Abstract. In the old-developed region and habitats of Bryansk region, the question of selection species forming communities on substrates extremely disturbed by anthropogenic activity is being actively investigated. An actual trend is considered to be the selection of adventive species that naturalize in disturbed habitats and serve not only as valuable bioindicators of various disturbances and disruptions in the landscape but can also be potentially considered for revegetation technologies in the remediation of technogenically disturbed soils, including the restoration of agricultural lands. Methods. The research employed several methods: a route method, a trial plot method, the J. Braun-Blanquet geobotanical method, and a succession diagnostics method. Soil composition was determined using laboratory-chemical analyses. The purpose of this article is to substantiate the specific features of the species composition of phytomeliorants in successional processes on technogenically disturbed habitats in the southwestern Non-Black Soil Zone, which are potentially promising for the technology of grassland establishment on disturbed soils. Scientific novelty. For the first time in the studied region, the peculiarities of demutation successions during the overgrowth of quarries and dumps have been identified, which allowed for the recommendation of the most promising species for phytoremediation. Results. It was established that the species composition of herbaceous plants discovered during shifts in the developed space of quarries and waste dumps after the extraction of non-metallic minerals is enriched over time. Grassing processes, which are registered at the second and third stages of quarry and dump overgrowing, indicate the formation of stable plant compositions capable of transforming the environment and ecologically “restoring” habitats. Generalised data on the structure, ecological features of adventive neophyte species adapted to ruderal habitats, which can potentially be included in the list of promising for grassing technology, showed that communities of Anisantha tectorum, Oenothera biennis, Festuca arundinacea, developing on extremely disturbed substrates are predicted to be used in the stage of biological reclamation. Adventives of three species cause changes in enzyme activity of soils: all established indicators for urease, catalase and cellulase allow to refer soils to medium enriched soils. When comparing enzyme activity in soils under adventitious neophyte communities with soils in natural meadow communities, the activity values are increased. The increase in cellulase activity is explained by the stimulation of bacterial diversity during the formation of adventitious biocenoses.
