Large hairy armadillo
Chaetophractus villosus

C. villosus is present in the Gran Chaco of Bolivia, Paraguay, and Argentina and as far south as Santa Cruz, Argentina and Magallanes, Chile. It has been introduced in Tierra del Fuego Province, Argentina (Poljak et al., 2007; Poljak et al., 2010). It ranges from sea level up to 1,500 m asl (Argentina).


The large hairy armadillo is present in a wide variety of grasslands (including pampas and chaco), savanna, and forest habitats. It is also found in cultivated landscapes (Abba et al., 2005; Abba et al., 2007; Abba, 2008) and some degraded habitats (arable land, pastureland, rural gardens, and plantations).


This is one of the most common armadillo species in Argentina (Abba, 2008). Males and females reach sexual maturity at one year of age, and the female gives birth to one yearly litter of one to three young. Gestation length is 68 days.


In general, there appear to be no major threats to this species. In some parts of its range it is locally used for food and charangos (Aguiar and Fonseca, 2008). It is also persecuted as a pest species in agricultural areas, and is subjected to sport hunting. Animals may also be killed on roads and by dogs (Abba et al., 2007; Abba, 2008).


C. villosus is listed as Least Concern in view of its wide distribution, presumed large population, its presence in a number of protected areas, its tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a threatened category. This species is present in many protected areas.
