Cipó Canastero Asthenes luizae is currently classified as Vulnerable under criterion B1 of the IUCN Red List because it was suspected to have a small and declining range.
The species was discovered in 1985 from a tiny area just north-east of Jaboticatubas within the Serra do Cipó, Minas Gerais, Brazil. However, it has since been shown to occupy a larger range and is now known from at least 15 localities (Vasconcelos and D’Angelo Neto 2007). The area of ‘campos rupestres’ where the species occurs in the Espinhaço Range in Minas Gerais is estimated at 10,000 km2. While there may be gradual encroachment on the periphery, this habitat is largely restricted to remote montane areas which afford a degree of protection. The species is relatively common in suitable habitat and a revised estimate places the population in the order of 100,000 individuals (M. Vasconcelos in litt. 2007). While its range remains below the threshold for listing the species as Vulnerable under B1, the fact that it is now known from 15 or more locations and that habitat is relatively stable suggests it warrants downlisting to Near Threatened, which would be consistent with species that occupy similar ranges and habitat within south-east Brazil.
Comments on this proposed reassessment are welcomed.
