Progress on national biodiversity indicator reporting and prospects for filling indicator gaps in Southeast Asia

With tremendous biodiversity but increasing threats, Southeast Asia faces challenges in meeting its commitments to the Convention on Biological Diversity’s 2020 Aichi Targets. The use of indicators to monitor, evaluate and guide conservation progress is increasingly urgent. We quantified indicator use by 10 Southeast Asian governments in the 4th and 5th national reports submitted to the Convention on Biological Diversity in 2010 and 2015. We found indicator use variable among nations but increasing. Use of quantitative trend indicators doubled from an average of 6–12. There was no change in the number of non-quantitative (mean of 2) or quantitative baseline indicators (those measured once; mean of 9). Indicators most frequently addressed habitat condition and extent, species diversity, protected areas, and agriculture (means of 2–6 indicators each). They were rarely used (mean ​
