Habitat and conservation
Poyntonophrynus hoeschi inhabits very dry semi-desert areas near rock outcrops. Breeding takes places in temporary rock pools where males call after heavy rains.[1][3] It a reasonably common species in suitable habitats. There are no significant threats to it, apart from possible effects of overgrazing. It is present in the Namibia Desert National Park and—probably—in some other protected areas too.[1]
