내륙 습지보호지역의 생태계 건강성 평가 지표 시범 설정 = Establishing Ecosystem Health Assessment Indicators for Terrestrial Wetland Protected Areas

다국어 초록 (Multilingual Abstract)

This study is a preliminary research with the aim of establishing an ecosystem health assessment system that can be reflected in the management plans of protected inland wetland areas in South Korea, based on the results of a detailed survey conducted in these areas. This study sought to derive indicators of ecosystem health that should be prioritized for efficient management. The Delphi survey method was used in two rounds to identify potential indicators. The analysis results revealed that, in the field of the physicochemical environment, four indicators were selected: wetland area (㎡), wetland flow volume (㎥), water quality, and groundwater level (m). Regarding biodiversity, the indicators included the total number of observed species, total number of major species, average species diversity index of major animal taxonomic groups, number of apex predator species, number of legally protected species, and vegetation diversity index. For stress factors (threats), the indicators selected were the number of ecosystem-disrupting wildlife species, surrounding land-use status, artificial structures, number of invasive species, and human interference. The relative importance of these indicators for assessing the ecosystem health of inland wetlands was as follows: biodiversity (0.40); physicochemical environment (0.36); and threats (0.25). In terms of applicability, over 70% of experts agreed that these indicators were applicable to all types of wetlands, including mountainous, riverine, and lake-type wetlands.
