  • This paper aims to contribute to the introduction of forest certification (a private enterprise) in Korea by developing C&I with consideration of the Korean forestry situation. For this study, 6 attributes for establishing certification system at FMU level was applied. To weigh relative importance of international organization's assortment and indicators, AHP survey was conducted to each experts in political, ecological, social, and economic field. By the experts attending FSC's auditing process, indicators adopted through AHP survey were inspected again for the realistic application in the fields. In this process, the typical environment of Korean forestry in real aspect and problems in FSC system were reaffirmed. Therefore, 7 criteria, 27 indicators and 92 checklists were finally developed for the construction of forest certification based on the results of AHP surveys and from investigation on the realistic situation in the fields.

  • Fragmentation due to land developments causes disturbances and changes of composition in forest vegetation. The purpose of the study was to develop the impact assessment model for quantitative distance or degree of disturbance by land developments. This study conducted a survey about structure and composition of forest vegetation to determine degree of impact from land developments. The results of field survey, there was a difference in structure and composition of forest vegetation such as tree canopy, herbaceous cover, and number of vine and alien species the distances from edge to interior area such as 0m, 10m, 20m, 40m, and over 60m. To assess the disturbance of forest vegetation, the factors selected were the rate of vine's cover and appearance of alien species. The impact assessment model about vine species explained by a distance, forest patch size, type of forest fragmentation, and type of vegetation ($R^2$=0.44, p<0.001). The other model about alien species explained by a distance, type of forest fragmentation, type of vegetation, and width of road (85.9%, p<0.005). The models applied to Samsong housing development in Goyang-si, Gyunggi-do. The vines and alien species in the study area have had a substantial impact on forest vegetation from edge to 20 or 40m. The impact assessment models were high reliability for estimating impacts to land developments. The impact of forest vegetation by development activities could be minimized thorough the adoption of the models introduced at the stage of EIA.

  • The Environmental Conservation Value Assessment Map (ECVAM) is a five grade assessment map created with nationally integrated environmental information and environmental values. The map is made through the evaluation of 67 items, including greenbelt area and bio-diversity. The ECVAM assesses the stability of the community using forest maps. However, the existing assessment method is problematic because the assessment grades are evaluated using higher than practical values; in part because it uses even-valued overlay and minimal indicator methods. This study was performed in order to suggest an integrated assessment method that could complement the stability evaluation based on existing methods. Accordingly, this study added forest type information, including whether the forest was natural or artificial, to the overlay method using forest diameter maps and forest density maps. As a result, the proposed ECVAM indicated a drastic grade change. After applying the method in South Korea, Grade I areas decreased 12.1%, from 52.6% to 40.6%, Grade II areas increased 11.9%, from 17.4% to 29.2%, and Grade III areas increased 0.2%, from 17.1% to 17.4%, respectively. From the results of the field survey, we found differences between natural forest and planted forest with regard to the number of mortality, species of shrubs, and vine cover. This means that natural forests are more stable than planted forests. This study suggests an improved assessment methodology to complement the existing EVCAM method. The results are expected to be used in environmental evaluations and forest conservation value assessments in ecology and environmental fields.

  • The objective of this paper is to elicit some policy implications to promote agroforestry in South Korea from the consumers' perspective. We conducted internet survey to 640 urban households about the recognition of forest farming products. Consumers purchased forest farming products for their nutrition, medical function, and safety and regarded them as higher quality than crops cultivated from agricultural land. Consumers preferred forest farming products but revealed no difference in recognition of naturally-grown products. Consumers buying forest products prioritize the quality and medical function among attributes. Among consumers as their income increases, they regard naturally grown products more important than price and freshness. Therefore, to promote agroforestry in South Korea, certification for naturally-grown products to win the consumers' trust and the $6^{th}$ industrialization by combining experience and green tourism program must be considered.

  • Although many studies have been conducted on techniques and effects that can be applied to forest meditation in domestic forest healing meditation research, there has been little research on the space where forest meditation takes place. Nevertheless, a meditation space is not just a place concept but a forest environment element responsible for the healing function of a forest, i.e., a place containing healing factors, and can be an essential clue to the healing mechanism. Therefore, to determine whether a healing forest meditation space is suitable for meditation, this study selected the attribute items of the meditation space using the Delphi expert survey and then surveyed the user satisfaction of the healing forest meditation space using the IPA (Importance Performance Analysis) technique. The survey was conducted from August to November 2022, targeting 315 adults who used the forest meditation space at the National Center for Forest Therapy, the Saneum Healing Forest, and the Jathyanggi Pureunsup Arboretum in Gyeonggi Province. The result of the IPA analysis showed the average satisfaction with the forest meditation space was relatively high at 4.33 points on a 5-point Likert scale (4.33 points for the National Center for Forest Therapy, 4.34 points for the Saneum Healing Forest, and 4.37 points for the Jathyanggi Pureunsup Arboretum), indicating that the three healing forest meditation spaces were suitable for forest meditation. Satisfaction with the "Sounds of nature" was high in all three forests. On the other hand, all three forests showed a relatively low satisfaction with "Quietness," indicating it to be a priority problem to be addressed. Also, an open-ended questionnaire survey showed that the mediation space's natural elements, such as natural sounds, scenery, air, forest spaces, and scents, had a higher positive impact on meditation satisfaction than artificial elements, such as facilities. Therefore, it is essential to secure sound resources such as the sound of water and birds around the meditation space, and it is also necessary to consider ways to create a meditation forest in an independent area to avoid encounters with visitors and allow only participants in the forest healing meditation program to enter to increase satisfaction with forest meditation.

