Catalog of Long Term Research Conducted by the Northeastern Research Station

Catalog #30

Timber Management Units
To develop stocking and stand tables and to develop growth and yield estimates for spruce-fir dominated areas of the compartment management study (catalog# 29).
expected to continue
Penobscot Experimental Forest, Bradley, ME. USGS 15-min series topo Orono ME Quadrangle. UL: 4969400mN 528800mE or 44deg, 48min,30 sec by 68deg,34min,00sec. LR: 4961300mN 534900mE or 44deg, 52min, 45sec by 68deg, 37min, 30sec. 
The study area is predominantly northern coniferous stands with perhaps 4 specific forest types represented in any appreciable area.
Randomized design.
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.
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.+; 
Mortality and its cause (spruce budworm, uproot, breakage, suppression, other).
Visual check of raw data and the use of error-checking computer programs. Field check plots were maintained.
~5 mbytes on PC, paper, and diskettes.
