Georgia Growth and Yield Study
1) To study upland oak in its southernmost range. 
2) To demonstrate the proper techniques in thinning southern Appalachian hardwoods. 
3) To demonstrate real world tests of existing growth and yield predictors.
Chattahoochie National Forest, Brasstown Ranger District, near Blairsville, GA. Area is representative of the lower Piedmont mountain chain of GA. Stands are uneven-age oak hickory forest type.
17 0.5-acre circular plots located in 2 compartments; 12 are treated plots and 5 are control plots. Within each compartment, all plots were selected to be as identical as possible in specie composition and physiographic features.
Stands were thinned to approximately 60 square feet of basal area per acre. Identification numbers were stapled on the trees. Each plot was photographed from all 4 cardinal points before thinning: 1979.
Models developed from other plots are used to predict growth. Remeasurement at 5-year intervals will check accuracy of the predictions.
Height, growth, diameter growth, cubic foot volume, board foot volume, and stand development.
Practices Field data are verified when entered into computer. Field crews were trained by experienced field personnel.
Available data are maintained in an ORACLE database (SASQUATCH) according to the following categories: study description, stand density plot data, plot history, plot summaries, ingrowth summaries, plot treatments, species descriptions, ecological data, size of opening data. Hardcopy of some tally sheets are maintained in file cabinets.
