Yellow-Poplar Site Quality Related to Slope Type in Mountainous Terrain
Abstract:Site index and topographic variables were measured on 112, ¼-ac sample plots with yellow-poplar overstory in the Blue Ridge Province of the Southern Appalachian Mountains. The plots were grouped by slope type--nose, side, or head--and multiple regression analysis was used to develop equations for predicting height at 50 years. Estimated site index was significantly less on side slopes than on head slopes. Stand age was the most important variable in both equations, followed by aspect and land surface shape. The equations accounted for 79% of the variation of yellow-poplar height on head slopes and 84% on side slopes. North. J. Appl. For. 4:189-192, Dec. 1987.
