The results of the study of the rare and regional species of the Jirisan (Mt.) Korea National Park has reported 3 CR species, including the Allium victorialis var. platyphyllum, 4 EN species, including Rhododendron tschonoskii, 7 VU species, including Cacalia pseudo-taimingasa, 11 LC species, including Lilium distichum, and 3 DD species, including Aconitum chiisanense, which makes a total of 28 species. In terms of species exclusive to the region, a total of 7 species, including Fraxinus chiisanensis, Pseudostellaria heterophylla, Filipendula formosa and Cirsium chanroenicum, were confirmed, and since they were distributed widely in the Jeonji region of Jirisan (Mt.), there was minimal damage. Since rare species are localized in the region of Agosan (Mt.), there has been continuous damage due to visitors and hikers to the area, and there seems to be the need to handle the decreasing habitat for Allium victorialis var. platyphyllum, Juniperus chinensis var. sargentii and Trientalis europaea.
