This study empirically examines the effectiveness of the Ramsar Wetland City Accreditation System in promoting integrated management of urban-adjacent wetlands, enhancing community participation, and strengthening local capacity. Using survey and monitoring data from Jeju-si, Inje-gun, and Changnyeonggun (accredited in 2018) and Gochang-gun and Seogwipo-si (accredited in 2022), the analysis integrates AHP and statistical verification to evaluate system effectiveness, operational elements, and the relationship between performance and perception. The results indicate that the system positively contributed to establishing a supportive social foundation, including improved information accessibility (72%), strengthened community capacity (71%), enhanced conservation and management interest (83%), and greater public understanding of wetlands (84%), which in turn led to increased program participation and behavioral changes. Trust in local governments and management committees was relatively high, reinforcing regional governance. However, limitations such as inconsistent and discontinuous implementation, declining trust in central government, overreliance on local government initiative, and budget imbalances across project types were identified as constraints to sustainability. To address these issues, this study suggests establishing a scientific performance management system, expanding financial independence based on local resources, strengthening the authority of local management committees, improving evaluation quality, enhancing central-local cooperation, ensuring balanced budget allocation, and advancing information feedback systems, thereby supporting the evolution of Ramsar Wetland Cities as models of sustainable socio-ecological development.

The 1100Goji Wetland and Sumunmurbamgdwie are designated wetland protected areas adjacent to each other within Hallasan, Jeju Island. This study aimed to identify the unique characteristics of these two wetlands by analyzing their geomorphological features and biodiversity. The analysis, which covered geomorphology and eight biological groups-including vegetation, flora, and fauna-revealed distinct geomorphological characteristics and significant differences in flora and entomofauna. Despite their close proximity within Hallasan, the vegetation, flora, fauna, and dominant species varied between the two sites depending on factors such as geomorphological traits and the surrounding habitat environment. Therefore, customized management strategies that consider the specific characteristics of each wetland must be established.

This study examined the feasibility to develop wetland OECMs in wetland inventory sites in South Korea. The study applied the National Institute of Forest Science & National Arboretum (2024) forest OECM evaluation criteria to the wetland inventory sites. Six of the seven criteria were deemed met. Furthermore, given the diverse stakeholders identified in the Criterion 7, efforts are needed to ensure fairness in governance and management. If these issues are addressed, an area of 660.99 km2 within the wetland inventory sites could be developed as wetland OECMs. This would significantly contribute to achieve the GBF target to designate 30% of the national land area as protected areas.

Citizen science has become an essential tool for ecological monitoring, however concerns remain regarding data reliability, particularly for taxa that require advanced identification skills. The present study evaluates detection accuracy and count reliability in citizen-based waterbird monitoring conducted at the Siheung Gaetgol Wetland, South Korea. The study analyzed a total of 27 citizen surveys and 7 expert-accompanied surveys collected from 2015 to 2019. We quantified (1) species-level detection rates, (2) the effect of citizen group size on species richness, and (3) relative count bias based on mean abundance per survey. The detection analyses revealed pronounced discrepancies for approximately one-third of species, particularly, and other visually challenging or crepuscular taxa, for which expert detection rates exceeded citizen rates by 0.2~0.5. Conversely, common and readily identifiable species exhibited no discernible variations. The number of species detected was found to be independent of the size of the citizen science group, with a range of 4 to 13 participants. This suggests that observer expertise, rather than survey effort, is a primary determinant in determining detection efficiency. The count bias indices further demonstrated a systematic overestimation of flocking species and underestimation of cryptic or small-bodied species. Despite the limitations of the study, which include unequal survey frequency and uncontrolled environmental conditions, the results consistently indicate that observer proficiency exerts a significant influence on both detection and abundance estimates. These findings underscore the necessity for targeted expert involvement, species-specific training, standardized counting roles, and routine data-quality assessments to enhance the reliability of citizen-based bird monitoring program.

