COMPOSITION AND BIOMASS OF HERBACEOUS LAYER IN STAND DAMAGED BY FELLING TILIA CORDATA MILL
The effect of continuous stripped-coupe cutting in plantations Tilia cordata Mill the species composition and biomass of living ground cover. Revealed that of undisturbed the grasses cover cuttings lime-tree represented by 20 species of plants and consists of five of substages. Species richness confined to 17 families. Found that the third growing season after logging out of living ground cover falls most typical for a dense tree canopy lime-tree species — Ground-pine, European Asarum, Stellaria Sclerophyllous, Grass Spring, Ivy Boudreau, etc., increases availability of species of Poaceae Barnhart. Comparative evaluation of the floristic composition of herbaceous plants in linden, intact deckhouse and in stands, formed after solid strippedcoupe logging in summer and winter seasons, indicates a sufficiently high degree of similarity of herbaceous vegetation study sites and restores living ground cover in a derived forest stand over a 20 year during after felling. Average value of species similarity Jaccard to control (prior to cutting) and a plot of winter cutting were 0.71; section for the summer season cutting and control — 0.75; sections for summer and winter seasons cuttings — 0.68. In plantations, formed by after felling, were identified from 17 to 19 kinds of herbs (14–16 families). Besides changing species of plants, loss of individual species, changes in their abundance and occurrence in grass cover decreases vegetation biomass in a completely dry state with 10.04 g/m2 to 6.5 g/m2 control at the site of the summer season cutting.
