White-tailed Jack Rabbit (Lepus townsendii) — Mammals (camera)

Results are based on camera traps. Therefore, only a basic summary of the data is presented.

Map of records at surveyed locations

Map of detections

The map shows survey locations (+) and detections (dots). Natural regions are shown as different background colors. Note: off-grid sites are plotted at the nearest systematic site location, and the number of detections indicated and the actual number of dots in the map might be different.

Habitat associations in northern Alberta

Habitats, North

Models were used to show how species' relative abundance differed among vegetation and human footprint types in the Boreal and Foothills regions of Alberta (see methods and manual). Models were only created for species that had at least 20 detections using data from ABMI. Predicted species abundance in each habitat type is shown with bars. Vertical lines indicate 90% confidence intervals. Dots within the forested habitat types show predicted species abundance in cutblocks of various ages.

Habitat associations in southern Alberta

Treed sites

Soils, treed, South

Models were used to show how species, relative abundance differed among soil and human footprint types in the grassland and parkland regions of Alberta (see methods and manual). Models were only created for species that had at least 20 detections using data from ABMI. Due to natural disturbances and vegetation succession, varying amounts of aspen and other trees may be present on each soil type; the presence/absence of trees greatly affects the presence and abundance of many biota. As such, information is presented twice for southern Alberta: once for sites with trees present, and onec for sites without trees present. Predicted species abundance in each soil/human footprint type is shown with bars. Vertical lines indicate 90% confidence intervals.

Non-treed sites

Soils, non-treed, South

Models were only created for species that had at least 20 detections using data from ABMI. Due to natural disturbances and vegetation succession, varying amounts of aspen and other trees may be present on each soil type; the presence/absence of trees greatly affects the presence and abundance of many biota.

Predicted relative abundance throughout Alberta under reference conditions

Map, reference

Habitat association models, plus models describing how species varied spatially and with climate gradients were used to predict species abundance in 1 km2 spatial units under reference conditions (see methods and manual). Predictions of relative abundance of the species in each 1 km2 unit were made after all human footprint in the 1 km2 unit had been 'backfilled' based on native vegetation in the surrounding area. Pixels depicted in red are predicted to have the highest abundance for the species, grading through light tan to dark blue where the species is predicted to be less abundant or absent. This figure has uncertainty due to uncertainty in the models and in the underlying vegetation map.

Predicted relative abundance throughout Alberta under current conditions

Map

Habitat association models, plus models describing how species varied spatially and with climate gradients were used to predict species abundance in 1 km2 spatial units under current conditions (see methods and manual). Predictions of relative abundance of the species in each 1 km2 unit were made based on the vegetation and human footprint present in the 1 km2 unit in 2012. Pixels depicted in red are predicted to have the highest abundance for the species, grading through light tan to dark blue where the species is predicted to be less abundant or absent. This figure has uncertainty due to uncertainty in the models and in the underlying vegetation map (see uncertainty map below).

Difference in relative abundance between current and reference conditions

Map

For each 1 km2 unit the difference between predicted current and reference conditions was determined (see methods and manual). In 1 km2 units depicted in green the species was predicted to have higher abundance under present conditions than under reference conditions, with the opposite true for 1 km2 units depicted in pink. The intensity of green and pink depict the relative magnitude of increase or decrease for the species between reference and current conditions. This figure has uncertainty due to uncertainty in the models and in the underlying vegetation map.
