Myosorex blarina
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Myosorex blarina faces severe population decline primarily due to habitat fragmentation and loss of montane forest ecosystems in its restricted range. Agricultural expansion and human settlement development have reduced available habitat corridors, isolating small populations and limiting genetic exchange. Climate change poses an additional threat by altering the cool, moist conditions this species requires in high-altitude environments.
Habitat
This small shrew inhabits montane forests and alpine grasslands at elevations between 2,000-4,000 meters in the Andes. It requires dense ground cover with leaf litter and fallen logs that provide shelter and foraging opportunities for invertebrate prey.
