Anthropogenic changes in selected elements of the natural environment in the Lisia Gora forest nature reserve in Rzeszow

The paper presents an analysis of selected environment elements, which were subjected to anthropopressure in the Lisia Góra forest nature reserve, located within the city of Rzeszów (SE Poland). The main aim of the study was to indicate the intensity and forms of anthropopressure within the relief, soil and vascular flora. Changes in the relief were shown for the period 2010−2019 using the analysis of geomorphological processes and the mapping of anthropogenic terrain forms. Additionally, the litter in the reserve was examined. Soil studies were performed with standard methods in 2016, and the degree of anthropopressure was shown particularly through the parameters of soil compaction and acidification. Changes occurring within the vascular flora were determined by means of anthropogenic indicators of flora changes in the time horizons 2002 and 2016. The results of the studies indicate degradation processes of the studied environment elements in the reserve
