October 2 - 23 November (More New Species!)


Sunset over Medike.
This two-month period was very busy and more productive than we could have hoped for. Our species lists grew very nicely with many new reptiles, two frogs, a new mammal and some new birds. The SCBC was fortunate enough to have two volunteers participate on the programme. Laura Burton from Norfolk in the UK gave eight weeks to the SCBC. Laura who is pursuing a career in wildlife policy and legislation is interested in herpetology, specifically testudinoidea. Then we had Ruan Stander from Polokwane, South Africa who gave just under two weeks of his time. Ruan is an avid herpetologist with a bright future ahead of him. Thanks to both of you for your hard work and company in the field without you this period would not have been as productive.

October and November of this year was characterised by extremely dry and hot weather, the prevailing el Niño kept the rains away. We experienced numerous heat waves, some days the temperature rose to the mid-forties. Due to the heat we worked a lot at night, doing night hikes on a near daily bases. This led to a spike in our reptile species list with a majority of new species being nocturnal. Continuing our ‘broadening horizons’ programme we also did weekly road-cruising drives around the western Soutpansberg and a few forays into Eastern Soutpansberg and Northern Limpopo (Namely Golwe-Vhurivhuri, Pafuri and Mapungubwe). These new activities have led to some exciting sightings and interesting species.


For the two-month period we found six new reptile species on the Medike property alone and the total of new species for our list during this period for the greater Soutpansberg area was eleven (an additional two species can be added for the greater Limpopo area). Amphibians one new species for Medike and a total of two new species for the area. Scorpions one new species for the area. Birds we found four new species on Medike (we are not doing a greater Soutpansberg list as birds are very well documented in the area. We also have a new mammal record, an aardvark caught on camera trap by Medike resident Alan Carr. 

Black File Snake, Gonionotophis nyassae. A beautiful and strange snake. A new species for our lists.
A rare encounter: leopard, Panthera pardus, on foot. A definite highlight for me.
Highlights for the period was seeing a Black File snake for the first time. These snakes are strange, the exude a sweet smell which is very strong and part of this docile animals defence. The body is triangular with beautiful rough scales jutting out from the skin giving the snake a beaded feel. This has been one of the most magical reptilian encounters I have experienced. The second highlight for me was seeing a leopard on foot for the first time. We just set out on our night walk and saw some eye-shine, immediately one could see that this was not the usual night animal we regularly encounter. The animal continued to move in our direction and soon we could se the profile and spots. It was the big tom we have been capturing on our trap over the past few months. The leopard continued to move in our direction and at some point the animal sat down about thirty metres away and watched us. We stood and watched the leopard while he sat and watched us for about fifteen minutes. Then we moved away and backed out of the sighting. Leaving the cat there undisturbed. This was definitely one of the most magical encounters with an animal I have ever had. A rare meeting that I will never forget.

SCBC and Scorpions


Uroplectes chubbi, Medike.
In the last few months the SCBC has started to do more serious work on scorpions in the region. With encouragement and support from Ian Engelbrecht and the ‘Scorpalerts group’ we have been logging our scorpion by-catch and doing some UV lighting in the all the areas we have been working. On our September trip we got thirteen species in total with some significant records of Uroplectes chubbi and Pseudolychas pegleri. The region we found to be richest in scorpion diversity was Nwanedi, the area with the most individual scorpions was Golwe-Vhurivhuri (Pseudolychas pegleri) and Pafuri River Camp (high concentrations of Hottentota trilineata and Lychas burdoi).

At the moment our scorpion list for the Soutpansberg and peripheral areas stands at 16 species. To put it into perspective Mozambique is known to have eighteen species (Leeming, 2003; 84).Thirteen of these are on the Soutpansberg proper. In this list we have one endemic species (Opistophthalmus lawrencii). Scorpion diversity is high in the region and the list can be expected grow during 2016 as we increase our activities in different areas.

Scorpions can be found through active searching under cover (dead bark on trees, stones etc.), the easiest way by far of finding scorpions is by UV lighting. The only equipment needed is a UV torch (commercially available), eye protection for longer UV sessions (yellow goggles) and collection jars  for controlling the animals (I use pill vials for smaller species and glass jars for larger species). For those interested a good place to submit records is the ADU scorpion map page (click here to view page).

Below is an illustrated list of scorpions from our records for the Soutpansberg and peripheral areas in the Limpopo Basin. As we increase our activities in the region we expect to see our lists grow. Watch this space!
