Systematic conservation planning of protected area is a promising approach for enhancing effectiveness of biodiversity conservation. Protected area that restricts economic activity is regarded as social cost. Therefore, it is essential to maximize biodiversity in protected area while minimizing its area that surrogates the costs. Evaluation actions based on their cost effectiveness provides an algorithm that can solve the minimum set coverage. In this study, we compiled spatial data of plant diversity and protected area (e.g. national park) in Japan, and examined the minimum set of protected area for conserving plant species richness. Our results demonstrated the current status of protected area and additional conservation area for covering gap species (which is not protected in the present protected area) and finally identified priority area for maintaining evolutionary potentials of plant diversity hotspots in Japan.
