  • This study was conducted to offer preliminary data for forest management from March and December 2011. Based on the number of standing trees by DBH classes, it is recommended to practice thinning and pruning to change the current young stand to mature stand. In Livelihood Environment Forest Protected Areas, young (0-10 years or 0-10 cm DBH) and detected trees need to be removed and selected healthy trees need to be heavily tended. Also, selected trees in age 20-30 (20-30 cm DBH class) need to receive concentrated tending. Since Livelihood Environment Forest Protected Areas had been vulnerable for erosion, the diversity of understory layer is low. In order to diversify deciduous trees, it is recommended to introduce new species and thin and prune existing trees. It is not proper to adapt clear cutting in a short time and should be partially regenerated using shelter-wood method or proper tending practices to the Pinus rigida dominanted forest. Tending existing under-story species including Quercus alina, Quercus variabilis, and Quercus serrata would be important.

  • For conservation of biodiversity, we designate and manage the major areas that are habitats of organisms as ecosystem protected areas. It is necessary to evaluate the biodiversity of protected areas relatively in order to establish strategies to protect and secure the biodiversity of protected areas. In this study, we selected evaluation indicators by which we can compare objectively the biodiversity of protected areas corresponding to forest ecosystem, and applied them to Mt. Jiri and Mt. Bukhan National Parks. We reviewed literatures to select evaluation criteria. Frequently mentioned criteria and the structure of the forest which plays an importantrole of forest biodiversity were selected as the evaluation criteria. As the result, the selected evaluation indicators were 7-species diversity, species richness, evenness, rarity, disturbance species, indigenous species, and forest structure. In Mt. Jiri and Mt. Bukhan National Parks, species diversity were 3.492 and 2.943, species richness were 8.998 and 9.793, evenness were 0.849 and 0.680,rarity were 11.976 and 10.783, and disturbance species index were 0.214 and 0.357 respectively. Both national parks had abundant indigenous species and showed various forest physiognomies and stable 4-layer structure. It was found that crown density was higher in Mt. Jiri. Most indicators were implied high biodiversity in Mt. Jiri and Mt. Bukhan national parks.

  • The Jeongmaeks are Korea's unique forest space recognition system that diverged from the Baekdudaegan. The Jeongmaeks are easily exposed to pressure because it is adjacent to the living area. Among them, Nakdong-Jeongmaek has high biodiversity, but damage is accelerating. According to the Convention on Biological Diversity (CBD) in 2022, the target is to expand the area of terrestrial and marine protected areas to 30% of national territory by 2030. As of September 2023, the area of terrestrial protected areas in South Korea is only 16.97% of the country's territory. This is due in part to the high proportion of private forests in the region, which makes it difficult to establish protected areas. Therefore, there is a need to establish Other Effective Area-based Conservation Measure (OECMs), which pursue complex and effective conservation that considers multiple values, as an alternative to protected areas. This study aims to identify areas suitable for OECM and to provide opinions on the establishment of appropriate management plans for each value using SOM and InVEST Habitat Quality model. This study evaluated the habitat quality of 206 villages located within 1km of the Nakdong-Jeongmaek and compared the characteristics of villages classified by SOM. As a result, the habitat quality was 0.867 for Tourism village (ClusterIV), 0.838 for Conservation village (ClusterVI), 0.835 for Mixed village (ClusterI), 0.796 for Production (ClusterV), 0.731 for Rural village (ClusterIII) and 0.625 for Urban village (ClusterII). When the distribution was identified through statistical analysis, the Kruskal-Wallis test showed that the distributions were not identical, with a p-value of 1.53e-08. Dunn's test showed a difference between Tourism, Conservation and Rural, Urban village. However, Mixed village was overestimated due to the lack of villages and the small area included in the study area. Moreover, Conservation village was somewhat under-evaluated in the analysis due to the use of a single weight for protected areas. It is necessary to perform additional reinforcement of the value evaluation of Jeongmaeks by conducting Forest Resource Survey and the National Natural Environment Survey. Therefore, we believe that sufficient validity for the establishment of OECMs in the Nakdong-Jeongmaek can be provided by addressing these limitations and conducting additional research.

