Vegetation of the natural monument “Urochishche Kuzilinka” and its surroundings (Orel region)

Abstract

The article describes the calciphytic steppe communities located in the territory of the natural monument “Urochische Kuzilinka” and its surroundings (Orel region). The communities were assigned to the association Onosmato simplicissimae–Salvietum nutantis Averinova ass. nov. That unit was included in the sub-union Bupleuro falcati–Gypsophilenion altissimae Averinova 2005 (union Festucion valesiacae Klika 1931, order Festucetalia valesiacae Soó 1947, class Festuco–Brometea Br.-Bl. et Tx. ex Soó 1947) on the basis of a diagnostic species analysis. The new association was characterized. Results of the ordination analysis of leading environmental factors for the described communities are provided.
