Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Simon Loader, Kim Howell, David Gower, John Measey, Mark Wilkinson
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern because, although it is seldom recorded, it has a relatively wide distribution, is probably not dependent on threatened habitats, has a presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It has been recorded from open areas and deciduous and strongly seasonal scrub and woodland. It was found in black mud in an open area near the Ruvu River at Bagamoyo, and is perhaps dependent on estuarine muddy areas, but it is clearly not a forest-dependent species. It is probably a viviparous species, not dependent on water for breeding. It has also been reported as abundant in agricultural habitats with suitable crops that provide shade and maintain the top soil.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Large-scale mechanical rice farming is a possible future threat.

Conservation Actions [top]

Conservation Actions: It is not known from any protected areas.