This study explored the population dynamics of the endangered perennial plant Pterygopleurum neurophyllum (Maxim.) Kitag through a multi-year winter deadbiomass removal approach. In 2022, a total population census was conducted at Wondong Wetland (Yangsan, Korea), where seven spatially independent patches were identified (P-1 to P-7). From 2023 to 2025, winter dead-biomass removal was implemented in two of these patches (P-1 and P-2), while the remaining patches served as controls. Annual population counts were monitored, and the effects of winter dead-biomass removal over time were analyzed using a generalized linear mixed model (GLMM) with a Poisson distribution. The interaction between management and year was highly significant (Wald χ 2=103.93, p<0.001), indicating differing temporal trajectories between the removal and control populations. No significant management effect was observed in 2023; however, the removal plots demonstrated a dramatic increase in 2024 (EMMs: Control=5.05 vs. Removal=92.77), which continued in 2025 (3.89 vs. 104.99). These findings indicate that winter dead-biomass removal significantly promotes the population expansion of P. neurophyllum, with ecological responses emerging cumulatively rather than immediately. This study provides empirical evidence that repeated winter dead-biomass removal, rather than a single-year disturbance, is crucial for the restoration and conservation of endangered wetland plant species.

This study investigates how lake morphology, water quality, and water-level fluctuations (WLF) collectively shape wetland plant communities across 90 lakes in the Republic of Korea. By analyzing morphological indices (Index of Basin Permanence; IBP, Rawson Index; RI), WLF, water quality, and vegetation data, we identified four distinct lake groups through cluster analysis. Group C, comprising large dams, was characterized by the highest IBP and extreme WLF. Despite having favorable water quality, this group exhibited the lowest species richness, suggesting that severe physical disturbance from WLF is a primary limiting factor for wetland plant community. In contrast, Group A (estuarine reservoirs) showed stable water levels but high nutrient concentrations, which led to eutrophic conditions and communities dominated by a few tolerant species. Group D, which included small agricultural reservoirs and floodplain wetlands, had complex shorelines (highest RI) and supported the higher diversity of aquatic plants. This indicates that habitat heterogeneity can mitigate moderate physical disturbances and enhance richness. Canonical Correspondence Analysis and Variation Partitioning Analysis revealed that community structure is primarily influenced by hydrological disturbance, chemical stress (eutrophication), salinity, and shoreline complexity. These analyses confirmed that the interplay of these environmental factors explains community variation more effectively than any single factor alone. Our findings demonstrate that lake plant communities are shaped by a complex interaction of geomorphological, hydrological, and chemical factors. Therefore, effective lake management must adopt an integrated approach, considering both water-level regulation and shoreline complexity to enhance ecological integrity.

This study investigated the wetland plant community in Mije Reservoir, Gunsan City, during September and October 2024, emphasizing its ecological significance as a primary producer and habitat provider within agricultural reservoir ecosystems. The reservoir was divided into 14 distinct sectors to comprehensively assess spatial plant distribution patterns. Aquatic plants were sampled using collection anchors deployed at the water’s edge, while hygrophytes and emergent macrophytes were surveyed along transects extending from the water’s edge to the embankment. A total of 192 vascular plant species were identified, of which 73 were classified as wetland plant species, encompassing diverse life forms: 36 hygrophytes, 17 emergent macrophytes, 6 floating-leaf species, 3 free-floating species, and 11 submerged species. Notably, the survey documented the presence of two endangered species, Euryale ferox and Cicuta virosa, alongside eight invasive alien plant species. A comparative analysis with a prior survey conducted in 2008 revealed a substantial increase of 54 wetland plant species. Currently, Mije Reservoir is subject to intensive aquatic plant removal management due to observed excessive proliferation and cyanobacterial bloom. However, the presence of endangered species underscores the critical need for a more nuanced reservoir vegetation management strategy that integrates the spatial distribution and conservation status of these ecologically important wetland plants.

This study analyzed the spatiotemporal changes of wetlands in the Saemangeum watershed by comparing topographic maps from the 1918 and 2015, and analyzed the changes in connectivity among wetland habitats through wetland network analysis. The results showed that wetlands that were widely distributed around rivers and estuaries in the past have been largely lost, while artificial reservoirs around agricultural lands have increased in the upper reaches. Although the wetland area including artificial reservoirs increased slightly, most of the natural wetlands around the river channel were lost, and the dominant wetland type and distribution in the watershed changed significantly. In particular, the connectivity between coastal wetlands and inland wetlands decreased and the connectivity around small reservoirs increased, resulting in a disconnection of the wetland network structure. These changes may have a negative impact on the movement of wetland organisms and the circulation of materials, and further affecting the stability of the Saemangeum watershed ecosystem. In order to restore wetland biodiversity in the Saemangeum watershed, it is necessary to restore the past wetland areas and monitor the remaining wetlands. It is urgent to establish resilient governance and develop a restoration plan to maintain connectivity among marine, freshwater, and terrestrial ecosystems.

