Ecological Characteristic of Feather Grass Habitat (Stipa pennata L.) in Various Parts of the Range

The article gives an analysis of the ecological diversity of Stipa pennata cenopopulations in different parts of the range using D. N. Tsiganov’s amplitude ecological scales (1983) for 10 environmental parameters. Communities with S. pennata in the center of the range in the northeast of the Saratov right bank in the "Khvalynsky" National Park and at the northern border of the range in the eastern part of the Russian plain in the «Mari Chodra» National Park are considered.
