It is finally here! The State of the World's Tree Report, documents the work of GTA and all of its 500 individual assessors & 60+ partners. For the first time identifying at least 30% of the world's trees as threatened in the wild.

This is soooooo cool. The #EricaGCC is such an exciting project and has the ability to have a huge positive #conservation impact for a ecologically important genus.
#EricaGCC will have a poster up at #Botany2021 botanyconference.org/engine/… Looking forward to spreading the word at another excellent (midnight?) meeting!

My #ExtinctInTheWild #CapeFlats Ericas were used for genetic tests. This pioneering work will help put these species back in the wild. Really happy to be part of the @bgci #EricaGCC. 🙏🏽 @PirieMike @Tree_Spotter
