Catalog of Long Term Research Conducted by the Northeastern Research Station

Catalog #3

Southern Appalachian White Pine Seed Source Study
1) To determine the sources of white pine that are best adapted to growing on poor hardwood sites in West Virginia (WV). 
2) To determine the possible existence and nature of genetic variation in southern Appalachian eastern white pine.
expected to continue
Location on Fernow Experimental Forest is on the lower end of Wilson Hollow Road near Parsons, WV. Soils are mapped as Calvin channery silt loam. Latitude, longitude, and county name available for seed source parent stands. 
11 acres total; 50% to 60% steep south-facing slopes having a site index of about 65 for oak.
11 acres total. Trees planted in a randomized complete block, replicated 7 times, with each seedlot represented by a 4-tree row plot. Seedlings planted at a spacing of 8' by 8' in 4-tree row plots parallel with the environmental gradient. A 2-tree wide border of undesignated WV source seedlings was planted around each of the 7 blocks.
The first tree in each source was permanently marked: 1969. 
Basal spraying using 2,4,5-T ahg. on 1.0" to 5.0" d.b.h. stems: late April 1969. 
Mistblowing to competing vegetation: Aug., 1969, Aug. 1970. 
Cutting of 1 to 5 inch d.b.h. Stems on study area that were not deadened by previous mistblowers or basal spray treatments. 
General hand mowing of the study area: Aug. 1972.
Seed from 32 stands (98 families of white pine) were obtained from Maryland, West Virginia, Tennessee, Kentucky, North Carolina, Georgia, and Virginia. Seeds were planted in 1968. 
Each surviving tree was measured in height to nearest 0.05'. Data were summarized by computing the average total height for each source and plot in each block. Two-year averages were compared to compute annual growth and four growth classes were developed to better visualize the results.
Increment cores (1977) were systematically sampled from 937 trees. Weight and radial growth measurements were made. Radial growth measurements were made using Ames dual-linear dendrochronometer.
Independent: Treatments, site class.
First year seedling mortality:1969. 
Height and survival: 1969, 1970, 1972, 1973, 1974. 
Browsing: 1969, 1970. 
Increment cores (weight and radial growth): 1977. 
Height and d.b.h.: 1977. 
d.b.h.: 1993.
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.
Studies of Ecosystem Processes
Establishment report: May 1968. 
Supplement to Establishment report: April 1971. 
Final report: 1972 Wendel, G.W. 
Progress reports: Jan. 1969, April 1969, Sept. 1969, Jan. 1970, Aug. 1970, Feb. 1971, Jan. 1972, Jan. 1973, April 1974, June 1978.
