Scheduling of timber production and economic analysis of Pinus densiflora and Quercus species for sustainable management in private forest in Korea: focused on Jinan-Gun

摘要

This study was carried out to investigate the potential of timber production in private forest that is typically small in size, and to schedule timber yield for sustainable forest management. The study target areas were 1424?ha of Jinan-gun pioneer forest management sites in Jeollabuk-do, Korea. To schedule the timber yield, analysis and statistical processing were conducted based on materials obtained from the Forest Resources Inventory Center of the National Forestry Cooperatives Federation. The timber yield schedule, which induced legal forest state using the concept of maturity based on resource analysis, showed that total maturity level of Quercus species was 2108.5. The total maturity level of Pinus densiflora at that time was 1335.4, which was higher than 1316, the total maturity level under legal state. By suggesting solutions of systematic management through private forest management scaling, for private forest promotion equivalent to 68.1% of Korean forest, the economic feasibility on timber yield simulation was developed. In the economic analysis, the net present value (NPV) of Quercus species was 1410 billion KRW. The benefit–cost ratio (BCR) was 2.0 and Pinus densiflora was 3150 billion KRW in NPV and had a BCR of 4.0, showing economic feasibility.
