FIELD: forestry, in particular, methods used on forest stock plots of forest lands in guard zones of aerial electric lines. ^ SUBSTANCE: method involves during laying out of novel aerial electric lines or clearing of cut-through of existing aerial electric lines, providing clearing works or forest isolating cut-through works on forest border adjoining thereto; carrying out reforming cuttings while changing spatial structure of plantations and enhancing suppressing effect of undergrowth to provide for inhibiting of growth of principal kinds of forest woods; organizing short-stemmed systems on borders adjoining to cut-through areas by cutting rotation, during which forest stand is felled at age not exceeding undergrowth rehabilitation maturity age. Because of short cutting rotations, forest in short-stemmed systems does not reach height hazardous for normal employment of aerial electric lines. ^ EFFECT: increased efficiency by eliminating probability of falling trees onto aerial electric line wires in forests of any kind with minimal allowable width of cut-through. ^ 1 cl |
