This study was conducted to investigate bird community and to suggest a proper way how to manage and protect bird community in Tokyusan National Park. The survey was carried over 2 main trail districts by line transect method at 20, February and 22, July in 1993. The observed birds were belong to 5 orders 17 families 34 species, they also have Sparrow Hawk Accipiter nisus, Kestrel Falco tinunnculus(natural monument no. 323), White-backed Woodpecker Dendrocopos leucotos(R) and Japanese Waxwing Bombycilla japonica(R). It is estimated that grass region above 1,000m altitude provided breeding habitats for Gray-headed Bunting Emberiza fucata in summer and wintering habitats for Rosy Finch Leucosticte arctoa in winter, This shows that this region should be protected for inhabitation of these birds. Mujukucheontong valley of Tokyusan National Park, which had been a good habitat for valley-inhabituating birds before twenty years ago, has a lower species richness by increasing using density, and so this valley shoud be properly managed urgently.

A survey which was to find out visitor's behavior and their satisfaction on nature trails in Mt. Jiri National Park was conducted to provide basic information and management methods. According to the survey, major visitors were male with the age between 40 and 50, and the residents of Gyeongnam with relatively high academic background. The visitors had obtained information about natural trail mainly from other visitor, not from internet. The visitors were mainly composed of big group and family. The main purpose of visiting was to escape congested everyday in Yupyeong and Hadong district, and to enjoy mountain climbing in Jungsanri and Baekmudong district. Although there were differences among districts, most visitors were satisfied with natural interpretation program. About 40% were recognized optimum length of nature trails as 2km and less.

To identify the characteristics of the dropping habits and to provide improved methods for sign survey of Siberian flying squirrels Pteromys volans, an investigation was carried out in Jirisan National Park from April 2012 to May 2013. The latrines of study area were checked once a month and the characteristics of dropping behavior were camera trapped. The feces of Siberian flying squirrel were found on the point which tree forked, mostly from November to May. The squirrel actively presents in forked tree mainly on the September to April. The Siberian flying squirrel is found to be a typical nocturnal animal as it actively move between 6p.m. to 7a.m.. The study found that squirrel does feeding and dropping in the winter time on forked tree. On the point which tree forked could be a good place for the squirrel to hide from their predator when there is no leaf on the tree. Conducting the sign survey is advisable from November to May, as well as with the careful approach to the animals. As Siberian flying squirrel is an endangered species, adjusting the survey period is mandatory, especially when doing environmental impact assessment and a research on its dwelling areas.

The survey of user's satisfactory degree of location, plantings, facilities, operation, and management factors on national parks' camp sites was carried out. Many problems were analyzed and identified. This survey was for proposing the correct way to plan and draft for camping site after this. In addition to, the realization of environmental education through nature friendly recreation was aimed at. According to the result of the survey, the followings were suggested as necessities to improve the camp site. 1. Repair and replacement of insufficiently managed facilities should be aimed at. 2. Facilities for a handicapped person should be preferentially introduced. 3. Active management and publicity in low-demand season that practiced by developed countries should be carried out. Seasonal program for various age groups should be operated. 4. Surrounding tourist site, camp site, and trail should be organically connected by shuttle bus and other transports. A survey was carried out for the user satisfaction in the campsites of national parks. Based on this survey concerned with the location, planting, facilities, operation and management, the problems were identified and analysed to improve future design and plan of the campsites. This study aims for the realization of environmental education through nature friendly recreation. The following points are suggested as needed according to the survey result. 1. damaged facilities should be repaired or replaced. 2. introduction of the facilities for disabled should be prioritized. 3. consistent and active management and publicity work should be operated in the off-peak season. and the seasonal activity programs for the various age groups should be provided. 4. the site should be well connected with other surrounding campsites and tourist sites using the shuttle bus and other transport method.

The purpose of this study was to investigate the damage caused by rodents in the area around Seseokpyeongjeon in Jirisan National Park and identify suspected perpetrating species by analyzing rodent excrement found near the damaged trees. Damaged trees were surveyed regardless of species of trees in the exploration trail in the target site where visual observation was possible. Sequencing analysis of mitochondrial DNA Cyt-b was performed on rodent excrement around the damaged trees to identify the perpetrating species. A total of 52 trees were damaged by rodents, and they were all identified to be Korean Fir (Abies koreana) and were concentrated in places where Korean Fir formed communities with high density. A total of 40 Korean Fir over 1.5 meters high were surveyed, and only the affected branches, not the whole tree, were found to be withered in 39 of them. A total of 12 Korean Fir under 1.5 meters high were surveyed, and 7 of which were found to have been completely withered, indicating that relatively young trees were more vulnerable to withering. The genetic sequencing analysis of excrement confirmed that the species that perpetrated the Korean Fir was Craseomys regulus.

