Thermo-Mediterranean and pre-desert scrub

Liste hiérarchisée et descriptifs des habitats d'intérêt communautaire de la directive "Habitats"


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 phryganas, which, however, on account of their strong structural singularity, are listed separately under 33.
Sub-types :
32.21G - Genista fasselata brush
Brushes dominated by the tall, spiny Genista fasselata of very restricted distribution in the eastern Mediterranean basin.
31.8B5p - Xerophilous Crataegus azarolus var. aronia scrub.
Low to medium height scrub of the semi-arid zone of Cyprus characterised by Crataegus azarolus var. aronia with an abundance of herbs and grasses and belonging to the Genisto-Ceratonietum. It develops at low to medium altitudes (300-500 m) on calcareous substrates.
32.22 - Tree-spurge formations
Stands of Euphorbia dendroides, remarkable tertiary relict of Macaronesian origin; they occur as a facies of the thermo-Mediterranean brushes of the Balearics, Corsica, Sardinia, Sicily, Isles Eolie, Egadi, Pelagi, Pantelleria, Crete, and, very locally, of those of the coasts of northern Catalonia, south-eastern France, peninsular Italy and its islands, central Greece, notably on slopes facing the gulf of Corinth, the Peloponnese, the Aegean archipelagos, and enclaves of the Mediterranean periphery of Anatolia and the Levant. Particularly extensive and robust stands occur in Sicily, Sardinia and Crete where they may extend to relatively high altitudes. Very local formations in Mediterranean North Africa occupy the steep rocky slopes of some coastal capes and isolated inland sites (Ichkeul).
32.23 - Diss-dominated garrigues
Garrigues invaded and dominated by the high tussocks of Ampelodesmos mauritanica; typically thermo-Mediterranean, they also occur extensively in the meso-Mediterranean zone. They are
most prevalent on the Tyrrhenian coast of central and southern Italy, in Sicily, in the Mediterranean zone and the less arid parts of the Saharo-Mediterranean transition zone of North Africa.
32.24 - Palmetto brush
Chamaerops humilis-dominated formations; other thermo-Mediterranean brushes or garrigues rich in the physiognomically important palmetto can be identified by a combination of this code
and that of the other appropriate subdivision of 32.2. Palmetto brushes are best represented in the coastal areas of south-western, southern and eastern Iberia, the Balearics, Sicily and its
satellite islands and Mediterranean North Africa, with more sporadic occurrences in the Guadalquivir basin, Sardinia, and the Tyrrhenian coasts and islands of peninsular Italy.
32.25 - Mediterranean pre-desert scrub. Periplocion angustifoliae, Anthyllidetalia terniflorae.
Shrub formations constituting, with the halo-nitrophilous scrubs (15.724) and the localised gypsum scrubs (15.93), much of the natural and semi-natural vegetation of the arid zone of south-eastern Spain (Almeria, Murcia, Alicante), a highly distinctive region of unique climatological, biological and landscape character within Europe, extremely rich in African and endemic species. Several of the most remarkable formations remain in only a few undisturbed localities and are gravely at risk18. Similar formations occur in the upper arid (Mediterranean arid) zone of North Africa. Outposts of these communities also exist in Sicily, the Egadi islands, the Pelagie islands, Malta and Pantelleria

Description (suite)

32.26 - Thermo-Mediterranean broom fields (retamares)
West Mediterranean formations dominated by retamas (Lygos spp.) or by large, non-spiny thermo-Mediterranean brooms of genera Cytisus and Genista, limited to the Iberian peninsula, the Balearics, Mediterranean North Africa, Sicily and its associated islands, the Cilento coast of Campania.
32.441p - Spiny spurge garrigues
Euphorbia melitensis garrigues of Malta
