This study was carried out to investigate flora of Mt. Dosol(Yanggu-gun, Gangwon-do). The vascular plants were summarized as 510 taxa, including 89 families, 281 genera, 438 species, 3 subspecies, 61 varieties and 8 forms. Among the investigated 510 taxa, 21 Korean endemic, 24 rare plants, 1 endangered plant and 122 specially designated plants by the Ministry of Environment were also included. The naturalized plants were 27 taxa. The percent of naturalized plants species and urbanization index were estimated as 5.3% and 8.4%, respectively. Usefulness of plants of 510 taxa listed consists of 201 taxa(39.4%) of edible plants, 186 taxa(36.5%) pasture plants, 144 taxa(28.2%) of medicinal plants, 56 taxa(11.0%) of ornamental plants, 16 taxa(3.1%) of timber plants, 8 taxa(1.6%) of miscellaneous plants and 4 taxa(0.8%) of fiber plants.

This study was carried out to investigate the vascular plants of Mt. Choejeong in Gachang-myeon, Daegu. From March 2017 to October 2018, a total of 22 studies were conducted. The vascular plants surveyed were grouped into 560 taxa, including 104 families, 297 genera, 495 species, 4 subspecies, 51 varieties and 10 forma. Endemic plants 15 taxa, Rare plants 5 taxa, Red list plants 5 taxa, Floristic regional indicator plants 54 taxa, Naturalized plants 36 taxa were recorded. Among surveyed 560 taxa, edible, medicinal, ornamental, timber, pasturing, industrial and fiber plants included 246 taxa (29.2%), 228 taxa (27.1%), 164 taxa (19.5%), 61 taxa (7.2%), 13 taxa (1.5%), and 8 taxa (0.9%). And because people are coming and going more frequently than in the past, this will result in more frequent influx of naturalized plants and a threat to the habitat of the plants that are currently growing.

High swampy land was formed to upper stream of Tumen river. It showed representative vegitation, like Carex sp., Scirpus radirans, Eriophorum latifolium. Wetlands plant and a dune plant were mixed in down stream area of Tumen river. On a dune, seashore plants, such as Carex kobomugi, Salsola collina, Raphanus sativus var. raphanistroides, Rosa rugosa, Scutellaria strigillosa, Linaria japonica, Phacelurus latifolius were appeared frequently.
