The Effect of Deer Fencing Erected After Clearcutting on Allegheny Hardwood Reproduction
To determine the effect of fencing erected shortly after clearcutting on the development of tree reproduction in the cut areas.
1970
1972
Allegheny National Forest. Forest Type is Cherry-Maple. Sites are located in: Ridgway District - Elk Co., Bradford District - McKean Co., Sheffield District - Warren Co.,
18 fenced areas (enclosures):10 in recently clear-cut stands (*),3 in older clear-cutstands(**),2 in partially cut stands (***), and 3 in uncut stands (****).

A cluster of 9 6'-radius, 0.002-acre, sample plots were located inside and outside of each exclosure. The sample plots are arranged in 3 rows of 3 plots each, with 40 feet between plots. The center plot of the outside cluster is located at least 100' from the fence to avoid atypical conditions that sometimes exist in the heavily traveled zone near the fence perimeter.

100%
The 0.002-acre plots are permanently marked. Fences erected 1972. Stands were previously clear-cut during 1957 thru 1966.
Trees are recorded by species and height class, and the exact height of the tallest individual of each important species was recorded. Statistical comparisons among fenced and unfenced plots are made using the Student's "t" test for paired observations. A range of criteria are used to evaluate probable future stocking densities of the plots.
Dependent: 
Number of stems of woody species, by species and height class. 
Species and density of ground cover vegetation. 
Species of the tallest stem on the plot. 
Height (to 0.1') of the tallest black cherry, sugar maple, red maple, white ash, other desirable species, and other commercial species. Indication of whether or not each of the stems (of species listed above) are "free-to-grow".
100% Inventory: species, d.b.h., frequency: 1977, 1982, 1988.
Data are proofed after field collection and data entry. Data collection supervised by permanent employees.
Raw data by plot reside on DG and tally sheets are kept with written instructions and detailed maps to each stand. 
Annually, the raw data are transformed using the REGEN1 program in DG Info. System. Summarized data by plot and by stand reside in a DG-based program that can output to ASCII text files.
