A summer-long effort in Vermont aims to curb Dutch elm disease by testing a new generation of elm trees for resistance. Researchers have been injecting thousands of trees with Dutch elm disease spores to study whether this updated stock can withstand the notorious blight that has ravaged elm populations across the United States and Canada for decades. The work unfolds in Benson, Vermont, where a conservation information manager from The Nature Conservancy administers injections to young elms, part of an experimental approach to identify trees that may possess natural defenses against the disease. The project captures a broader push to understand and combat a pathogen that has historically decimated urban and forest elm populations, with the goal of cultivating trees that could survive future outbreaks. The initiative comes as scientists assess the implications of breeding or engineering elm varieties that can resist Dutch elm disease, hoping to provide long-term relief for affected ecosystems.
