What tree type does Dutch Elm disease predominantly affect?

Dutch Elm disease predominantly affects deciduous trees, specifically targeting the elm species. This disease is caused by a fungal pathogen, primarily Ophiostoma ulmi, which is spread by bark beetles that infest infected trees. Deciduous trees are characterized by their broad leaves and annual leaf shedding, which contrasts with conifers that have needle-like leaves and bear cones.

In the case of elm trees, the disease leads to wilting, yellowing of leaves, and ultimately death as it disrupts the tree's vascular system, preventing water and nutrients from reaching the leaves. Understanding that Dutch Elm disease is associated with specific tree types, particularly elms within the deciduous category, is crucial for forest management and prevention efforts.
