The Świnia Góra nature reserve was established in 1938 to protect natural forest phytocoenoses. It was studied between 1964 and 1969 and during this investigation almost 350 species of vascular plants were documented. After 40 years of strict protection the studies were repeated to describe the nature reserve's flora dynamics.
A considerable decrease in number is particularly observed in the case of species belonging to Molinio- Arrhenatheretea, Nardo-Callunetea, and Scheuchzerio-Caricetea nigrae. The disappearance of representatives of the above socioecological groups is a result of increasing forest glade succession. Statistically relevant changes also have been noted as regards the trophic status of the nature reserve's flora, based on ecological indicators. The higher the status, the more extensive the eutrophication of the forest habitats.
