Abstract

During field surveys in the Spring of 2018 we made two observations of Leopard Tortoises (Stigmochelys pardalis) on roadsides near Lambert's Bay, WC, South Africa. One was a deceased adult female, killed as a result of a tortoise-vehicle collision. The other was a live adult females, which was move off the road in the direction she was headed. These observations illustrate that even the largest tortoise species in the region can be suseptable to road mortlaity, a known threat of turtle and torioses populations globally. Furthermore, these observations occured well outside the species presumed native range and listed introduced range. 

Highlights

  • Biodiversity Observations is an open access electronic journal published by the Animal Demography Unit at the University of Cape Town, available at https://journals.uct.ac.za/index.php/BO/

  • A study assessing driver attitudes on animal-vehicle collisions in Northern Tanzania, found that drivers said they were least likely to hit leopard tortoises due to the perceived damage it could cause to their vehicles (Kioko et al 2015), as they are one of the largest species of tortoise on the continent (Boycott and Bourquin 2000)

  • The direct effect of road mortality has a high likelihood of effecting many African reptile populations, especially for long-lived species with low recruitment rates that are negatively impacted over the long-term by small increases in adult mortality