Ageratina altissima is an invasive plant species known to threaten native plant communities in Korea. A. altissima is thought to invade shady forests from disturbed open areas; however, uncertainty remains as to how shade and litter depth might affect establishment. A study of A. altissima distribution characteristics in areas adjacent to trails was undertaken at Mt. Umyeon in Seoul, Korea. Increasing densities of A. altissima were found to correlate with greater light availability and decreasing litter depth (p < 0.001) within 10 m distance from trail locations and on ridges rather than further within forests and valleys. The effects of soil moisture content, soil gravel content and soil pH on distribution were not found to be significant, suggesting that A. altissima is adaptable to a broad range of soil conditions. Results indicate that forest areas close to trails may be particularly susceptible place to A. altissima invasion, demonstrating the need to carefully consider implications for A. altissima expansion in trail management.

A national park is a place to conserve natural resources and visitors to experience nature, and thus, it is necessary to identify the noise distribution characteristic in the national park and preserve and restore the soundscape. However, most national parks in Korea are exposed to noise, leading to negative perceptions of the national park's soundscape and affecting the ecosystem. Many national parks in other countries have investigated the ecosystem impacts caused by noise and have performed various management to reduce the noise. However, in Korea, there is still a lack of awareness of the effect on the ecosystem, overlooking the need for soundscape management. Therefore, in this study, we developed a noise map of Mudeungsan National Park to investigate the quantitative impact of noise on visitors and the ecosystem. Also, we measured the trail's soundscape to describe a sound grade classification, and the soundscape of main spots in the park was recorded for a year and then analyzed. Finally, the sound resource distribution map was described, which can be used as preliminary data to determine the national park's sound distribution characteristics and manage the soundscape.

This study measured the present number of encounters and established the evaluation criterion for the allowable number of encounters in the Seoseokdae summit area (SSA) of Mudeungsan National Park to examine managerial conditions of the number of visitors to the Seoseokdae trail section (STS). Data were obtained from a questionnaire survey of 263 visitors to STS selected through convenient sampling during June 2019. The average number of encounters in SSA was 18.7. Most of the respondents (95.4%) encountered fewer than 30 other visitors. The average maximum number of simultaneous users (AMNSU, measured at 15-minute intervals) in SSA was 13.4 persons (range: 3~31 persons). The AMNSU by the hour was the highest with 21.0 persons at 13-14, followed by 19.8 persons at 11-12, 15.5 persons at 14-15, 15.3 persons at 12-13, 12.3 persons at 10-11, and 10.8 persons at 8-9. Acceptable encounter number (AEN) developed by long-question format (LQF) was 59.2 persons, and that by short-question format (SQF) was 55.1 persons. AEN of the respondents who preferred "near-nature experience" at 27.5 persons was fewer than those who preferred "resort/tourism area like experience" at 46.6 persons. The present number of encounters and AMNUS (range: 3~31 persons) in SSA were fewer than AENs derived from LQF (59.2 persons) and SQF (55.1 persons). Eighty-three percent of the respondents preferred "near-nature experience," while only 10.5% of the respondents preferred "resort/tourism area like experience." 78.4% of the respondents did not perceive that SSA was crowded. The absolute majority of the respondents (92.3%) answered higher personal AEN than the perceived encounter numbers (PEN). The gaps between the personal AEN and the PEN were negatively correlated with perceived crowding.

This study analyzes the geographic information system (GIS) and machine learning models to understand the relationship between the appearance of hibernation sites and habitats in order to systematically manage the habitat of Asiatic Black Bear(Ursus thibetanus ussuricus) inhabiting Jirisan National Park, South Korea. The most important environmental factors influencing the hibernation sites was found to be the inclination(41.4%), followed by altitude(20.4%), distance from the trail(10.9%), and age group(7.7%) in the order of their contribution. A comparison between the hibernation habitat and the normal habitat of Asiatic Black Bear indicated that the average altitude of the hibernation sites was 63m, whereas the average altitude of the normal habitat was approximately 400m. The average inclination was found to be $7^{\circ}$, and a preference for the steeper inclination of $12-43^{\circ}$ was also observed. The average distance of the hibernation site from the road was approximately 300m; the range of separation distance was found to be 1,300-2,400m. This was thought to be the result of a safer selection of winter hibernation site by preventing human contact and outside invasion. This study analyzes the habitat environmental factors for the selection of hibernation sites that prevent severe cold and other threats during the hibernation period in order to provide fundamental data for hibernation ecology and habitat management of Asiatic Black Bear.
