Although this species has a restricted range with an area of occupancy of 84 km2, it is present all around the coast of Madeira and is known at more than twenty sites. Furthermore, there are plenty of inaccessible habitats between the sampling points and the species is expected to be present on these cliffs and slopes. It is noted that there has been some decline in habitat quality in the areas of tourist development in the last 15 years and it is suggested that research is carried out to see if this species can colonise artificial habitats (walls, gardens, bridges). This species is listed as Least Concern (LC).
This species is endemic to the Madeiran islands, where it is restricted to Madeira where it is found in coastal habitats all around the island.
The population is considered to be stable.
This species is found on ledges and rock faces on coastal crags, walls and other rocky habitats all around the island. Wollaston (1878) noted the affinity to Sempervivum tabulaeformis, finding specimens around the dried leaves and roots.
Like Leiostyla fusca, this species is found in dry habitats, on ledges and rock faces on coastal crags, walls and other rocky habitats all around the island and so it is only under localised threats of habitat disturbance due to tourism developments (gardens, walls, bridges).
No known conservation actions are in place for this species, however research work should be undertake to establish whether the species can colonise the artificial habitats provided by plantations and tourism developments (gardens, walls, bridges), as the coastal areas are the more developed habitats on Madeira.
