Geographical distribution, seed productivity and protection of Stipa L. genera in the steppes of Right-Bank Dnipro area

The data about distribution of Stipa L. species on the Right-Bank Dnipro area are cited. It is underlined that the existent network of the nature reserve fund of this region does not provide the effective protection of survived steppe grasses. The necessity of Stipa L. species conservation in botanical gardens is proved. Five species of Stipa L. genus were studied and introduced in the Kryviy Rig Botanical Garden. The results of these species introduction are adduced
