The associations formed by Alnus incana (L.) Moench. in the south of Western Siberia are limited to the middle and lower reaches of the Irtysh river in the Tyumen region (Tobolsk district, Russia). The paper describes Alnetum pteridiosum, Alnetum urticosum, Alnetum еquisetosum, Alnetum coricosum, Alnetum coricoso – еquisetosum, Alnetum coricoso – oxalidosum, Alnetum curtico – еquisetosum, Alnetum еquisetoso – miliosum, Alnetum coricosa – stellariosum, Alnetum urtico – aegopodiosum, Alnetum urtico – stellariosum, Alnetum–cirsiosum, Alnetum cystopteriosum, Alnetum urtico – miliosum, Alnetum poо – urticosum, Alnetum chrysospleniosum, Alnetum corydaliosum, Alnetum impatieno - urticosum and Alnetum stellariosum associations. In these associations, more than a hundred of species of higher plants grow. The species composition analysis showed that they are mesothermal and hydrophilic, the shrub layer is not typical for them, and the grass cover of alder forests is not uniform in origin. During the formation of Alnetum association they interact with taiga, birch and linden forests through mutual exchange of species, and also experience anthropogenic influences, accompanied by the penetration of synanthropic species.
