The Post 2020 GBF has reached stronger and clearer wording, due to clearer scientific consensus and very active participation by conservation geneticists through numerous policy channels, though there is scope for improvement in the final negotiations. The role of scientists in the CBD process needs strengthening, via greater involvement of scientists and more invitations for scientists, such as indicator evaluation and testing (e.g. the Ad Hoc Technical Expert Group). Communication between scientific groups, the CBD Secretariat, Parties, the IUCN, IPBES, GEO BON, and other stakeholders during implementation of the GBF is vital for capacity development and shared learning, which will take significant time and effort.
