This study has been carried out for the purpose of predicting the potential habitat sites of invasive alien plants in the DMZ and providing the basic data for decision-making in managing the future DMZ natural environment. From 2007 to 2015, this study collected the data for the advent of Ambrosia trifida var. trifida through fieldwork around the DMZ area, and simulated the potential distribution area of Ambrosia trifida var. trifida using Maxent model among the models of species distributions. As a result, it showed that the potential distribution area of the Ambrosia trifida var. trifida was concentrated in the western DMZ with relatively low altitude and scanty in the central east regions with relatively high elevation and forest cover rate. Because the invasive alien vegetation is a significant threatening factor in the agriculture and restoration of ecology and it costs a lot to restore the area already invaded by invasive alien vegetation, advance precautions are necessary to prevent biological invasions. It is expected that it is possible to predict the disturbed ecosystems through this study for the efficient land use within DMZ in the future and to apply this study in setting up the areas for the development and conservation within the DMZ.

This study used high-resolution satellite images and supervised classification technique based on machine learning method in order to detect the areas affected by wildfires in the demilitarized zone (DMZ) where direct access is difficult. Sentinel-2 A/B was used for high-resolution satellite images. Land cover map was calculated based on the SVM supervised classification technique. In order to find the optimal combination to classify the DMZ wildfire damage area, supervised classification according to various kernel and band combinations in the SVM was performed and the accuracy was evaluated through the error matrix. Verification was performed by comparing the results of the wildfire detection based on satellite image and data by the wildfire statistical annual report in 2020 and 2021. Also, wildfire damage areas was detected for which there is no current data in 2022. This is to quickly determine reliable results.

In this study, we conducted a flora survey at Mt.Bakdal (363m) and Mt. Myeongbong (245.3m) in Paju-si, Gyeonggi-do. A total of 405 taxa, including 2 forms, 32 varieties, 8 subspecies, 363 species, 261 genera, and 87 families, were surveyed in the two mountain areas. The ferns were identified as 12 taxa from 6 families, the gymnosperms as 6 taxa from 2 families, the dicotyledonous plants as 290 taxa from 70 families, and the monocotyledonous plants as 97 taxa from 9 families. The remarkable plants included 8 taxa of the Korean endemic plants, which were Populus tomentiglandulosa, Salix koriyanagi, Clematis brachyura, Viola seoulensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, and Hemerocallis hakuunensis, and 3 taxa of the rare and endangered plants as designated by the Korea Forest Service, including Tylophora floribunda as Vulnerable (VU) species, and Viola albida and Chionanthus retusus as Least Concern (LC) species. The invasive alien plants were 35 taxa, including Rumex crispus, Phytolacca americana, Cerastium glomeratum, Chenopodium album, Chenopodium ficifolium, Lepidium virginicum, Amorpha fruticosa, Robinia pseudoacacia, and Trifolium repens, accounting for 8.5 percent of the 405 taxa of the surveyed plants. We intend to further identify plants through the studies on unsurveyed areas in the western part of the DMZ, identify the native habitats of rare and specialty plants, and use them as basic data for managing ecosystem-disturbing plants.

This study is to research the military remains of Korean War(1950~53) focused on Yeonchen, Cheorwon, and Hwacheon-gun in the central border of DMZ. The Yeoncheon-gun is installing 'Yeolsoe' and 'Taepung' observatory in the frontline battlefield adjacent to Southern Limit Line(SLL), and not only protects many military remains including war memorial and crematory facilities of UN troops, but also utilizes them as active educational places. The Cheorwon-gun is actively making known 'Baengmagoji memorial, 'Labor party office' and other buildings adjacent to 'Tourist security DMZ', but needs to set up many monuments around battlefields of 'Gimhwa' and 'Daeseongsan' adjacent to 'Eco-peace park DMZ'. With the battlefield of 'Paroho' as the center, which our troops made brilliant military gains during the war, the Hwacheon-gun protects and informs military remains such as '643 and 490 battlefields', 'Kkeomeok and Guman bridge'. Developing a network for military remains in connection with the annual local festivals, the experience tour and security will be available at these places.

