Abstract
Over the last 30-45 years, changes in some characteristics of climatic factors have been observed in the Akmola region (increase in average annual temperature, rainfall, etc.). Seasonality of biological phenomena, phenology, is directly dependent on such changes. In the course of studies conducted in the last decade of September 2013, 2016 and 2018, in the area surrounding Kokshetau city, 37 species of flowering wild plants were found, flowering of most of which were not typical of this period. In 70% of the detected flowering plants, significant shifts in flowering phenology were observed, and in some species, re-flowering was observed. There have also been registered cases of increased flowering time. The article discusses the relationship between shifts in the phenology of flowering of some wild plant species with climatic factors.
