ABSTRACT. Pioneer ant communities formed at the ash dump of Novosibirsk CHPP-5 (55°002 N, 83°042 E) by the 9th year of self-revegetation period were explored. Investigations were carried out during July-September 2017 at non-reclaimed section of the ash dump divided into three zones according to the humidity of ground and corresponding plant association. The collection of the material was carried out on model sites (10x10 m, 5 in each zone). 10 ant species were revealed at the ash dump (Camponotus japonicus, Formica rufibarbis, F. cunicularia, F. fusca, Lasius niger, Myrmica cf. constricta, M. curvithorax, M. scabrinodis, M. schencki and Tetramorium caespitum). C. japonicus was recorded for the first time in the Novosibirsk Region. Nests of Formica ants were not found at the ash dump. Solitary foragers of the genus Formica subgenus Serviformica were just beginning to explore the technogenic landscape, penetrating to the periphery of the ash dump from the adjacent undisturbed territory. As the degree of soil moistening increases, the number of ants, living on the ash dump, increases from 1 to 6 species. L. niger dominates in ant communities. In the humid zone of the ash dump Myrmica cf. constricta also joins the number of dominants.
