However, many studies contributed to the knowledge about relation on forest resiliency and environmental, emission-ecological especially, factors. Climate, exposition, weather extremes and bark-beetles play great role for these relations in the Central European mountain spruce forests. Data quality about soil has been restricting any theory about feedbacks between site and tree species ecology. We selected the research forest plots at base as well as near mountain ridge and on exposed isolated peak plateaus of Giant Mts. and Radhošťská Highlands (Kněhyně). There we located the mapping areas about 1 hectare of continuous area at basic network 5 x 5 m. In conditions of mountain ridge in Giant Mts. there was recognized a pattern with significantly different soil types. Histosols and Gleysols were dominantly presented at parts of the base ridge (Alžbětinka: total 17 soil subtypes per hectare). Haplic Podzols, Skeletic Podzols and Haplic Leptosols were mainly dominated on the parts of mountain ridge (Modrý důl: total 20 soil subtypes per hectare). Peak plateaus (Svorová hora Mt. and Kněhyně Mt.) were dominantly characterized by Histic Podzols, Haplic Podzols and/or Skeletic Podzols. Histosols were detected only in small local depressions. In less exposed parts of the Kněhyně Mt. Dystric Cambisols were observed too (total 22 soil subtypes per hectare). These results demonstrate that soil heterogeneity is significantly high due to various sensibilities of mountain soils to any stress (mostly to natural disruptions). Until data collection about ecology research of mountain forests does not include site heterogeneity of soils, results will always be restricted by using of approximate approaches. Empirical knowledge about soil heterogeneity could to solve some attributes of uncertainty associated with local soil survey.
