Assessor/s:

BirdLife International

Reviewer/s:

Butchart, S. & Symes, A.

Contributor/s:

Chebez, J.

Justification:
This species is considered Near Threatened, as it is suspected to be declining moderately rapidly owing to the loss of its highly specialised habitats through deforestation.

History:

2008	–	Near Threatened
2004	–	Near Threatened
1988	–	Near Threatened

Geographic Range [top]

Range Description:	Leptasthenura setaria inhabits southern temperate and secondary forests of south-east Brazil (south Rio de Janeiro to north Rio Grande do Sul) and north-east Argentina (Misiones).
Countries:	Native: Argentina; Brazil

Population [top]

Population:	The global population size has not been quantified, but this species is described as 'common' (Stotz et al. (1996).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This species occurs in temperate and secondary forests at 750-1,900 m (Ridgely and Tudor 1994, Parker et al. 1996). It is entirely dependent upon, and relatively common in, stands of Araucaria angustifolia, even occurring in commercially planted groves around buildings and in gardens (Ridgely and Tudor 1994, J. C. Chebez in litt. 1999). The overall population in commercial plantations in Argentina appears to be large (>7,000 birds), suggesting that such Araucaria plantations play an important role in the conservation of this species (Cabanne et al. 2007).

Threats [top]

Major Threat(s):	It is threatened by the destruction of Araucaria forest, which in the state of Paraná, Brazil, alone was reduced from an estimated original cover of 73,780 km² to 15,932 km² in 1965 as a result of clearance for pastureland and cultivation (Hueck 1978, Stattersfield et al. 1998). In Misiones, afforestation with Araucaria has resulted in the species colonising new areas, but there are fluctuations in area occupied, and Araucaria plantations are now regularly replaced with Pinus (J. C. Chebez in litt. 1999).
