Abstract:

Flowering dogwood (Cornus florida L.), one of the most common understory tree species in eastern North America, currently is threatened throughout its native range by a fungus that causes dogwood anthracnose. This aggressive disease rapidly kills dogwood trees and mortality has exceeded 90% in some forest types. The health and ecological integrity of forest ecosystems throughout the eastern United States are threatened by the rapid decline of dogwood populations. The severity and rate of infection are reported to vary with several environmental factors. Within individual stands, disease severity increases with decreased light availability and increased moisture. Management techniques to control anthracnose have received little attention; however, recent findings suggest that prescribed burning may offer an effective management tool for controlling anthracnose.
