The Global Tree Assessment - Understanding Tree Status Worldwide and Inspiring Conservation Action | Botanic Gardens Conservation International The Global Tree Assessment provides information on the threats to trees and provides the data needed to take effective conservation action.

The Global Tree Assessment reached a milestone with over 80% of trees now assessed on the @IUCNRedList. Trees are now the largest comprehensively assessed group on the Red List, thanks to the work of all our partners and collaborators!

In July, @BGCI and the Global Tree Assessment co-organised a ThinkTank @osaconservation in Costa Rica, bringing together participants from across Mesoamerica for a week to discuss how to prioritise and mobilise tree conservation in the region.

Integrated conservation action plan developed to conserve Chile’s threatened endemic tree species | Botanic Gardens Conservation International A workshop organised by BGCI highlights the urgent need for actions to conserve Chile's threatened endemic trees.

This year we have continued our work towards conserving the world’s tree species. @GTA_GTSG collaborated with @IUCN_CPSG on conservation planning workshops for threatened trees in Malaysia and Chile.
