Port Nolloth, Northern Cape Province.
Port Nolloth was the main reason for our party coming to Northern Cape Province. The sand dunes and open scrub-desert to north and south of the small coastal town 89kms northwest of Springbok, are the habitat of the Namaqua dwarf adder (Bitis schneideri), one of the species being studied as part of Tony Phelps' threatened adder project.

Unloading the herpers at dawn.
We made several day trips from Springbok to Port Nolloth, arriving before dawn to enable us to herp before the sun got too high and the day became too hot. In the early morning it was extremely cold at Port Nolloth, a bitter wind coming in off the Benguela Current as it heads north from the South Atlantic.

The coastal habitat comprises sand dunes and flats with clumps of low salt-tolerant xerophytic vegetation. Our search method consisted of close-examination of the roots of these clumps for secretive reptiles. We did not find any Namaqua dwarf adders and discussions with locals led us to believe they were being illegally collected for reptile keepers. All reptiles we found were photographed and replaced.

The only gecko we found was Austen's thick-toed gecko (Pachydactylus austeni) but lacetids were more common, if difficult to approach.

Smith's desert lizard (Meroles ctenodactylus) was extremely alert and difficult to approach although it was possible to capture specimens of Knox's desert lizard (M.knoxii) and the Namaqua sand lizard (Pedioplanis namaquensis).

Although skinks with legs, Western variegated skink (Trachylepis punctulata) were present, legless dart skinks were more common, in the roots of the coastal vegetation where three or more could be found in a single clump, ie. the Little Namaqualand striped dart skink (Microacontias lineatus tristis) and two colour phases of the Coastal dark skink (M.litoralis)
