The aim of the article is to evaluate the development of plantations of differently performing parts of the mountain spruce population in the area with high nitrogen deposition. The high nitrogen compounds load threats the stability of the forest stands and consequently affects the forest functions on mountainous sites over long time. An important measure to reduce the sensitivity of forest ecosystems is also the support of a high level of biodiversity. This means a maintenance of intraspecies variability within populations. The first results of the experiment were in accordance with previous experience with other mountain spruce populations as the initially slower-growing seedlings showed the best growth and health after being planted in mountain conditions. On the basis of these results it is still possible to hypothesize that one of the options to reduce the negative impact of nitrogen in mountain climates lies in that artificial restoration strategy that does not eliminate the category of initially slowly-growing spruces.
