The main aim of the work was to determine difference in length of needles and annual wood increments of Pinus sylvestris L. and Picea abies L. on the dump-field and for comparison on referential site. We performed 500 measurements of needles for each tree species and for each study area. The annual wood increments were measured on wood bores from five tree individuals from each species and from both study areas – dump-field and referential site. Student t-test and indicators of central values evaluated differences of the measured attributes. The results show statistically significant difference at 99% level of confidence for both attributes – length of needles and annual wood increments. The results support the hypothesis about influence of heavy metals on the plants growing
