Introduction

Over its decade-plus of operations, the ABMI has generated a comprehensive dataset on Alberta’s species, their habitats, and the extent and type of human footprint across the province. With this information, the ABMI has developed analyses to predict species' relative abundances and examine species' responses to vegetation and soil types, as well as human footprint in Alberta. These methods have been applied to hundreds of species; this profile provides summary results for one.

Habitat & Human Footprint Associations

Species-habitat Associations in the Forested Region

Forested Region - Species Habitat Association Graph: Predicted species relative abundance (bars) as a function of vegetation and human footprint type in the forested region. Dots are added to forest types where harvesting occurs and show the predicted species abundance in cutblocks of various ages. Vertical lines represent 90% confidence intervals.

Relationship to Linear Footprint


Relationship to Linear Footprint in the Forested Region

Linear Footprint Graph: Species relative abundance predicted for habitat with no human footprint compared to habitat in which 10% of the area is converted to either soft or hard linear footprint.

If it is not possible to create complex habitat association models for species, we present a coarse index of habitat use which represents the proportion of detections in each native vegetation, soil, and human footprint type in comparison to the proportional availability of the habitat types.

Habitat Associations for Species with Few Detections in the Prairie Region

Use-availability index graph: Index of species habitat use based on the proportion of species detections in each native vegetation and human footprint type in comparison to the habitat availability. The index (bars) range from -1 (avoidance) to +1 (preference), given availability of a particular vegetation or human footprint type.

Impacts of Human Footprint

Human Footprint Effects in the Forested Region

Under-footprint Sector Effects

Human Footprint Effects in the Forested Region

Figure: Under-footprint Effects. Percentage change in Carex aquatilis relative abundance inside areas that have been disturbed by each sector in the forested region. Dot above bar indicates change in abundance is greater than 100%. Refer to value above or below the bar for the estimated under-footprint effect.

To understand how the Carex aquatilis is impacted by specific development activities, the under-footprint figure shows how Carex aquatilis relative abundance is predicted to change within each sector's footprint compared to the habitat it replaced (Figure: Under-footprint Effects).

Regional Sector Effects

Human Footprint Effects in the Prairie Region

Figure: Regional Sector Effects. Percentage change in Carex aquatilis relative abundance throughout the forested region due to the respective footprints of each sector. Refer to value above or below the bar for the estimated regional effect.

The Regional Sector Effects graph shows the predicted change in the total relative abundance of the Carex aquatilis across the forested region due to each sector's footprint, considering the: area of the footprint in the region, under-footprint effect, and habitat types impacted by a particular sector (Figure: Regional Sector Effects).

Predicted Relative Abundance

Reference Conditions

  • The reference condition shows the predicted relative abundance of the Water Sedge after all human footprint had been backfilled based on native vegetation in the surrounding area.

Current Conditions

  • The current condition is the predicted relative abundance of the Water Sedge taking current human footprint (circa 2016) into account.
