Abstract
The Specific Plant Species such as N degree (2 species) and V degree (5 species) which is categorized by the Ministry of Environment are appeared as 7 species. II degree species among Endangered species of wild flora is Abeliophyllum distichum, and the Rare and Endangered Species which is categorized by the Korea Forest Service are enlisted as the five taxa. The Bukhansan is one of the phytogeographic ally important areas among national parks of Korea because this region is located in the northern limit of Southern Plant Types, such as Carpinus laxiflora, Cornus kousa, Styrax japonica and Zanthoxylum piperitum. The flora of the area was enlisted as 638 taxa, 103 families, 362 genera, 541 species, 87 varieties, and 10 forms. Naturalized Species was identified as 58 taxa, 16 families, 52 genera, 54 species and 4 varieties. The Ratio of Naturalized and Urbanization Index was 9.09% and 20.21%, respectively.
