Fort Myers Naples, FL, August 31, 2026 —
In the United States, scientists are embarking on efforts to restore the American elm tree, a species that has suffered significant decline primarily due to Dutch elm disease. The disease, caused by a fungus, has drastically reduced the population of these iconic trees across the nation.
Researchers are currently focusing on identifying and cultivating natural resilience within the elm population. In Vermont, a specific initiative is underway where young elm saplings are being subjected to tests for inherent resistance to Dutch elm disease. This process involves inoculating the saplings with spores of the disease-causing fungus.
The objective of these trials is to identify any saplings that exhibit natural resistance and survive the inoculation. These surviving trees are intended to become the foundation of a future breeding program. By utilizing these resilient individuals, scientists hope to develop a new generation of American elms that are more tolerant of Dutch elm disease.
The ultimate goal of this research is to reintroduce disease-tolerant American elms back into natural landscapes and urban environments, thereby aiding in the restoration of the species. The contractor or institution leading this specific testing in Vermont was not specified in the provided information. Further details regarding the timeline for the breeding program or projected dates for potential reintroduction efforts were also not available.
