Between a third and half of the world’s wild tree species are threatened with extinction, posing a risk of wider ecosystem collapse, the most comprehensive global stocktake to date warns.

Medicinal plants harvested from the wild remain of immense importance for the well-being of millions of people around the world. Providing both a relief from illness and a source of income, over 70,000 plant species are thought to be medicinal. Loss of habitat combined with over-harvesting threatens the survival of many of these plant species.
