The High Sudetes represent an important phytogeographical link between the floras of the Alps and Scandinavia, being a refuge for a wealth of arctic-alpine species. Though they might belong to the bryofloristically best-explored regions of the world, the most floristic data date back to the last century and have not yet been comprehensively and critically compiled.The authors are carrying out an intensive bryological survey with the aims of a) the critical evaluation of the historical bryofloristic data of the summit areas of the Krkonoše and Hrubý Jeseník Mts., b) the systematic bryofloristic inventory at the selected localities ? biodiversity centres of the High Sudetes and c) the synthetic evaluation of both recent and historical data.
