경기도 연인산의 자연환경 보전 방안

This investigation was performed to figure out the distribution of Korean endemic species, phytogeographically rare plants and endangered species, and invader species on Mt. Yeonin in Gyeonggo-do from August till October in 2016. The investigated vascular plants consist of total 246 taxa: 4 forms, 23 varieties, 236 species, 141 genera, 64 families. Among them there are 12 taxa of Korean endemic species, 2 taxa of V grade and 10 taxa of Ⅳ grade of phytogeographically rare plants, and 2 taxa of II grade of endangered species. So it is seriously needed to conserve their habitats and to get rid of some invader species especially Ambrosia artemisifolia var. dlatior Descourtils (Hogweed) Ambrosia trifida L. (Maple leaf hogweed) those are spread rapidly along paths and streams.
