This study has been carried out with the purpose of coming up with suggestions for designation of domestic protection areas and improvement of their management through a comparative analysis of the systems of management of the protection areas in South Korea, Japan and China. Starting with the designation of natural reserves in 1962, South Korea has prepared legal systems for preserving ecosystems and biodiversity, while continuing to designate protected areas. As the state has so far monopolized the designation and management of all South Korean protection areas that take up 10.8% of its entire land area (as of Dec. 2011), with such persisting issues as multiple designations of one and the same area for protection, overlapping management authorities, and management of privately owned land in the protection areas. In Japan, which has protected area sizes and relevant legal systems similar to those in South Korea, the state provides the basic framework for management, while delegating most of the duties related to direct operation and management to specific municipalities. China, with an integrated administrative management of protected areas, has related government offices and municipalities responsible for the designation and management of individual protected areas. South Korea needs to provide a legally based support system that would further enhance the value of areal protection and contribute to the promotion of local economy and community.

Background and objective: If the Nelumbo nucifera spreads in a wetland at a high density, it can have considerable positive and negative ecological effects on habitats. For this reason, it is necessary to precisely investigate the impacts of its rapid proliferation. This study was conducted to propose the distribution and management of N. nucifera, which can cause the degradation of wildlife habitats due to the rapid spread of internal and external environmental factors that may affect the Junam wetland ecosystem. Methods: For the investigation and analysis of physical and ecological characteristics, factors of the abiotic environment such as general weather conditions, topography and water depth structure, and soil and water quality analysis, and bioenvironment characteristics such as changes in the N. nucifera community distribution were evaluated. To assess whether the differences in the soil depth and physicochemical characteristics between the N. nucifera community and the aquatic plant community are statistically significant, a One-way ANOVA was executed. Results: N. nucifera was presumably introduced in approximately 2007 and observed at a prevalence of only 0.8% in 2009, but had expanded to 11.1% in 2014. After that, the area was increased to 19.3% in 2015 and 40.0% in 2017, about twice that of the previous survey year. The rapid diffusion of an N. nucifera colony can have adverse effects on wildlife habitats and biodiversity at Junam Wetland. To solve these problems, four management methods can be proposed; water level management, mowing management, installation of posts and removal of lotus roots. Control of the N. nucifera community using these methods was judged to be suitable for cutting and water level management when considering expansion rate, water level variation, and wildlife habitat impacts. Conclusion: As the biotic and abiotic environmental factors are different for each wetland, it is necessary to determine the timing and method of management through a detailed investigation.

Biodiversity is plummeting worldwide, and the major causes of such decline include habitat degradation and climate change. While cities do contribute to the negative impact to the environment, they can also serve as strategic centres for conservation programs. Sites qualifying as biogeographic islands within metropolitan Seoul were studied for the occurrence of two hylid species: the endangered Hyla suweonensis and the abundant H. japonica. This study demonstrates that neither habitat diversity nor surface area, but solely the occurrence of aggregated rice paddies is a requisite for H. suweonensis, hypothetically due to its strict breeding requirements. On the contrary, H. japonica occurrence was not affected by any of these factors, and all types of habitats studied were adequate for this species. The presence of an endangered species within the boundaries of one of the most populated metropolises suggests a strong natural resilience, which should be enhanced with appropriate actions. We emphasize that the management plans therein can, and should, be used as the first step in the conservation of H. suweonensis in metropolitan Seoul.

서울과 같은 대도시의 농경지는 인간의 간섭이 끊임없이 이루어지는 준자연지역으로 생산성보다는 도시의 생물다양성보존 및 경관다양성을 통한 일반시민의 자연체험이라는 측면에서 관리.보호될 필요가 있다. 그러나 도시지역의 농경지는 개발용지로 토지이용이 전환되어 급속히 감소하고 있다. 본 연구에서는 서울시를 대상으로 농경지 패취의 시간변화에 따른 토지이용변화를 살펴보고 서울시 비오톱유형도에 근거한 농경지 패취를 분석하여 서울지역 농경지의 경관생태학적 구조와 특성을 파악하고, 이러한 분석결과를 토대로 생물다양성 증진을 위한 농경지 관리모델을 구상하는데 그 목적이 있다.

