No natural ecosystems can be found within the areas subject to anthropogenic changes. Neither there is any return to primeval ecosystems. While there is a need to naturalise the way of using the environment, in particular that in the areas degraded or threatened by degradation. The phytomelioration of landscapes anthropogenically changed may be effectively carried out solely on the basis of programmes resulting from the knowledge on socio-economic needs and natural and technical conditions. The development of such a programme shall necessarily be preceded by an indepth analysis of natural conditions with special emphasis on evaluating the extent of degradation and potential threats within a given area. It is assumed that any surface free from technical build-up shall have some ecological function in addition to its economic functions. Forest reclamation of grounds which are either non-effective as agricultural land or degraded by mining industry, industrial pollution and waste disposal - constitutes an important task, regretfully implemented to an unsatisfying degree.
