Abstract
Three initial spacings from a 30-year-old unthinned loblolly pine plantation were evaluated to estimate the historical returns achieved at various rotation lengths and for the impact of single and multiple products. The plantation was established on a well-drained interior flatwoods clay site in North Central Mississippi. Historic rates of return using actual price and cost data are reported. Generally, the optimum pulpwood rotation was 20 yr, and optimum sawtimber rotation was 30 yr. Wider spacings produced higher returns for both pulpwood and sawtimber rotations. When multiple products were considered (joint production of sawtimber, chip-n-saw, and pulpwood), greater returns than the single product rotations were obtained, and wider spacings consistently produced higher economic returns.
