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.
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.
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.
Figure: Local Scale Effects. Predicted changes to Pinus contorta relative abundance inside areas that have been disturbed by each sector (human footprint type) compared to the habitat it replaced (modelled reference condition with no human footprint). Sector effect values less than 0% indicate habitat suitability is reduced (predicted related abundance is lower) compared to reference conditions, and values more than 0% indicate habitat suitability is improved (predicted relative abundance is higher) compared to reference conditions.
Figure: Regional Population Effects. Predicted change in the total regional population by industrial sector for Pinus contorta. This incorporates the area of the footprint, the native habitats where the footprint occurs, and the species response to a particular footprint. Regional population effect values less than 0% indicate a predicted decrease in the regional population due to a particular sector’s footprint, and values greater than 0% indicate a predicted increase.
The current condition is the predicted relative abundance of Pinus contorta taking current human footprint (circa 2018) into account.

The reference condition shows the predicted relative abundance of Pinus contorta after all human footprint had been backfilled based on native vegetation in the surrounding area.
The difference map shows areas where the current relative abundance of Pinus contorta 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.
