The document discusses biodiversity indicators for monitoring the Kunming-Montreal Global Biodiversity Framework agreed upon at COP15. It provides context on the history of biodiversity indicators in CBD discussions and lessons learned. Currently, 26 headline indicators have been agreed for the monitoring framework, but 10 still require methodology development. Issues being discussed include identifying gaps, aggregating and disaggregating data, guidance for parties, and inclusion of all stakeholders. The ad-hoc technical expert group will review existing indicators and provide recommendations to help operationalize the monitoring framework.
