| Title: |
Timber Management Units
|
| Objective: |
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). |
| Year Established: |
1951 |
| Year Completed: |
expected to continue |
| Site Description: |
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. |
| Statistical Design: |
Randomized design. |
| Likelihood of Locating Study Areas: |
100% |
| Experimental Treatments: |
Extensive selective improvement operations to maintain a state
of readiness for future research. |
| Sampling Methods: |
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.+;
Mortality and its cause (spruce budworm, uproot, breakage, suppression,
other). |
| QA/QC Practices: |
Visual check of raw data and the use of error-checking computer
programs. Field check plots were maintained. |
| Data Storage: |
~5 mbytes on PC, paper, and diskettes. |
| Global Change Research Applications: |
Studies of Ecosystem Processes |
