Monitoring the state and ecological ameliorative effect of tree and shrub coulisse and row plantings on pastures in the arid conditions of the northern Caspian

Abstract

The paper summarizes results of long-term observations of the state of roadside tree and shrub plantings of Ulmus parvifolia, Tamarix ramosissima, Calligonum aphyllum and Haloxylon aphyllum in the arid conditions of the Northern Caspian. All said species show high survival on sandy loam soils, are drought-resistant and long-living (40 and more years). Studies have shown ecological and ameliorative effect of plantings on the vegetation cover of adjacent pastures and protection of the route Astrakhan-Volgograd from sand drifts and snowstorms of East and South-East directions.
