The species has a low reproductive rate with gestation greater than two months and usually only 1-2 young (Kraus and Rodel 2004). Reproduction is seasonal (Kraus et al. 2005).
IUCN Red List Assessment
Red List Category
Red List Criteria
Gonzalez, E. & Lessa, E.
Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Least Concern because its extent of occurrence is much greater than 20,000 km², it has a presumed large population, and although there are some declines occurring in Uruguay, these are not significant enough for it to be considered for listing in a more threatened category.
- 1996Lower Risk/least concern
There is no information on population or abundance, but the species is adaptable to grasslands and is assumed to have a stable population.
Intentional burning of vegetation for cattle ranching is a major threat.
The species occurs at least in one protected area in Uruguay (Laguna de Castillos) and at least four in Brazil. Further taxonomic studies of this species are required.
