Assessment Rationale:

This species is relatively uncommon. It  has adapted to secondary forests and is present on almost all islands in the Azores. There are no major threats thus it is considered as Least Concern (LC).

Geographic Range:

This species is recorded from all the islands of the Azores, except Corvo.

Regions:
Portugal - Azores
Extent of Occurrence (EOO):
(km2)
Area of Occupancy (AOO):
(km2)
Elevation Lower Limit:
50 (m)
Elevation Upper Limit:
1040 (m)
Biogeographic Realms:
Palearctic
Presence:
Extant
Origin:
Endemic Azores
Seasonality:
Resident

Population:

Although found throughout the Azores, it is an uncommon species, found primarily in forests, endemic and secondary. Backhuys (1975) attributes its rarity to the destruction of the mountain, endemic habitat, which the species seems to prefer over the secondary forest

Habitat and Ecology

Acanthinula azorica lives in forested habitats, endemic and secondary, although preferentially on mountainous, endemic vegetation. It is found mainly under decaying leaves. On Pico island, for example, it was found from 150 m to over 1000 m ASL (Martins et al. 2006), and Backhuys (1975) collected it on Flores at about 50 m ASL

Major Threat(s):

This species is relatively uncommon; however, because it has adapted to secondary forests and is present on almost all islands, no threats are foreseen.

Conservation Actions

No conservation actions are needed.
