Uppsala school of phytosociology A set of floristic methods intended mainly for the classification of vegetation communities, developed by G. E.Du Rietz and others in Uppsala, Sweden, starting in 1921, at first quite independently of the work of the Zurich–Montpellier (Z–M) team. More recently the approaches have converged as many ideas have been modified in the light of Z–M work in an attempt to link the two. The main distinction between them lies in the emphasis placed by the Uppsala scheme on exclusive or preferential species of high constancy or dominance, rather than fidelity, to define the basic community types.
