In the present study was surveyed the flora, vegetation structure, growing environment, and soil characteristics in the wild habitats of Vaccinium oldhamii and offered basic information for habitat conservation and restoration. Most of the wild habitats of V. oldhamii were located at altitudes between 5 and 1095 m with inclinations of 2-33 , Dense populations were found around the climbing routes of the north-facing mountain slopes and dry rocky areas along mountain ridges. Vascular plants identified in the surveyed V. oldhamii habitats (28 quadrats in 12 habitat areas) included 129 taxa (50 families, 94 genera, 115 species, 9 varieties, 2 subspecies and 3 forms), of which woody plants accounted for 31.1%. The flora identified in the habitat areas were classified into four community types: Community I (Pinus densiflora -Quercus mongolica), Community II (Pinus thunbergii), Community III (Pinus rigida), and Community IV (Castanea crenata). The differences among communities within V. oldhamii habitats were more dependent on the occurrence of species with high importance percentages than on the population sizes of the species observed. The soil characteristics of V. oldhamii habitats were as follows: mostly silty loams; well-drained; shallow available-soil depth; high acidity (pH 3.93-5.07, mean ¼ 4.63, lower than mean Korean forest soil pH of 5.5); and mean available phosphate (=9.485 mg/kg, lower than the mean Korean forest soil available phosphate of 26 mg/kg). Mean species diversity, evenness and dominance were calculated as 1.216, 0.954 and 0.046, respectively. ARTICLE HISTORY

-This study was carried out to survey the vascular plants on Mt. Seokbyeongsan (1,055 m) and provide a basis for the conservation and management of plant resources. The vascular plants were surveyed from March to October 2015. The flora on Mt. Seokbyeongsan was classified as follows: 102 families, 295 genera, 454 species, 4 subspecies, 51 varieties, 7 forms, and a total of 516 taxa. Endemic plants included 17 families, 24 genera, 25 species, 1 variety, and a total of 26 taxa. The Korea Forest Service assignment of rare plants, including 21 families, 33 genera, 33 species, 3 varieties, and a total of 36 taxa, was investigated. Moreover, the Ministry of Environment assignment of rare plants, including 13 families, 17 genera, 17 species, 1 variety, and a total of 18 taxa, was investigated. Floristic special plants in the surveyed area were divided into five classes (Classes Ⅰ-Ⅴ): 42 taxa of Class Ⅰ, 26 taxa of Class Ⅱ, 35 taxa of Class Ⅲ, 20 taxa of Class Ⅳ, and 9 taxa of Class Ⅴ for a total of 132 taxa. Naturalized plants were 18 taxa, and plants threatened by climate change were 48 taxa. Key words -

We measured radial growth of Cryptomeria japonica and Chamaecyparis obtusa growing in Gangneung, Boseong, Yangsan and Ulleung-do, respectively and analyzed its relationship with temperature and precipitation. We found from the result of tree ring counting that forest stands of Cryptomeria japonica in Gangneung and Boseong was 40 to 50 years old and 50 to 70 years old in Yangsan and Ulleung-do. According to climate change, the mean temperature in Gangneung was found to be 12 o C to 13 o C which was similar to that of Boseong and Yangsan 40 to 50 years ago. While the result of the radial growth measured from Cryptomeria japonica in Gangneung showed a slightly decreasing tendency compared to the other areas, Chamaecyparis obtusa showed an increasing tendency. In the case of Cryptomeria japonica, a strong negative correlation between radial growth and climate related variables including both mean temperature and mean precipitation existed in Ulleung. There was a strong negative correlation between radial growth and mean temperature for Chamaecyparis obtusa in Yangsan, although there was a positive correlation in Gangneung and Yangsan.

In this study, we identified a variety of plants observed in the wetlands of Gangwon Province. We believe that this study will provide useful data for future research on the conservation and management of wetlands.

Investigation of flora was performed from March to October of 2008 as Eastern and Western coastal districts located in the same latitude (36°47′-37°48′), in order to apply this to basic data for effective protection and management of coastal forests also for insurance of biodiversity in coastal forests. As a result of the investigation of floras, both coastal forests recorded product-plants as follows: 98 families, 262 genera, 370 species, 46 varieties, 4 forms, 1 hybrid, 421 taxa in total. The Eastern coastal forests had 85 families, 188 genus, 248 species, 32 varieties, 3 forms, 1 hybrid, 285 taxa in total, whereas Western coastal forest had 96 families, 227 genus, 306 species, 39 varieties, 2 forms, 1 hybrid, 348 taxa in total. Among them, seashore plants accounted for 10.2% of total plants appeared in both coastal, and they are 26 families, 38 genus, 40 species, 3 hybrids and 43 taxa in total. There are special Korea plants in both coastal; 9 families, 9 genus, 8 species, 1 varieties, 1 hybrid, 10 taxa in total. There are rare plants in both coastal; 8 families, 8 genus, 7 species, 1 varieties, 8 taxa in total. Naturalized plants are also existed; 11 families, 24 species, 1 variety, 30 taxa in total.
