Successional changes of Nardus stricta communities in the Central Balkan Range (Bulgaria)

Abstract

Abstract. Main succession changes are traced down in the Nardus stricta communities from the Central Balkan Range (Bulgaria). The demutational phase covers a period of 2–3 decades. Vegetation dynamics processes are analysed in parallel, according to the method of Braun-Blanquet and the Dominant approach. Classification of the communities according to the two approaches is offered. The Nardetum strictaе and Bruckenthalio-Juniperetum sibiricae associations represent two opposite points in the succession process. The spatial and the syntaxonomic correlation between the vegetation units is analysed, regarding the two phytocoenological schools.
