Changes in the species composition of temporary grass and grass-clover crops stands were studied in 1994–2000. The assessment consisted in determination of the dominance of individual species, measurement of their aboveground biomass weight and subsequent comparison of detected values. The measurements were evaluated by the method of determination of distance between vectors of stand composition and by the subsequent standardization. Resulting values are in a good agreement with the hither to knowledge and confirm that more favourable yield parameters are achieved within 30–60% of total changeability. Changes of species composition and stand changeability are at their initial stages of succession given by external changes mainly contributed to by the group of clumpy grass species and by internal changes within the group of pod-bearing plants.Keywords:
