Hilt's Control Plots
||To determine weather effects on growth and yield of mature
||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
|Likelihood of Locating Study Areas:
||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).
|Variables and Sampling Frequency:
||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.
|Global Change Research Applications:
||Studies of Ecosystem Processes
|Publications and Reports:
||none to date
