Experts say up to 17,500 plant species are endangered, double the total number of mammals, birds, amphibians and reptiles combined.
Specifically, large tropical trees in the Dipterocarpaceae family are being lost to the expansion of palm oil plantations, magnolias are endangered by plant collection, oaks are losing their habitat and habitat in parts of Mexico, Chile and Argentina, ebony and rosewood trees are being cut down for timber in Madagascar and ash trees are dying from pests in the UK and North America.
Half of all magnolia species are threatened with extinction in the wild.
Some 142 tree species have disappeared from the wild, while 442 species are endangered with less than 50 individuals remaining in the wild.
The biggest threats to trees globally are deforestation for farming (affecting 29% of species), logging (27%), clearing for grazing or farming (14%), clearing for development (13%), and wildfires (13%).
Over the past 300 years, global forest cover has declined by about 40%, and 29 countries have lost more than 90% of their forest cover. Scientists estimate that one million animal and plant species are threatened with extinction.
