Catalog #16

Applying Group Selection in Central Appalachian Hardwoods
To develop practical guidelines for using the group selection practice on a sustained yield basis.
expected to continue
Location on the Fernow Experimental Forest is compartment 60 at Stonelick. NRO with site index of 70. 
Assume annual per acre board foot growth of 300 (International) thus at 31 acres, 20 year totals 186,000 board feet total volume (ideal).
Case History as stands become available. Initially will concentrate on NRO site indices. 
First area: 31 acres in size on a 20-year cutting cycle with a site index of 70 for oak.
Group selection cuts applied to individual cases.
Regeneration will be quantified as related to openings, the area between openings, and the total stand.
Independent: group selection regeneration methods

Dependent: stand reproduction and yields

Remeasurements are on a 2-, 5-, 7-, and 10-year basis and at 5-year intervals thereafter until the next cutting period.

Data are visually compared to previously collected data. Accuracy assessments are completed after each data-collection period. Permanent employee continually supervises temporary employees.
Raw: stand structure and grade, species, d.b.h., and number of stems available on DG. 
Species, d.b.h., And number of stems are in hardcopy. Data are downloaded to PCs for analyses.
