Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-12-09
Assessor/s: Abba, A.M. Superina, M.
Reviewer/s: Bolkovic, M.L. & Poljak, S.
Justification:
Chaetophractus 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 more threatened category.
History:
2006 Least Concern (IUCN 2006)
2006 Least Concern

Geographic Range [top]

Range Description: C. villosus is present in the Gran Chaco of Bolivia, Paraguay, and Argentina as far south as Santa Cruz, Argentina and Magallanes, Chile (Gardner 2005). 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).

Population Trend: Increasing

Habitat and Ecology [top]

Habitat and Ecology: C. villosus is present in a wide variety of habitats, among them grasslands (including pampas and chaco), savanna, and forest. It is also found in cultivated landscapes (Abba et al. 2005, Abba et al. 2007, Abba 2008).
Systems: Terrestrial

Threats [top]

Major Threat(s): In some parts of its range, C. villosus is locally used for food and charangos (musical instruments; Aguiar and Fonseca 2008). It is also persecuted as a pest species in agricultural areas, and is subject to sport hunting. Animals may also be killed on roads and by dogs (Abba et al. 2007, Abba 2008).

Conservation Actions [top]

Conservation Actions: This species is present in many protected areas.
