ABSTRACT
This paper summarizes our research work regarding the dynamics of vegetation growth of miscellaneous species of trees planted and monitored in the particular environment of the tailing pond in Bozanta Mare (Maramures County). The structure of soil bearing high content of heavy metals and cyanides considerably impacts the ecologic conditions of tailing ponds. Aspects related to soil characteristics (such as structure, size of particles, porosity, texture, chemical composition) are included. Vegetal species that have accommodated within the tail pond are included as well. In the framework of our experiment we have planted seedlings belonging to four species of trees: Quercus petraea, Populus tremula, Betula verrucosa, Salix caprea. We have planted the seedlings in different location contexts in the tailing pond (“in situ”), as we have also planted “ex situ” witness trees. Our aim was to monitor the dynamics of growth of the stem and of cuttings. Our contribution, based on the outcomes of our research, consists in the formulation of functional correlations spotted between cormophites and micro biota, between the species of trees and their environmental underlying conditions, with the overarching goal to optimize the activities undertaken in order to alleviate the tailing ponds inherent to mining activities.
