Outline of Final Research Achievements

Protected areas are the crux of biodiversity conservation when managed effectively. Focusing on threatened plants, this project evaluated conservation effectiveness of national and quasi-national natural parks, the core protected area system of Japan, and tried to identify social attributes of the parks which could effectively enhance the conservation effectiveness. Focal parks are on average effective in reducing local extinction rate of threatened plant species, while the effectiveness differ greatly among the parks. Although multiple social attributes of the parks are considered, neither of the collected attribute was significantly associated with the conservation effectiveness.

Academic Significance and Societal Importance of the Research Achievements

設置した自然保護区での保全有効性の評価および保全有効性の改善は、生物多様性保全上重要な課題であるだけでなく、愛知目標12や世界植物保全戦略目標7の達成評価、およびポスト愛知目標を検討する上で重要な役割を果たす。本課題は、国内で殆ど取り組みのない国立・国定公園の保全有効性の評価を実施した点に大きな社会的・保全科学的意義がある。
