Jeju Island, the research area, has been registered as a UNESCO World Natural Heritage Site and has high biodiversity and ecological value, such as designation as a global geopark and biosphere reserve. It also has a beautiful landscape, so it is not only necessary for conservation but also highly demanded as a landscape resource (Kim et al., 2015; Ko, 2011). Accordingly, it is necessary to prioritize the conservation area that can reconcile the conflict between indiscriminate development and nature protection, as well as to establish potential offset sites for ‘No Net Loss’ in order to respond to development impacts. Selecting conservation areas based on biodiversity value can be an effective offset decision-making tool on where and how to prioritize conservation policies (Li et al., 2021; SANBI & UNEP-WCMC, 2016). There have been many studies on biodiversity conservation between excellent ecological value and development pressure in Jeju Island, but there are almost no studies on the implementation conditions of the offset or offset sites. We here aim to map a conservation area map in consideration of the environmental characteristics of Jeju Island and to select a potential offset area that can practically work offset. We will use ‘Zonation’ program, which is a systematic conservation planning-based model. Zonation is a useful land planning tool that can minimize development impact and realize biodiversity offset (Wintle, 2008; Lethomaki & Moilanen, 2013). The biodiversity attributes inputs required for running Zonation are potential habitat data using MaxEnt and environmental variable data. As a result, we will identify the spatial range and location of the potential biodiversity offset area through Zonation Priority Rank Map output. In addition, we can also analyze their spatial and environmental characteristics, and group out the shape of potential offset site composition (size or pattern). This study can be utilized as a basis for feasible offset policy by proposing potential offset areas through selecting conservation areas in Jeju Island. This work was conducted with the support of the Korea Environment Industry & Technology Institute (KEITI) through its Urban Ecological Health Promotion Technology Development Project, and funded by the Korea Ministry of Environment (MOE) (2020002770003).
