The flora of the Chuwangsan National Park was surveyed. The field works was done for three times from February to October, 1994. The total number of vascular plants in this area were surveyed as 433 taxa ; 94 families, 260 genera, 365 species, 60 varieties, 2 subspecies, 5 formas, and 1 cultivars. The twenty seven taxa which were artificially planted could be found at the temple and abandoned cultivated areas. The population of Jeffersonia dubia Benth, one of the rare and endangered plants in Korea, were surveyed and mapped for an ecological monitorings in the future. Since this population is restrictly located in the vicinity of the mountain trails, the protection measures should be urgently needed in the future.

In this study, the faunae before and after creating the Solbangjuk Wetland Ecological Park located in Jecheon-city were compared. As a result, the change of the fauna according to the creation of the park showed the phenomenon that the species having the strong wilderness are reduced and the rate of general species become higher. In addition, the species which receive the restrictions for moving such as mammals, amphibians and reptiles are being gradually decreased by the increased visitors owing to the creation of the park. Moreover because there was the case where group of fishes have died caused by discharging and working the water in the reservoir during the creation process of the park, the supplementation work for this is required. However, it showed that the insects sucking the honey from flowers in the composed flower garden after creating the park, and the aquatic insects which live in this park that the stable water system for the growth of wetland plants is maintained, are increased, respectively. As a result of this survey, because the reservoir for agriculture adjacent to the residential area is generally small, the securing of the habitat space for the wild animals living in this park when creating the ecological parks seems to be necessary. The countermeasure should be considered so that some areas of the reservoir can be maintained in their natural state by adjusting the visitors' trails and the position of facilities for in order to secure the habitat of the wild animals.

Due to the effects of rapid changes in the living environment since 2000 and the recent unforeseen pandemic, people are refraining from domestic and international traveling and movement, and outdoor activities for health and the public value of forest trails, called Dullegil Trail in Korea, have become more important. This study estimated the environmental value of the tentatively named "East-West Trail," which connects the forest trails crossing Chungcheong and Gyeongsang Provinces using CVM (Contingent Valuation Method). It surveyed visitors to the East-West Trail, and 725 questionnaires were used for analysis. The average characteristics of respondents were those who exercised 2-3 times per week, visited a forest trail not far from their residence with friends or family, and showed a tendency to spend 50 thousand Korean won or more per visit. Visitors to the Dullegil Trail felt that there was a shortage of information boards on the forest trail, and they preferred a shelter in appropriate locations. We used a double-bounded dichotomous choice (BDDC) logit model proposed by Hanemann to measure the conservation value of the East-West Trail. It was estimated that the environmental value that a visitor to the East-West Trail could obtain was 30,087 won per trip. The estimated environmental value of the East-West Trail can be converted to about 94 billion won total visitors annually based on the population belonging to the direct-use zone near the East-West Trail. As there has been no study on the environmental value of forest trails using CVM, the results of this study will be able to suggest the feasibility of the government policies on forest trails.

In order to propose effective conservation management plan, this study verified ecological characteristics, humanities and Social characteristics. The research site is private property which is owned belonging to the Kim's of Gimhae that have long history. The study site is more than a thousand years old and was created for protecting from typhoon. There held the religious ritual what is called Dongsinje until 1960s. There have been protected and managed by the villagers. As the results of analysis, the area of windbreak are $12,392.69m^2$. The windbreak is dominated old years deciduous broad-leaved tree such as Zelkova serrata, Celtis sinensis, Aphananthe aspera. Around there were farmlands(52.1%), urbanized area(26.3%), forest area(16.6%). The vegetation communities of windbreak were classified by considering the dominant species and current status of forest. The forest types are following as; A. aspera community(I) which is using less pressure, Platycarya strobilacea-Carpinus coreana-Z. serrata community(II). Z. serrata community(III) which is using high pressure, Z. serrata-A. aspera community(IV), Z. serrata community(V) which is damaged under canopy trees. The windbreak was in good condition whereas, there were concerns the some wrong status was being undermined such as the wrong forest restoration projects in the past, the trails that is penetrating inside the forest, building up education facilities. Therefore, in order to restore the value of windbreak what is so called Suwol forest, we should improve the problems of forest ecosystem such as wrong management, forest fragmentation by facilities and decline in forest by lack of growing the next generation trees. In addition, we should remove excessive resting facilities and lead to passive use of forest. to improve the way of wrong management, moreover, we should close off he trails that is penetrating inside the forest for improving fragmentation. We should restore vegetation restoration and fostering the next generation trees for forest ecosystem. In order to restore unique of histo-cultural and ecological forest landscape, the next generation trees should be grown up that is the dominant species in Suwol forest. Moreover, as a results of comparing the between good vegetation communities and damaged vegetation communities, it is necessary to complementary planting for demeged vegetation communities, therefore there needs to 10.8 under canopy trees, 79.7 shrubs.

