Habitat
This species inhabits montane forests in the Usambara Mountains of northeastern Tanzania, preferring moist, dense undergrowth and areas with leaf litter. It is typically found at elevations between 1,000 and 2,000 meters, avoiding open or disturbed areas.
Diet
The Usambara shrew primarily eats insects such as beetles and ants, as well as earthworms and other small invertebrates. It forages actively at night, using its keen sense of smell to locate prey in leaf litter and soil. Feeding behavior is opportunistic, with multiple small meals throughout the night.
Behavior
Usambara shrews are solitary and nocturnal, spending daylight hours hidden in burrows or under logs to avoid predators. They exhibit territorial behavior, marking their ranges with scent and engaging in aggressive chases if intruders are detected. They are highly active foragers, covering significant ground each night in search of food.
Conservation Status
The IUCN status of the Usambara shrew is Vulnerable, with population trends declining due to habitat loss from deforestation and agricultural expansion. Major threats include fragmentation of montane forests and climate change impacts.
