Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2009-12-10
Assessor/s: Abba, A.M. & Superina, M.
Reviewer/s: Bolkovic, M.L. & Gonzalez, E.
Justification:
Dasypus hybridus is listed as Near Threatened as it is believed to have undergone a decline in the order of 20?25% over the past 10 years due to severe habitat loss and hunting throughout its range. The species was previously more widespread and locally more common (over 30 years ago). It almost qualifies as threatened under criterion A2cd.
History:
2006 Near Threatened (IUCN 2006)
2006 Near Threatened

Geographic Range [top]

Range Description: D. hybridus is found in Argentina, Uruguay, Paraguay, and southern Brazil. It occurs as far south as the province of Buenos Aires, Argentina (Abba 2008). The distribution is more restricted than depicted by Redford and Eisenberg (1992) and Wetzel (1985). Localities in the west near the Andes are based on incorrectly identified individuals. In the province of Córdoba, Argentina, it is restricted to the east. The exact northern limit of its range is uncertain due to its morphological similarity to Dasypus septemcinctus.

Population [top]

Population: D. hybridus was previously common (although there are no population density estimates available), but it is sensitive to habitat loss through urbanization, and agricultural expansion has meant that populations are declining or absent over much of its former range (Abba et al. 2007). It remains a common species in parts of its range (e.g. the province of Buenos Aires, Abba 2008).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This armadillo species is typically found in the grasslands and pampas of northern and central Argentina (Abba et al. 2007, Abba 2008, Abba and Cassini 2008). It is also present, but less common, in woodland and forest habitats.
Systems: Terrestrial

Threats [top]

Major Threat(s): D. hybridus is threatened by habitat loss through agriculture, urbanization, accidental mortality on roads, direct hunting for food and predation by dogs (Abba et al. 2007, Abba 2008).

Conservation Actions [top]

Conservation Actions: D. hybridus has been recorded in a few protected areas. It is considered a conservation priority species in Uruguay (E. Gonzalez pers. comm. 2010).
