The article summarizes methods used and results obtained by Czech scientist in studies of effects of climate changes on plants from cold, i.e. alpine and polar, regions. For vegetation development studies, palaeobotanical analyses and repeated locality survay are used. Analysis of plant macrofossils proved presence of Salix herbacea in Central Svalbard. Vegetation mapping of Adolfbukta locality did not prove any significant changes in plant communities durinl last 70 years. Experiment using repeated survays was established in the Himalayas. Plant growth is studied using herbochronology providing thid data for climate reconstruction. Effect of mild warming on plant communities is simulated in open-top chambers. Mild warming affected lichen community structure and led to elongation of vegetation period. Plant altitude distribution and its limits are tested using tranplantation experiments in the Himalayas where shift in elevation was observed.
