Assessment Rationale:

Seddon (2008) assessed this species as Least Concern (version 3.1) noting that species meets the range criteria for Vulnerable B1, but the presence in suitable habitats in at least 10 different valleys on the island in habitats that are protected, suggests that a lower category is merited for the species.  Hence given the presence in these valleys throughout northern Madeira and the low level of threats, the species is given a confirmed assessment as Least Concern (LC). 

Geographic Range:

This species is endemic to Madeira. It is only known living on the northern side of the island where it occurs from coast to intermediate elevations. Wollaston (1878) noted that this was the rarest of the Craspedopoma species on Madeira. However recent surveys show that it is present in many more sites and that two other species C. monziana and C. lyonnetianum are both rarer species.

Population:

This species is present in suitable habitats in more than 10 different valleys on the island in areas that are protected,which suggests that it is reasonably widespread.

Habitat and Ecology

This species is found in damp shaded wooded areas amongst leaf litter and mosses, and on the underside of stones.

Major Threat(s):

The inland sites are fairly intact, with only the coastal habitats show signs of habitat degradation. This is due to urbanisation, clearance and disturbance along the roadsides.

Conservation Actions

The species is found in protected areas, suggesting there are some measures in place for its conservation.
