According to the Oak Hill Foundation there are 20 different species of oak tree that can be found across Indiana which,

play a critical role in supporting plant and animal communities across Indiana and the world. Many partners in urban forestry and conservation are working to promote the important role oaks play, including being a primary habitat for over 500 caterpillar species

Unfortunately these crucial trees are being threatened by an invasive fungus spread through the trees' root systems. Bretziella fagacearum, or oak wilt as it is known, has the capacity to kill affected trees within a matter of weeks.

According to the Purdue University Extension this disease is affecting the red and black oak groups of trees across Indiana and much of the Midwest, including Michigan.

Red and black oaks are infected with the disease in early summer, which will generally result in rapid wilt and tree death by late summer. The first symptoms of oak wilt occur in the top portions of trees.

Experts say it's time to call for backup when the leaves in the center of your oak trees begin to die or fall off. If not treated or disposed of properly oak wilt will continue to spread to nearby tree groups leaving devastation in its path.
