FIELD: forest industry. ^ SUBSTANCE: method involves dividing plots into swaths; providing logways; felling trees intended for cutting with their apexes oriented in logging direction, followed by logging thereof; performing thinning of semi-swaths by cutting corridors at an angle of 30-35 deg with respect to logway, with desired thinning extent being reached by providing corridors cut from adjacent logways. Corridors cut from adjacent semi-swaths intersect with one another to form plantation of mosaic structure where cells are defined by cut corridors. With employment of tree harvesting machines having load-bearing handler, 2-3 corridors are cut from one operating position, with 2 corridors from said 2-3 corridors being cut at an angle of 30-32 deg, and third additional corridor being cut perpendicular to logway. Working out of swath by intersecting corridors provides tree stand thinning without injuring of trees left for additional growing. ^ EFFECT: provision for creating of effective forest growing conditions and desired thinning extent without tree injuring. ^ 2 cl, 3 dwg, 1 tbl |
