Assessment Rationale:

This species is endemic to La Gomera where it is found in a single location which lies close to the capital of the island, and hence there is a risk that urban encroachment will lead to decline of the habitat, and hence impact this species. It is therefore listed as Critically Endangered (CR) B2ab(iii).

Geographic Range:

This species is endemic to La Gomera where it is found in a single site on the south-eastern coast between 200 and 600 m asl (Valido et al. 2000 gives a map).

Population:

There is no data on the population, but it is believed to be rare (Groh, pers. comm., 2010).

Habitat and Ecology

This species occurs in pine forest and in "piso basal", typical lowland vegetation.

Major Threat(s):

There are no specific  threats listed in Moliner Gomez et al. (2001), however the site lies close to the capital of this island, and hence the site is potentially vulnerable to encroachment of urban areas.

Conservation Actions

This species is  listed as Near to Extinction by Moliner Gomez et al.(2001) and Endangered by Valido et al. (1999). Proposed conservation actions include protection of the habitat and long-term monitoring.
