The Use of Conifers for Planting Protection Zones

Abstract

The present-day expansion of utilization of natural resources makes it necessary to coordinate the increase in industry with its effects on ecosystems. In connection with this, the principal tasks are, first, to heal the wounds suffered by nature by means of forest culture and natural reafforestation processes and, second, to enhance the ability of woody plants and forest communities to accumulate pollutants and detoxify the atmosphere (Kulagin 1980; Liebold and Ranft 1981). This can be done by selecting individual gasresistant trees, establishing plantations of gas-resistant clones and choosing relatively gas- and smoke-resistant ecological populations. The latter method is the most popular as it saves time and reduces the expense of producing plant material that is resistant to industrial pollution.
