A Change and Distribution in Pinus densiflora Forest of Mt. Hallasan

Abstract

This study was carried out to investigate the distribution and their change of Pinus densiflora forests by climate change in Mt. Hallasan. The results showed that the areas of P. densiflora forests of Mt. Hallasan varied by region, with a total area of 1,324.3 ha, concentrated mostly in the region 1,000 m -1,400 m above sea level. The temperate coniferous forest zone are distributed in the upper part of temperate forest zone composed of deciduous broad-leaved trees. Most of the P. densiflora forests in the lower parts were found not to be spreading because they are located close to the deciduous broad-leaved trees. However, the P. densiflora forests in the Sajebi and Pyeonggwe regions composed of the grasslands and shrub forests were found to be spreading. In addition, the altitude of the P. densiflora forests distribution increased by about 50 m and 90 m in the Sajebi and Pyeonggwe regions, respectively. The spread rate is expected to become faster than in the past due to the rate of climate change. The structure of the vegetation in Mt. Hallasan and the changes in the vegetation due to various factors need to be investigated from a long-term point of view.
