eeding population, as well as its geographical isolation is also taken into consideration. Species categorized as medium normally do not occur at high population numbers, but cannot be deemed as rare. Low probability of occurrence will imply that the species’ distributional range is peripheral to the study site and habitat is sub-optimal. Furthermore, some reptiles and amphibians categorized as low are generally deemed to be rare. Based on the impressions gathered during the site visit, as well as publications, such as FitzSimons’ Snakes of Southern Africa (Broadley, 1990), Field Guide to Snakes and other Reptiles of Southern Africa (Branch, 1998), A Guide to the Reptiles of Southern Africa (Alexander and Marais, 2007), Amphibians of Central and Southern Africa (Channing, 2001), Atlas and Red Data Book of the Frogs of South Africa, Lesotho and Swaziland (Minter, et al, 2004) and A Complete Guide to the Frogs of Southern Africa (Du Preez & Carruthers, 2009), a list of species which may occur on the site was compiled. The latest taxonomic nomenclature was used. The vegetation type was defined according to the standard handbook by Mucina and Rutherford (eds) (2006). 6.4.3. Specific Requirements During the visit the site was surveyed and assessed for the potential occurrence of Red Data reptile and amphibian species in Mpumalanga (Alexander and Marais, 2007; Minter, et al, 2004, Du Preez & Carruthers, 2009, 2009; Measey (ed.) 2011 and Carruthers and Du Preez, 2011), such as: During the visit the site was surveyed and assessed for the potential occurrence of Red Data species such as: • Giant Bullfrogs (Pyxicephalus adspersus); • Desert Rain Frog (Breviceps macrops); • Namaqua Stream Frog (Strongylopus springbokensis); • Karoo Caco (Cocosternum karooicum); • Speckled padloper (Homopus signatus); • Namaqua Day Gecko (Phelsuma ocellata); • Namaqua Plated Lizard (Gerrhosaurus typicus); SATO Aggeneys July 2011 42
• Armadillo Girdled Lizard (Cordylus cataphractus); • Lawrence’s Girdled Lizard (Cordylus lawrenci); • Lomi’s Blind Legless Skink (Typhlosaurus lomiae); • Namaqua Dwarf Adder (Bitis schneideri); • Fisk’s House Snake (Lamprophis fiskii) • Southern African Python (Python natalensis).
