New Haven Parks Department Studies Beech Leaf Disease Impact on Urban Forests
The New Haven Parks Department is conducting a study in East Rock Park to understand and mitigate the effects of beech leaf disease on urban forests. This initiative involves cutting down some infected American beech trees while treating others, aiming to determine the future landscape of urban forests over the next 50 years. American beech trees, known for their smooth gray bark and ability to grow up to 100 feet tall, are a significant component of eastern U.S. forests. However, their populations have been declining for the past 15 years, exacerbated by beech bark disease and, more recently, beech leaf disease. The latter, caused by an invasive microscopic worm discovered in Ohio in 2012, feeds on beech buds, causing leaves to curl, darken, and lose their photosynthetic capacity, ultimately killing the tree within two to ten years. The study seeks to find effective strategies for managing this rapidly spreading sickness.
