The state of some protected areas in the landslide slopes on the right bank of the Volga river

In this paper, we describe the state of some protected areas during stabilization of landslide processes. We discovered some rare plant species in the forested and stepped phytocenosis areas on landslide elements, and observed that the fraction of stepped plant species at the protected area «Mountain Lobach» has been partially recovered on the main slope and the edge after the grazing was ceased and make up 36% of the overall vegetation with a gradual decrease at landslide elements: meadow-steppe down to 5.8% and steppe-meadow down to 1.9%, some of rare plant species are marked - Stipa pennata, Pimpinella titanophila . At the same time, the fraction of wet meadow, wetland grasses, and ruderal species on the landslide mounds increased from 15% to 46%. During the 16-year period of observations, the increase in moisture and change in soil acidity are observed due to the slopes of the elements and the ongoing processes of sliding. We observed successions of plant community on the forested slopes due to a constant impact of the river that activates soil gravitational mobility, which in turn reduces the interspecies competition and causes insufficient soil cover development and low crown density and often promotes the growth of some rare forest and forest-meadow plant species - Gymnocarpium robertianum , Cypripedium calceolus , Epipactis atrorubens , Cephalanthera rubra , Gymnadenia conopsea , Orchis militaris, Astrer alpinus .
