Productivity Indicators and Standards of Spruce Crowns in the Northern Taiga

Abstract

Resources of small-size wood, particularly wood of tree branches can be a significant addition to the raw materials used in processed form. However, accounting and forecast of such wood resources is not implemented in forest inventory practice yet. This is largely due to lack of forest valuation standards - assortment and commodity tables with additional information about the wood branches resource.

Calculations with the use of such standards or models developed here will significantly improve the evaluation accuracy of the potential biological productivity of tree crowns.
