Dongbaekdongsan and 1100-highland wetlands are the natural inland wetlands of Jeju Island having a difference in the composition of vegetation, climate, and topographic condition. Avifauna and their fluctuation were investigated between each wetland from 2009-2018 within 2 year interval. In total 86 species belonging to 32 families were observed, among which Dongbaekdongsan only harbors 78 species, whereas 1100-highland wetland harbors 47 species. The number of species observed was maximum in the year 2012 and the minimum in the year 2015 in both the wetlands. Despite being the wetlands of natural importance they support more land birds (79%) compared to semi-aquatic (16%) and aquatic birds (5%). Of the total bird species recorded, Japanese night heron (Gorsachius goisagi), and fairy pitta (Pitta nympha) are considered globally threatened. As per the national category: 10 are considered as a natural monument and 11 as an endangered species. The presence of different residential and migratory birds represent these areas as suitable breeding, resting and feeding ground. Our study will be useful for understanding the importance of freshwater wetlands for the conservation of birds.

Wetlands of Dongbaekdongsan were classified into two types of pond and vernal pool. 11 plant communities are established there such as Nymphoides indica community, Sparganium stoloniferum Community, Persicaria hastato-auriculata community, Scirpus triangulatus community, Triadenum japonica community, Juncus papillosus community, Deinostema violacea community, Centipeda minima community, Apocynum sibiricum community, Isachne globosa community, and Ulmus parvifolia community. Nymphoides indica community is established in a pond located on the entrance of the Dongbaekdongsan and Persicaria hastatoauriculata community appears on edge of the pond. Sparganium stoloniferum community is formed in nearby pond with relatively shallow water and Persicaria hastatoauriculata community is established on margin of the pond. Vernal pools had been used for drinking water source and for livestock in some cases in the past. Scirpus triangulatus community is established in the most wet site as the center of the pools and Juncus papillosus community - Deinostema violacea community - Triadenum japonica community, and Apocynum sibiricum community appear in a concentric circle pattern as far away there. Ulmus parvifolia community is established in a dry vernal pool. This is the first study on vernal pool carried out in Korea. Therefore, most vegetation types are new ones different from existing studies on wetland. 동백동산 습지는 못과 한시적 못으로 구분되었다. 어리연꽃군락, 흑삼릉군락, 좁은잎미꾸리낚시군락, 송이고랭이군락, 물고추나물군락, 청비녀골풀군락, 진땅고추풀군락, 중대가리풀군락, 수궁초군락, 기장대풀군락 및 참느릅나무군락의 11개 식물군락이 성립해 있다. 어리연꽃 군락은 동백동산입구에 위치한 한 못에 성립해 있고 좁은잎미꾸리낚시군락은 그 못의 가장자리에 성립해 있다. 흑삼릉군락은 수심이 비교적 낮은 인근의 못에 성립해 있고 그 못의 가장자리에도 좁은잎미꾸리낚시군락이 성립해 있다. 한시적 못은 과거 식수원으로 사용되었고 일부에서는 가축의 물먹이공간으로도 사용되었다. 송이고랭이군락은 그 못의 중심으로서 가장 습한 곳에 성립하고 청비녀골풀군락-진땅고추풀군락-물고추나물군락 및 수궁초군락이 그곳으로부터 멀어짐에 따라 동심원 구조로 성립해 있다. 참느릅나무군락은 상대적으로 더 건조한 한시적 못에 성립해 있다. 본 연구는 한국에서 한시적 못에 대해 처음으로 이루어진 연구이다. 따라서 본 연구에서 밝혀진 대부분의 식생유형은 습지에 대한 기존의 연구와 다른 새로운 유형으로서 그 가치가 있다.

Before supplying underground water through a tubular well, irrigation facilities for surface water were used in the transition zone to mountain area of Jeju Island. This paper has examined the hydrogeomorphologic characteristics of irrigation facilities in Dongbaekdongsan such as distribution, structure, water source and water balance. There are ten facilities including two wells and eight reservoirs. The well was constructed in a collapsed hollow of lava flow and has a stair to scoop up water which originates from boundaries between lava flow units below two or three meters deep. By contrast, the reservoir was constructed on a lava flow abundant in a micro-relief by building a stone wall with a sluice to have surface water easily introduced into the reservoir. Since a lava flow, particularly pahoephoe, often produces an impermeable layer, depressions and collapsed hollows developed in the lava flow could become small wetlands largely maintained by rainfall and provide a base for constructing irrigation facilities. Surface water flows into four reservoirs through temporary channels in addition to direct rainfall. Water storage of Meonmulggak consists of direct rainfall of 60.8% and water flow of 39.2%. Heavy rainfall produces overflow and subsequent surface runoff from Meonmulggak which contains an annual water volume of 1,860 m3. The water balance of catchment area including Meonmulggak demonstrates that rainfall is partitioned into evapotranspiration of 31.4%, deep percolation of 67.8% and surface water runoff of 0.8%, respectively.

Background: This study was conducted from March 2011 to February 2013 in order to evaluate the ecosystem value by examining the organic carbon distribution and cycling in the Quercus glauca forest, evergreen oak community at Seonheul-Gotjawal, Jeju Island. Results: The amount of organic carbon distribution was 124.5 ton C ha− 1 in 2011 and 132.63 ton C ha− 1 in 2012 for aboveground biomass. And it was 31.13 ton C ha− 1 in 2011 and 33.16 ton C ha− 1 in 2012 for belowground biomass. In total, the amount of organic carbon distribution in plants was 155.63 and 165.79 ton C ha− 1 in 2011 and 2012, respectively. In 2011 and 2012 respectively, the amount of organic carbon distribution was 3.61 and 6. 39 ton C ha− 1 in the forest floor and it was 78.89 and 100.71 ton C ha− 1 in the soil. As shown, most carbon was distributed in plants. Overall, the amount of organic carbon distribution of the Q. glauca forest was 238. 13 ton C ha− 1 in 2011 and 272.89 ton C ha− 1 in 2012. In 2011, the amount of organic carbon fixed in plants through photosynthesis (NPP) was 14.22 ton C ha− 1 year− 1 and the amount of carbon emission of soil respiration was 16.77 ton C ha− 1 year− 1. The net ecosystem production (NEP) absorbed by the Q. glauca forest from the atmosphere was 5 ton C ha− 1 year− 1. Conclusions: The carbon storage value based on such organic carbon distribution was estimated about 23. 81 mil won ha− 1 in 2011 and 27.29 mil won ha− 1 in 2012, showing an annual increment of carbon storage value by 3. 48 mil won ha− 1. The carbon absorption value based on such NEP was estimated about 500,000 won ha− 1 year− 1
