Scientists are working to restore American elms by using the disease that has harmed them. A research ecologist is leading this effort. The goal is to grow trees that can tolerate the disease.

Young elm trees were injected with disease spores to test their resistance. The trees that survive will be used in a breeding program.

These trees will eventually be used in various settings, including forests and backyards, to increase the number of disease-tolerant elms. Further details about this project are available from the source.
