The Jeju Experimental Forests located in Jeju island ? the southernmost part of Korea, consist of Hannam, Seogwipo, and Gotjawal Experimental Forests. The forests started their history as experimental forests when the Hannam and the Seogwipo Experimental Forests were designated as national forests in 1922.
The forest is located on the southeastern side of Mt. Halla with an altitude of 300-750 m a.s.l.. The terrain in the forest is flat except the areas of Saryeoni orm(parasitic volcano, 524 m), geoinak (529 m) and maboonak (425 m). The forest holds the averaged annual precipitation of 3,000 mm and temperate, warm-temperate and subtropical climate patterns. The dominant trees in the forest are evergreen trees including Quercus acuta, Castanopsis sieboldii, Neolitsea acicularis and Daphniphyllum macropodum and deciduous trees such as Carpinus laxiflora, Quercus serrata and Styrax japonica. Some of plantations of Japanese cedar remains with a sporadic distribution.

The total area of Gotjawal, a lava forest, is 110 ㎢ accounting for 6% of the total land area(1,875 ㎢) of Jeju island. It is widely distributed in the eastwestern part of Jeju island and divided into four regions: Gujwa-Seongsan and Jocheon-Hamdeok regions in the east; and Hangyeong-Andeok and Aewol regions in the west. The Gotjawal not only retains a high degree of biodiversity and a unique ecosystem but also has been closely related to the life of local communities. Accordingly, it is considered as a natural heritage to be preserved. A total of 300 ha (2% of the total Gotjawal area) of Gotjawal have been designated as experimental forests by KFRI since 2011. The forest is located in the two Gotjawal regions, Jocheon-Hamdeok region(178.7 ha) and Hangyeong-Andeok region (121.1 ha)
