Catalog of Long Term Research Conducted by the Northeastern Research Station

Catalog #7

Genotypic Variation in White Ash
To evaluate growth and survival of white ash collected from 45 geographic sources.
expected to continue
Fernow Experimental Forest 
McGowan Mtn. Rd. ~1/2 mile south of junction with the Main Fernow Loop Rd. 
lat: N39deg 02min 02sec, long: W79deg 41min 08sec. latitude, longitude, and elevation (feet) is documented for each seedling source. 
Soil is mapped as Mechesville silt loam with limestone influence. 8-15% slope. 
Elevation: ~2720'. 
Planted 10 X 10 spacing 5-tree plots.
Cleared 8.5 acres of previously 70-yr old mixed hardwoods including black cherry, northern red oak, yellow poplar, sugar maple, and white ash.
Random Block Design. 5 blocks, 5-tree plots, 45 families.
Trees were planted using Auger during 1979. Corners of all blocks were marked with 4-foot long 5/8" iron rod and a brass numbered mine check was placed next to the 1st tree in each 5-tree plot with a #9 wire pin: 1976.
Release of seedlings with Hoffco MP 670 brush cutter: 1977, 1978, 1980, 1982.
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 growth to nearest 0.05', and diameter growth at ground level to nearest 0.05cm., survival, disease and insect incidence. 
Survival and total seedling heights 1976. 
Survival and total height after 2,3,4,5 years (1977,1978,1979, 1980) and at 5 year intervals thereafter.

Dependent: White ash geographic source (12 states).
Total height, diameter at 1" above ground, and d.b.h. on trees >4.5' tall.

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.
