| 説明 | American chestnut (Castanea dentata) leaves, Ricketts Glen State Park, Luzerne County, along the Grand View Trail.American chestnuts were once among the most common forest trees in eastern North America. A blight early in the twentieth century eliminated most of the trees; however, the root systems continue to produce saplings. The young trees usually succumb to the blight before reaching maturity.The American Chestnut Foundation and other organizations are working to develop a blight-resistant strain. |
