Distribution and habitat

The Highveld gerbil is endemic to southern Africa. Its range includes Angola, Botswana, Lesotho, Mozambique, Namibia, South Africa, Eswatini, Zambia and Zimbabwe. Its typical habitat is grassy plains with scrub or open woodland on sandy soils,and it also occurs around marshes and pans on peaty soils.

Ecology

The Highveld gerbil is sociable, with several individuals living in close proximity to each other. It digs a complex burrow in loose, sandy soil which may extend for. There are several entrances and a single nesting chamber. The animal is nocturnal, and chiefly active around dusk and dawn. Its diet consists of plant material, including the green parts and roots, and a small proportion of insects. Females may have five or six litters per year. The gestation period is about three weeks and the litter size averages three young.
