The Ukrainian feather-grass steppe ecosystems are highly vulnerable to climate changes.

The results of multiple regression analysis showed the major components that influenced the ANPP at each of the study plots ‘Plain’, ‘Slope’ and ‘Lowland’. The precipitation and relative humidity in the months before the vegetation peak were most important for ANPP accumulation.Results of this study are important for the prediction of ecosystem changes under the climate changes and also for the development of nature conservation programmes.
