Korovyakova T. Reaction of meadow forbs populations on mowing and a pasture in the conditions of flood plain meadows of the river Psel (Sumy Region)

The thesis presents the results of the population analysis of meadow forbs of the Psel flood plains under different modes of pasturable and haying loads. Study area is Sumy Region ( Forest-Steppe zone of Ukraine). On the meadows of the class Molinio-Arrhenetheretea control parcels of land have been allocated and pasturable digression gradient has been subdivided into 5 steps, while fenisical digression into 4. In the meadow phytocoenothes of the flood plains of the Psel forbs is considered to be the most numerous group (68%) representing by 251species from 155 genera, 45 families. The pasturable-haying control system of meadows and the improvement of natural fodder grounds of the Psel flood plain are proposed.
