Forest Management

If the stand described in the "Thinning" scenario was not thinned, rather the timber cut using a diameter limit harvest of 14 inches allowing the residual to grow for the 15 year period with all timber assigned the highest possible board foot value based on DBH as per USDA Forest Service grading rules where:

  • <9.5"=pulpwood

  • 9.6-12.5"=F3 log grade

  • 12.6-15.5"=F2 log grade

  • >15.6"=F1 log grade.

The value of the timber removed in the 14" diameter limit

cut at stand age of 55 years was compounded simply at

3% for fifteen years and added to the value of the

residual stand at stand age of 70 years.

Total value of one acre stand

at stand age 70 years after a

14" diameter limit cut =$6142.29

Assumed  15 year DBH growth rates for the species are:

  • Red Oak-3.00 inches

  • Chestnut Oak- 2.25 inches

  • Yellow-Poplar- 3.12 inches

  • Black Cherry- 3.00 inches

  • Soft Maple- 2.25 inches

  • Hard Maple- 2.25 inches
