Dutch elm disease
Bark beetle blight
Dutch elm disease is a fungal infection that kills elm trees, spread by bark beetles.
The disease blocks water transport in the tree, causing leaves to wilt and branches to die.
It devastated elm populations across North America and Europe in the twentieth century, transforming urban landscapes where elms had lined streets for generations.
