This study was carried out to investigate the vascular plants of the protected area for forest genetic resource conservation in the National Yonghyeon natural recreation forest. The vascular plants collected 7 times (from February to September 2014) were consist of total 460 taxa; 95 families, 280 genera, 398 species, 3 subspecies, 50 varieties and 9 forms respectively. The 6 taxa of Korean endemic plants and 8 taxa of Korean rare plants were investigated. The floristic regional indicator plants found in this area were 43 taxa comprising 7 taxa of grade IV, 7 taxa of grade III, 12 taxa of grade II, 17 taxa of grade I. The naturalized plants were 39 taxa, therefore naturalized ratio was 8.5%. 460 taxa listed consist of 189 taxa (41.1%) of edible plants, 155 taxa (33.7%)of medicinal plants, 177 taxa (38.5%) of pasture plants, 52 taxa (11.3%) of ornamental plants, 17 taxa (3.7%)of timber plants, 12 taxa (2.6%) of fiber plants and 3 taxa (0.7%) of industrial plants. The vegetation status of investigated area was comparatively well conserved, but human-induced damage is increasingly greater. Therefore, a long-term monitoring of vascular plants and vegetation movement must become accomplished.
