Compartment Managed Selection System Study
To provide financial and silvicultural capabilities of different silvicultural management programs.
Topography is gentle to moderately steep with a northerly aspect.
Uneven-age, old-growth northern hardwood forest covering 277 acres.
4 management programs on six compartments.
Selection cut to remove 40 square feet per acre which yielded 7 cords per acre. 
Selection cut to remove 20 square feet per acre which yielded 5 cords per acre. 
4 management programs applied to 6 compartments in areas usually <1 acre in size: 
    1) Liquidation - removal of trees >8" d.b.h. 
    2) Diameter limit cut - removal of trees < 13" d.b.h. 
    3) Single-tree selection cut. 
    4) Patch cut - removal of vegetation >2" d.b.h.

100% initial inventories were taken of the growing stock on each compartment prior to the first harvest cuts (0.5" or larger, by 2" d.b.h. classes). 
Prior to cutting , all marked trees were tallied by d.b.h. class and grade, and a post-logging compliance check was made after each cut (1952, 1953, 1972, 1976).
Record keeping manuals were followed.
data on tally sheets. summarized on paper.
