Economic analyses were conducted to investigate the effects of initial planting density on the profitability of loblolly pine (Pinus taeda L.) on nonindustrial private forestland (NIPF) in East Texas. Five planting densities of 870, 725, 620, 540, and 484 trees per acre (tpa) representing spacings of 5x10, 6x10, 7x10, 8x10, and 9x10 ft, respectively, were investigated. Land expectation values were used to determine the financially optimal thinning and final harvesting schedules (including rotation length and the timing, frequency, and intensity of thinning). Five site indices (50-90), six real alternative rates of return (ARR) (2.5-15.0%), and three thinning options (0, 1, and 2) were employed. Results indicate that two thinnings appear to be the financially optimal number of thinnings for most site index-ARR scenarios. The planting spacing of 8x10 ft is optimal when ARR is low, and the 9x10 ft spacing is optimal when ARR is high.
