Background: Baekdudaegan was designated in 2005 as a protected area to prevent destruction and conserve. However, there are many disturbed and destroyed areas. The total disturbed area amounts to $25.9km^2$ (0.94%), including $13.4km^2$ (0.49%) in the core area and $12.5km^2$ (0.45%) in the buffer area. This study aims to classify the vegetation types established in the disturbed areas and diagnose the current conditions for ecological restoration in the forest ecosystem. Methods: We surveyed the vegetation in the disturbed areas of Daegwallyeong and Chupungryeong and the surrounding natural areas. The survey conducted from July to September 2015 targeted a total of 54 quadrats by Braun-Blanquet method (Daegwallyeong, 22; Chupungryeong, 32). We also investigated the height and coverage of each layer. We classified the vegetation types based on the field data and analyzed the ratio of life form and the exotic plants, species richness, and vegetation index (Hcl). The Normalized Difference Vegetation Index (NDVI) was calculated from rapideye satellite imagery in 2014 and 2015. Results: Vegetation types were classified into 11 groups according to the criteria that included successional sere or plantation at first, followed by developmental stage and origins. As a result of the analysis of the survey data, species richness, vegetation index (Hcl), ratio of tree plants, and the NDVI tended to increase, while the ratio of the exotic plants tended to decrease with the time since disturbance. These indicators had the classified values according to the vegetation types with time since the disturbance. Conclusions: These indicators can be effectively used to diagnose the conditions of the present vegetation in the disturbed area of the Baekdudaegan area. In addition, the NDVI might be effective for the diagnosis of the disturbed status instead of the human efforts based on the higher spatial resolution of satellite imagery. Appropriate diagnosis of the disturbed forests in the Baekdudaegan area considering the established vegetation types is essential for the elaboration of restoration plans. In addition, restoration target and level should be different according to the disturbed status of restoration site.

This study examined the habitat status of wild birds at closed-trails and the control group of opened-trails in the national park of the Baekdudaegan mountains. After evaluating each area based on this, it's aimed at being utilized as basic data for future national park management and opening of trails. Upon field investigations and analyzing existing literary materials, it was found that there were a total of 76 bird species living around the trails. Among them, it was confirmed that 60 species can breeding and 10 species are protected by law. Upon assessing the scores of each area according to the evaluation standards of this study, Area I had 7 scores, area II had 13 scores, area III had 5 scores, and area IV had 16 scores, showing that the control group open-trail area IV between Jeongryeongchi and Seongsamjae had the highest score, and that area III of Wolyeongdae~Chotdaebong~Daeyasan~Miljae~Wolyeongdae had the lowest score. Evaluation of closed-trail according to wild bird species (Avifauna) was attempted in this study, but there were more bird species living in open-trails, while also having higher evaluation scores. Therefore, if opening trail is needed in the future due to excessive desires of visitors or inevitable social demands, it is judged that various environmental factors including mammals highly affected by people should be evaluated to open up the sector with the lowest score. Also, it is judged that through methods such as reservation systems, the number of visitors should be controlled or night-time hikes should be prohibited so that nocturnal wildlife can freely use the trails.

This study conducted a survey from April 2021 to December 2022 to investigate habitat factors affecting bird diversity in the region between Cheonwangbong Peak and Aghwibong in Baekdudaegan protected area, South Korea. Since the region has a spatial scale of 736.4 km² and is an area where a wide variety of habitats are mixed, we selected 20 survey areas of 3 km x 3 km by analysis of habitat homogeneity. As a result of analyzing the relationship between habitat environment and bird diversity in the survey area, it was found that the diversity of bird communities was directly or indirectly related to the diversity of terrestrial insects, slope, average habitat area, mean size of patches, elevation, and forest type, and distance from agricultural land. The slope of habitat, forest type, and distance from agricultural land affect the occurrence of food sources directly and indirectly, and the average area of habitats and forest type is closely related to the structural diversity of habitats. Therefore, it is determined that the diversity of bird communities is affected by the amount of food generated within the habitat and the diversity of habitats. It is determined that the relationship between bird communities and habitat environments in this surveyed region can be basic ecological data for establishing forest management measures to promote the diversity of bird communities.

On the basis of vegetation data collected by point-centered quarter method in analysis in Baekdudaegan of Gangwon province in the area of Hyangrobong, Odaesan, Seokbyeongsan, Dutasan, Deokhangsan and Hambaeksan, the study was carried out to classify forest communities and to evaluate the successional trends. The classification method of cluster analysis was used to make various disordered forests into several common groups for 1,004 sample points all together. By clustering the forests in the six study areas were classified into 28 forest communities, which were subjected to aggregate 8 representative forest communities on the count of species composition and species diversity. They were Mesophytic mixed forest community, others deciduous forest community, Quercus mongolica (dominant) community, Q. mongolica (pure) community, Pinus densiflora - Q. mongolica community, P. densiflora community, Betula ermanii community and Q. mongolica - Pinus koraiensis community. The ecological outlook from the result indicated that P. densiflora community and P. densiflora - Q. mongolica community, which were located in Seokbyeongsan, Dutasan and Deokhangsan around 1,000m above the sea level showed lower species diversity index. On the contrary Mesophytic mixed forest community, others deciduous forest community which was located in Hyangrobong, Odaesan and Hambaeksan mostly in protected area and national park around 1,500m above the sea level displayed higher species diversity index. As the composition ratio of Q. mongolica within a certain community was decreased, the species diversity was generally increased, assumed that abundance of Q. mongolica might be negatively associated with species diversity in the national deciduous forest.

The objective of this study was to understand the effects of soundscapes on forest landscape preference in the Baekdudaegan protected area. The study sites were selected in Jeombongsan and Sobaek National park selected within the Baekdudaegan. The landscape preference surveys were conducted by using landscape adjectives classified with Nature, Sound, Attractiveness, and Aesthetics. The comparative analyses examined the difference of preferences between only visual landscapes and visual landscapes with soundscapes. The research found out that soundscapes were associated with landscape characteristics, and positively correlated with the improvement in landscape preference. Thus, the research can infer that forest landscape assessment consider visual attributes as well as soundscape cues.
