Simulated Mapped Plots Derived from NL Spacing Trials for Sector Subsampling Study
The base data were collected from 3 early spacing trials located in western Newfoundland, Canada and established in the early 1980s. The dominant species was balsam fir with minor components of black spruce and white birch. Five spacing treatments were applied in this study areas using a randomized...

The dominant species was balsam fir with minor components of black spruce and white birch. Five spacing treatments were applied in this study areas using a randomized complete block design: control, or no spacing, (S00), 1.2m spacing (S12), 1.8m spacing (S18), 2.4m spacing (S24) and 3.0m spacing (S30). Each treatment was repeated 3 times per site (3×3×5 = 45 PSPs in this study).

Plot sizes varied so that there were approximately 100 trees per plot following treatment.

The base data were collected from 3 early spacing trials located in western Newfoundland, Canada and established in the early 1980s. The dominant species was balsam fir with minor components of black spruce and white birch. Five spacing treatments were applied in this study areas using a randomized complete block design: control, or no spacing, (S00), 1.2m spacing (S12), 1.8m spacing (S18), 2.4m spacing (S24) and 3.0m spacing (S30). Each treatment was repeated 3 times per site (3×3×5 = 45 PSPs in this study).
