Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Mollusca Gastropoda Stylommatophora Hygromiidae

Scientific Name: Actinella giramica (R.T. Lowe, 1852)
Taxonomic Notes: Mandahl-Barth (1950) and Bank et al. (2002) treat this as a separate species. Waldén (1983) noted the status as a distinct species from nitidiuscula was uncertain. Seddon (pers. com, 2010) noted that detailed surveying may allow the recognition of the species limits between A. nitidiuscula and A. giramica.

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 2.3
Year Published: 2011
Date Assessed: 2010-09-24
Assessor(s): Seddon, M.B. & Abreu, C.
Reviewer(s): Groh, K., Cuttelod, A. & Neubert, E.
Justification:
This species is known from a valley inland from Cabo Girao and is threatened by habitat loss due to the development of tourist accommodation. Seddon (2008) proposed the listing should be as Vulnerable (VU) D2, based on restricted area and possible threats of habitat decline due to development of land. This listing was confirmed during evaluation of this assessment (November, 2010).

Threats [top]

Major Threat(s): The habitat has been subject to changing land-use practice as a result of hotel developments and increasing urbanisation and as such the quality of the habitat has declined (Seddon 2008).

Conservation Actions [top]

Conservation Actions: The habitat does not lie within a protected area and has been subject to changing land-use practice for the last 50 years as result of hotel developments and increasing urbanisation  (Seddon 2008). Habitat monitoring and population monitoring are required to establish the species limits and check the long-term trends for the species.
