<p>American chestnut (<i>Castanea dentata</i>) leaves along the Kunes Camp Trail, Clearfield County, within the Quehanna Wild Area of Moshannon State Forest.
</p><p>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 new growth. 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.
