Modeling the habitat of the red-crowned crane (Grus japonensis) wintering in Cheorwon-gun to support decision making

Cheorwon-gun is an important wintering area for the red-crowned crane (Grus japonensis). Although eco-tourism has been recently proposed as a means to stimulate the local economy, it may have adverse effects on the crane. We believe a science-based conservation plan is needed to mitigate these negative effects. To this end, our study had three objectives: (1) to analyze the red-crowned crane habitat and its suitability in Cheorwon-gun, using field surveys and habitat modeling; (2) to check the feasibility of alternative habitat patches across demilitarized zones (DMZs); and (3) to propose a conceptual diagram that minimizes habitat loss during development activities. We aim to quantify habitat suitability, the farmland area needed to support existing crane populations in wintertime, disturbance caused by human activities, and vehicular spatial patterns. These data could be used in spatial planning. The framework of this study and the process of making a conceptual diagram could be applied to other areas where there is a conflict between development and habitat conservation.
