Red List Category & Criteria: Near Threatened ver 3.1

This species has narrow habitat requirements, and is likely to have a moderately small and fragmented population which may be declining owing to habitat loss. It is therefore considered Near Threatened.

Geographic Range [top]

Range Description: Limnoctites rectirostris occurs in extreme south Brazil (Santa Catarina and Rio Grande do Sul), south Uruguay and east Argentina (Entre Ríos and extreme north-east Buenos Aires) (Ridgely and Tudor 1994, Babarskas and Fraga 1998). It is very locally distributed, but locally common in appropriate habitats.

Population [top]

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

Habitat and Ecology [top]

Habitat and Ecology: This species occurs up to 1,100 m, in small marshes and swales, as well as short trees and shrubs bordering wet areas. It is closely associated with the spiny apiaceous herb "caraguata" Eryngium spp., which is abundant in marshes throughout its range (Ridgely and Tudor 1994). It also occurs locally away from water in upland thickets of Epyngium pandanifolum.

Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): In Argentina, and particularly in the heavily populated Buenos Aires province, its habitat is threatened by house-building, rubbish dumps and water pollution (Chebez 1994). It is presumably also threatened by intensive grazing, marsh drainage, extensive willow Salix plantations and, particularly in east Entre Ríos, the drying effects of Eucalyptus and Pinus spp. plantations (Pearman and Abadie 1995).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Conservation Actions Proposed
Repeat surveys of known sites in order to determine rates of population decline and range contraction. Encourage the conservation of wetland habitats within the range, including the gazetting of protected areas at key sites.
