Condition of second-generation pine cultures in the former arable lands on the left bank of Seversky Donets river
Journal Title: Лісівництво і агролісомеліорація - Year 2012, Vol 120, Issue
Abstract
The results of studies of second generation of 1–20 years old pine cultures, created in former arable lands of the left bank of Seversky Donets River in State Enterprise “Volchansk forest Emterprise”, are presented. Studies indicate that the area of Scots pine plantations of the 2nd generation of poor sanitary condition significantly increases with age. Spread of Heterobasidion annosum in pine plantations of the second generation is substantially greater than in the first generation. In the third age class all pine plantations of the second generation are predicted to be affected with Heterobasidion annosum, resulting in significant loss of marketability and environmental protection functions of forest. Plantations in clear-cuts in root rot foci must be corresponded to soil conditions, and to be mixed pine-deciduous, taking into account the diversity of natural regeneration.
