Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Ctenomys sociabilis faces severe threats from agricultural expansion and livestock grazing that directly destroy its specialized grassland habitat. The species' extremely restricted range in Argentina's Pampas region makes it particularly vulnerable to habitat conversion, while its colonial social structure means that local population losses can have disproportionate impacts on the species' survival.

Threat summary

Habitat

This colonial tuco-tuco inhabits short grasslands and prairie areas in the Pampas region of Argentina, where it constructs extensive underground burrow systems. The species requires well-drained soils suitable for excavation and open grassland areas that support its specialized feeding and social behaviors.
