Dutch elm disease fungus is shifting across Scandinavia, creating new hybrid threats

A new study tracking the pathogen behind Dutch elm disease across Scandinavia reveals subspecies are migrating northward and interbreeding, potentially creating more aggressive strains. For forestry companies, agricultural policymakers, and urban planners, this suggests the disease's range and severity may expand, requiring updated management strategies for one of Europe's most economically damaging forest pathogens.
