Justification
The species was originally assessed as Vulnerable in the earlier Red Lists (1994), as it had a small area of occupancy, and it was considered as Vulnerable (B and D)in subsequent revisions of the Red List categories and criteria (2000). The speciesDisculella spirulinawas considered by Seddon (2008) to beVulnerable B2ab(iii) (version 3.1) as it has an area of occupancy of under 60 km2, and is known from 5-10 locations along the coast. It is considered more rare than the other species of Disculella, as it is found in lower abundance at sites.Although there is still plenty of habitat suitable, the restricted distribution and habitat disturbance grant this species the status of Vulnerable (VU) D2. If part of the region was protected, thenthe reduced risk of disturbance would probably allow the species to be considered as Near Threatened (NT).

Management

Conservation Actions

Conservation Actions
Habitat monitoring is required at selected sites to ensure disturbance is not impacting the species. There are few protected areas in the range of this species, and establishment of a small area would benefit the species through reduction of the impact of development for tourism.
