Change of indices of forest inventory for pine stands damaged by different causes
Journal Title: Лісівництво і агролісомеліорація - Year 2013, Vol 122, Issue
Abstract
Change of indices of forest inventory was evaluated for pine stands damaged by Diprion pini L. and ground fire after 10 years after action of these causes, as well as in the chronic focus of root rot for the same period. In the focus of Diprion pini for 10 years after heavy defoliation, relative density decreased by 0.08 unit, but stayed high (0.81). Cross-section of the stand was inferior to control by 2.3 %, wood stock – by 4 m3/ha (0.8 %). In the focus of root rot, relative density decreased by 0.05 unit, cross-section of the stand – by 0.8 m2/ha. Wood stock in 2012 was inferior to control by 23 %. In the plot after ground fire relative density decreased from 0.78 to 0.39 unit (by 49.3 %), cross-section of the stand – by 47.2 %, wood stock – by 46.7 %.
