The flora of Baekseoksan was investigated from June to October, 2010. Vascular plants of investigated regions were composed of 90 families, 297 genera, 440 species, 4 subspecies, 57 varieties, and 12 forms, totally 513 taxa, and the Pteridophyta index (Pte-Q) was 1.41. Twelve taxa including endemic genus Hanabusaya among the 513 taxa were Korean endemic. Nineteen rare plants, one endangered plant and 77 specially designated plants by Ministry of Environment were also investigated. The naturalized plants were 21 taxa, and percent of naturalized plant species was 4.1%.
Geomorphological landscape of the border region in Gangwon province can be divided by coastal area in the east, mountainous area in the middle and east, and plain area in the west along DMZ (Demilitarized Zone). According to this landscape, various geomorphological units such as mountain landform, river landform, coastal landform and volcanic landform are surveyed. Because there are unique cultural, historical, and ecological heritages, the region has the potential for a global attraction. Therefore, the geopark as one of institutions of natural environment preservation in UNESCO is alternatives to the activated program for DMZ where has undergone a conflict of value between preservation and development, as well as to the preservation of geomorphological landscape in the border region.
This study was performed in order to grasp the developmental characteristics in cone and seed of Pinus densiflora stands, which is distributed on a slope in the south and the north of Mt. Acha. Comparing the size in cone after September that the maturity in cone is completed with the average size in 2006 and 2007, the southfacing slope was 32.6 mm in length and 17.8 mm in width. The north-facing slope was 31.2 mm in length and 18.5 mm in width. Thus, difference wasn't big. However, the period of reaching the average size(29.8mm) of north-facing slope in 2007 was June 26 in the south-facing slope, and September 19 in north-facing slope. Thus, south-facing slope was surveyed to be faster by over 2 and half months. The water content after September was higher in cone of the north-facing slope. Even the period of being required that the ovuliferous scale in cone is opened was surveyed to be longer in the north-facing slope. In the meantime, comparing the average size in seed after September with length, the south-facing slope was 4.06 mm. The north-facing slope was 4.08 mm. Thus, it was surveyed to be mutually similar. In case of the south-facing slope, the period of reaching this average size (4.06 mm) was July 3. On the other hand, the north-facing slope was surveyed to be August 6. Thus, the south-facing slope could be known to reach this size faster by about 1 month. As for the seed number per cone, the north-facing slope was a little larger with 16.9 compared to the south-facing slope with 14.8. Even the rate of filled seed was indicated to be 56.2% and 60.0%, respectively, for the south-facing slope and the north-facing slope. Thus, the north-facing slope was shown to be higher. As for the germination percent in the filled seed, the south-facing slope was 88.6%, thereby having been surveyed to be higher than the north-facing slope with 80.8%.
In order to understand the flora of Mt. Byungdoo, survey of vascular plants was conducted in 2010. It found that flora of Mt. Byoungdoo was consisted of 295 taxa, i.e., 218 species, four subspecies, 60 varieties, and 13 formae. Among them, Korean endemic species was 18 taxa. Also, the conservatory plants classified from fifth to first grade by Ministry of Environment were distributed 60 taxa in the Mt. Byungdoo. It is shown that this site is very high biodiversity in spite of small area relatively. The naturalized plants were found eighteen taxa. Eleutherococcus senticosus and Lilium cernuum, rare and endangered species, were confirmed from this survey. Therefore, it needs the conservation strategy for rare and endangered species.
Chuncheon according to the IPCC guideline, and they increased from 1,014,382 ton-CO2 in 2000 to 1,084,914 ton-CO2 in 2009. Using BAU scenario GHG emissions in 2020 was estimated to be 1,518,526 ton-CO2, which increase approximately 40% from those for 2009. Six reduction methods were applied in this study, including solar power generation, substitution of LED lights, individual and families' energy reduction efforts, cogeneration of incinerator, and expansion of natural gas line. Estimated total reduced GHG emission was 174,340 ton-CO2.