Mt. Bonghwa reaches a height of 800 m (2,870 ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304 m (4,278 ft). It is important to survey the flora of Bonghwa-san in that it is a way to make out what kind of plant species exist in DMZ due to the geographical characteristics of Bonghwa-san adjacent to Korean DMZ. Therefore this study was conducted to elucidate the distribution of vascular plants and their value of Bonghwa-san. The vascular plants that were collected 10 times from May 2015 to April 2017 consisted of a total of 525 taxa; 93 families, 309genera, 458 species, 4 subspecies, 58 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 12 taxa including Echinosophora koreensis, Epimedium koreanum, Anemone koraiensis etc. Endemic species were 16 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica etc. 31 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.8% and 7.25%. Among the surveyed 525 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 213 taxa, 172 taxa, 196 taxa, 50 taxa, 23 taxa, 10 taxa, 6 taxa and 3 taxa, respectively.

The demilitarized zone (DMZ) covered about 1, 528 $\textrm{km}^2$ (length, 248 km; width, about 4 km), and the civilian control line (CCL) was established around the DMZ after the Korean War. The international organizations (UNESCO and IUCN) showed a continued interests on the biodiversity of the DMZ area, because of relatively well preserved environment and lack of anthropogenic disturbances other than agricultural practice (KFRI, 2000).

The De-militarized Zone(DMZ) on the Korean Peninsula is ecologically conserved and naturally developed as access to the area has been controlled in the past five decades. As a result, biodiversity and wetlands are developed very well, but they have not been sufficiently surveyed due to land mines and security reasons. Focusing on the Kyongui Line area in Paju DMZ, this study aims at examining the status of forested wetlands in detail through an on-site survey and understanding the features of forested wetlands in DMZ. The forested wetlands of Paju Kyongui Line area are inhabited by naturally grown Salix koreensis Andress. and Acer ginnale Maxim. and affected by Sacheon Basin region extensively. As the topography of this region is created of inundated area and gentle ground, it is easily affected by hydrology and irrigation and has ideal conditions as forested wetlands. In addition, forest wetlands in this area were used as agricultural land in the past but now transformed into palustrine forested wetlands after being deserted for long time. However, as construction of roads and railways increasingly blocks water paths, the coverage of Robinia pseudoacacia L. and Amorpha fruticosa L. is on the rise, which indicates that forestedwetlands are gradually becoming inland over time.

This study was conducted to identify the usage characteristics of the DMZ Punchbowl Trail (DPT) as a national forest trail (NFT) and to estimate its ripple effects on the local economy. The objective of this study is to provide policy implications for sustainable operational management. Out of the 500 questionnaires distributed, 215 respondents provided their complete travel itineraries and expenditures. The respondents, mainly aged 50 and above and residing in the Seoul Metropolitan Area, spend 3.5 hours of travel time to the DPT. Together with their families, the respondents typically spend approximately 4 hours for leisurely activities, primarily appreciation of scenic views and relaxation by visiting the "O-yubatgil." Furthermore, they extend their travels to other parts of Gangwon Province, where the DPT is situated. Within Gangwon Province, Yanggu County is the most visited destination. The respondents reported a notably higher average expenditure per visitor compared with the typical local walking tourists. Estimates show that the DPT generates an annual average of KRW 2.1 billion in direct expenditure (based on an average of 10,000 visitors for over five years), KRW 2.8 billion in production, and KRW 1.3 billion in added value, and it has created 40 jobs in Gangwon Province. The results of this study lies in empirically determining the specific economic scale and ripple effects of DPT as an NFT in the major sector, which occupies a significant portion of the Gangwon Province's local economy. The results will be instrumental in validating NFT policies and informing policy making for sustainable forest utilization.
