In this section we summarize the density of linear features in Norbord's operating areas, overall and by different linear feature types.
The density of linear footprint, circa 2018, was:
Northern Operating Area: 3.23 km/km2
Southern Operating Area: 3.43 km/km2
Density of Linear Features
Total linear footprint density, circa 2018, was found to be:
Northern Operating Area
Southern Operating Area
Partner Operating Area
- Conventional seismic lines were the predominant line type in the Northern Operating Area representing 89% of line types in the region with a density of 2.84 km/km2. The remaining line types all had low densities in the region.
- In the Southern Operating Area, conventional seismic lines, at 1.98 km/km2, were also the most common linear features representing 58.0% of line types. However, pipelines, at 0.77 km/km2, and roads (both major and minor), at 0.62 km/km2, were also common, representing 22% and 18% of linear features, respectively.
- Transmission lines and railway lines had very low densities in all three operating areas.
