Assessment Rationale:

The species occurs at coastal and intermediate elevations on the northern laurisilva forest areas of Madeira. Seddon (2008) proposed a listing as IUCN status Least Concern (version 3.1). Although it has a restricted range, this species is present at over 20 sites in the northern part of the island and there is no evidence for declining quality of habitat. Most sites are within protected areas and hence the habitat is covered by legislation. It is recommended that the range of this species is reviewed on a regular basis.

Geographic Range:

This species is endemic to Madeira, mainly on the north side of the island, from central laurisilva forests down to the north coast between São Vicente and Porto Moniz and near Boaventura (Seddon 2008).

Habitat and Ecology

The species occurs at coastal and intermediate elevations on the northern laurisilva forest areas of Madeira.

Major Threat(s):

As some of the area lies in protected areas, then the main threats of habitat degradation have been lessened, although some risks lie in tourist developments close to major roads and forest/grassland fires.

Conservation Actions

This species was not listed as threatened in 1983 (Wells et al. 1984). It was reviewed in 1990 and again not thought to be threatened (Wells and Chatfield 1992).
