In order to investigate vertical plant distribution on Jungsanri of Mt. Jirisan by temperature change, vascular plants of fourteen areas with 100-meter-high difference were surveyed from the Jungsan bridge(348 m alt.) to the Jangteumog(1653 m alt.). A total of 440 taxa belonging to 104 families, 287 genera, 385 species, 7 subspecies, 42 varieties, and 6 forma were vegetated on survey areas. Around 700 m high did species diversity of vascular plants decrease rapidly, but foreign species were not found. The Detrended correspondence analysis(DCA) divided distribution of vascular plants into five groups; areas below 500m alt., 500~600m alt., 600~1000m alt., 1000~1200m alt., and areas above 1200m alt.. These results showed that vegetation of vascular plants on investigated areas has high correlation with climate elements of temperature. Vascular plants should be crowded within their own optimal ranges of vegetation. Climate change would result in shift of these distribution ranges, and thus vegetation shift will be happened accordingly.

Distribution of vascular plants in Yangyang-gun were investigated 12 times from Apr. to Sept., 2008. In the result of survey, the flora of this area consist of 412 taxa totally; 89 families, 259 genera, 366 species, 5 subspecies, 37 varieties and 4 forms. There were remarkable plants such as 11 taxa of Korean endemic plants, 58 taxa of specific plants which were designated by the Ministry of Environment, 2 taxa of endangered plants of Ministry of Environment, 7 taxa of rare, endangered plants of Korea Forest Service and 28 taxa of afforestation plants and 296 taxa of useful plants. Furthermore, 36 taxa of naturalized plants (8.74%) were also observed in this area. Vegetation of investigated area was conserved well. However, vegetation has been destroyed rapidly due to construction of commercial complex for human recreation such as condominiums and stores. Therefore, it is need to efficient management of the water quality and vegetation by conservation strategies from huge visitors.

This study was carried out to investigate the distribution of vascular plants and their usefulness in Mt. Ilsan (Hwacheon-gun, Gangwon-do). The vascular plants were summarized as 496 taxa; 91 families, 295 genera, 422 species, 1 subspecies, 58 varieties, and 15 forma. Among the investigated 496 taxa, 17 Korean endemic, nine rare, and one endangered plants were included. Based on the list of the species of specially designated plants by the Ministry of Environment, 66 taxa including Hanabusaya asiatica and Aconitum koreanum were recorded in the investigated area. The naturalized plants were identified as 27 taxa and the percent of naturalized plant species(PN) was 5.4% of all 496 taxa vascular plants. Usage of 496 taxa were consists of 201 taxa(40.5%) of edible plants, 168 taxa(33.9%) of medicinal plants, 69 taxa(13.9%) of pasture plants, 61 taxa(12.3%) of ornamental plants, 17 taxa(3.4%) of timber plants, 16 taxa(3.2%) of fiber plants and 4 taxa(0.8%) of industrial plants.

The climate is changing rapidly, and this may pose a major threat to global biodiversity. One of the most distinctive consequences of climate change is the poleward and/or upward shift of species distribution ranges associated with increasing temperatures, resulting in a change of species composition and community structure in the forest ecosystems. The Baekdudaegan mountain range connects most forests from the lowland to the subalpine zone in South Korea and is therefore recognized as one of the most important biodiversity hotspots. This study was conducted to understand the distribution range of vascular plants along elevational gradients through field surveys in the six national parks of the Baekdudaegan mountain range. We identified the upper and lower distribution limits of a total of 873 taxa of vascular plants with 117 families, 418 genera, 793 species, 14 subspecies, 62 varieties, two forms, and two hybrids. A total of 12 conifers were recorded along the elevational gradient. The distribution ranges of Abies koreana, Picea jezoensis, Pinus pumila, and Thuja koraiensis were limited to over 1000 m above sea level. We also identified 21 broad-leaved trees in the subalpine zone. A total of 45 Korean endemic plant species were observed, and of these, 15 taxa (including Aconitum chiisanense and Hanabusaya asiatica) showed a narrow distribution range in the subalpine zone. Our study provides valuable information on the current elevational distribution ranges of vascular plants in the six national parks of South Korea, which could serve as a baseline for vertical shifts under future climate change.

