Gradient analysis of the distribution of a fungal disease of Cornus florida in the southern Appalachian Mountains, Tennessee
Wilds SP. 1997. Gradient analysis of the distribution of a fungal disease of Cornus florida in the southern Appalachian Mountains, Tennessee. Journal of Vegetation Science. 8:811-818
Determined the distribution of dogwood anthrachnose in the western portion of Great Smoky Mountains National Park. Found a correlation with changes in elevation, slope curvature, slope position and potential soil moisture. Factors contributing to disease severity do not change significantly between disturbed and undisturbed sites. The highest mortality rates are restricted to dense stands in damp, sheltered sites at low slope positions, implying that surviving populations of flowering dogwood may represent a biased genetic subset of the original population. Used Geographic Information System (GIS).