본 연구는 지리산국립공원 내 설산습지의 식물상 및 식생 구조를 조사한 것으로, 향후 변화 추적을 위한 기초자료를 제공하고, 나아가 관리 및 보존 방안을 제안하고자 수행되었다. 관속식물 조사 결과, 68과 138속 170종, 3아종, 20변종, 4품종으로 총 197분류군이 확인되었다. 주요 종으로는 특산식물인 키버들과 매미꽃 등 6종, 희귀식물인 물들메나무 등 3종, 그리고 식물구계학적 특정식물 5등급에 해당하는 문수조릿대 등이 포함되었다. 습지선호도에 따른 분류 결과, 전체 197종 중 습지식물은 28종(14.2%)으로 확인되었다. 목본층에서는 버드나무가 우점하였으나 초본층은 수위에 따라 식생 구성이 달랐다. 수위가 지표면보다 높은 영역에서는 절대습지식물과 임의습지식물이, 수위가 지표면과 일치 하는 영역에서는 임의습지식물과 양생식물이, 수위가 지표면 아래인 영역에서는 절대육상식물의 세력이 우세하였다. 석축의 상태와 지표수 유입량은 습지의 현재 상태 유지를 결정하는 핵심 변수로 작용하였다. 따라서 방치된 계단식 논 습지의 보전을 위해서는 석축, 수로, 지형 등 물리적 환경과 동식물에 대한 지속적인 모니터링 결과를 기반으로 한 체계적인 관리가 필수적인 것으로 판단되었다.

This study investigated the distribution and growth performance of Bolboschoenus planiculmis under varying estuarine environmental conditions. We aimed to determine the optimal planting methods and environmental conditions with respect to salinity, soil texture, and tidal regimes on its growth performance. Our findings revealed a significant reduction in B. planiculmis coverage, shrinking to 955,393 m2 in 2024, representing only 38.59% of that compared to 2004. The plant’s survival rate exhibited a clear salinity gradient: 0 ppt (89±8.01%)>5 ppt (64±4.56%)>15 ppt (37±4.25%)>30 ppt (0±0.00%). Planting density significantly influenced growth, with 24 tubers m-2 yielding the highest number of plants per tuber (14.67±0.33). A planting depth of 5 cm proved optimal for tuber germination and growth. Soil texture analysis demonstrated that a lower sand content promoted growth, with the highest density observed in soil containing 10% sand (435±6.96 plants m-2). Tidal influence also played an important role, with areas experiencing regular tidal fluctuations fostering the most successful growth. Planting tubers or young plants with attached tubers in these tidal zones led to the highest survival rates and biomass.

잠자리목은 습지 생태계의 환경의 질을 나타내는 생물 지표로 알려져 있으며, 이들의 분포와 풍부도는 습지 생태계 평가 및 생물다양성의 척 도로 활용된다. 본 연구는 환경부에서 지정·관리하는 습지보호지역 25개소를 대상으로 습지 유형별 잠자리목 분포 현황을 분석하여 서식지 보전 및 기후변화에 따른 종의 분포 변화에 관한 자료를 제공하기 위해 수행되었다. 조사 결과, 총 10과 67종이 확인되었으며, 잠자리과(Libellulidae) 24종 으로 가장 많이 관찰되었고 하천습지 52종, 산지습지 50종, 호수습지 30종, 인공습지 32종이 확인되었다. 기후변화 생물지표종인 푸른아시아실잠 자리(Ischnura senegalensis)와 연분홍실잠자리(Ceriagrion nipponicum)는 서식지가 점차 북쪽으로 확장되고 있는 것으로 나타났다. 고유종인 꼬마 측범잠자리(Nihonogomphus minor)와 산측범잠자리(Asiagomphus melanopsoides)는 개체군 크기가 작아 지속적인 모니터링을 통한 관리 방안이 필요할 것으로 보인다. 본 연구결과는 습지보호구역에 분포하는 잠자리의 생태적 특성을 조사하여 습지 생태계의 보전과 관리를 위한 기초자료로 활용될 것이다.

The Ansan Reclaimed Wetland, reclaimed in 1986 and maintained for 38 years, underwent two wetland function assessments to develop strategies for enhancing biodiversity and conservation. The biota of the reclaimed wetland showed an increase in the number of species observed across most taxa, while the number of amphibian and reptile species decreased. Among legally protected species and specific species, Aix galericulata and Lefua costata were not observed, whereas Libellula angelina were introduced. The results were categorized into “protection or improvement” and “enhancement.” Proposed conservation measures include removing planted shrubs, maintaining waterways, and installing gabion structures and wildlife corridors.

