Abstract

Basswood (Tilia americana L.) stands in the Lake States have been experiencing defoliation since around 1979. These symptoms were originally attributed to frost damage because they occur in early spring. However, the pattern of damaged trees was atypical of frost injury. Only basswood trees were affected, and there was no relationship to sites known to be frost pockets.
