Objectives: Stress hormone (cortisol) can be used to analyze psychological and physiological changes and healing effects before and after in blood and saliva. Here it is applied to scientifically validate the effects of the healthy forest experience in Deogyusan Mountain National Park. Methods: A healthy forest experience program was provided to college students (males and females) at Deogyusan National Park. Stress, hormones (cortisol), blood pressure, pulse, oxygen saturation and stress, anxiety, and depression were measured. This study was designed to objectively analyze the effects of stress hormones before and after. Results: Depression, stress, anxiety, and satisfaction with the forest experience program in Deogyusan National Park were very high in reliability in terms of Cronbach's Alpha: depression scored 0.910, stress 0.558, anxiety 0.934, program satisfaction 0.826, and program effectiveness 0.894. Conclusions: In this study, we utilized the Healthy Forest Experience Program and the 'Health and Medical Center Health Record Book' of the Health Forest Experience Program (Ministry of Environment's Environmental Education Certification Program). In the future, we will seek ways to utilize saliva since it is easier to collect than blood samples and apply the stress hormone cortisol as a saliva authentication program. In addition, by implementing ecological welfare programs in which nature and human beings coexist through systematic preservation and restoration, the national park management can utilize ecological, scenic and cultural services wisely. We expect to be able to provide exploration and welfare services.

This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

This study aimed to analyze characteristics of the seasonal habitat use of reintroduced Long-tailed Gorals (n=7) in Woraksan (mountain) National Park. We collected 10,721 goral coordinates in Woraksan (mountain) National Park via transmitters, and analyzed habitat use (e.g., aspect, distance from stream and road) from November 2006 to January 2013. Aspect use was southwest (22.6 %), and seasonal aspect use had a southwestern slope (in the spring, summer, and autumn). A northwestern aspect was detected in winter, but slope of $30^{\circ}{\sim}35^{\circ}$ (19.0 %) was used regardless of the season and mean elevation use was 500 m. Moreover, seasonal use was higher in the summer and lower in the winter and spring. The distance from the stream was mainly 50 m in 17.2 %, except in the winter (distance of 300 m), and it was within 50 m in the spring, summer, and autumn. The distance from the road was 100 m in 25.7 %, and seasonal use was within 100 m except for the winter. Thus, we examined significant differences in the habitat use of reintroduced gorals in Woraksan (mountain), and provide elementary data for habitat stabilization of Woraksan (mountain) National Park where goral restoration has advanced.

The Catba national park (20$\circ$42'-20$\circ$54'N, 106$\circ$54'-107$\circ$09'E), which is a representative protected area in northeast Vietnam, was first investigated in terms of phytosociology of the Zurich-Montpellier School. 15 plant communities were identified from the seven vegetation types: Teetaria-Amoora gigantea community, Blechmum-Pitecellobium ferrugineum community, Impatiens-Dracaena cambodiana community, Rhizophora apiculata community, Avicenia marina community, Panicum repens community, Heterosmilax-Zanthoxylum nitidum community, Stachytarphyta jamaiensis-Bidens bipinnata community, microstegium vagans community, Dicranopteris linearis community, Randina-Sapium sebiferum community, Psidium gujava community, Elephantopus scaber community, and chirita aratformis community. Traditional pasturing and shifting agrie\culture by indigenous people in Catba national park were recognized as main disturbance regies, which have been far above sustainable levels. Ecological strategies for conservation and sustainable use on national park' ecosystem were proposed: (1) development of awareness program on sustainable life style of indigenous people, (2) establishment of multiple use module system of national park, (3) ecosystem monitoring of permanent ecological sites.

The indigenous fungi in Mudeungsan National Park were investigated between 2020 and 2022. All collected specimens were identified to the species level based on their morphological characteristics and rDNA sequences. Species belonging to the family Boletaceae were analyzed in depth. Six species, Aureoboletus sinobadius, Hourangia densisquamata, H. nigropunctata, Tengioboletus glutinosus, Tylopilus himalayanus, and Xerocomus subparvus were newly recorded as macromycota in Korea.
