Evaluating stumps volume in managed, protective pine stands of the subtaiga forest-steppe region of Middle Siberia

Abstract

The article evaluates the stump reserves in pine forests of the subtaiga-forest-steppe region of Central Siberia. It was found that in stands with high density (relative density above 1.0) and high productivity (I– II productivity classes), the stump stock ranged from 0.23 to 2.21 m3 per ha 1. The proportion of stump wood in the total timber stock ranged from 0.04% to 0.44%. The majority of stumps (39.1%) were in the 2nd decay class, indicating that the silvicultural practices used in the area were implemented over a decade ago. The mass of stumps ranged from 0.07 to 0.70 t per ha-1, while the stump carbon reserve varied from 0.04 to 0.35 t С per ha-1 .
