Needle traits of P. sylvestris exhibit high variability depending on habitat conditions and thus may be used to assess the effect anthropopressure tree condition in this species. The 22 needle features Scots pine, collected from populations growing at different distances Bełżec-Podlesina eolian sand mine located Poland, was investigated. No similar research has been conducted date. needles were 40 trees four study plots a distance 205.281 997.598 m mine. In total, 3460 117 samples measured. It observed that had statistically significant all analysed traits, with most extreme values recorded for coming distant characteristics greatest importance assessing impact studied included: length/needle width, length, thickness, number stomata convex side needle/needle width/resin duct diameter, resin concave length needle. given plot depended age needles. analyses confirmed despite adaptability pine local environmental conditions, morphological anatomical its changed under influence anthropopressure. Thus, selected assimilatory organs monitor opencast operations important forest-forming