In order to investigate vertical plant distribution on Osaek valley of Mt. Seorak by temperature change, vascular plants of fourteen areas with 100-meter-high difference were surveyed from the Osaekgyo(345m alt.) to the Daecheongbong(1708m alt.). A total of 449 taxa belonging to 94 families, 279 genera, 397 species, 5 subspecies, 45 varieties, and 2 forma were vegetated on survey areas. Around 500 m high did species diversity of vascular plants decrease rapidly. The Detrended correspondence analysis(DCA) divided distribution of vascular plants into five groups; areas below 500m alt., 500~900m alt., 900~1400m alt., 1,400~1,600m alt., and areas above 1,600m alt.. These results showed that vegetation of vascular plants on investigated areas has high correlation with climate elements of temperature. Vascular plants should be crowded within their own optimal ranges of vegetation. Climate change would result in shift of these distribution ranges, and thus vegetation shift will be happened accordingly.

In this study, we investigated the vertical distribution and vascular plants on Joryeongsan Mountain in Baekdudaegan, Korea. The results of four field surveys from April to September 2023 identified a total of 552 taxa, representing 491 species, ten subspecies, 43 varieties, six forms, and two hybrids in 314 genera and 101 families. The elevational distribution ranges of 360 taxa of vascular plants were also identified. Among them, 19 taxa were endemic to Korea, and two taxa were rare plants. The floristic target plants amounted to 100 taxa, specifically two taxa of grade V, seven taxa of grade IV, 25 taxa of grade III, 33 taxa of grade II, and 33 taxa of grade I. Seventy-eight taxa were northern lineage plants. In all, 29 taxa of alien plants were recorded in the investigated area, with a naturalized index of 5.3% and an urbanization index of 7.4%. Two plants disturbed the ecosystem. Species richness along the elevation showed a reversed double-hump shape with peaks at low, mid, and high elevations. The results of a cluster analysis showed a high degree of similarity between adjacent elevation sections, except in lowlands. Detrended Correspondence Analysis ordination also supported distinct groups by elevation. Warmth index values ranged from 62.1℃·month to 92.9℃·month on Joryeongsan Mountain. Our results provide primary data on vascular plants and valuable information on the current distribution ranges of plant species on Joryeongsan Mountain. These data could serve as a baseline for comparing species shifts at elevations under future climate changes.

This study was conducted to investigate the vertical distribution and vascular plants in the Gakho mountain. Form the results of three field surveys from May 2022 to September 2022, a total of 478 total taxa, representing 426 species, 11 subspecies, 35 varieties, four forms, and two hybrids were identified, which were categorized in 282 genera and 94 families. We identified the elevational distribution ranges of 398 taxa of vascular plants. Among them, 19 taxa were endemic to Korea, one taxon was identified as a rare plant. The floristic target plants amounted to 72 taxa, specifically two taxa of grade V, two taxa of grade IV, 16 taxa of grade III, 27 taxa of grade II, and 25 taxa of grade I. Further, 71 taxa were identified as northern lineage plants. A total of 19 taxa of alien plants were identified, with a Naturalized Index of 4.0%, an Urbanization Index of 6.6%, and three plants that disturbed the ecosystem. The result of analyzing the pattern of species richness showed a reversed hump shape with minimum richness at mid-high elevation. A cluster analysis showed a high degree of similarity between adjacent elevation sections that are geographically adjacent with similar habitat environments. Warmth index in the Gakho mountain ranged from 57.2℃·month to 84.2℃·month. Our results provide basic data on vascular plants and valuable information on elevational distribution ranges of current plant species in the Gakho mountain, which could serve as a baseline for comparison of the shifts in elevation under future climate change.
