국립 변산자연휴양림의 관속식물상에 관한 연구

Abstract

This study was conducted to provide basic data for the management, and gathering of eco-education resources while providing conservation and the utilization of plant resources in conjunction with a systematical investigation of the flora of Byeonsan recreational forest from July to November 2018. The numbers of flora were summarized as 271 taxa; 80 families, 197 genera, 243 species, 1 subspecies, 24 varieties and 3 forma, and the species/genus ratio and pteridophytes index were 1.38 and 0.18, respectively. The Korean endemic plants were 4 taxa including Populus tomentiglandulosa, Weigela subsessilis, Paulownia coreana and Aster koraiensis. The rare plants were 8 taxa; Prunus yedoensis, Illicium anisatum, Koelreuteria paniculata, Ilex cornuta, Mosla japonica, Belamcanda chinensis, and Pseudoraphis ukishiba. The naturalized plants were 29 taxa including Rumex crispus, Phytolacca americana, Cerastium glomeratum, and so forth. The naturalized plants that need to be monitored with consideration for the degree of naturalization and introduction time were Cerastium glomeratum, Ambrosia artemisiifolia, Aster pilosus, Bidens frondosa, B. pilosa, and Tagetes minuta. For the invasive alien plants, Aster pilosus and Ambrosia artemisiifolia, ecological characteristics and removal methods could be introduced to maximize the effectiveness of eco-education. The floristic regional indicator plants totaled 42 taxa; Prunus yedoensis in class Ⅴ, Wisteria floribunda and Pseudoraphis ukishiba in class Ⅳ, Illicium anisatum, Koelreuteria, paniculata, Callicarpa mollis and so forth in class Ⅲ, and Quercus glauca, Peucedanum japonicum, Caryopteris incana, Carpesium glossophyllum and so forth in class Ⅱ, and Thelypteris glanduligera, Castanopsis sieboldii etc. in class Ⅰ. The evaluation score of the floristic regional indicator plants was 166. The target plants adaptable to climate change which have been identified in the Byeonsan recreational forest were 11 taxa; specifically 3 northern plants and 8 southern plants. These plants should be used as eco-educational resources and also be included in the monitoring field to prepare management plans for potential climate change.
