Studies of pine phytocoenosis responses on heavy metal fallouts in field experiment

Evaluation of Scotch pine young woods responses on various man-made zink load levels simulated in a field experiment. Findings of studies of zink fallout controlled values.on pine stand condition index variations, needle biometric indicators, response of under canopy natural regeneration. Preliminary conclusions on values of maximum allowable industrial zink fallout for pine ecosystems based on principles of environmental approaches in man-made forest impact rating.
