Forest Management

If the stand described in "Thinning" was not thinned, rather the timber not cut was theoretically allowed to grow for 15 years.  At stand age 70 years the trees were assigned the highest possible board foot value based on DBH as per USDA Forest Service grading rules where:

  • <9.6"=pulpwood

  • 9.6-12.5"=F3 log grade

  • 12.6-15.5"=F2 log grade

  • >15.6"=F1 log grade


At stand age 70 years--

Total value of unthinned 1 acre stand at stand age 70 years=$4418.23

Assumed 15 year DBH growth rates for the species are:

  • Red Oak-3.75 inches

  • Chestnut Oak- 3 inches

  • Yellow-Poplar- 4.5 inches

  • Black Cherry- 3.75 inches

  • Soft Maple- 3 inches
