Abstract. The article deals with the current issues of modern steppe management in the Orenburg-Kazakhstan cross-border region. The authors use the data of their own field research over the period of 2009-2014 aimed at detection and classification of model and secondary steppe ecosystems in the region. For the last 6 years it has been revealed that some steppe and fallow lands have different squares. The detected lands are multiple-aged and differ according to their qualitative composition depending on aged-specific (time for completion of agricultural activity), soil-lithogenous and floristic features.The authors detected sites of anthropogenic influence on steppe ecosystems as well as the factors that have favorable affect on restoration of natural ecosystems. The article also reveals the centers of restoration of traditional steppe fauna within the Orenburg-Kazakhstan region and the distribution area of marmot, little bustard, bustard, saiga antelope. The authors carried out the comparative analysis of agro-ecological situation in the region for a few last years as well as over long period of time according to archival and polling data.
Key words: model and secondary steppe ecosystems, fallows, steppe management, Orenburg-Kazakhstan cross-border region.
