Hilt's Control Plots
To determine weather effects on growth and yield of mature oak stands.
expected to continue
Study area is located on Mead Paper Corp. land adjacent to Vinton Furnace Experimental Forest approximately 39 deg. 12 min N lat., 82 deg. 24 min. W. long. Plots are on a ridge about 850' in elevation.
2 0.5-acre plots
control plots; no treatments.
All trees >3.6" d.b.h. on both plots were initially inventoried by species and diameter at 4.5' above the ground. Data collected are divided into two principal areas: 1) Tree Growth/Volume (represented by species, d.b.h., and crown class) and 2) Tree Grade/Quality (represented by species, d.b.h., And actual and potential tree grade).
d.b.h. to nearest 0.1": 1979, 1984, 1985, 1986, 1990, 1992. 
Crown class: 1990. 
Actual tree grade (USFS standard): 1990. 
Potential tree grade (USFS standard): 1990.
Field data are verified when entered into computer. Field crews were trained by experienced field personnel.
Only raw data collected after 1976 are available. Only summaries are available for data collected prior to 1976. 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.
