Reviewer(s): Duckworth, J.W. (Small Carnivore Red List Authority) & Schipper, J. (Global Mammal Assessment Team)

This species is listed as Least Concern as the species is widespread and apparently common in an area of relatively intact habitat, population density varies greatly from region to region and there are no major threats (although the species is probably declining due to hunting and habitat loss).
History:
1996 Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: Nasua nasua is broadly distributed in South America, ranging from Colombia and Venezuela in the north to Uruguay and northern Argentina in the south (Gompper and Decker, 1998).

Population [top]

Population: Population density of Nasua nasua varies greatly from region to region. Densities reported ranges from 6.2 individuals/km2 in a region of low-lying deciduous forest, to 13 individuals/km2 in taller gallery forests (Gompper and Decker, 1998).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species is an occupant of forested habitat. It has been reported from multistratal deciduous and evergreen rainforest, riverine gallery forest, xeric chaco, cerrado and dry scrub forest (Brooks, 1993; Emmons, 1990; Handley, 1976; Mondolfi, 1976; Schaller, 1983). It is found over a wide altitudinal range, with Andean individuals found at elevations up to 2,500 m (Lönnberg, 1921). Nasua nasua is omnivorous, eating predominantly invertebrates and fruit (Gompper and Decker, 1998). The consumption of vertebrates has been noted, but is never common (Beisiegel, 2001; Bisbal, 1986; Gompper, 1996; Kaufmann, 1962; Russell, 1982; Schaller, 1983). It is essentially diurnal in its activities. Adult males are solitary, while females and immature males travel in groups up to 30 individuals (Crespo, 1982; Emmons, 1990; Schaller, 1983).
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss due to deforestation and hunting for their meat by natives are major threats for the species.

Conservation Actions [top]

Conservation Actions: This species is protected under CITES Appendix III as N. n. solitaria in Uruguay. The species occurs in numerous protected areas.
