che06 | This syntaxonomic concept is recognised as a class in its own right by several Western European surveys (Rivas-Martínez et al. 2002; de Foucault 2009a). It is a unit of transitional character, mediating between the therophytic grasslands of the winter-mild regions (the Mediterranean and its fringes) and open forests of those regions. Indeed, most of the species co-occurring in these communities come from these two species pools and only very few actually characterise this syntaxon exclusively. It may well be that these communities might have been one of natural sources of the species-rich annual (sub) mediterranean flora occupying ruderal and otherwise disturbed habitats today. (L. Mucina).