  • Philippine fisheries code of 1998 (Republic Act 8550), which is enacted to achieve food security by managing, conserving and protecting fishery resources, obliges local governments to designate no less than 15% of jurisdictional municipal water as fisheries resource protection zone. Accordingly, Marine Protected Areas (MPAs) are the most extensively established as fisheries management and conservation tool and over 1,500 MPAs are reported in the Philippines. But there has been debate on the pros and cons of implementing MPAs because of the positive and negative impacts on local communities and fishermen. A dichotomous-choice contingent-valuation survey was conducted in the two municipalities of Guimaras, Philippines to investigate public opinion in debates over MPAs and to estimate willingness to pay (WTP) for MPAs to protect and conserve marine habitats for fishery resources. For the benefits and costs of MPAs, 43.6% of respondents thought the costs would be larger than the benefit, but 91% respondents voted in favor of increasing MPAs for fisheries resources as a protective measure. Finally, the estimated Turnbull lower-bound mean WTP (36.75ha) was php 493.6(US$ 11.3) per household to establish the additional MPA (36.75ha) in their municipality waters.

  • Purpose: The study aimed to analyze the occurrence and transfer status of emergency patients at Incheon International Airport in Korea. Methods: This study design included 810 patients for eight years, from July 1, 2014 to June 31, 2022. The collected data were analyzed with SPSS statistics version 25.0. Results: For the demographics, 531 (65.6%) were males, 151 (19.5%) were in the highest age group (in their 50s), and 289 (35.9%) were foreigners. The most common place of occurrence was in protected areas in the passenger terminal, with 341 (42.1%) of cases occurring here. The time of arrival at the site (z=-3.444, p=.001), stay duration at the site (z=-8.145, p=. 001), and transfer time (z=-3.623, p=.000) were all significantly longer. Conclusion: It is necessary to consider a rapid emergency transportation plan, such as developing a system that simplifies immigration procedures when emergency patients move from protected areas to general areas. Moreover, in order to quickly respond to foreign emergency patients, detailed characteristics will need to be identified. Lastly, considering the long transfer time, an instructing doctor should accompany an ambulance and actively perform advanced resuscitation.

  • It is necessary to evaluate the location suitability of protected horticulture facilities to guide and/or to plan new protected horticulture facilities in rural areas. For objective and systematic evaluation of location suitability of protected horticulture, three different evaluation models were constructed based on grading, proportion, and analytic hierarchy process(AHP). The models were used to evaluated the suitability of protected horticulture in three selected regions; suburban, plain, and mountainous. The results showed that there were significant differences in evaluation results of each model among the three regions.

  • This study suggested a citizen science based model to enhance the efficacy of the managing invasive alien plants and examined whose applicability in 3 Wetland Protected Areas (Jangrok of Gwangju metropolitan city, Madongho of Goseong in South Gyeongsang Province, and Ungok of Gochang in North Jeolla Province). The process consists of (a) collecting citizen scientist including local residents of 3 protected areas and piling up information on the 4 species of invasive alien plants (Sicyos angulatus L., Solanum carolinense L., Ambrosia artemisiifolia L. and Solidago altissima L) in a information platform Ecological Information Bank (EcoBank) from September 18th to October 31th, (b) constructing distribution map containing the location and density (3 phases: individual-population-community) of target plants, (c) providing distribution map to Environment Agency and local government who is principal agent of managing invasive alien plants in 3 protected areas, and from whom (d) surveying applications of the distribution map and opinion for future supplement. As a result, citizen science based monitoring should be continued to complement the nationwide information for the field management of invasive alien plants with the expansion of target species (total 17 plants species that Ministry of Environment in South Korea designated) and period of monitoring in a year to increase the usability of surveyed information from citizen science. In the long run, effectiveness of the management of invasive alien species applied by citizen science should be reviewed including efficacy of field management process from citizen's participating in elimination project of invasive alien plants and time series distribution followed by the management of the species.

