Subnitrophilous annual grassland

English name: Subnitrophilous annual grassland

Description (English)

Land dominated by annual grasses and herbs, on soils slightly enriched in nitrates, in the meso- and thermo-Mediterranean zones. Characteristic are Bromus, Aegilops, Avena, Vulpia, crucifers and leguminous plants. These annuals occur as pioneers of bare soils slightly nitrified by aeration or organic addition, along roads, on land-fills and in interstitial spaces of cultivation. They also replace the oligotrophic annual vegetation of Mediterranean xeric grasslands (E1.3) under the influence of pastoral activities. Subnitrophilous annual grassland is widespread as a successional stage after cultivation. Woody recolonisation may lead to maquis (F5) or garrigues (F6).