This study examined the spatiotemporal changes in Jilnal Wetland using satellite image-based time series data and field surveys. The analysis focused on changes in open water surface area and vegetation using the JRC Surface Water Monthly Water History dataset and Landsat imagery from 1984 to 2020. The impact of hydrological changes on vegetation was assessed through surveys conducted before and after the 2023 monsoon season. Results indicated a continuous decrease in open water surface area since the 1980s, with a sharp decline post-2003. NDVI analysis showed an inverse relationship between water area reduction and increased vegetation vigor and coverage. Field surveys revealed that hydrological changes directly affected vegetation structure, leading to new herbaceous communities and greater diversity post-monsoon. These findings highlight significant ecosystem changes driven by anthropogenic factors and natural succession, necessitating a comprehensive conservation strategy, including development control, hydrological management, terrestrialization prevention, and long-term monitoring.

본 연구는 출현 식물에 따른 산림습원의 생태적 특성을 분석하고 진행 중인 훼손 파악과 그 원인에 맞는 복원 방안을 제시하고자 하였다. 강원 정선 백봉령 산림습원 구역 총 20개소를 대상으로 Z-M 식물사회학적 방법에 따른 현장조사를 수행하였고, 이원지표종분석과 표조작법을 활용하여 식생 유형을 구분하였다. 각 군락별 상대우점치, 종다 양도를 산출하고 습지식물 유형 분석 및 현존상관식생도 작성을 진행하였다. 본 조사지역에 분포하는 관속식물은 48과 107속 134종 4아종 24변종 3품종으로 총 165분류군이 조사되었다. 식생 유형은 일본잎갈나무-노린재나무군락 (C1)과 들메나무-산뚝사초군락(C2)으로 구분되었다. C2는 C1에 비해 관목층을 제외한 모든 층위에서 절대습지식물 및 임의습지식물의 상대우점치와 비율이 높게 분석되어 C1이 C2에 비해 교란 및 육화가 많이 진행된 것을 알 수 있었다. 또한 2019년 인접 42번 국도의 확장공사 과정에서 신설된 6개의 배수로와 습원구역 내 수계 변화로 인한 토양 붕괴·침식·유출 및 시설물 훼손이 발견되었고, 본 산림습원을 지속적으로 보전할 수 있는 복원 공법을 제시하였다.

횡성 포동습지의 어류상 및 어류군집 특징을 밝히기 위해 6개 지점을 선정하여 2023년 4월부터 10월까지 3회 조사를 실시하였다. 어류의 채집은 하천에서는 족대와 투망, 일각망을, 호내에서는 족대와 투망, 삼중자망, 삼각망을 사용하였다. 조사결과, 6개 지점에서 5목 12과 33종 5,616개가 채집되었으며, 우점종은 참붕어(29.5%), 아우점종은 피라미(24.1%)였고, 그 다음으로 참갈겨니(10.3%), 빙어(8.3%), 붕어(5.7%), 돌고기(4.0%), 긴몰개(3.7%), 떡붕어(2.8%) 등의 순으로 우세하였 다. 환경부지정 멸종위기 야생생물은 II급 한강납줄개와 돌상어 2종이 채집되었고, 한국고유종은 한강납줄개, 쉬리, 긴몰개, 돌상어, 돌마자, 참갈겨니, 참종개, 새코미꾸리, 눈동자개, 퉁가리, 꺽지, 얼록동사리 12종(고유화율 36.4%)이 확인되었다. 회유성(강하형) 어종은 뱀장어 1종, 육봉형 어류는 빙어와 밀어 2종이 채집되었으며, 외래어종은 이스라엘잉어와 떡붕어, 배스 3종이 채집되었는데, 이중 배스는 생태계교란 생물로 지정된 종이다. 횡성 포동습지는 하천생태계와 호소생태계가 함께 있기 때문에 다양한 어류 서식지를 제공하고 있어 멸종위기종 한강납줄개와 돌상어를 포함하여 많은 종이 서식하여 보존가치 가 높은 곳으로 판단되었다. 하지만 교란요인으로 하천공사와 하천내에 설치된 보, 생태계교란 생물 배스의 서식 등이 확인되어 종합적인 보존대책이 요구되었다.
