The end of April 2011 marked the conclusion of the four month Boland southern survey, which was conducted in the Jonkershoek and Hottentots-Holland Nature Reserves, the Kogelberg Biospere Reserve, as well as privately owned mountain land adjacent to this core area.

The southern study area is more fragmented by towns and farmland than the Limietberg NR, which represents a more continuous wilderness area.We were quite curious to see how this would affect leopard numbers and ranges.
The animals did not disappoint! Analysis of photographic data from 82 cameras at 50 locations revealed the same species assemblage as r the Limietberg survey. The 22 mammal species recorded in the southern area included African wildcat, grey rhebuck and large grey mongoose. Some gems among the last batch of pictures collected were two beautifully clear, full body photos of Cape clawless otter (Aonyx capensis) and water mongoose (Atilax paludinosus).

The diamond among the gems was a series of pictures showing a female African striped weasel (Poecilogale albinucha) carrying her young in her mouth past our cameras. These pictures were particularly encouraging since they were taken just a couple of weeks after the devastating fire that raged through the Kogelberg Nature Reserve in March 2011.

On the leopard front we were also very satisfied – 18 adult leopards and 2 cubs were identified in the study area. The leopard numbers from both surveys suggest that leopard density in the Boland appear to be higher than in the Cederberg, but further analyses will be conducted to confirm this.

Surprisingly, the territory of one of the dominant males, Scott (BM12), even spans the N2! This means that he would need to cross the highway to patrol his territory illustrating how adaptable these enigmatic cats are. His territory stretches from the southern peaks of the Hottentots-Holland Mountains, southwards through the Steenbras Nature Reserve and eastwards into the Kogelberg Nature Reserve. Motorists please beware of leopards crossing the road on the N1 & N2 in mountainous regions, particularly early in the morning or at night!

Popeye (BM17) looks to be another ‘main man’ in the Southern study area and was captured at nine different sites. He roams all the way from the high peaks of the Hottentots-Holland that majestically fringes Somerset-West, south-eastwards through the Groenlandberg, with our most southerly capture in the Houwhoek region.

All our cameras are currently re-deployed in the Limietberg, and we are very excited to collect the first results next month – so watch this space for another interesting update!
