Scientific Name:	Gulella salpinx
Species Authority:	Herbert, 2002

Assessment Information [top]

Red List Category & Criteria:	Critically Endangered B1ab(iii) ver 3.1

Justification: All known specimens of Gulella salpinx have been collected from an area of less than 1,000 m²; the total extent of the geological formation to which the species probably is restricted is approximately 40 km². It is believed to be endemic to a single site, a limestone outcrop. The KwaZulu-Natal south coast is a relatively well collected area, but this species has not been found at other localities in the region. It appears to be restricted to this geological formation, which has only recently been surveyed for molluscs. Two companies have extensive quarrying operations in the area and it is heavily invaded by alien plants.

Geographic Range [top]

Range Description:	Known from only one location: believed to be endemic to a single site, a limestone outcrop. The KZN south coast is a relatively well collected area, but this species has not been found at other localities in the region. It appears to be restricted to this geological formation, which has only recently been surveyed for molluscs (Herbert 2002). All known specimens have been collected from an area of less than 1,000 m² (estimate based on field survey, Herbert 2001); total extent of geological formation to which it is probably restricted ca. 40 km².

Conservation Actions [top]

Conservation Actions:	The two mining companies operating in the area have been notified of the existence of this species and have expressed their willingness to play a part in its conservation. They have offered to support a survey of additional habitat fragments within the marble deposit to try to identify further colonies.
