Biological remediation of roadside areas

During the construction of highways, significant damage is caused to the environment: the soil cover is degraded, vegetation cover and the natural landscape are destroyed. The issue of minimizing the negative impact of this direction on the environment was not given enough attention. Therefore, one of the main issues of environmental protection is the timely implementation of works on reclamation of disturbed lands. Land areas of temporary allotment for road construction that are subjected to mechanical impact after the stage of technical reclamation are subject to biological reclamation, which is aimed at landscaping the roadside area. To achieve these goals, we used the method of developing measures for the reclamation of disturbed land during the construction of the highway. Activities on biological remediation can be performed as a result of: the serial complexity of the species composition of plant communities, which has long co-exist with man-made recultivated territories; the launch of the rehabilitation process which can be carried out simultaneously in a multispecies complex of phytocenosis, suggesting further its sustainable functioning. As a result of biological reclamation measures, using crops that are resistant to pollutants and meliorants, it is possible to gradually reduce the content of pollutants in the soil due to natural self-cleaning processes as a result of removal of elements by plants and their leaching outside the root layer of the soil.
