Mt. Jirisan is located in the southern region of South Korea. It is largest in its size, second highest and dedicated as the first national park in South Korea. It is at the southern end of Backdudaegan mountain ranges. Mt. Jirisan site in Gurae County is located in the very vicinity of the national park and is the second KLTER(Korea Long Term Ecological Research) station by Ministry of Environment and National Institute of Ecology. The site suffered natural forest fire in 1999 and 2000 in a row that combusted vegetation about 13 and 7 hectares respectively. Since that time, some tree species were planted in some of the area. In 2010, the county designated the forest area of 155 ha including the KLTER site as the Gurae Ecoforest and has managed the forest for ecological stability. The area is composed of a variety of ecosystems like secondary pine forest as major vegetation, naturally rehabilitated area, thinning area, reforested area.

Mt. Jumbongsan site has housed the KLTER(Korea Long Term Ecological Research) station run by Ministry of Environment and National Institute of Ecology since 2004. Mt. Jumbongsan is located between Mt. Soraksan and Mt. Bangtaesan and stretches over Gangwon-do, Baekdudaegan in the Korean Peninsula. The well-preserved old-growth hardwood forest represents the vegetation of Mt. Jumbongsan within the core of Mt. Soraksan Biosphere Reserve designated by UNESCO in 1982. Qurecus mongolica and Lindera obtusiloba are the dominant species in the tree and shrub layer, respectively. Research equipment in the site consists of a flux tower, soil respiration measuring system and a V-notch weir. The flux tower is set for measuring the flow of CO2 and the photosynthesis rate and microclimate of the canopy layer in the area, and the soil respiration measurement system for studying correlation between the amount of CO2 from soil microbes and roots of plants and the soil temperature, and lastly the V-notch weir for measuring the portion material flow running through a mountain valley and hydrological studies. Altogether, we are conducting the study of interactions among various taxa using information produced from the equipment.

Mt Halla San is in Jeju Island, the only volcanic subtropical island, in South Korea. Every year the island is hit by several typhoons. It has shaped unique environmental characteristics and biodiversity. In addition the mountain is one of the most popular vacation sites with growing ecological concern.
