Crop Tree Demonstration Areas
To provide several crop tree demonstration areas for a variety of stands and landowner objectives.
1989
expected to continue
1. Coopers Rock State Park, east of Morgantown, WV: 10 acres with 5 2-acre plots with 21 crop trees per acre. 
2. Camp Creek State Forest (WV). 
3. Savage River State Forest (MD): 16 year old upland oak stand (predominately northern red oak, scarlet oak, white oak, chestnut oak, red maple with black cherry, white ash, yellow poplar-cucumber) with a site index of 70 for northern red oak.
Demonstration Area, no standard statistical design for this study. Case history with untreated 2-acre plots. Treatment is based upon landowner objectives.
100%
Treatment is based upon landowner objective. Examples include crop tree release and SILVAH management (thinning to reduce basal area).
Individual tree information is monitored and evaluated as related to study treatment.
Independent: Timber, wildlife, and aesthetic and aesthetic crop tree treatments. Also, SILVAH, thinning and uncut (control) treatments.
Dependent: growth response for trees: d.b.h., total height, epicormic branches, butt-log grade. 
Remeasurement schedule post logging 2-yr, 5-yr, 10-yr, and at 5-yr intervals thereafter until next treatment.

Coopers Rock Demonstration Area only: 1988 all trees >5.0" d.b.h. were tallied by species and 2" d.b.h. class as merchantable, cull, or dead.

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.
