Sažetak
The recent and coming development of forestry practices in Northwest Russia includes fast implementation of cut-to-length (CTL) harvesting, transfer of technology, introduction of commercial thinnings and energy wood harvesting. The market size for industrial and energy wood harvesting machinery was assessed for the Leningrad region. The logging machines fleet consisted of about 700 machines for traditional tree-length technology and 120 harvesters and forwarders for CTL technology. The domestic machinery fleet is obsolete; manufacture of domestic forest machinery has dropped in both quantity and models, and thus imported CTL machinery is replacing domestic tree-length machinery. The results indicate that the market for CTL machinery could be 21 harvesters, 32 forwarders and 26 short-wood trucks per year and could increase to up to 30 – 40 machines each in the future. The maximum need for the machinery in the Leningrad region could be 50 – 60 harvesters, forwarders and short-wood trucks per year if allowable cut and commercial thinnings were realized in full scale. The market for energy wood harvesting machinery could be 4 biomass forwarders, 11 mobile chippers and 13 wood chip trucks per year and could be 6 and 15 – 20 machines per year in the future, respectively. The maximum need could be 30 – 40 biomass forwarders, mobile chippers and wood chip trucks per year. Only one third of the logging enterprises in the region had enough leased forest resources for applying the highly productive mechanized CTL technology. These 41 forest enterprises would need 270machines, consisting of 90 harvesters, 100 forwarders and 80 short-wood trucks. Thirty-seven enterprises would need about 50 biomass forwarders and chippers and 60 wood chip trucks for energy wood harvesting. Sixty percent of the forest leasers had enough forest resources and could be users of Nordic CTL technology if allowable cut was utilized completely and if commercial thinnings were done in full scale. These 68 enterprises would need about 500 conventional logging machines, consisting of 160 harvesters, 190 forwarders and 150 short-wood trucks, and about 300 energy wood harvesting machines, consisting of 100 biomass forwarders, 100 chippers, and 110 wood chip trucks. In addition, the ten largest enterprises would need half of the total fleet.
