While the loss of biodiversity in response to anthropogenic drivers is well documented, reptiles are underrepresented in global biodiversity and conservation assessments. Although more than 20% of all reptile species are currently listed as threatened, and a growing body of evidence highlights the sensitivity of reptiles to habitat change, basic information on the distribution, natural history, and conservation status of African reptiles remains sparse. Habitat loss via agricultural land-use change is regarded as the primary threat to global biodiversity and to southern African reptiles in particular. Inland, arid southern Africa has been identified as an area of global conservation priority for reptiles. However, the status of Zimbabwe’s reptiles and amphibians remains largely unknown. Limited resources and more urgent concerns have hampered what Zimbabwe has been able to achieve with respect to international conservation initiatives. Furthermore, the ecological impacts of recent, wide-scale land-use change in the country have received little attention. As legacies of historical land-use change are acknowledged as determinants of current landscape ecology, addressing the long-term effects of land-use change on Zimbabwe’s reptiles is crucial for effective conservation and management. Here, we provide a complete account of the reptile species recorded in south-eastern Zimbabwe and demonstrate the use of occurrence data from multiple sources to produce a species richness model for the region as a baseline to inform future conservation assessments. We discuss the model prediction in the context of current land-use patterns. Our study increases the number of published reptile occurrence records from the region by an estimated 285%.
