The GEF (37° 44" 39' N, 127° 9" 22' E) is a well-preserved forest located in the central temperate forest sub zone of Gyeonggi-do, Korea. It has been managed since the Joseon Dynasty, and public access to this area is currently controlled for the purpose of preserving the experimental forest. The long-term (1981-2010) annual mean temperature and precipitation of this site were 11.5 °C and 1438.2 mm. The dominant woody plants are Quercus serrata, Carpinus laxiflora, Quercus mongolica, Cornus controversa, and Pinus koraiensis in GEF. A multidisciplinary, collaborative research is being carried out at GEF. In addition, it was officially registered with the internal and external flux research networks (KoFlux, FluxNet, and AsiaFlux), and was therefore called Super Site.

Mt. Gyebangsan Forest (37° 44" 19' N, 128° 27" 11' E) is located in the border between Hongcheon and Pyeongchang in Gangwon-do, and belongs to a typical temperate northern cool temperature forest with lower average annual temperatures than the other regions. The long-term (1981-2010) annual mean temperature and precipitation were 10.3 °C and 1405.4 mm. The main dominant species were Quercus mongolica, Acer pseudosieboldianum, Tilia amurensis, Betula schmidtii, Pinus densiflora, and Kalopanax septemlobus.

The GMS (34°45′N, 127°59′E) is located in the southern coast of Gyeongsangnam-do, and belongs to warm-temperate forest zone. The long-term (1981–2010) annual mean temperature and precipitation were 14.1 °C and 1839.4 mm, respectively (Korea Meteorological Administration 2015). The dominant species are Q. serrata, Chamaecyparis obtusa, A. pseudosieboldianum, Carpinus tschonoskii, and Stewartia pseudocamellia. This area is originally a natural forest; however, it is adjacent to the C. obtusa plantation created in the past. Furthermore, it is possible to observe the expansion of C. obtusa through the natural regeneration of young trees.

The Wando Arboretum Forest (34° 31" N, 126° 75" E) was established in the Wando arboretum, Gunoe-myeon, Wando-gun, Jeollanam-do, Korea, and belongs to the warm-temperate forest region. The long-term (1981-2010) annual mean temperature and precipitation were 14.1 °C and 1532.7 mm. The dominance of the Quercus acuta is the highest, and the evergreen broad-leaved trees such as Castanopsis sieboldii, Machilus thunbergii, Neolitsea sericea, and Cinnamomum yabunikkei are mixed at a very high density. The value of Wando evergreen forests is considerably high because the temperate species in the southern temperate zone are attracting attention as an alternative to climate change adaptation.

The JJI (33° 18" 45' N, 126° 32" 31' E) belongs to a warm-temperate forest. However, Mt. Hallasan is the highest mountain in South Korea (1,950 m), and is surrounded by the sea. The long-term (1981-2010) annual mean temperature and precipitation were 16.6 °C and 1923 mm. The evergreen broad-leaved forests were found in the coastal area, sub-alpine species were found in the vicinity of the summit, and various habitats were found depending on the altitude. Unlike other survey sites, many evergreen broad-leaved species are growing in this site, but most of the forests, except for the highlands, have been severely damaged by the development of ranches and production of wood for mushroom cultivation. Therefore, the remaining evergreen broad-leaved forests are not large. Major species growing in these forests include Quercus acuta, Camellia japonica, and Carpinus laxiflora.

The Pyeongchang Model Forest (37° 48" N, 128° 52" E) was established in the Jungwangsan of Pyeongchang-gun, Gangwon-do, and belongs to the temperate north forest region. Because it is adjacent to the forest genetic resource protection area, the risks of damage and public access to this forest are considered relatively low. It comprises various species of trees such as Quercus mongolica, Acer mandshuricum, Acer pictum, and Cornus controversa.
