  • The flora of the vascular plants in Deoksesan Mt. and its adjacent areas, located at Inje-gun, Gangwon province, were surveyed for a total ten times from April of 2018 to July of 2020. The result of this survey revealed 457 taxa, consisting of 90 families, 287 genera, 404 species, 13 subspecies, 35 varieties, and 5 forms. Among them, 12 taxa were endemic plants to Korea, and 7 taxa were rare plants. Red list plants and those designated as controlled Korean biological resources, requiring special permission for export outside of the county, numbered 3 and 103 taxa, respectively. The floristic target species amounted to 83 taxa, specifically 8 taxa of grade IV, 26 taxa of grade III, 21 taxa of grade II, and 28 taxa of grade I. In addition, 14 taxa were classified as plants adaptable to climate change, and 4 taxa at their respective northern limits, first recorded in this study, were also investigated. Twenty-nine taxa of alien plants and 4 taxa of ecosystem disturbance species were also found in this area. Our results suggest that some species should be preserved and can serve as basic information with which to establish data on the preservation of resources, such as plant diversity and distributional changes on Deoksesan Mt.

The vascular plant were collected 13 times (from March to October 2011), and 384 taxa in total were identified, including 94 families, 260 genera, 340 species, 5 subspecies, 37 varieties and 2 forms. Korean endemic plants of this area were nine taxa; Clematis brachyura, Rhododendron mucronulatum, Forsythia koreana, Paulownia coreana, etc. Rare plants (IUCN) by the Korean Forest Service and Korean National Arboretum three taxa were recorded; one Critically Endangered species (CR), Prunus yedoensis, one Vulnerable species (VU), Epimedium koreanum, one Least Concemed species (LC), Phacelurus latifolius. The floristic regional indicator plants found in this area were 15 taxa comprising two taxa of grade V and III, one taxa of grade II, 10 taxa of grade I. Furthermore, therophytes (28.3%), hemicryptophytes (23.0%), hydrophytes (14.3%) showed high proportional ratio in life form spectrum. The naturalized plants were identified as 43 taxa and the percent of naturalized index (NI) was 11.2% of total 384 taxa vascular plants. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by the disturbances of human beings. Therefore, a long-term monitoring of vegetation changes and movement grasp must become accomplished.
