    World Trees Report 2021 Warning: 30% of tree species in the wild are threatened with extinction

    According to a new World Trees Report 2021 released -A third (30%) of the world’s trees are at risk of extinction. The new report by BGCI was released today. The report reveals that at least 64% of all tree species can be found in at least one protected area, and about 30% can be found in botanic gardens, seed banks, or other ex situ collections, its a warning for the world and action need to be taken.

    • Well-known trees such as magnolias and dipterocarps among most threatened, with oaks, maple (Acer) and ebonies also at risk.
    • Agriculture, logging, and livestock farming are the top threats but climate change and extreme weather are emerging dangers.
    • Islands including St Helena (69% of trees threatened), Madagascar (59%) and Mauritius (57%) have highest proportion of threatened trees.
    • Report offers five recommendations to bring species back from the brink and provides hope for future if conservation efforts continue.

    Botanic Gardens Conservation International (BGCI) has published a landmark State of the World’s Trees report. The report, compiling work led by the Global Tree Assessment (GTA), is the culmination of five years of research to identify major gaps in tree conservation efforts. It is one of the first assessments of the world’s threatened trees. 

    The greatest threats facing trees include habitat loss from agriculture and grazing, followed by over-exploitation from logging and harvesting.

    The report finds that 1 in 3 trees currently harvested for timber are threatened with extinction.

    The report finds hope for the future, however, as conservation efforts led by the botanical community worldwide are growing. Identifying which trees are at risk and ensuring these are protected is the most effective way to prevent extinction and restore endangered species.

    The report reveals that at least 64% of all tree species can be found in at least one protected area, and about 30% can be found in botanic gardens, seed banks, or other ex situ collections, but further action is needed.

    Climate change and extreme weather are emerging threats to tree species globally. As the temperature and weather of the world changes, many trees risk losing areas of suitable habitat. This affects species in both temperate and tropical habitats, with Cloud Forest tree species of Central America being at particular risk.

    Hope for tree remains

    Despite nearly a third of tree species threatened with extinction, the report indicates hope for the future if conservation efforts continue and further action is taken. With the publication of the State of World’s Trees Report, BGCI hopes to catalyse action among policymakers and conservation experts across the world.
