For environmental risk estimation of Norway spruce ecosystems under climate change, the space means for each „forest vegetation degree“ in the frame of all so called „natural forest areas“ basic climatic characteristics (above all mean daily diameter, daily precipitation sum) and two climatic extremes (number of days with daily precipitation sum < 1 mm, number of days with maximum temperature > 30 oC) were computed. Aggregate typological units, as“forest type sets” and “management types” in combination with “forest stand types”, were used for environmental risk estimation at „natural forest areas“ and whole Czech Republic levels. Endangered forest stands, occurred in given “forest type set”, „forest vegetation degree“ and „natural forest area“ were estimated using comparison of basic and derived climatic parameters between all 5 time period (1961–2099). Measured data from climatic stations were used for the period A (1961–1990) and B (1991–2009); for periods C (2010–2039), D (2040–2069) and E (2070–2099) the data were modeled by climatic model ALADIN-Climate/CZ. This procedure enabled to distinguish all „natural forest areas“ into “warm” ones, which do not meet requirements for ecological conditions of Norway spruce at present period B and “cold” ones which meet them
