  • Due to rapid and reckless economic development, natural resources of the national land have been damaged and polluted. Accordingly, the necessity for environment-friendly development has been on the rise and many have made efforts to assess the environmental value of the national land. This study divides the conservation areas by means of using relative elevation, slope, and development of housing land based on environmental evaluation of the national land. The relative elevation is obtained by the difference of altitude at the edge of the forest patch extracted from the land cover classification map based on the ridgeline, and the slope is obtained by environment-oriented land suitability analysis. The development of housing land is classified in accordance with the progress of each project. Twenty-six evaluation criteria are divided into five different grades using the minimal indicator approach and then sub-divided into ten grades by means of using the following two scenarios. The first one uses the weight of input materials while the second one relies on the size of patches that are emphasized in landscape ecology. Consequently, such a study demonstrated the following results. The method relying on the weight of input materials revealed the limitation of emphasizing input materials excessively, whereas the method of considering the size of patches resulted in the division of conservation areas that embody regional characteristics. This study is meaningful in that it classifies the conservation areas by reflecting the regional characteristics and the ecological values of animals and plants.

  • The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

  • National parks and other protected areas often do not adequately protect national biodiversity because they were originally created for socio-economic and/or aesthetic values. The Korean government has committed to expanding the extent of protected areas to fulfill its commitments to the Aichi Biodiversity Convention. To do so, it is necessary to quantify the current levels of biodiversity representation within existing protected areas and to identify additional conservation needs for vulnerable species and ecological systems. In this study, we assess the proportion of species ranges found in South Korea's protected areas, for the species documented in the 3rd National Ecosystem Survey. We modeled the range distribution of 3,645 species in the following taxonomic groups; plants (1,545 species), mammals (35), birds (132), herptiles (35), and insects (1,898) using the MaxEnt species distribution model and calculated how much of each species' range is within protected areas. On average, 17.4% of plant species' ranges are represented in protected areas, while for mammals and insects an average 12.0% is currently conserved. Conservation representation for herptiles averages 9.3%, while it is 8.6% for birds. Although large proportions of species that have restricted distributions should be represented in protected areas, 17 plant species, two insects (Parnassius bremeri and Lasioglossum occidens), and one bird species (Phylloscopus inornatus) with ranges smaller than 1,000 ㎢ have less than 10% of their ranges within protected areas. Establishing specific conservation goals such as the protection of endangered species or vulnerable taxonomic groups will increase the efficiency of the biodiversity conservation strategies. In addition, lowland coastal areas are critical for biodiversity conservation because the protected areas in South Korea are mainly composed of high mountainous areas.

  • 인간의 개발로 점차 멸종위기 생물종이 증가하고 있어, 충분한 보호지역의 선제적 확보가 중요한 상황이다. 따라서 본 연구에서는 인간의 개발영향을 고려했을 때 앞으로 보호지역 선정 시 고려해야 할 보전 우선순위지역을 확인하였다. 보전 우선순위 도출은 보전계획 의사결정 지원 소프트웨어인 MARXAN을 이용하여 기존 보호지역 포함 여부와 개발영향 반영여부를 기준으로 총 네 가지의 시나리오로 분석하였다. 개발영향은 개발면적 비율, 인구밀도, 도로망 체계, 교통량을 이용하여 도출하였으며, 생물종 보전 대상 지역은 제 3차 전국자연환경조사 자료의 조류, 포유류, 양서파충류의 출현자료를 이용하여 도출한 서식적합지역을 이용하였다. 이 두 가지 요인을 입력 자료로 기계학습 기반 최적화방법론을 이용하여 보전 우선순위 지역을 도출하였다. 연구결과, 멸종위기 생물종을 보전하는데 중요한 역할을 할 것으로 기대되는 지역이 기존 보호지역과 떨어진 지역에서 다수 나타났으며, 개발영향을 고려했을 때는 보전우선순위 지역이 파편화되어 나타남을 알 수 있었다. 개발영향과 기존보호지역을 모두 고려했을 때에도 기존 보호지역 주변으로 이미 도로개발이 많이 이뤄져 기존 보호지역과는 떨어진 지역에서 우선순위가 높게 나타났다. 따라서 개발영향을 고려하여 멸종위기종 보호하기 위해서는 기존 보호지역 주변 이외의 지역도 검토해볼 필요가 있으며, 파편화되어 나타나는 보전 우선순위지역에 대한 대응방안 모색이 필요함을 알 수 있었다.

  • Although camera traps have been widely used to understand the abundance of wildlife in recent decades, the effort has been restricted to small sub-set of wildlife which can mark-and-recapture. The Random Encounter Model shows an alternative approach to estimate the absolute abundance from camera trap detection rate for any animals without the need for individual recognition. Our study aims to examine the feasibility and validity of the Random Encounter Model for the density estimation of endangered leopard cats (Prionailurus bengalensis) in Maekdo riparian park, Busan, South Korea. According to the model, the estimated leopard cat density was $1.76km^{-2}$ (CI 95%, 0.74-3.49), which indicated 2.46 leopard cats in $1.4km^2$ of our study area. This estimate was not statistically different from the previous leopard cat population count ($2.33{\pm}0.58$) in the same area. As follows, our research demonstrated the application and usefulness of the Random Encounter Model in density estimation of unmarked wildlife which helps to manage and protect the target species with a better understanding of their status.

  • The composition of the Martes flavigula diet has been extensively studied, but little is known about its insect component. This study characterized the insect diet and insect nest materials in the feces of M. flavigula. A total of 952 fecal samples were collected in Jirisan National Park from January 2009 to November 2011, and 1379 species or taxonomic groups were identified. M. flavigula fed on insects (8.7%) and bee wax (5.0%), which comprised 2.9% and 4.4% of the dry weight of M. flavigula feces, respectively. A total of 12 insect species belonging to 8 families in 3 orders were identified. The most frequently found insects were Hymenoptera (frequency of occurrence, FO, 89.1), including Vespa simillima simillima (FO, 37.3) and Vespula koreensis koreensis (FO, 20.0). The Vespidae constituted the majority of the insect diet in autumn when the diversity of marten's prey was strongly reduced, probably because the numbers of social insects were sufficient for M. flavigula. In addition, the data suggest that M. flavigula attacks the nests of social wasps in late autumn when males do not have a venomous sting and new queens are less aggressive than workers. Bee wax appeared in all seasons and the highest rate was from spring to early summer. However, the remains of honeybees were not found in feces; thus, M. flavigula presumably eats honey but not honeybees.

  • South Korea presently harbors less than 800 long-tailed gorals (Naemorhedus caudatus), an endangered species. I report for the first time on the taxonomic status and genetic diversity of the Korean species using non-invasive fecal sampling based on mitochondrial cytochrome b gene sequence analyses. To determine the taxonomic status of this species, I reconstructed a consensus neighbor-joining tree and generated a minimum spanning network combining haplotype sequences obtained from feces with a new goral-specific primer set developed using known sequences of the Korean goral and related species (e.g., Russian goral, Chinese goral, Himalayan goral, Japanese serow, etc.). I also examined the genetic diversity of this species. The Korean goral showed only three different haplotypes. The phylogenetic tree and parsimony haplotype network revealed a single cluster of Korean and Russian gorals, separate from related species. Generally, the Korean goral has a relatively low genetic diversity compared with that of other ungulate species (e.g., moose and red deer). I preliminarily showcased the application of non-invasive fecal sampling to the study of genetic characteristics, including the taxonomic status and genetic diversity of gorals, based on mitochondrial DNA. More phylogenetic studies are necessary to ensure the conservation of goral populations throughout South Korea.
