| Description
| - The natural proportion of the Norway spruce cover is about 11 % in the Czech Republic and 50 % in the Norway. Norway spruce was in the past 200 massively introduced in the forest, because it is tree species with high production of the commercial wood. In the contrast to the native state, currently Norway spruce covers more than 50 % of the land. These pure spruce stands may be potentially unstable (especially on the sites with lack of available water). The composition of the tree species cannot be rapidly changed, because the rotation period of forest stands is usually longer than 100 years and these stands, alongside the bioproductive function, maintains also number of environmental functions (e.g. hydrological, recreational, health-hygienic). The wood is a renewable source and the industry is adapted on the Norway spruce type of wood. In the some branches of industry (e.g. paper and celulosis, wood-building) is not an alternative tree species, or the alternative is more expansive (e.g. make of furniture). One of the aims of the sustainable forest management is transfer of these potentially unstable spruce monocultures into the forest stand with better species composition. Because of the risk of ecological and bioproductive losses is not possible to leave these stands to the native evolvement. It is necessary to improve their ecological stability by the suitable silviculture treatments (to avoid e.g. similar situation as in the Sumava national park on the rest of the republic). The aim of the research should be supplementation of the current monitoring of the health state of the forest with the method enabling detection of the water stress of the trees. The incoming climate change will influence water cycle, hence the stability of the forest stands. In the combination with already used methods (e.g. defoliation, transpiration, photosynthesis, CO2 fluxes) will be possible to detect risk localities and make the survival analysis (en)
