Abstract

In the Southern Appalachians, metrics for quantifying the geometric shape of the land surface (terrain shape index or "tsi") and of the landform (land form index or "lfi") were developed and found to be correlated to yellow-poplar site index. However, the utility of these metrics for predicting site index for oaks in the Ozark Highlands has not been evaluated. We examined the relationship between black oak site index and the tsi and lfi with other measures of terrain, including the slope position and the (transformed) slope-aspect using data collected in 120 0.12-ac experimental units at the Sinkin Experimental Forest in southeastern Missouri. The tsi and lfi were each significant (P
