Processes of plant regeneration and restoration of destroyed ecosystems, naturally occurring, in such areas are very slow. Considering sand pits as a man-made form of relief necessitates a comprehensive study of the features of sand pits vegetation, which helps stop the movement of sandy slopes, stabilize sands, and land reclamation. We have studied the slopes of the northern and southern exposition in some sand quarries (Zvenigorodsky, Dzerzhinsky, Ramensky (GOK), Lytkarinsky, Lyzlovo). Geobotanical descriptions, performed according to a standard method on the experimental areas of 5×5 square meters, are the basis of our work. The article shows that all the 93 species which we have found in the surveyed area were species of vascular plants. In this case the number of species is not only determined by the smooth running development of the landscape (taking into account the fact that the interference was rude and had a man-made factors), but by other factors such as steep slopes, light, moisture, and richness of the soil. The projective cover of sand pits constitutes 20-30 % which, in general, is a typical characteristic of sandy terrain [3]. Plants overwhelming majority in the spectrum of life forms according to K. Raunkiaer, are Hemicryptophytes, which is typical for the phytocoenosis of the Central Russia. It can be noted that the Chamaephytes are absent in most quarries, except for Dzerzhinsky. According to the classification of life forms by I.G. Serebryakov, sand slopes are dominated by herbaceous perennial polycarpics, among which long and short rhizome plants and tap rooted plants are in majority. Meadow plants are dominant in ecological-coenotic group. This group consists of fully developed plants, only, under conditions of good lighting. The rate of adventive species is low.