  • This study was conducted to investigate the influence of thinning and pruning on characteristics of forest stand, mesopore ratio and soil water content at the Pinus koraiensis stands in Gwangneung, Gyeonggido. The Pinus koraiensis had been planted in 1976 and thinning and pruning were carried out in 1996. A sample area survey was conducted at experimental plots (thinned and unthinned) in 1998 and 2005, and mesopore ratio and soil water content have been monitored from 2000 to present. Average tree height of the thinned plot increased from 10.9m to 13.2m and from 10.3m to 12.8m for the unthinned plot. Average D.B.H of the thinned plot increased from 15.9cm to 21.1cm and from 14.5cm to 16.7cm for the unthinned plot during the period 1998-2005. Crown density at the thinned plot increased from 81.5% to 95.0% and from 89.5% to 95.0% for the unthinned plot during the period 1998-2005. Mesopore ratio (pF2.7) of A layer soil at the thinned plot was 40.1% while that of the unthinned plot was 37.3%. Changes of mesopore ratio at unthinned plot were not associated with stand age, but those at thinned plot had increased and then decreased, showing declining of the practice effect. Average soil water content at the thinned plot were 23.7% and 22.4% for the unthinned plot. Soil watercontents at both plots have been increased with increase in stand age. But the difference of soil watercontent at each plot has been decreased, especially at the depth of 10cm.

  • The purpose of this study is to establish a linkage between local forest human resources policies and the analysis of forest resource conditions in Gyeongsangbuk-do. In particular, the study aims to gather insights from students enrolled local formal education institutions through a demand survey and their opinions. These findings would serve as basic data for the formulation of medium- and long-term policies. According to the results of the analysis, all surveyed groups expressed a desire to pursue careers, entrepreneurship, or further school education based on their forestry majors. Among, the most important needs identified for local human resources, receiving training related to field practice and access to information emerged as paramount. In addition, it was observed that educational programs were conducted on weekends and during school vacations, with integration into the school curriculum to ensure participants not only benefit from self-development but also receive administrative support. A notable observation in the survey results was the absence of a network among forest professionals, signifying a key weakness within the forest sector in Gyeongsangbuk-do. The results of this study hold significant value in terms of analyzing and sharing the educational preferences of forest human resources in Gyeongsangbuk-do, thereby serving as basic research data for proposing policies. In the future, by expanding the scope to include case studies and forest human resource preference analyses through cooperation with other local governments and institutions, the research can contribute to the establishment of national-level policies for forest human resources on a broader scale.

  • This study examined the attitudes of the Korean forest policy interest groups toward the new environmental paradigm and resources management paradigm which were emerged in western societies. The 1st survey was conducted for five interest groups (forest owners, timber industries, members of the Korean Alpine Club, members of the Korean Natural Parks Association, forestry experts) in 1995, and the 2nd survey was conducted in 2006 for three interest groups (forest owners, members of the Forest for Life, members of the Baekdudaegan Preservation Society). The survey results show that there are significant differences in attitudes and beliefs toward the new environmental and resources management paradigms among groups. The environmental conservation groups such as the members of the Alpine Club, Nature Parks Association, Forest for Life, Baekdudaegan Preservation Society favor the NEP and NRMP more than those of traditional forestry related groups such as forest owners and timber industries. But, there are no significant attitudinal changes among forestry related groups. This research provides valuable insights into understanding the attitudinal positions of the interest groups toward forest resources management and policy formulation in Korea.

  • Gaining an understanding of bird communities in different habitat types is essential for the conservation of ecologically important habitats. Wetlands possess different types of habitats and provide an important environment for wintering waterbird communities. This study compares avian communities in five different habitat types in the Moeyungyi Wetland Wildlife Sanctuary (MWWS), Myanmar. From December 2014 to the first week of February in 2015, bird and habitat data were collected from representative areas of five habitat types (i.e., short grassland, tall grassland, lotus fields, open water areas, and rice fields) at MWWS. We established nine sampling plots in each habitat type, and used the point quadrat method to survey habitats and the point count method to survey birds in the habitats. Simple one-way analysis of variance (ANOVA) and post-hoc tests were used to determine differences between bird communities. We made 95 detections during 19 daily visits to each of the five habitat types. During the survey period, we recorded a total of 10,389 individuals belonging to 52 different bird species, based on 7-min observations at each of the 45 point count stations. Furthermore, we detected significant differences by habitat structure (i.e., vegetation coverage, height, and density; water depth; and plant species diversity) as well as bird communities (i.e., species richness, abundance, and diversity indices). In addition, the detailed analysis of 52 avian species revealed significant differences among 45 species with respect to the mean numbers of observed individuals in the survey habitats. The findings of this study revealed significant differences in the structure and composition of waterbird communities among the five assessed habitat types. Because natural marshes provide preferable habitats for a larger number and greater diversity of birds, relative to rice fields, natural marshes should be prioritized for conservation and restoration in Moeyungyi Wetland Wildlife Sanctuary.
