At least 30% of the world's tree species are on the verge of extinction due to climate change, the BBC writes.
Endangered trees include oak, magnolia, and tropical trees.
A total of 17 500 species of trees are threatened with extinction, according to a report by the London-based Botanic Gardens Conservation International (BGCI).
"There are about 60 000 species of trees in the world. These species need protection," the report said.
