More than half of native European trees face extinction, warns study

Ash, elm and rowan among trees threatened by pests and pollution, says biodiversity report

More than half of Europe's endemic trees are threatened with extinction as invasive diseases, pests, pollution and urban development take a growing toll on the landscape, according to a study.

Ash, elm and rowan trees are among those in decline, says the assessment of the continent's biodiversity, which could complicate efforts to tackle the climate crisis through reforestation.
