The present research discuss the total intensity of the biological turnover in the beech communities in the Western Balkan mountain, as well as a kind and the quantity of the litter – fall. Three communities were investigated. The samples of a litter-fall and mulch were collected from them. The quantity of the litter-fall varied from 3,2 to 4,2 t.ha-1. The litter-fall was fractionated on leaves, branches, cupolas and other liter-fall. The fraction of the leaves was prevailing. The total intensity of the biological turnover was calculated through the litter-mulch coefficient according Bazilevich and Rodin method (1). It was varied from 1,3 to 2,1 for the investigated communities according 10 bal scale. The intensity of the turnover was from intensive to inhibited. The inhibited turnover is characteristic for the broad-leaved forest communities. The presence of the communities with intensive turnover is indicator for disturbances of the functioning of the particular community. In a concrete example the investigated ccommunities was in the immediate vicinity to highway and it was very probably that the pollution was the cause for the changes in the decomposition. |
