| Title: |
Compartment Managed Selection
System Study
|
| Objective: |
To provide financial and silvicultural capabilities of different
silvicultural management programs. |
| Year Established: |
1952 |
| Year Completed: |
1975 |
| Site Description: |
Topography is gentle to moderately steep with a northerly
aspect.
Uneven-age, old-growth northern hardwood forest covering 277
acres. |
| Statistical Design: |
4 management programs on six compartments. |
| Likelihood of Locating Study Areas: |
100% |
| Experimental Treatments: |
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.

| Sampling Methods: |
|
| Variables and Sampling Frequency: |
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). |
| QA/QC Practices: |
Record keeping manuals were followed. |
| Data Storage: |
data on tally sheets. summarized on paper. |
