Exact Creation Date



Beech leaf disease (BLD) was first described in Ohio in 2012. Since then, it has spread to the north and east, impacting beech trees wherever it is found. Beech leaf disease was detected in Maine in 2021 in Lincolnville, Waldo County. Since then, the severity of the disease in known locations has increased markedly, and the geographic distribution of the disease has expanded well outside of the area of the original detection. BLD impacts all species and cultivars of beech and all ages of beech trees. Due to the relatively short time BLD has impacted trees in North America, much about the disease is still unknown, and BLD management and treatments are still under development. Recently, new information has been shared on BLD treatment to assist land managers and homeowners in protecting high-value beech trees.
