Scientific Name: Afrixalus stuhlmanni
Species Authority: (Pfeffer, 1893)
Taxonomic Source(s): Frost, D.R. 2015. Amphibian Species of the World: an Online Reference. Version 6.0. New York, USA. Available at: http://research.amnh.org/herpetology/amphibia/index.html.
Taxonomic Notes: There have been considerable doubts as to the validity of this species and it was considered to be a nomen dubium by Pickersgill (1996). However, we follow Pickersgill (2000, 2005) in considering it to be a valid form. Pickersgill (2005) considers Afrixalus sylvaticus to be a subspecies of A. stuhlmanni, but for the time being we retain them here as separate, though closely related, species that hybridise in areas where forest has been cleared.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): Martin Pickersgill, Arne Schiøtz, Kim Howell
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species is traditionally known only from Zanzibar Island in Tanzania. However, recent studies have shown that it occurs on the Tanzanian mainland from Amboni in the northeast, south to Liwale in the southeast, and inland to the Kilombero floodplain, as well as on Zanzibar. It is generally found below 300m asl.

Population [top]

Population:It is an abundant species in suitable locations.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of grassy pools and marshes in humid shrubland, mixed farmland and savannah. It breeds in marshes, shrub-dominated wetlands, and permanent pools.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Overall it is not threatened, and it is an adaptable species, but certain populations are affected by urbanization and water pollution. It is hybridising widely with the forest species, Afrixalus stuhlmanni sylvaticus, in areas where forests have been destroyed or heavily disturbed.

Conservation Actions [top]

Conservation Actions: It probably occurs in several protected areas.
