The purpose of this study was to evaluate the effect of rehabilitation measures on the fired woodland of Chesuk-bong in Mt. Chiri through the vegetation structure and comparison of growth pattern between natural seedlings and transplanted Abies koreana seedlings. It was also discussed the rate of standing and fallen trees of dead conifers in the management strategy for vegetation regeneration and protection of sub-alpine area. In this fired woodland, shrub layers consisting of Weigela subsessilis, Sambucus williamsii var. coreana, Rhododendron schlippenbachii, R. mucronulatum, Tripterygium regelii, and etc. were gradually expanded, and tree species such as Betula ermani, Sorbus commixta, Acer pseudosieboldianum, and Malus baccata var. mandshurica were also regenerated. The growth of height and crown width of Abies koreana seedlings transplanted for vegetation regeneration were a little lower than those of natural seedlings. The seedlings of A. koreana transplanted in this fired woodland grew about 50.6% normally, but the others had multi-branched or growth stopped by death of terminal shoot. Because the number of dead conifers by fire tend to be gradually increased as time passed, it can occurs to the soil erosion and landslide by weakness of the cohesion and resistance of soil. Therefore, it is consider that rehabilitation measures projects of the fired woodland in subalpine area may be more prevention a natural disaster like soil erosion, flood and landslide.

Forest fires happened simultaneously in Go-Seong, Gang-Neung, Sam-Cheok, Dong-Hae, Ul-Chin for 9 days(7th-15th of April, 2000). The area of those fires came to 23,794ha, about 80 times of Yeoui-Do and the extent of damage was the biggest and worst in Korea. The focus of this study is to compare the rate of restoration by damage types and develop the sound restoration model and efficient woodland management after the forest fire. The study site faces East Sea and the elements such as seasons, topographical features and etc. make difficult to obtain the suitable data from satellite. This study analyzed two images;2000yr and 2001yr after the fire. MODVI was more useful to grasp the damage than NDVI and the limitation of this study was the lack of images by damage types. The study suggests that lots of images are needed to monitor and analyze the forest fire site and the image of higher resolution is required to analyze the narrow site.
