Assessment Information [top]

Red List Category & Criteria: Endangered A2c+4c ver 3.1
Year Published: 2013
Date Assessed: 2010-06-02

Reviewer(s): Chanson, J.S.
Facilitator/Compiler(s): Hilton-Taylor, C.
Justification:
This species is listed as Endangered because populations have declined by at least 50% in the last three generations (generation length is 20 years) due to the conversion and degradation of its habitat by deforestation for agricultural purposes as well as mining. This trend is suspected to continue in the future.
History:
2002 Vulnerable

Population [top]

Population: The species is common in the Jequitinhonha valley but is also found in several isolated populations. Of the localities in Bahia the recent records are from 1989 and most of the records are from the 1950s to 1970s. In recent times (2010) it has only been seen in Jequitinhonha. The population trend is assumed to be decreasing as the forest where this species occurs is disappearing.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in southern caatinga (inselberg) element: in caatinga/agreste (ecotone between caatinga and forest), especially in association with gneiss/granite inselbergs or derived substrates. The generation length is around 20 years.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is used in hedges.

Threats [top]

Major Threat(s): Mining of granite soils and deforestation for agriculture (crops and cattle ranching) are the main threats to the species. The destruction of the species' habitat is likely to continue in the future as more access roads are being built and the human population in this area is increasing.

Conservation Actions [top]

Conservation Actions:  It does not occur in any protected areas. The Jequitinhonha valley is in need of conservation attention. Ex-situ conservation of the species is also recommended.
