In 1983-1985, the population of ground beetles (Coleoptera, Carabidae) of plain lignified brown coal dumps in the south of the Krasnoyarsk Krai (Kansk-Achinsk fuel and energy complex, KATEK) was investigated. 7 sites were studied, ranging in age from several weeks to 26 years. The change of abundance and species richness of ground beetle populations in a sequence of uneven-aged communities has a wavy character. These demographic parameters are high in three communities: pioneer (less than one year old), initial (age 2 years), and medial (age 26 years). Three communities which can said model ones for the above stages, are distinguished by their own set of preferential species with an increased density of populations in key habitats. For a quarter of a century of succession in carabidocenosis, the 3 types of the cenotic strategy (specific combinations of adaptive tactics) are gradually replaced in the following sequence: extreme pioneers → ruderal → stress-tolerants. The parameters of ground beetles population succession and the order of their replacement on the plain dump are radically different from the population of the dump with differentiation of habitats by mesorelief. In the conditions of the hilly-hollow relief, the composition and structure of the 25 year-old beetle population approached the native standards of the forest-steppe biome much closer than in the placer conditions of the leveled dump.
