In his paper about the secondary, acidic low heaths and oligotrophic swards at low elevation, PREISING (1949) proposed to group these two formations, for Central Europe under an Atlantic climatic influence, in a single class--the 'Nardo-Callunetea' on the basis of their strong floristic affinities resulting from a common syngenesis. Syntaxonomically, each formation corresponds to an order--the 'Calluno-Ulicetalia' for the heaths, and the 'Nardetalia' for the swards.
