| Forests in Gwangneung National Arboretum District (GNAD) have been protected since the $15^{th}$ century. Consequently, these forests support more than 20% of all plant species in Korea. We constructed vegetation maps for landscape analysis, and forest dynamics, species diversity, and sustainable management were discussed. Secondary forests compose 51.0% of the whole vegetation, while plantations compose 45.2%. Quercus serrata dominates the forest, and the plantations are comprised mainly of Pinus koraiensis. Although dominated by plantations and human installations, the presence of a rare riparian hardwood forest, composed primarily of Q. aliena, was notable. Species diversity of the riparian (H' = 3.38) was significantly (p<0.0001) higher than the upland (H' = 1.56). Species turnover rate as a spatial heterogeneity was also higher. Such high species diversity and heterogeneity are justification to conserve the riparian and lowland forests in GNAD. Extensive recruitments of their own seedlings and saplings suggest a sustainable regeneration of Q. serrata and Q. aliena stands in the lower elevations, and the opposite is true for the Q. mongolica and P. rigida stands in higher elevations. GNAD contains diverse natural landscape elements that range from riparian to upland vegetation, which may well serve as a national model for forest restoration. |
