The relevés were subdivided into two groups, according to the two kinds of substratum (Eocene marls and Upper Cretaceous clays), and then submitted to Correspondence Analysis. According to these analyses and to abiotic parameters, nine vegetation types can be distinguished. Each community is characterized by ecological groups of species and by different life-forms spectra. The comparison among such communities, as well as with those of the non-eroded areas, allows to discuss their dynamic relationships in relation with erosion processes. As a generai rule, erosive dynamics involves a regressive succesion from the previous community (normally a mesoxerophilous pasture) through the opening of gaps and the loss of mainly mesophilous species. Thus, the badland communities on each substratum are dynamically connected, most stands having medium- to very low coverages and diversity, the topographic position and the related erosive processes being the most influential factors on their distribution.
