Dutch Elm disease derived from a member of the sac fungi and is originally native to Asia. It’s recent migration to Europe and the Americas is thought to be brought by the elm bark beetle. After finding its way to America in 1921, Dutch Elm Disease devastated a native population of elms which did not have the chance to develop resistance to the disease.

The first sign of Dutch Elm is weakened and yellowed branches at the top of the tree. The tree recognizes the fungi and starts to plug its receivers in an attempt to stop the fungus from spreading. However, in its attempt to stop the fungus it also prevents itself from carrying nutrients to the other parts of the tree. Overtime, the tree continues weaken and turn yellow causing branches to die. Eventually the roots die, and the whole tree succumbs to the disease. You can also recognize Dutch Elm by cutting into a branch of the tree. A tree infected with Dutch Elm Disease will have dark streaks of discoloration in the outer rings of the wood.
