-This study was conducted to investigate the environmental characteristics of natural habitats, and the genetic variations in samples from 19 different quadrates of Asplenium scolopendrium 10 habitats. The natural habitats of A. scolopendrium were located at an altitudes 110-973 m with inclinations of 7-30°. All the quadrates were located on north facing slopes. The average field capacity of the soil is 31.4%, with organic matter at 16.7%, and the pH is 5.84. The soil texture was confirmed as sandy loam in 8 habitats and silt loam in 2 habitats. A total of 214 vascular plants were identified from 10 habitats. The importance value of the herbaceous layer (H) was the highest in A. scolopendrium, at 10.4%, followed by Arachniodes standishii (7.3%), Dryopteris crassirhizoma (6.5%), and Polystichum tripteron (5.3%), which implies that the natural habitats of A. scolopendrium are affinity with ferns. The species diversity of A. scolopendrium was estimated as on average 1.09, while the dominance and evenness were 0.12 and 0.87, respectively. The result of the RAPD analysis, among 59 bands amplified with a primer, 25 (42.4%) showed polymorphism. Twenty-one individuals of 10 habitats could be classified into four groups with similarity coefficient values ranging from 0.74 to 1.0. Mt. Mullae and Geumdaebong populations shows basal branching within the 21 individuals. Ulleung-do island and Jeju-do island population forms an independent clade, respectively. Mt. Moak and Byeonsan-bando clade formed a sister to the Ulleung-do island and Jeju-do island clade.

This study was carried out to investigate the flora of estuary regions, Namdaecheon, Jusucheon, and Maeupcheon, placed in the east coast of Gangwon-do. The vascular plants were summarized as 441 taxa, including 90 families, 277 genera, 388 species, 2 subspecies, 35 varieties, and 6 forms. Number of species in each investigated region was 271 taxa of Namdaecheon, 247 taxa of Jusucheon, and 285 taxa of Maeupcheon, respectively. Among the investigated 441 taxa, 7 Korean endemic, 5 rare plants and 37 specially designated plants by Ministry of Environment were also included. Aquatic and hydrophyte plants were collected 41 taxa, and the thinophyte and halophyte plants were investigated 22 taxa. The naturalized plants were 59 taxa, and the percent of naturalized plant species was estimated as 13.3%. Based on the floristic composition, Maeupcheon was estimated as well conserved estuary region among the investigated 3 rivers.

-This study was carried out to investigate the distribution and characteristics of plants resources in Mt. Jo-bong (Yangyang-gun, Gangwon-do) from April, 2011 to October, 2012. The vascular plants were summarized as 500 taxa; 92 families, 296 genera, 434 species, 6 subspecies, 49 varieties, and 11 forma. Among the investigated 500 taxa, 13 Korean endemic, 14 rare plants, 1 endangered and 75 specially designated plants by Ministry of Environment were included. The naturalized plants were 32 taxa and percent of naturalized plant species and urbanization index were estimated 6.4% and 10%, respectively.

-This study was carried out to classify the folk plants in inland of northern region of Gangwon-do. According to the survey results from 35 places of 9 counties and cities from April to October, 2010, the folk plants in inland of northern region of Gangwon-do consisted of a total 261 taxa; 73 families, 185 genera, 225 species, 2 subspecies, 30 varieties, and 4 form. Among the investigated 261 taxa, 3 Korean endemic, 11 rare plants and 9 naturalized plants were also included. The use by usage of 261 taxa was: 378 times; Edible, 53 times; Medicinal, 8 times; Dye, 7 times; Ornamental, 6 times; Fuel, 5 times; Spice, 3 times; Aroma, 2 times; Nectar, 41 times; Others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by whole plant and root. The consistency comparison between the scientific name and the local name were the highest in the 20's and the lowest in 80's.

-This study intended to investigate the distribution of natural habitats, and the environmental factors, vegetation and soil analysis at 22 different sites of 9 regions in order to understand the environmental characteristics of Adoxa moschatellina in Prov. Gangwon-do. Natural habitats are confirmed at 44 regions of 14 cities and counties except for Donghae-si, Sokcho-si, Gosung-gun and Yanggu-gun in Prov. Gangwon-do. Natural habitats were located at altitudes of 99-1,084 m with slope inclinations of 0-25°. A total of 215 vascular plant taxa are identified from 22 quadrates. Importance value for members of the herbaceous (H) layer were as follows: Adoxa moschatellina 32.8%; Meehania urticifolia 7.5%; Cardamine leucantha 5.1%; Scopolia japonica 3.8%; Corydalis remota 3.3%. The importance value of the last four species are high, so they are at affinity with Adoxa moschatellina in their habitats. Species diversity of investigated sites ranged 0.4870-0.9848, and that of evenness and dominance are 0.4525-0.7601 and 0.1335-0.4191, respectively. Cluster analysis based on importance value appeared the high relations with differences of dominance species. Field capacity of investigated sites ranged 4.29-38.45%, and the soil pH and organic matter were 4.61-5.98 and 2.44-20.21, respectively.
