Slovak forests have a great diversity and are mostly made up of native tree species. These forests have a precondition for the close to nature forest management. The application of close to nature forest management is more important when the living standard of the population is rising and when the climate is changing. For the correct application of management, we need to know the growth processes of forest trees. Therefore, we focused on the analysis of the age and increments of norway spruce in selected forests in Smolnícka osada. The aim of the work was also the reconstruction of spruce growth and analysis of the impact of climate on growth. In the forest, we selected 15 spruce trees from the lower, middle and over storey and they took samples of annual rings using a Pressler՚s borer. After analyzing the samples, we found that spruce in the select forest are of different ages (47-194 years) and have different diameter increments (0,6-3,5 mm). The trees of the lower and middle storey had the same range of incremets. These spruces had significantly lower increments than spruces growing in the over storey. After the reconstruction of the growth, we found that the increment of spruce in over storey has been declining since 2010. The average monthly temperature had a negative effect on the diameter increment and monthly precipitation had a positive efect. The climate affected the growth of spruce in June, July and August.
