Thursday, 29 March, was yet another warm, sunny day in Dublin. In the morning, the PC20 working group on timber species, medicinal plants and agarwood-producing species discussed, among other items, whether non-detriment findings (NDFs) should be conducted at the genus- or species-level for agarwood-producing species, and which agarwood products should or should not be controlled by CITES. Later in the morning, the PC members continued and finalized their discussions on the Cedrela and Dalbergia spp amendment proposals in their working group.

In the afternoon, PC20 reconvened in plenary, heard reports from a number of the working group chairs while awaiting the final working group reports and recommendations. Approved working group recommendations on nomenclatural issues, the Review of Significant Trade (RST) and the periodic review of the Appendices. The PC also heard an oral report from the Secretariat on reporting on trade in artificially propagated plants [Decisions 14.39 (Rev. CoP15) and 14.40 (Rev. CoP15)] and regional reports.

While the PC has made excellent process, working groups for some of the more warmly debated agenda items have yet to present recommendations in plenary, so much work remains for Friday.

In the evening, PC participants took a tour of historic Dublin Castle, an 800 year-old structure which over the years has served many purposes, from a defensive fortification to a royal residence to a venue for meetings like CITES.
