The study was conducted to develop ecological restoration method of damaged area in DMZ vicinities. As the material for the ecological restoration, forest soil and trees waste have been used. Forest soils were collected for experiments in Yanggu, Gangwon Province. Effect of ecological restoration was analyzed through germination experiment. Germination experiment was performed using 12 kinds of woody and herbaceous seeds. Woody and herbaceous seed germination in test pot was relatively evenly. Mixed material consisting of forest soil and trees waste seemed a possibility as the material for the restoration. The effects on seed germination were higher in the case of mixing more than 70% by volume ratio of local resources. Total number germinated individuals were different depending on the mixing ratio of soil sampling depth. Individual plants showed different trends depending on the experimental combination. Results of the woody seed germination were affected only in the soil sampling depth. Seed germination of herbaceous received a combined effect on soil sampling depth and mixing ratio.

To analyze the behavioral characteristics of Korea endangered species female gorals (n=6) during the period of birth, using GPS collar attached on their necks, we carried out this study in two areas (Seoraksan and Woraksan National park) from March 2007 to May 2014. According to our analysis there was a change in their home range during the period of birth. The home range of females (n=6) in MCP 95% was Spring ($1.00{\pm}1.00km^2$) > Autumn ($0.66{\pm}0.30km^2$) > Summer ($0.61{\pm}0.40km^2$) > Winter ($0.50{\pm}0.10km^2$) (F=4.198, p<0.05). In the monthly analysis, their home ranges were dramatically reduced in May, June and July. It showed a statistically significant difference (F=24.261, p<0.01). These gorals showing a drastic change in home ranges were identified as gorals having offspring individual and their home ranges were decreased. The average altitude was $615.77{\pm}173.508m$ and there was no significant difference in major change between parous and nonparous female gorals. Through this analysis, we expect that it can be applied to the goral management and restoration project considering the time of birth.

Many investigations have been conducted on the biological damage and environmental conditions necessary to preserve the Janggyeong Panjeon and Daejanggyeongpan (woodblocks). We performed a survey on the concentration and diversity of airborne fungi in the Janggyeong Panjeon and compared them with the results of a survey from 2012. The temperature of the Beopbojeon building was slightly lower, while the relative humidity was higher than those found at the Sudarajang building. The concentration of airborne fungi in the Beopbojeon was 1.44-fold that of the Sudarajang. It was confirmed that the concentration and diversity of airborne fungi in the Janggyeong Panjeon differed depending on the sampling site. In total, 23 fungal genera were identified from the air samples, and 11 fungal and 1 bacterial genera were identified from the surface of the woodblocks. Among these, only five types of fungi were commonly distributed in the indoor air and surface of the Daejanggyeongpan; however, 58.3% of the fungi identified on the surface of the woodblocks were not observed in the in the air samples. The surface-dwelling fungi may accumulate dust to form microbial communities over time.

This study was carried out to evaluate the restoration effect in the restored Yangjae stream and to draw up an adaptive management plan based on the results. As the result of evaluation on the restoration effect, the restored Yangjae stream was evaluated with low naturalness in both terms of the morphology of the stream and the composition and spatial distribution of vegetation. The diverse functional groups were introduced in the vegetation restoration, but the flooding regime, which is significant in the spatial distribution of riparian vegetation, were not correctly reflected. Exotic species or species that were not ecologically suitable for the location were introduced on the embankment and thus a measure to improve those problems is required. As the ecological principle was not reflected in the restoration plan, the stream was constructed as the double terrace structure. Therefore, the width of the waterway was narrowed further, and the waterfront was not designed to accommodate changes from flooding disturbance, making the micro-topography of the stream simpler and the naturalness lower. The adaptive management plan was prepared to improve those problems, and a plan for creating an ecological network was recommended to enhance the restoration effect.

In the recent years, the incidence of abandoned concrete roads have been increasing rapidly due to road improvements and facilities route construction, these abandoned expressway and unused roads are scattered throughout the country but the management system is not clear, they does not be an effectively managed because there is no maintenance cost. In response to these social concern and expectation, the Korea Expressway Corporation that is management authority of the expressway is developing policy initiatives and various projects to restore the closed road to ecological for eco-friendly projects of the existing expressway. And as part of these projects, Hwanggan IC unmanaged abandoned concrete roads restoration project was done and it was conducting monitoring for ecological restoration that is not one-off but sustainable. After test construction over seven years at the time, test construction of four ways enforced but the boundaries have become blurred over time. And Pinus koraiensis, Callicarpa dichotoma and Sorbaria stellipilla var. typica planted in the site are dominating, else Amorpha fruticosa and Indigofera pseudotinctoria sowed are dominating. Invasive species is that Robinia pseudoacacia was growing in the colony. Over monitoring result time, the vegetation was taking root and the ecosystem was being restore. But the disturbance of vegetation happens due to planting of tree species that doesn't fit in the restoration area and advent of ecosystem Disturbing Species. The study will be providing a basic data that identify change of plant environment by monitoring of the site and soil environment during June to November 2016 and secure an objective evaluation data by analyzing the effects of ecological restoration for revegetation test bed evaluation for ecological restoration of expressway in ecological restoration construction in later.

This study was intended to develop and suggest 'residents-driven and citizen-participatory restoration procedures' for degraded ecosystems in BaigDooDaeGahn. With some concerns of current engineering-focused restoration approach for damaged ecosystem, the proposed procedures were designed based on the analysis of several case studies on citizen participatory projects such as the Habitat Movement, the Taean tidal wetland restoration effort in Korea, and some historical and innovative cases in Japan and the United States. The suggested procedures were considered to be a dialectical spiral model which was consisted of two goal axis, six system elements, four developmental stages, and five restoration steps. The new system and procedures were applied to damaged farmland areas (about 0.3 ha) on the top of BaigDooDaeGahn, Kangneung city with participation of more than 100 local residents and a dozen of citizen from Seoul. Both high level of possibilities and some barriers for future extended application were identified and adopted for the final version of the proposed procedures for ecological restoration.

In Germany has a long history of ecological restoration and restoration management. At the beginning of the 1990s, the "Erfolgskontrolle" was used as an evaluation program after the restoration project and many exchanges of views took place. It is the time, in Korea, there is a need for a comprehensive evaluation program after the restoration project, as there is no evaluation method yet. At this time it may be the "Erfolgskontrolle" in Germany as a practical model for the Korean restoration management program. The purpose of this study is to identify the concept and character of the "Erfolgskontrolle" and to demonstrate the implication and potential of application, through the analysis of the implementation example of the revaluation of river revitalization. To achieve the goal was carried out theoretical and 3 exemplary revitalization research cases. And it was endeavored to deliver the German way of acting and the basic idea to Korea. For the restoration, the "precautionary principle" should be considered first, the upper legal regulation should not be violated. In order to apply "Erfolgskontrolle" in practice, the goal formulation should be clear and systematically evaluated. And through the collection of typified cases, the comprehensive and unified theory should be established, it is possible, thus the qualitative assessment of the restoration project.

It can be said that the revegetation technology in Japan was started in 1960's when Japan entered into the era of high-growth economy. In the beginning, the revegetation technology was mainly applied on the man made slopes, and with the time, the fields of the revegetation technology have been extended to the urban landscaping, ecosystem conservation, prevention of desertification and so on. With the progress of the revegetation technology and the expansion of its fields, new problems have occurred. In this paper, I introduced the history of The Japanese Society of Revegetation Technology and the present condition, and discussed about the problems of the revegetation technology in Japan.
