More than 30 percent of the world’s tree species are threatened with extinction, according to the International Botanic Gardens Conservation Report.
According to the study, among other trees, oaks, magnolias and tropical trees are endangered.
Experts say 17,500 species of trees are at risk, and that threat is twice as high as that posed by mammals, birds, amphibians and reptiles together.
Conservation groups are calling for urgent efforts against the backdrop of threats such as deforestation, deforestation and climate change.
About 142 species of trees have already disappeared from the wild, while 442 are on the verge of extinction as less than 50 of each tree remains.
Scientists estimate that millions of animals and plant species are threatened with extinction. Over the past 300 years, global forest area has shrunk by about 40 percent and 29 countries have lost more than 90 percent of their forest cover.
