Abstract

The comparative study of meadows on long fallow lands and natural meadows from the subtaiga subzone of the West Siberian plain was carried out using the species activity and occurrence indices. It was shown that floristic composition of grass communities depended on their previous agricultural usage. Groups of differentiative species for long fallow and natural meadows were determined. At the same time, a group of species showed similar occurrence and activity indices in all the variants of meadow communities. This fact proves the unity of meadow vegetation on the territory of the subtaiga subzone of the West Siberian plain.
