This species is found in North Eastern South Africa, Northwest Swaziland, Southern Namibia and eastern Zimbabwe (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Juvenile V. gariepensis in rocky habitats frequently show the bright colour patterns attributed to B. robinsoni (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
V. gariepensis is similar to B. robinsoni. B. robinsoni can be distigushied based on its orange back with green spots, poorly developed parotoid glands, weakly developed tarsal fold, small tympanum, relatively smooth skin, and relatively large eye (Branch and Braack 1995). V. gariepensis is found mainly along river banks while B. robinsoni is found in springs and temporary water sources (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Habitat and Ecology
Habitat and Ecology
V. gariepensis inhabits the thick and Grassland Biomes. This species can survive in areas of low temperature and extrememly arid conditions, and has even been found moving in the snow (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Life History and Behavior
Males may call during daylight hours in overcast or rainy weather, as well as at night (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Channing (1998) states that V. gariepensis is an opportunistic breeder and is found breeding in many different water souces, including seepages and spongy bogs, as well as hoof prints of cattle and even small pools found under leaking taps. Most breeding takes place during the winter however if enough water is present summer breeding has been recorded (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
The tadpoles form a squirming mass and grow to a maximum length of 24 mm after only a few days. According to Lambiris (1988e), metamorphosis is usually completed after 20 days (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

IUCN Red List Category and Justification of Conservation Status
Least concern: V. gariepensis has an extensive distribution range and is abundant, but some isolated populations may be speciating (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
