Abstract
Toxic waste from tailings dumps, as a result of erosion processes, can cause significant environmental damage through the migration of pollutants. This leads to the degradation of forest ecosystems, since heavy metal and arsenic compounds are absorbed by plants and soil. The purpose of the work is to assess the state of natural forest vegetation near a man-made source and determine the resistance of forest species in the stand and undergrowth to heavy metal pollution. To assess the state of natural vegetation, 4 test plots were laid taking into account the vegetation on strip counts. According to chemical analysis data, migration of heavy metals from the soil and litter to tree needles is noted. According to the assessment of the state of forest stands, 55 % of all studied species can be classified as weakened and drying out. The article provides an inventory characteristic of tree species and undergrowth near the Vysokogorskiy tailings dump on the territory of the Kavalerovskiy forestry of Primorskiy Krai. The obtained data on the state of the forest stand and the chemical composition of the components of the forest ecosystem made it possible to determine the resistance of various forest species to the impact of unfavorable factors.
