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 harvested stands 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

Sector effect graph: Changes to species relative abundance (number above or below bar) attributed to the footprint of five sectors: agriculture, forestry, energy, rural/urban footprint, and transportation. The y-axis shows the percent population change per unit area of the sector's footprint. The x-axis shows the total area occupied by each sector's footprint in the region. The areas of the sector-specific rectangle (equal to the unit effect multiplied by the area of footprint) is the total effect of the sector on the species relative abundance in the region.

Predicted Relative Abundance

Predicted Relative Abundance - Current

The current condition is the predicted relative abundance of Achillea alpina taking current human footprint (circa 2018) into account.

Predicted Relative Abundance - Reference

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

Predicted Relative Abundance - Difference

The difference map shows areas where the current relative abundance of Achillea alpina is predicted to be higher or lower compared to reference conditions. In other words, where habitat suitability is predicted to increase or decrease as a result of human footprint.
