A Modelling System for Dead Wood Assessment in the Forests of Northern Eurasia

Dead wood, including coarse woody debris, CWD, and fine FWD, plays a substantial role in forest ecosystem functioning. However, the amount dynamics of dead wood forests Northern Eurasia are poorly understood. The aim this study was to develop spatially distributed modelling system (limited territories former Soviet Union) assess structure by its components (including snags, logs, stumps, dry branches living trees) based on most comprehensive database field measurements date. is intended be used volume carbon units as part budget calculation at different scales. It presented using multi-dimensional regression equations expansion factors (DWEF)—the ratio component growing stock stands. can also for accounting national greenhouse gas inventories UNFCCC reporting. system’s accuracy satisfactory average level disturbance regimes but it may require corrections regions with accelerated regimes.
