Catalog of Long Term Research Conducted by the Northeastern Research Station

Catalog #8

Range-Wide Sugar Maple Provenance Study
1) To determine the nature and extent of genetic variation within and between provenances throughout the range of sugar maple. 
2) To compare juvenile and mature performance within provenances.

Fernow Experimental Forest
on Fork Mountain ~200' southwest of the NE corner of the Fernow. 
lat, long, and elev.(feet) are documented for each provenance. 
Soils: DeKalb Channery loam 
Slight easterly aspect with slope of 5-15%.
Prior to clearcut of 1968, there was an oak site index of 70 and was occupied by second growth hardwoods with red oak, yellow poplar, sugar maple, black birch, white ash, and others.
Randomized block design with the long dimension parallel with the contour contiguously replicated 5 times. 
14 provenances, each represented by 7 or 8 parent trees were randomly planted (in 2-tree plots) in each block. Trees were spaced 5' X 5'.

14 Sugar Maple seed sources were planted in 5 contiguous replications. 224 Trees were planted in each of the 5 replications.

Clearcut 1968: sawlogs and pulpwood were skidded from the area. Area is ~1.5 acres (700' long by 100' wide) was prepared for planting using mulch. Trees were planted in 1968. Following planting, each tree was mulched with a 2.5' square of 6-mil black plastic. A screen cylinder made of 1/4" hardware cloth, 6" in diameter and 18" high, was placed around each tree 1968 to protect the stems from rodents.
Auger was used with a 12" diameter bit during planting. Total height is the distance between ground surface and tip of dominant leader.
Independent: Provenance, parent.

Dependent: filled seed, dry seed weight, seedling mortality, diameter growth, height growth, forking, crown size, onset and break dormancy, photoperiodic response, cold injury, drought and heat damage, sap sugar content, wood properties.

Seedling survival: 2 months, 1968, 1969, 1970, 1971, 1972, 1974. 
Stem height and stem diameter (1" above root collar): 1970, 1971.
Survival and height: 1971, 1972, 1974, 1994. 
Sap sugar measurements - replications 1 & 5: 1975, 1976. 
All replications: 1977, 1978. 
Total height, stem diameter, and survival: 1982, 1994.

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.
