Study of Partial Cuttings of Sawlogs on Bear Tree Plots
1) To determine the response of the chief species of species groups in the residual stand in terms of growth in diameter and yield in volume. 
2) To determine the loss of growing stock due to logging and natural mortality following cutting. 
3) To determine the amount, species and quality of ingrowth of sapling regeneration following sawlog cuttings.
1933
expected to continue
Northwest corner of compartment 19 on Kane Experimental Forest - Elk County, PA. Stands are a mixture of beech-birch-maple-cherry which had followed clearcutting. When treated in 1933, the stands were about 40 years old with a few holdover beech and hemlock ranging from 80 to 190 years old.
2 1-acre plots (plot 1 and plot 2) were divided in half (0.5-acre subplot was thinned, 0.5-acre was not cut). 1 2-acre plot (plot 3) was divided into 4 0.5-acre subplots (2 0.5-acre subplots were thinned, 2 0.5-acre subplots were not cut). 2 large plots (12 acres and 8 acres) were used as natural, untreated control areas for the study. The 2-acre block #3 was removed from the study during 1980.
100%
Plots were thinned in 1933 and 1954: some areas were thinned during both years.
Original study complete yet measurements continue to be taken. In 1978, 100% inventory was made on all unnumbered trees. In 1982, plots were renumbered for organizational purposes.
Species, tree number, diameter, height, crown class: 1933, 1938, 1943, 1948, 1953, 1959, 1964, 1978, 1984 (crown class replaced by frequency during 1984). 
Tree age and condition:1933. 
Tree vigor and quality: 1953.
Tally of all trees >1": 1959, 1964.
Data visually checked during computer entry.
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.
