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.
