SUBSTANCE: method involves a division of the protection zone into three parts - a central and two lateral, complete destruction of trees and shrubs in the central part and selective destruction of trees and shrubs in the lateral parts. In the lateral parts of the protection zone of main pipeline the selective destruction of trees and shrubs is performed while keeping and planting on the edges of forests of trees and shrubs, which habit of crown, taking into account future growth for 10-15 years, will be located within the boundaries of the lateral parts of the protection zone.