  • Marine protected Areas(MPAs) are specially designated zones of the sea that are designed to secure operation of ecosystem function and to restore marine ecosystem to the original state by excluding all detrimental human activities. MPAs have been proposed in many countries as means of realizing sustainable fisheries and recently MPAs are newly receiving attention as precautionary measure for global warming and climate change. The purpose of this paper is to examine the possibility of MPAs as fisheries management tools through a wide range of literature analysis and to suggest necessity of fisheries purpose of MPAs in Korea. Establishment of marine protected area can accompany various economic benefits such as restoration of marine environment, preservation of habitats, promotion of marine tourism and so on. Especially, a lot of case studies suggested that MPAs may bring out benefits to the fishing industry as a result of enhanced stocks. Fisheries benefits of MPAs on targeted species include increased abundance, increased mean individual size and age, increased reproductive output, enhanced recruitment inside and outside refuge, maintenance of genetic diversity of stocks, and enhanced fishery yields in adjacent fishing grounds, so called spill-over. MPAs for ecosystem conservation and protection of coastal wetland have been applied appropriately and effectively, however, the Korean MPAs system is still detective due to absence of fisheries purpose MPAs. Finally, suggestions for Korean MPAs can be summarized as following four recommendations; to establish number of small-scale MPAs rather than few large MPAs, to designate island and its surrounding areas as reserve, to consider MPA design with stock enhancement program, and to undertake co-management with Eochon-Gye, the traditional coastal community in Korea.

  • This mini review examines the habitat connectivity and effectiveness of Korean Marine Protected Areas (MPAs) in the Yellow Sea Large Marine Ecosystem (YSLME) region. We first reemphasize that the Korean region of the YSLME is a single ecosystem (ecoregion) given the biophysical distribution patterns. The MPAs within the YSLME contribute about 50% to the total MPAs in Korea, accounting for about 10% of the territorial sea waters of Korea and 20% of the waters of YSLME on the Korean side. By area, national parks account for nearly 45% of the MPAs, followed by the wetland protected areas at 25%, with other types of MPA comprising the remaining 30%. Large MPA (> 100 km2) is the dominant type of MPA, accounting for 90% of the total area. We find that MPAs in the region are connected physically and perhaps also genetically. However, the level of protection was found to be low, and a no-take zone is rarely implemented. In addition, interrupted freshwater discharge caused by river-mouth dams poses a major hindrance to the physical connectivity of the MPAs. Restoration of the river-mouth dams and strengthened regulation on MPAs, with further expansion of MPAs in line with the current development of post-2020 global biodiversity frameworks, should be priorities for better management of marine resources. The newly revised law incorporating the concept of "Marine Ecosystem Axis Management" would reinforce the processes, and their effectiveness together with overall management of MPAs in Korea should be evaluated by designing appropriate measurement tools.

  • The Tibetan Plateau is home to the only alpine crane species, the black-necked crane (Grus nigricollis). Conservation efforts are severely hampered by a lack of knowledge on the spatial distribution and breeding habitats of this species. The ecological niche modeling framework used to predict the spatial distribution of this species, based on the maximum entropy and occurrence record data, allowed us to generate a species-specific spatial distribution map in Ladakh, Trans-Himalaya, India. The model was created by assimilating species occurrence data from 486 geographical sites with 24 topographic and bioclimatic variables. Fourteen variables helped forecast the distribution of black-necked cranes by 96.2%. The area under the curve score for the model training data was high (0.98), indicating the accuracy and predictive performance of the model. Of the total study area, the areas with high and moderate habitat suitability for black-necked cranes were anticipated to be 8,156 km2 and 6,759 km2, respectively. The area with high habitat suitability within the protected areas was 5,335 km2. The spatial distribution predicted using our model showed that the majority of speculated conservation areas bordered the existing protected areas of the Changthang Wildlife Sanctuary. Hence, we believe, that by increasing the current study area, we can account for these gaps in conservation areas, more effectively.
