Analysis of the Vegetation Covering Under the Influence of the Different Abundance of Juniperus sibirica in Two Zones of the Central Balkan Mountain

Abstract: The composition of the vegetative communities over two zones of the alpine woodless part of the Central Balkan Mountain has been examined. The description 2 of the varieties has been realized in experimental areas with size 16 m , chosen according to the different abundance of Juniperus sibirica Burgsd. – from 0 to 100%. The analysis carried out showed that the number of registered varieties over terrains abundant in juniper from 0 to 40% is almost the same. In the case of abundance of J. sibirica over 50%, and especially over 75%, the varieties composition in the communities decreases almost by half. The high inclination and breaking of the terrains from the one part, and the soil-protective and strengthening role of the juniper bushes from the other part, determines the necessity to limit the invasion over J. sibirica up to 40-50%, and not to her complete elimination.

Key words: Juniperus sibirica Burgsd., phytogeography, ecology, communitiеs.
