of Long Term Research Conducted by the Northeastern Research Station
Individual Tree Selection
||To determine the effect of individual tree selection cutting
on stand growth and yield, species composition, and economics
of even-age mixed oak forests of southeastern Ohio.
||expected to continue
||Vinton Furnace Experimental Forest south of McArthur, OH.
Approximately 39 deg. 11.5 min N lat., 82 deg. 24 min. W. long.
Elevation ranges 800' to 900'. Before cutting in 1958, forest
was covered with an even-age, mixed oak type of the Central
Hardwood Forests, also referred to as the oak-hickory type.
The stands contained a relatively uniform, well stocked overstory
and a fairly dense understory. White oak, black oak, scarlet
oak, chestnut oak, post oak, and red oak comprised ~94% of the
sawtimber trees. The remainder were yellow-poplar, pitch pine,
and hickory. The most numerous species in the understory were
sourwood and dogwood, but white oak, black oak, scarlet oak,
chestnut oak, red maple, black gum, hickory, sassafras, and
other species also existed.
||Vinton Furnace Experimental Forest. 2 adjacent tracts: 1)
The selection tract is on a 21-acre minor drainage and 2) the
shelterwood tract comprises the 15.5-acre minor drainage.
|Likelihood of Locating Study Areas:
||Selection tract: 500 board ft/acre was removed: 1957, maintained
Shelterwood tract: 66% of the basal area and 50% of the net
sawtimber volume were removed: 1958.
D.b.h. measurements: 1956, 1962, 1977, 1982, 1988, 1989, 1990.
Cut to a "q" of 1.3 with max d.b.h. of 24: 1990.
|Variables and Sampling Frequency:
||For both tracts: Inventory of the overstory (pole-sized and
sawtimber trees): 1958, 1963. Inventory of reproduction (stems
per acre, frequency): 1960, 1962.
||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.
|Global Change Research Applications:
