Stand Density Index (SDI) equations were developed and presented for upland hardwoods in southern Ohio. The relationship between SDI and stocking percent from upland hardwood stocking charts were developed, and a diagram displaying this relationship is presented. Critical stand density boundaries equivalent to stocking percent on stocking charts were defined: (1) the C-level of stocking (SDI < 125), (2) the B-level of stocking (125 ≤ SDI < 215), and (3) the A-level of stocking (215 ≤ SDI ≤ 250). A fourth boundary—the region where competition-induced mortality begins—was determined through empirical evidence at an SDI = 175, or 81% stocking. How these boundaries can be utilized in various management strategies is presented.
