Birch, as one of the pioneer species, is a part of the preparatory forest, especially after extensive calamities. In the 1970s and 1980s, it most often served as a substitute stand in connection with the widespread dieback of forests as a result of the effects of air pollution. In recent years, it has become increasingly important in relation to the impacts of climate change. This paper deals with the comparison of selected quantitative and qualitative characteristics of two mixed birch stands at the age of 59 years, having the production and spa-therapeutic function, over a 30-year period. The results showed higher values of quantitative parameters (a number of trees, basal area, and merchantable volume) in the plot with the spa-therapeutic function. Qualitative production was slightly worse in the plot with production function.
