The purpose of the work is to establish the ecological situation in the pasture phytocomplexes of the Don basin. The objects of research were plant communities on floodplain sod-meadow granular soils and on the sands of the Ilovlinsky massif of the Volgograd region. The occurrence of species on the Drude scale, the vital state of plants, the projective cover of vegetation, and the feed mass consumed were determined. It is established that the main mass of vegetation is oppressed or is in a satisfactory condition. The dominant phytocomplexes are representatives of the Asteraceae families that are resistant to anthropogenic loads and lodging, with a wide ecological amplitude (30% on floodplain sod-meadow granular soils, 38% on sands) and Poaceae (13% on floodplain sod-meadow granular soils, 29% on sands). On floodplain sod-meadow granular soils with a projective vegetation cover of 45%, the feed mass of autumn pastures was 51.2 g/m2, on sands with an average projective vegetation cover of 21%, the feed mass was 24.4 g/m2.
