In 1994 phytosociological experiments were carried out on green land in the Czerniejówka valley by means of the Braun-Blanquet method. As a result of yielding two crops of hay a year, sometimes also grazing of the second outgrowth, plant complexes belonging to the class Molinio-Arrhenatheretea, the order Arrhenatheretalia, were, among other ones, formed. The complexes Arrhenatherum medioeuropaeum, but without Arrhenatherum elatius, appeared the commonest ones as well as the community Poa pratensis-Festuca rubra. Their botanical composition and sizes of yields were different.
