Catalog of Long Term Research Conducted by the Northeastern Research Station

Catalog #6

Black Walnut Seed Orchard/Progeny Test for National Forests in the Eastern Region
1) To evaluate growth and survival of black walnut collection from 34 families.
2) To produce genetically-improved walnut seed suited to growing in conditions on the Shawnee, Hoosier, Wayne, and Monongalia National Forests.
1976
expected to continue
4 blocks above Hickman flat and 2 blocks in old growing stock level study area south of McGowan Mountain Road in the Fernow Experimental Forest. 
Both areas were previously forested with 65- to 70-year old stands of mixed Appalachian hardwoods including a high proportion of black cherry, yellow-poplar, red oak, sugar maple, and white oak. 
Latitude, longitude, state and county are listed for each parent tree. Soils on Hickman flat are mapped as Belmont silt loam, a limestone soil derived from the Greenbrier limestone formation. Soil on McGowan Mtn. site is mapped as Meckesville silt loam which has some limestone influence since soil is found below Belmont. Oak site index os 80 to 85. 

Hickman: elevation 2560', N39deg 02min 02sec, W79deg 41min 08sec. 
McGowan: elevation 2720', N39deg 03min 30 sec, W79deg 39min 17sec.

Random Block Design. 6 blocks, 5-tree plots, 34 tree families.
100%
Sawtimber and pulpwood were harvested and all remaining stems were felled. The brush and small stems were pulled from the area by winching with a tractor from the perimeter of the area. 
Tree seedlings were gathered from 34 black walnut families and planted in a spacing of 6' apart in rows 12-feet apart (rows with long dimension of the plot): 1976. 
Cut vegetation overtopping seedlings: 1976. 
Herbaceous vegetation treated with Simazine: 1977. 
Woody vegetation cut with a Hoffco brushcutter: 1977-1978, 1979, 1980, 1982. 
Herbaceous vegetation and hardwood sprouts were treated with Roundup herbicide: 1983. 
Competing woody vegetation and grapevine were cut: 1987, 1989.
Auger was used to drill holes to plant seedlings. Seedling height measured to the nearest 0.05' and stem diameter at ground level was measured to the nearest 0.05 cm.
Independent: growth height and diameter, survival.

Dependent: Black walnut families.
5th year remeasurement 1981.
15 year remeasurement 1991. 
Survival and total seedling heights tallied 1976. 
Height 1977, 1978, 1979, 1980. 
Height, stem diameter at root collar, d.b.h. 1982. 
Height, d.b.h., quality remarks 1989, 1991.

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.