Major statutory nature protection areas include Nature Parks, Nature Reserves. Nature Ecological System Protected Areas. Biosphere Reserves, Nature Protected Forests, Wildlife Sanctuaries, and Protection Forests with total area of 1,124,000 ha. These protected areas cover almost 18% of the forested area. The number of visitors of NPs reached over 33 million per year with sharp increasing rate over the years. To protect the deteriorated hiking trails and camp grounds caused by overuse, two management policies have been implemented : cooking prohibition and natural rest rotation system. While prohibition of cooking is based on the fact that most of the solid wastes in nature parks are leftovers of cooking, natural rest rotation system is mainly for rehabilitation of deteriorated areas by natural processes. The system has closed 47 trails(in 27 mountains) throughout the country since January 1991, which is scheduled to continue 3 years. Due to the lack of accumulated scientific knowledge on how, when and where to close, application of the system leaves much to be desired. This paper discusses the current efforts to protect the natural resources for recreational use and suggests future directions for an effective policy implementation.

The objective of this study is to analyze the flora and forest vegetation of trails with high visitor density at Molundae. Nine quadrats of $20{\times}20m$ were selected for the survey. The survey was conducted from April to October 2010. The obtained results are summarized as follows. Plot1, plot2, plot3, plot4, plot6, and plot7 were located at slopes of $5{\sim}20^{\circ}$, 17~40m above sea level, and were formed with the colony of Japanese black pine(Pinus thunbergii Parl) and Japanese black pine(Pinus thunbergii Parl)-white oak(Quercus aliena Blume). Tree layer had the height of 8~20m, and the coverage of 50~70%, while subtree layer had the height of 3-8m, and the coverage 30~80%. On the other hand, shrub layer had the height of 2~4m, and the coverage of 10~30%, and herb had the height of 0.2~1m and coverage 5~20%. Plot5, plot8, and plot9 were located at the summit areas of 57~78m above sea level, and $0^{\circ}$ slope. Japanese black pine(Pinus thunbergii Parl) formed a community there. Tree layer was 8~20m high, and covered 60~70%, of the area, and subtree layer was 6~8m high, and coverage 30~40%. Shrub layer had the height of 2~6m, and the coverage of 30%, while herb layer had the height 0.2~2m, and the coverage 20-80%. Succession does not occur in the surveyed areas which have high visitor density. Artificially planted sawtooth oak(Quercus acutissima) trees were found to disturb succession and formation of multi-layer vegetation, resulting in the ecologically unstable forest. Therefore, the researcher suggested the strategy of managing the vegetation in the conclusion. This study has the limit in that the plots selected for the survey reflected only part of various trails in the Molundae area. It is necessary to suggest the vegetation management plans by selecting more diverse trail areas in consideration of the visitor density and behaviors, and analyzing the changes in vegetation quantitatively in order to manage the vegetation in urban areas damaged by visitors more effectively.

Increasing mountain biking (MTB) in forest recreation areas is changing the behavioral patterns in the areas where hiking has been a dominant activity, and it may cause ecological and social impacts to the areas. This study examined hikers' perceived conflicts by MTB including the relationship between socio-demographic and visiting characteristics and perceived conflict. On-site survey was conducted in Mudeungsan Provincial Park (MPP), Korea, during September, 2010. Out of 388 hikers participated in the survey, 374 responses were used for data analysis. 30.2% of the respondents encountered or saw MTB (avg.: 1.7 times) in MPP. Overall, 77.1% of respondents thought MTB in MPP was a problem. 73.5%~83.2% of respondents perceived conflict by four major MTB behaviors (e.g., too fast running MTB in trails; MTB bikes occupying trails; MTB bikes passing by hikers too closely; MTB bikers doing unpleasant behaviors to hikers). Based on the type of conflict, 48.5~62.4% of respondents fell in the type of "social values conflict (SVC)", 11.1~32.4%, "interpersonal conflict (IC)", and 16.8~26.6%, "no conflict (NC)", respectively. Types of conflicts were related with sociodemographic (e.g., gender, age, education) and visiting characteristics (e.g., number of visits, experience of encountering MTB). Such relationships were nonexistent in most cases when the "experience of encountering MTB" was controlled.

This study applied the theory of Landscape Ecology to representative resources of Jeju Olle-gil, which is a representative subject of walking tourism, to identify ecological characteristics and to establish a technique for landscape ecological analysis of Olle-gil resources. Jeju Olle Trail type based on the biotope type, major land use, vegetation status around Olle Trail and roads were divided into 12 types. Based on the type of ecological tourism resource classification, the Jeju Olle-gil walking tourism resource classification was divided into seven types of natural resources and seven types of humanities resources, and each resource was characterized by Geotope, Biotope, and Anthropopope, just like the landscape ecology system. Geotope resources are strong in landscape characteristics such as coast and beach, rocks, bedrocks, waterfalls, geology and Jusangjeolli Cliff, Oreum and craters, water resources, and landscape viewpoints. The Biotope resources showed strong ecological characteristics due to large tree and protected tree, Gotjawal, forest road and vegetation communities, biological habitat, vegetation landscape view point. Antropotope include Culture of Jeju Haenyeo and traditional culture, potting and lighthouses, experience facilities, temples and churches, military and beacon facilities, other historical and cultural facilities, and cultural landscape views. Jeju Olle Trail The representative resources for each type of Jeju Olle Trail are coastal, Oreum, Gotjawal, field and Stonewall Fencing farming land, Jeju Village and Stone wall of Jeju. In order to learn about the components and various functions of the resources representing the Olle Trail's ecological culture, the landscape ecological technique was interpreted. Looking at the ecological and cultural characteristics of coastal, the coast includes black basalt rocks, coastal vegetation, coastal grasslands, coastal rock vegetation, winter migratory birds and Jeju haenyeo. Oreum is a unique volcanic topography, which includes circular and oval mountain bodies, oreum vegetation, crater wetlands, the origin and legend of the name of Oreum, the legend of the name of Oreum, the culture of grazing horses, the use of military purposes, the object of folk belief, and the view from the summit. Gotjawal features rocky bumps, unique microclimate formation, Gotjawal vegetation, geographical names, the culture of charcoal being baked in the past, and bizarre shapes of trees and vines. Field walls include the structure and shape of field walls, field cultivation crops, field wall habitats, Jeju agricultural culture, and field walls. The village includes a stone wall and roof structure built from basalt, a pavilion at the entrance of the village, a yard and garden inside the house, a view of the lives of local people, and an alleyway view. These resources have slowly changed with the long lives of humans, and are now unique to Jeju Island. By providing contents specialized for each type of Olle Trail, tourists who walk on Olle will be able to experience the Olle Trail in depth as they learn the story of the resources, and will be able to increase the sustainable use and satisfaction of Jeju Olle Trail users.

The Sin-Wol filtration plant was an urban infrastructure and off-limits to the public. It is recreated as a representative experiential theme park in the southwest area. It has not only provided places to relax, but has made a new model of urban park by reusing advantages. The current lack of easy access into the park area almost isolates it like a green island. The neighborhood surrounding the park does not have many physical connections to the park to be able to use it. By connecting the surrounding communities with numerous access points into the park and linking the hiking trails and bike paths, the city's need for open space and recreation would be far better satisfied than before. This would allow for the use of the valuable assets of the existing forest and open space.

Oceanic islands are biologically important for their unique assemblages of species and high levels of endemism and are sensitive to environmental change because of their isolation and small species source pools. Habitat destruction caused by human landscape development is generally accepted as the main cause of extinction on islands, with exotic species invasion a secondary cause of extinction, especially on tropical islands. However, secondary impacts of human development (e.g., general degradation through resource use and exotic species introduction) are understudied on temperate islands. To determine secondary impacts of human development on the understory vegetation community, 90 field sites on Ulleung Island, South Korea, were sampled during the summer of 2016. Understory vegetation was chosen as it is a proxy for ecosystem health. Diversity and percent cover of introduced, native, and endemic species were tested against proximity to developed areas and trail usage using a model selection approach. Diversity was also tested against percent cover of three naturalized species commonly found in survey plots. The main finding was that distance to development, distance to town, and trail usage have limited negative impacts on the understory vegetation community within best-supported models predicting native and introduced cover and diversity. However, endemic species cover was significantly lower on high usage trails. While there are no apparent locally invasive plant species on the island at the time of this study, percent cover of Robinia pseudoacacia, a naturalized tree species, negatively correlated with plot diversity. These findings indicate that forests on Ulleung Island are not experiencing a noticeable invasion of understory vegetation, and conservation efforts can be best spent preventing future invasions.
