The presence of ground vegetation as indicators of site conditions was researches in three beech stands in the area of Severni Kucaj in East Serbia. The plants of the ground flora were registered by Braun-Blanquet method: the species which indicate soil acidity, humus type, and the species which disturb the natural regeneration of these forests. In the stand 33a, with the prevailing limestones, the most represented species are neutrophilous species. Acidophilous and basiphilous species are present only in individual releves, and they occur exclusively as individuals. Of the humus indicators, the species which indicate mull humus have the highest percentage, which points to the favourable conditions of the organic matter transformation and the fast nutrient cycling in the ecosystem. The species which disturb natural regeneration are the Rubus species. In the stands 42a and 42b, due to an excessive weediness by Rubus species, the other ground flora is scarce. Still, the neutrophilous conditions of soil acidity, as well as the fast organic matter transformation, were assessed based on the present plants.
