeria ruscinonensis.
9320 Olea and Ceratonia forests: Thermo-Mediterranean or thermo-Canarian woodland dominated by arborescent Olea europaea ssp. sylvestris, Ceratonia siliqua, Pistacia lentiscus, Myrtus communis. Most formations will be listed as arborescent matorral (35.12), but a few stands may have a sufficiently tall, closed canopy to qualify for this unit.
3170* Mediterranean temporary ponds: Very shallow temporary ponds (a few centimetres deep) which exist only in winter or late spring, with a flora mainly composed of Mediterranean therophytic and geophytic species belonging to the alliances Isoëtion, Nanocyperion flavescentis, Preslion cervinae, Agrostion salmanticae, Heleochloion and Lythrion tribracteati.
1150* Coastal lagoons: Lagoons are expanses of shallow coastal salt water, of varying salinity and water volume, wholly or partially separated from the sea by sand banks or shingle, or, less frequently, by rocks. Salinity may vary from brackish water to hypersalinity depending on rainfall, evaporation and through the addition of fresh seawater from storms, temporary flooding of the sea in winter or tidal exchange.
1310 Salicornia and other annuals colonizing mud and sand: Formations composed mostly or predominantly of annuals, in particular Chenopodiaceae of the genus Salicornia or grasses, colonising periodically inundated muds and sands of marine or interior salt marshes.
1410 Mediterranean salt meadows (Juncetalia maritimi): Various Mediterranean and western Pontic (Black Sea) communities of the Juncetalia maritimi.
1420 Mediterranean and thermo-Atlantic halophilous scrubs (Sarcocornetiea fruticosi): Perennial vegetation of marine saline muds (schorre) mainly composed of scrub, essentially with a Mediterranean-Atlantic distribution (Salicornia, Limonium vulgare, Suaeda and Atriplex communities) and belonging to the Sarcocornetea fruticosi class.
