Mulyeongari-oreum is a freshwater crater lake on top of an “oreum” (parasitic cone) around Halla Mountain on Jeju Island. The island has a total of 368 parasitic cones, of which 91% are scoria cones which are mostly composed of water-permeable basalt. Unlike other scoria cones, the Site retains a plentiful amount of water as weathering of the slopes has led to the accretion of less-permeable, fine-textured soils at the bottom of the crater. Although it is an isolated environment, the Site plays an important role in maintaining biodiversity, as it provides habitats for over 760 species of plants and animals. Among them are the globally vulnerable fairy pitta Pitta nympha and some nationally threatened species such as the nationally endangered golden eagle Aquila chrysaetos and peregrine falcon Falco peregrinus; and the nationally vulnerable cinereous vulture Aegypius monachus and boreal digging frog Kaloula borealis. It also provides habitat to the Jeju striped field mouse Apodemus chejuensis, which is found only on Jeju Island. The Site is also known as “Su-ryeong-ak” or “Suyeongak” which means a hill with holy water.
