Outline of Final Research Achievements

In this project, we set up the first long-term forest dynamics plot in in the seasonal dry forest of Ankarafantsika National Park, NW Madagascar Madagascar (15 ha). We placed unique aluminum tags to all woody stems with diameter at breast height greater than 5 cm, and recorded their diameter, location (with accuracy of 0.1 m) and species identity (distinguishing a total of 143 tree species). From this, we described forest structure (2400 stems per ha, mean tree height 8.8 m) and above ground biomass to provide the basis for evaluating forest ecosystem services, including carbon storage, food provisioning to frugivorous animals, etc. We also set up 120 seed traps and initiated long-term monitoring the phenological patterns of seed, fruit and leaf litter production.

Academic Significance and Societal Importance of the Research Achievements

本研究はマダガスカル初、また、世界で3番目の長期森林動態調査区の設定により、日本の生物他多様性研究と森林科学研究の国際化に貢献する。地球温暖化に伴う気候変動は熱帯乾燥林地域に旱魃をもたらすことがモデルなどから予測されるなか、本調査区は熱帯乾燥林のレジリアンス評価の基盤を提供する。また、世界の熱帯乾燥林の多くが、非持続的な土地利用(薪炭材採取目的のための伐採や火入れによる農地や放牧地への転換)により、世界的に急速に消失しつつある中、原生的な植生の記載とその生態系サービスを行うことは、生物多様性保全や持続的土地利用計画政策につながるという社会的意義も持つ。
