Synopsis: The purpose of this model is to indicate potential habitat for olive-backed pocket mice (Perohnathus fasciatus) within the Milk River Basin. As this is a landscape level model with course variaqbles, it may not be directly applicable to other areas for site-specific analysis. Conclusions: Olive-backed pocket mice require high proportions of grassland habitat and low proportions of shrub cover. Sites with low densities of shrubs are preferred because they provide cover from large and aerial predators, such as owls. A threshold of below 40% shrub coverage represents ideal shrub cover proportions.

Synopsis: This report evaluates habitat requirements of the American badger according to parameters of soil texture, graminoid cover, slope, and proximity to roads. Badgers tend to prefer sandy loam and silty loam, medium and moderately coarse textured soils. In terms of graminoid coverage, badgers generally prefer open grassland habitat, but can also be found in agriculturally dominated landscapes containing isolated pockets of Richardson 's ground squirrel colonies. Graminoid coverage of 23% was chosen as the minimum requirement for suitable badger habitat. As slope increases, habitat suitability decreases to a point at which the likelihood of badgers existing there (i.e. cliffs and badlands) is extremely low...

Conclusions: Richardson's ground squirrels prefer short grass native prairie / pasture but can also occupy small isolated islands within cropland. These squirrels prefer open prairies and tend to select against heavily forested areas. *Note that this study generated landscape level models with coarse variables, and the thresholds and values used may not be directly applicable to other areas or for site-specific analysis. Thresholds/Learnings: A threshold amount of 20% graminoid coverage is the minimum suitable proportion for habitat suitability for Richarson's ground squirrel. Areas with less than 20% forest/shrub cover were considered sutiable habitat, while those greater than 40% were considered unsuitable*. ...

Synopsis: The short-horned lizard is Alberta's only lizard. It is indigenous to semi-arid, short grass portions of the northern Great Plains and usually found in rather rough terrain. This report evaluated habitat suitability requirements for the short-horned lizard according to the following parameters: Topographical Features: Most of the daily movement patterns during the summer rarely exceeded 30m, and generally occurred along the slopes of the valleys or valley bottoms. Consequently, all valleys and all prairie habitat within 100m of valleys are considered the best potential habitat. Native Prairie Class: Native Prairie Class (NPC) is derived from the Native Prairie Vegetation Baseline Inventory developed...

Synopsis: This model is based around Native Prairie Cover types, and Soil Texture. Native Prairie Class (NPC) is derived from the Native Prairie Vegetation Baseline Inventory developed by AlbertaEnvironment. Class I is comprised of greater than 75% native prairie components (i.e. shrubs, graminoids, riparian areas, lakes, wetlands, and trees), Class 2 is 50 - 75%, Class 3 is 25 - 50%, Class 4 is 1 - 25%, and Class 5 is no native prairie components. Native prairie is probably the most important and limiting factor for ferruginous hawks. Although hawks have been found in areas that were primarily under cultivation), they were in close proximity to prairie in good condition. Overall NPC was selected over its individual...

Conclusions: Areas for roosting are likely the most limiting factor for the Western Small-footed Myotis. Unlike various other bats, this myotis does not roost in trees, but rather under rocks, and in holes and crevices found in rock outcrops within cliffs and coulees. Summer roosts can be found in cavities within cliffs, boulders, vertical banks, the ground, and talus slopes. Distance to water was also a significant factor affecting habitat suitability Thresholds/Learnings: Habitat for western small-footed myotis bats is ideally located within 1000m of water. Habitat located >3000m from water is deemed unsuitable. Synopsis: Areas for roosting are likely the most limiting factor for the Western Small-footed Myotis....
