Description
On the example of middle-aged and mature valuable forest stands we have brought an assessment of forestry and economic efficiency of various options of silvicultural actions for the reconstruction of invaluable young growths (17 objects with a total area of 102,6 hectares) which was carried out in 1947-1959 and to formation of plantings from subgrowth and young growth of the coniferous breeds kept when carrying out gradual and continuous cabins in 1962-1996 and also from forest cultures (8 objects of 44,9 hectares) for conditions of the coniferous and broad-leaved woods of the Republic of Tatarstan. The results of the researches showed that the best indicators of forestry and economic efficiency of actions of care of the woods by reconstruction are observed in pine plantings at a continuous way: the grown-up wood reserves on a root (346-522 m3/hectare in 55 years) exceed stocks of modal forest stands on 109-288 m3/hectare with economic efficiency within 10625-50659 rub/hectare. Slightly less efficient - larch and spruce plantings at a corridor way of reconstruction. Similar indicators of actions for formation of plantings from subgrowth represent positive results as well: forestry efficiency made from 31 to 208 m3/hectare, economic - within 10584-26846 rub/hectare. Based on the researches we made conclusions, offers and recommendations for practical use in forestry of the Republic of Tatarstan
