Compartment Managed Group
||To study the development of a stand following clear cutting
in small patches.
||expected to continue
||Bartlett Experimental Forest. Compartments contained typical
old-growth northern hardwoods during 1931-1940.
||2 adjacent compartments (#5 and #6) on Bartlett Experimental
|Likelihood of Locating Study Areas:
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.
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
