苏拉威西、摩鹿加群岛和小舜达的瓦拉西亚生物地理区以特殊的地方性而闻名全球，但目前正在成为印度尼西亚的发展前沿。我们评估了整个地区森林损失和碎片化的模式和驱动因素，并使用动态森林砍伐模型预测到2053年的未来森林砍伐。2000年至2018年期间砍伐了多达10231平方公里的森林，预计到2053年还将减少49570平方公里，不同次区域的年砍伐率在0.09%到2.17%之间(平均为1.23%)。关键的生物多样性区域(地方性生物多样性和受威胁生物多样性的优先地点)如果面积较小、沿海且未受保护，则特别容易遭到砍伐。如果保护干预措施要有针对性和有效，就必须认识到砍伐森林模式和驱动因素的次区域差异。我们提供了一个宝贵的基线来监督Wallacea的新发展进程，因为印度尼西亚正在经历深刻的政策变化，这将为环境治理和保护带来挑战和机遇。
The Wallacea biogeographic region of Sulawesi, the Moluccas and Lesser Sunda is globally renowned for exceptional endemism, but is currently emerging as a development frontier in Indonesia. We assessed patterns and drivers of forest loss and fragmentation across the region, and used dynamic deforestation models to project future deforestation to 2053. Up to 10 231 km2 was deforested between 2000 and 2018, and a further 49 570 km2 is expected to be lost by 2053, with annual deforestation rates ranging between 0.09% and 2.17% in different sub-regions (average: 1.23%). Key biodiversity areas (priority sites for endemic and threatened biodiversity) are particularly vulnerable to deforestation if they are small, coastal and unprotected. Sub-regional variation in deforestation patterns and drivers must be acknowledged if conservation interventions are to be targeted and effective. We provide a valuable baseline from which to monitor Wallacea’s new development course, as Indonesia undergoes profound policy changes that will provide both challenges and opportunities for environmental governance and conservation.
