Habitat
This shrew inhabits the tundra and boreal forests of northern Alaska and Canada, favoring moist areas like stream banks, wet meadows, and under vegetation. It thrives in cold, subarctic environments with abundant cover and prey. These regions provide the necessary insulation and food sources for survival.
Diet
The Barren ground shrew primarily eats insects, earthworms, spiders, and other small invertebrates. It forages actively day and night, using its sensitive snout to detect prey in soil and leaf litter. Due to its high metabolism, it must consume food equivalent to its body weight daily.
Behavior
Barren ground shrews are solitary and territorial, marking their areas with scent and vocalizations to deter intruders. They are primarily nocturnal, spending days in burrows or under debris, and exhibit high activity levels to meet their energy needs. These shrews are known for their rapid movements and aggressive interactions when defending territory.
Conservation Status
The IUCN status is Least Concern, with a stable population trend due to its wide distribution. Major threats include habitat degradation from climate change and potential predation pressure.
