Animalia Chordata Amphibia Anura Bufonidae

Scientific Name: Capensibufo rosei
Species Authority: (Hewitt, 1926)
Common Name(s):
English Rose’s Mountain Toadlet
<i>Bufo rosei</i> Hewitt, 1926
Taxonomic Source(s): Frost, D.R. 2014. Amphibian Species of the World: an Online Reference. Version 6 (27 January 2014). New York, USA. Available at: (Accessed: 27 January 2014).
Taxonomic Notes: A recent phylogeny of this genus suggests that there may be more than two species, and that Capensibufo rosei on the Cape peninsula may be substantially different from subpopulations from other sites (Tolley et al. in press). Resolving the taxonomy of the genus is a conservation priority for this taxon.

Geographic Range [top]

Range Description:This species occurs only in south-western South Africa, where it is restricted to the mountains south-west of the Breede River, including the Cape Peninsula (an Extent of Occurrence of 6,526 km2 with and Area of Occupancy estimated to be 2% of its Extent of Occurrence). Its altitudinal range is 60 to 1,600 m asl, with more than 80% of localities being above 400 m asl.
Countries occurrence:
South Africa (Western Cape)
Additional data:
Estimated area of occupancy (AOO) - km2:130
Continuing decline in extent of occurrence (EOO):Unknown
Number of Locations:8
Lower elevation limit (metres):60

Population [top]

Population:It is locally common at breeding sites, and large breeding aggregations can sometimes be found. However, it is absent from some apparently suitable sites and can no longer be found at some historically recorded sites on the Cape peninsula.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Yes
Extreme fluctuations:UnknownPopulation severely fragmented:No
Continuing decline in subpopulations:Yes

Habitat and Ecology [top]

Habitat and Ecology:It is a species of mountain fynbos heathland, and does not survive in altered habitats. Adults congregate to breed in temporary pools, where they lay around 100 eggs in long strings of amber jelly.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Congregatory:Congregatory (and dispersive)

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The main threat to this species is the loss of its fynbos habitat, mainly because of the spread of alien vegetation and frequent burning. No explanation or threat has been deduced for historical populations now missing from the Cape Peninsula.

Conservation Actions [top]

Conservation Actions: Taxonomy, understanding ecology, threats and population size and trends are all high priority areas for research in conserving this species. Known sites need active management to reduce influence by alien vegetation. Much of the range of this species is within protected areas.
