Assessment Information

Red List Category & Criteria:

NT ver 3.1 (2001)

Year Assessed:

2006

Assessor/s:

Abba, A., Lara-Ruiz, P., Vizcaino, S. & members of the Edentate Specialist Group

Evaluator/s:

Sechrest, W. (Global Mammal Assessment) & da Fonseca, G.A.B. & members of the Edentate Specialist Group

Justification:

This species is listed as Near Threatened due to severe habitat loss and hunting throughout its range. The species was previously more widespread and locally more common (over 30 years ago). Recently, there has been a rapid observed and inferred decline.

History:

1996

Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range

Range Description:

This species is found in Argentina, Uruguay, Paraguay, and southern Brazil. It is found as far south as the province of Buenos Aires, Argentina. Recorded from Botocatu, Sao Paulo, Brazil. The distribution is more restricted than depiced by Redford and Eisenberg (1992) and Wetzel (1985). Localities in the west near the Andes are based on misidentified individuals. In the Province of Cordoba, Argentina, it restricted to the east.

Countries:

Native:

Argentina; Brazil; Paraguay; Uruguay

Population

Population:	It 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. It remains a common species in parts of its range (e.g., the Province of Buenos Aires).
Population Trend:

Habitat and Ecology

Habitat and Ecology:

It is typically found in the grasslands and pampas of northern and central Argentina. It possibly occurs in woodland and forest habitats.

System:

Terrestrial

List of Habitats:

1.5	Forest - Subtropical/Tropical Dry
3.5	Shrubland - Subtropical/Tropical Dry
4.5	Grassland - Subtropical/Tropical Dry

Threats

Threats:

This species is threatened by habitat loss through agriculture, urbanization, accidental mortality on roads, direct hunting for food and predation by dogs.

List of Threats:

1.1	Habitat Loss/Degradation - Agriculture (ongoing)
1.4.2	Habitat Loss/Degradation - Infrastructure development - Human settlement (ongoing)
2.2	Invasive alien species (directly affecting the species) - Predators (ongoing)
3.1.1	Harvesting (hunting/gathering) - Food - Subsistence use/local trade (ongoing)

Conservation Actions

Conservation Actions:

This species has been recorded from two small, protected areas at the periphery of its range. These sites need improved management. There are no protected areas in the core area of its range where the species is most common.

List of Conservation Actions:

3.2	Research actions - Population numbers and range (needed)
3.3	Research actions - Biology and Ecology (needed)
3.8	Research actions - Conservation measures (needed)
4.1	Habitat and site-based actions - Maintenance/Conservation (needed)
4.4.2	Habitat and site-based actions - Protected areas - Establishment (in place)
4.4.3	Habitat and site-based actions - Protected areas - Management (needed)
