aBased on a comparison with data in ''Cost and Cost Trends for Forestry Practices in the South" by Straka et al. (1989), these practices and costs are very similar to those required for establishing loblolly pine on old-field sites in the South.

bCampbell chose 6735 trees/ha for evaluation of costs. Using his estimate of $0.17/seedling, the costs were modified to assume 2100 trees/ha and use of weed control methods for 2 years instead of 1 year.
