This study was conducted to supply basic data for restoration and management of forests in Civilian Control Zone, with surveying naturalized plants around abandoned military camps. The total study sites are 72 abandoned military camps, from Gosung in east region to Paju in west region of Civilian Control Zone. The naturalized index of total area is 12.6%, and naturalized index of east and middle regions are 12.1% and 8.4%. But its index of west region is 15.9%. These results are due to geographical characteristics. The east and middle regions are in steep mountainous districts, and so but west region is flat district, and so naturalized plants was imported by only army. But west region is in flat districts, and so imported method of naturalized plants is very various. The main naturalized plants are Ambrosia trifida and Ambrosia artemisiifolia var. elatior in Civilian Control Zone. The main dispersion pattern of naturalized plants are gravity dispersion pattern ($D_4$) and wind and water dispersion pattern ($D_1$). The all naturalized plants are photophilic plants in survey sites. And so, if abandoned military camps are recovered to forests, the naturalized plants are disappeared because of the change of sunlight condition. So it is necessary to manage and recover forests, even if that area is Civilian Control Zone.

We investigated the hydrological and geomorphological characteristics of small irrigation ponds in civilian control zone of Paju city in Korea. Among 85 small irrigation ponds, water level of 52 ponds changed seasonally and that of 33 was constant. Water sources of 12 ponds were surface water, 29 surface water and ground water, and 44 ground water. 4 ponds locate in the edges of forests, 33 in flat-lands, and 48 in valleys. Water in 45 ponds was exchanged with paddy fields and 40 ponds were isolated from paddy fields. Endangered or endemic species were inhabited in 26 ponds, which have ground water as water source and constant water level. Based on these characteristics, we suggested 4 types of small irrigation ponds: spring, water exchanging, stagnant/spring, stagnant water. This classification system will help ecosystem managers to investigate ponds systematically and manage them based on pond type.

This study aimed to understand current flora of Western Civilian Control Zone (CCZ) in Korea. Some areas that located at Paju-si and Yeoncheon-gun were selected as representative survey area (Jangdan-myeon, Deokjin mountain fortress, Ilwol peak of Mt. Seokbyeong, Imjinriver, Sunaecheon stream, Sewolcheon stream in Paju and Banjeong-ri in Yeoncheon). Through this survey, 461 vascular plant specimens were collected from April 2012 to September 2014, twice a month and from October 2014 to October 2018, once a month. These were finally classified into 96 families 305 genera 413 species 4 subspecies 41 varieties 6 forms totally 464 taxa. There are remarkable plants such as 6 taxa of Korean endemic species, 44 taxa of specified species on a floristics aspect, and 35 taxa of alien and naturalized plants (7.5%). Meanwhile, it has not been observed any endangered plant species during the activities in this area.

This study attempted to conduct the study from a macro perspective more specifically through the temporal and spatial analysis of Minbuk villages according to a change in a Civilian Control Line, such as a social and spatial distribution and a change of the existing Minbuk villages. To this end, this study conducted the spatial analysis for the change in the Minbuk villages according to the adjustment of the Civilian Control Line in time series by using a map of the Armistice Agreement Vol. 2, Google Earth, a digital cadastral map, an administrative district map, and the like are used as spatial data, and summarizing and constructing, as attribute data, a statistical yearbook, Ministry of Defense and Cheorwon-Gun notification data, a Land Use Regulation Information System, and cadastral map attribute information. After the enactment of the Military Facility Protection Act, the analysis was performed on a 20-year basis based on the 1976 statistical yearbook of which the Civilian Control Line was drawn. As a result, the total area of the Civilian Control Zone in Cheorwon from 1975 to 2015 decreased by 105.8 km², and 9 of 14 Minbuk villages were released and only 6 villages existed. The unoccupied villages were analyzed as 14 villages, 10 fewer than the existing surveyed or statistical villages. The movement of the Civilian Control Line to the north may disappear the unique characteristics of the Minbuk villages but should be done carefully as it is closely related to the lives of the current residents, and policies should be established in terms of sustainable development and conservation of the villages. This study is significant in conducting the temporal and spatial analysis, which is the basis of the Minbuk regions and the Minbuk villages, and may be used as basic data necessary for subsequent analysis study.

The Demilitarized Zone (DMZ) stretches two kilometers north and south from the Military Demarcation Line (MDL) of South and North Korea. This area was established as a weapons-free buffer zone when an armistice agreement was signed in 1953. However, there have been several very high-tension military standoffss over the past 65 years. On the South Korean side, civilian access to the Civilian Control Line (CCL) and beyond to the north has been restricted, and natural heritage has been well maintained. Natural heritage is defined as living things, their habitat and non-living things of the ecosystem which deserve to be protected. Research shows that a variety of flora and fauna, their habitat, marshes and geographical structures are found across the DMZ region. Although the DMZ region has not been such a good place for habitat conservation, we can say that this area may be the best location for restoration in terms of its variety of ecosystems and considerable land size. Restoration of course depends on future plans and management policies. This area, including the DMZ and the well-protected north of the CCL, will be the best habitat for endangered species of wild fauna and flora if we classify the various habitat types and create a habitat map. In doing this project, we need to include the estuary of the Han River and the lagoon (brackish water lake) of the East Sea coast. In addition, we must establish long-term plans for conservation and sustainable use and do international scientific research across the DMZ region in collaboration with scientists of South and North Korea and international experts. Mutual cooperation between the two Koreas for investigation and conservation efforts is paramount.

We examined whether an artificial levee constructed on prime amphibian habitat influences fragmentation. Four different sites on both sides of a levee in the Civilian Control Zone(CCZ) were probed. Sites 1 and 2 are rice paddies on one side of the levee, and Site 3 is the stream that locates in the same side. All the three sites have water conditions of seasonal variance. On the other side, Site 4 consists of rice paddies with a stable condition of water supply, irrigated through a canal. The research sites were frequented and the frog populations were closely monitored. The investigation identified five species. Pelophylax nigromaculatus was the most frequent (n=295), followed by Hyla japonica (n=220) and Glandirana rugosa (n=124). Three Bufo gargarizans and eight Rana coreana were also found. The amphibians, however, were found to relocate themselves according to water condition to rice paddies or stream only within one side of the levee. Despite having ample sources of water and foods, Site 4 lacked large populations of frogs, even when droughts came. Both the species dominance index and the richness index indicated a more favorable living condition of the one side of the levee (Sites 1 and 2) over the other.

To reveal the relationship between pond type and chemical water characteristics and wetland flora, we investigated 8 small irrigation ponds in CCZ, which represent 4 types of irrigation ponds. Cation and anion concentrations in water were low at spring type ponds and cation or anion concentrations were high at others. Especially, Kyeongeuisun pond, which is water exchanging type, had high cation and anion concentrations. This indicates that water source of this ponds is surface water. CCA showed that chemical water characteristics and wetland flora were reflected in pond types. However, water exchanging type ponds were not clustered in a group, which comes from the difference in water source and we suggest that water source should be an additional criteria to devide pond type of water exchanging.
