Assessment Rationale:

Craspedopoma mucronatum is widespread in suitable habitats at intermediate elevations on the south coast and coastal areas and intermediate elevations on the north coast, and although it has a restricted extent of occurrence, the lack of threat and stable populations at present suggest that the species does not meet the criteria for listing as a Species of Conservation Concern. It is considered as Least Concern (LC).

Geographic Range:

This species is found within the Madeiran islands; this species is the most widespread of the Craspedopoma species on the main island of Madeira. It is present throughout the central intermediate elevations, as well as along the northern coast (Seddon 2008). There are Pleistocene fossils from within the Paleosols at Fonte de Areia, Porto do Morena and Pta da Canaveira on Porto Santo (Groh and Hemmen 1984, Cameron et al. 2006) and on Bugio of the Desertas indicating it was more widespread during the Quaternary.

Population:

This species is widespread in suitable habitats. Populations are apparently stable (Seddon, pers. comm., 2010).

Habitat and Ecology

This species is found in damp shaded wooded areas amongst leaf-litter and mosses and on rocky ledges in damp ravines amongst loose friable soil (Seddon 2008).

Major Threat(s):

Although there are localised habitat disturbances, the widespread range of the species at intermediate elevations on Madeira, means that at present these threats are not impacting the species.

Conservation Actions

At present the species is not declining and as such, no conservation actions are necessary, other than general protection of the habitats which should be provided by the two Special Protected Area's designated on Madeira: Laurisilva of Madeira and Maciço Montanhoso Central da ilha da Madeira.