도시 근교에 입지한 담수호소는 다양한 생물이 서식하는 생물다양성의 보고이나, 무계획적인 이용의 증가로 수질오염과 식생훼손의 위험에 직면해 있다. 이에 본 연구는 사천시 두량저수지를 대상으로 담수호소의 생물다양성 유지와 이용의 조화를 추구하기 위한 관리방안을 제안하고자 동 식물 생태계의 정밀한 조사 분석 자료에 근거한 관리지역 설정 과정을 거쳐 생물다양성 증진을 위한 생태적인 관리방안을 제안하였다. 생태계 조사 분석 자료를 바탕으로 비오톱 유형 평가, 야생동물 서식처 평가, 보호종 출현 유무를 종합한 결과, 생태계 보전지역으로 설정된 지역은 층위 구조가 형성된 자연림과 생물서식의 기반을 제공하는 수면 및 습지, 서식처 다양성이 높은 주연부 지역이 보전가치가 있었다. 관리지역은 식생이 교란된 지역, 오염강도가 높은 상업지, 공업지 등과 낚시로 인해 훼손된 수변지역으로, 식생천이 유도, 관목식재 등의 식생관리와 오염물질관리 체계 구축을 통한 적극적인 관리가 시도되어야 할 것이다. 담수호소에 있어 수변식생과 산림식생 훼손은 생물다양성 및 수질에 직접적인 영향을 미치므로 보존지역과 이용지역을 명확하게 구분하고 이용지역 이외에는 엄정하게 복원 관리하여야 할 것이다.

배 유기재배 과수원에서 최근 문제되는 병해충 종류와 재배농가의 병해충 관리수준을 설문조사하고 조류, 양서류, 파충류, 설치류 등 척추동물의 생물다양성을 일반 화학농약 방제농가와 비교하고자 2010년에 포장조사를 수행하였다. 유기재배 과수원 총 22개소에서 설문조사와 포장조사를 한 결과, 유기재배 농가는 유기재배 병해충 관리자재로 석회황합제, 식물추출물 및 미생물 혼합물, 오일류 등을 선호하였으며, 주요 문제 병해충은 검은별무늬병, 붉은별무늬병, 깍지벌레류, 배나무면충, 배굴나방 등이었다. 유기자재 살포횟수는 병해 방제를 위해 9~10회, 해충 방제를 위해 5~6회 수준이었다. 유기재배 과수원이 관행재배에 비해 검은별무늬병 이병율과 이병도는 높았으나, 깍지벌레류 피해는 차이가 없었고 과중은 감소하였다. 양서류, 뱀, 설치류, 꿩 등은 관행재배와 유기재배 과수원 간에 차이를 확인할 수 없었으나, 멧비둘기의 경우 유기재배 과수원에서 개체수가 유의하게 많은 섭식활동을 하였다.

Background: Invasive plant species are considered a major threat to biodiversity, ecosystem functioning, and human wellbeing worldwide. Climatically suitable ranges for invasive plant species are expected to expand due to future climate change. The identification of current invasions and potential range expansion of invasive plant species is required to plan for the management of these species. Here, we predicted climatically suitable habitats for 11 invasive plant species and calculated the potential species richness and their range expansions in different provinces of the Republic of Korea (ROK) under current and future climate change scenarios (RCP 4.5 and RCP 8.5) using the maximum entropy (MaxEnt) modeling approach. Results: Based on the model predictions, areas of climatically suitable habitats for 90.9% of the invasive plant species are expected to retain current ecological niches and expand to include additional climatically suitable areas under future climate change scenarios. Species richness is predicted to be relatively high in the provinces of the western and southern regions (e.g., Jeollanam, Jeollabuk, and Chungcheongnam) under current climatic conditions. However, under future climates, richness in the provinces of the northern, eastern, and southeastern regions (e.g., Seoul, Incheon, Gyeonggi, Gyeongsangnam, Degue, Busan, and Ulsan) is estimated to increase up to 292%, 390.75%, and 468.06% by 2030, 2050, and 2080, respectively, compared with the current richness. Conclusions: Our study revealed that the rates of introduction and dispersion of invasive plant species from the western and southern coasts are relatively high and are expanding across the ROK through different modes of dispersion. The negative impacts on biodiversity, ecosystem dynamics, and economy caused by invasive plant species will be high if preventive and eradication measures are not employed immediately. Thus, this study will be helpful to policymakers for the management of invasive plant species and the conservation of biodiversity.
