In southeastern France Trochoidea geyeri is mainly an upland open-ground species, which has a very discontinuous range. An altitudinal shift of T. geyeri in response to Quaternary climatic changes is described. The value of T. geyeri as a palaeoclimatic indicator species is discussed. Its distribution seems to be partly conditioned by competition with Candidula unifasciata (Poiret).
