|Likelihood of Locating Study Areas:
||Extensive selective improvement operations to maintain a state
of readiness for future research.
||Trees > or = 4.5" d.b.h. are sampled on 0.2-acre plots. Trees
0.5" d.b.h to <4.5" d.b.h. are sampled on 0.05-acre plots.
Total of 506 acres in the treated area.
|Variables and Sampling Frequency:
||The following were collected 1951-65 and continuing before
and after treatment every 10 years thereafter.
Growth = basal area and cubic feet; condition of stand; average
d.b.h.; tree size: sapling = 0.5" d.b.h. to <4.5" d.b.h.,
merchantable = >4.5" d.b.h.+, unmerchantable = >4.5" d.b.h.+;
