15.12 - Mediterranean halo-nitrophilous pioneer communities

Classification des habitats du Paléarctique (2001)

Description

Formations of halonitrophilous annuals (Frankenia pulverulenta, Suaeda splendens, Salsola soda, Cressa cretica, Parapholis incurva, Parapholis strigosa, Hordeum marinum, Sphenopus divaricatus, Polypogon maritimus, Spergularia spp., Vella annua) colonizing salt muds of Mediterranean and thermo-Atlantic coastal regions, of Iberian and North African endoreic basins, susceptible to temporary inundation and extreme drying; they are more species-rich or richer in non-chenopodids than the communities of unit 15.113; they are particularly developed in the Iberian peninsula, secondarily in the large Mediterranean islands, in coastal regions and endoreic basins of North Africa, in southern Italy and Mediterranean France; they occur as irradiations on thermo-Atlantic coasts, notably on the Atlantic coast of France. Somewhat similar communities occur in the steppe zones of Eurasia and their regions of influence, as well as in Saharo-Mediterranean steppes of North Africa; they are included in units 15.14 and 15.15.
