Region Overview

The Lower Athabasca Region encompasses an area of 93,212 km2 or 14% of the province in northeastern Alberta. This region largely overlaps the Central Mixedwood Natural Subregion, which is characterized by a mix of Trembling Aspen dominated deciduous forests, Trembling Aspen-White Spruce mixedwood forests, and White Spruce-Jack Pine coniferous stands in the uplands, and wet, poorly drained fens and bogs in lowland areas. Energy development in the Athabasca and Cold Lake Oil Sands Areas and forestry are the two dominant land use activities. These land uses along with mineral extraction, agriculture, and tourism, have led to an increase in human disturbance across the landbase. Human footprint status and trends are summarized for the Lower Athabasca Region.

Status

As of 2023, human footprint occupied in the Lower Athabasca Region.

Agriculture (2.9%), forestry (2.8%), and energy (2.3%) footprints covered similar areas. The remaining footprint types each covered < 1.0% of the region.

Human Footprint Type Area (km2) Area (%)
Due to rounding errors and/or small amounts of human footprint that cannot currently be assigned to a reporting category, the sum of the individual human footprint reporting categories may not equal the total human footprint value.

Trend

  • Between 2000 and 2023, the total area of human footprint in the Lower Athabasca Region
  • This increase in human footprint was driven by the expansion of the forestry footprint, which increased by 1.5 percentage points, from 1.3% to 2.8%. This increase in forestry footprint is lower when forest recovery is considered: forestry footprint increased by 0.8 percentage points (1.2% to 2.0) when recovery of regenerating forest is included.
  • The increase in energy footprint was similar at 1.2 percentage points, from 1.2% to 2.3%. The remaining human footprint categories each had increases of < 1.0 percentage point between 2000 and 2023.

Status of Linear Human Footprint

  • Density of linear features was in the Lower Athabasca Region.
  • Legacy seismic lines, with a density of 0.5 km/km2, were the predominant line type, representing 37% of linear footprint in the region.
  • Density of roads (0.4 km/km2) and other linear features (0.3 km/km2) combined represented 51% of linear footprint in the Lower Athabasca Region.
  • Transmission lines and railways had very low densities in the Lower Athabasca Region.

Please note that linear density reporting excludes seismic line types that are not consistently represented provincially, including: Seismic Line of Sight, Low Impact Seismic, Seismic Conventional (Modern), Seismic Avoidance, and unconfirmed seismic lines.
