Hybrid American chestnuts resistant to the chestnut blight fungus may soon come to be avialable for landscape scale reintroduction. In order to help forest managers decide how to reintroduce the species back into their forests, we studied the performance of chestnut seedlings planted in three silvicultural treatements on the Daniel Boone National Forest. We were particularly interested in how the treatements, which vary in light levels, affect not only the growth of the chestnuts but also the growth of other tree species. After three years, we found that chestnuts grew the largest in the treatements that created high light levels, however sprouts and seedlings of other tree species also grew largest in this treatment. Chestnuts were best able to compete with cooccuring tree species in the treatment that created intermediate light levels, which inhibited the growth of the shade intolerant species. While growth was maximized with high light, the chestnuts will likely have a better chance at remaining dominant or co-dominant when planted in treatements that create intermediate light conditions.
