Region Overview

The Foothills Natural Region, located on the eastern flank of the Rocky Mountains, covers approximately 66,000 km2 or 10% of the province. Characterized by variable terrain and a moist, cool climate, the lower slopes consist of rolling hills and plateaus with of mixture of grassland, deciduous, and mixedwood forests. At higher elevations, slopes become steeper and conifer forests predominate. Streams with headwaters originating in the Rocky Mountains frequently bisect the landscape. As a transitional ecosystem between the Rocky Mountain Natural Region to the west and the Grassland and Boreal Natural Regions to the east and north, biodiversity in the foothills is generally a mix of these surrounding regions. Human footprint is presented for the Foothills Natural Region.

Status

As of 2021, human footprint occupied 33.6% of the Foothills Natural Region. Forestry was the dominant human footprint, covering 24.3% of the region, followed by agriculture footprint (3.3%), energy footprint (3.0%), and transportation footprint (2.0%). The remaining footprint types each covered < 1.0% of the region.

Trend

  • Between 2000 and 2021, the total area of human footprint in the Foothills Natural Region increased by 14.2 percentage points, from 19.4% to 33.6%. 
  • Almost all of this increase can be attributed to the expansion of forestry footprint, which increased by 13.0 percentage points, more than doubling in size during this time from 11.3% to 24.3%. However, this increase in forestry footprint is lower when forest recovery is considered: forestry footprint increased by 8.5 percentage points, from 9.4% to 17.9%, when recovery of regenerating forest is included.
  • The remaining human footprint categories all had small increases of < 1.0 percentage point between 2000 and 2021, with energy footprint showing the next largest increase from 2.2% to 3.0%.

Status of Linear Human Footprint

  • Density of linear features was 4.2 km/km2 in the Foothills Natural Region.
  • Conventional seismic lines, with a density of 2.7 km/km2, were the predominant linear feature, representing 64.3% of linear footprint in the region.
  • Density of pipelines (0.7 km/km2) and roads (0.8 km/km2) combined represented 35.7% of all linear footprint in the Foothills Natural Region.
  • Transmission lines and railways had very low densities.
