This paper is based on results from assessment of the production characteristics development in sampling sets of forest management plans with the same date of validity and the validity period. Database is generated by basis sets of forest management plans valid from 1983. The aim of the analysis is to quantify and compare the development of production characteristics of the prevailing tree species in time levels and to quantify the impact of increasing growing stock. We have analysed the variables of the main crop: mean height, mean diameter, absolute yield class, current annual increment, growing stock and crop density. The result is a progressive, balanced and significant trend of increasing production characteristics, which confirms the results of the selection assessment and indicates increased and fast growth of Slovak forests in the research period. The analysis showed that increasing total growing stock is caused except increasing mean heights and mean diameters in particular by changes of the age structure that is reflected in increasing average age of the area.
