| Title: |
Compartment Managed Group
Selection Study
|
| Objective: |
To study the development of a stand following clear cutting
in small patches. |
| Year Established: |
1936 |
| Year Completed: |
expected to continue |
| Site Description: |
Bartlett Experimental Forest. Compartments contained typical
old-growth northern hardwoods during 1931-1940. |
| Statistical Design: |
2 adjacent compartments (#5 and #6) on Bartlett Experimental
Forest. |
| Likelihood of Locating Study Areas: |
80% |
| Experimental Treatments: |
Cut:
11.2 acres total (32 groups of 0.35 acres): 1937-1940.
18.0 acres total (39 groups of 0.5 acres): 1951.
9.1 acres total (13 groups of 0.7 acres): 1960.
: 1975.
: 1992.
For all cuts, all hardwoods >1.6" d.b.h. were cut. All softwoods
<4.0" d.b.h. and a few of the better formed 4" to 6" d.b.h.
Were left uncut. Cuttings were centered around clusters of old
trees. |
| Sampling Methods: |
varies |
| Variables and Sampling Frequency: |
Basal area, d.b.h." by class and species, species composition,
stocking and structure: 1937 1951, 1960, 1992. |
| QA/QC Practices: |
|
| Data Storage: |
Data on tally sheets. Summaries on paper. |
| Global Change Research Applications: |
