Beech leaf disease (BLD) is a novel pathogen affecting the American beech tree (Fagus grandifolia). Discovered in Ohio in 2012, it has since spread rapidly across eastern North America and was first observed in Michigan in 2022. BLD disproportionally affects understory saplings, with mortality occurring within 2 to 5 years, though mortality of overstory trees has also been observed. As such, this pathogen has great potential to harm Michigan beech-maple forests. Early detection and rapid response (EDRR) are crucial to minimize these effects. To aid in ongoing EDRR efforts, our University of Michigan capstone project team surveyed 21 plots in southeast Michigan for disease symptoms and forest structure. We will synthesize the results of this survey and a comprehensive literature review into a report and presentation aimed at providing management strategies to a variety of stakeholders. We will also host workshops and produce educational materials to increase public awareness.
