Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01

Geographic Range [top]

Range Description:Augastes lumachella is restricted to Bahia, between Morro do Chapéu, Andarái and Barra da Estiva, north-east Brazil, at elevations of 950-1,600 m (Sick 1993, Parker et al. 1996) where it is fairly common but its restricted range renders it vulnerable to any form of disturbance (Sick 1993, Parker et al. 1996).

Population [top]

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

Trend Justification:  The population is suspected to be stable in the absence of evidence for any declines.
Current Population Trend:Stable
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in areas of arid and semi-arid montane scrub (campo rupestre) that are rich in cacti, bromeliads, Velloziaceae and orchids.

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):4.2
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Much of its range was colonised when diamonds and gold were found in the region in the 19th century, and small operations persist. Quartz crystals and manganese are also mined. The principal threat is now increasing conversion of land for cattle ranching (Stattersfield et al. 1998).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II.

Conservation Actions Proposed
Study its ecology and attempt to obtain an accurate estimate of its population size and trends. Quantify extent of habitat losses. Protect areas of suitable habitat and safeguard against clearance and encroachment.
