Global Tree Assessment


What is the Global Tree Assessment?
The Global Tree Assessment aims to provide conservation assessments of all the world’s tree species by 2020. This will identify those tree species that are at greatest risk of extinction. The goal of the Global Tree Assessment is to provide prioritization information to ensure that conservation efforts are directed at the right species so that no tree species goes extinct.

Who is coordinating the Global Tree Assessment?
The Global Tree Assessment is an initiative led by BGCI and the IUCN/SSC Global Tree Specialist Group. Work is ongoing to develop an even more extensive global collaborative partnership, involving the coordinated effort of many institutions and individuals. If you would like to join, find more information on our how to join page.

Why do we need to produce conservation assessments for trees?
Despite the importance of trees, the majority of species are still lacking a conservation assessment. Many are threatened by over-exploitation and habitat destruction, as well as by pests, diseases, drought and their interaction with global climate change. In order to estimate the impact of such threats to trees there is an urgent need to conduct a complete assessment of the conservation status of the world’s tree species. The GTA will allow prioritisation of conservation action to ensure that no tree species goes extinct.

How can I get involved?
There are many ways that you can get involved in the GTA from providing information for assessments, reviewing assessments or providing financial support. See our how to get involved page for more information.
