Forest Service American Chestnut Cooperative Research Program
Though the economic and ecological impacts are impossible to assess, there is little doubt that the single greatest plant tragedy to occur in this country was the loss of the American chestnut tree. Efforts to control chestnut blight and reestablish American chestnut trees have been futile. Recently there has been a discovery in Europe that may eventually provide the basis to successfully reintroduce American chestnut trees in this country: Certain less pathogenic (hypovirulent) strains of the chestnut blight were reported to inhibit growth of more virulent strains of the blight, and many of the European chestnut trees have recovered from the blight.
