Sodolinskyi R. The Maturity of Scots Pine Stands and Forest Use Optimization of Kyiv Region Forests

A dissertation is dedicated to investigation of Scots pine stands maturity based on their products structure and logging optimization within Kyiv region forests. Here more precise information-support tables of products structure dynamics of modal Scots pines stands were developed for Kyiv region forests. Considering revealed patterns maturity ages of Scots pine stands within forests of the various functional purpose have been examined, which is one crucial factor of forest use optimization among others. There is an analysis of the current and developed methods of annual allowable cut estimation presented. The last one proposed here is based not on the separated group of tree species, but rather on their complex and interaction within state forest enterprise. Such concept harnesses so-called ‘system effect’ as well. Validation of the new approach by current maturity ages using data of Boyarka Forest Station and Kyiv Forest Regional Unit has shown that annual allowable cut can be enlarged by area and growing stock volume up to 26–30 %, while a transition of forest production towards proposed method will support additional timber income of 150.6 thousands m3 within Kyiv Forest Regional Unit. Forest use plans based on the proposed approach by the projected maturity ages entail relatively lower results, but in 30 years annual allowable cut within entire Kyiv Forest Regional Unit will reach a normal state.
