XVI International Botanical Congess

The dumps of firm household scraps occupy the significant area in Donetsk region. Successions of vegetation in these territories are differed from similar processes in many others technogenic ecotopes. The vegetation communities of classes Chenopodietea and Artemisetea vulgaris prevail in the beginning of succession. In the further, they are replaced by community of class Agropyretea repentis. The communities of zonal vegetation are formed for 30-40 years and they are submitted by coenoses of the class Festuco-Brometea. Phytocoenoses get high stability to occurrence of adventive species at this stage. The significant acceleration of restoration process of steppe vegetation is possible by introduction of corresponding species.
