This work analyses the ambient ozone concentrations measured during 1999-2008, parallel on two research plots differing in their vegetation cover (beech forest stand and open plot), situated in a rural area. There was detected a difference in the ozone concentration values between the two plots due to their spatial arrangement, but this difference was not significant. On the other hand, a noticeable statistically significant difference in ozone concentrations and differences in selected climatic variables were observed. The influence of average temperature and of rainfall sum was very significant, at p < 0.0001. The variability of the measured ambient ozone values ranged from 50.01% in the stand to 57.36% on the open plot. Ozone maxima occurred frequently, mainly after the year 2004. The increase in ozone concentrations, primarily in form of extreme events, means a serious risk for the environment.
