Ctenomys bergi

Declining

Overview

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

Ctenomys bergi faces severe population decline due to extensive agricultural conversion of its native grassland habitat in the Buenos Aires Province of Argentina. Urban expansion and infrastructure development have further fragmented the remaining suitable habitat patches. The species' highly specialized fossorial lifestyle and limited dispersal ability make it particularly vulnerable to habitat fragmentation, as isolated populations cannot easily recolonize disturbed areas.

Threat summary

Habitat

Berg's tuco-tuco inhabits sandy and loamy soils in temperate grasslands and pampas of eastern Buenos Aires Province, Argentina. This fossorial rodent constructs extensive underground burrow systems in well-drained soils that support native grass communities.

Ctenomys bergi is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Ctenomys bergi faces severe population decline due to extensive agricultural conversion of its native grassland habitat in the Buenos Aires Province of Argentina. Urban expansion and infrastructure development have further fragmented the remaining suitable habitat patches. The species' highly specialized fossorial lifestyle and limited dispersal ability make it particularly vulnerable to habitat fragmentation, as isolated populations cannot easily recolonize disturbed areas.
Where does Ctenomys bergi live?
Ctenomys bergi occurs in Argentina. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
