Drawing to a close

So my time here is drawing to a close. I haven't written in this blog as often as I should have but pressure of work is my excuse. I have now completed two spoor surveys and two and three quarter camera surveys. I am moving into the social part of my research for my last two months here and will be administering questionnaires and doing interviews with as many farmers as I can.

Below are a few pictures that show what I have been up to for the past several months:

Rare sighting

Its been far too long since I have posted on this blog and for that I apologise. My only excuse is that I have been incredibly busy.

One camera survey has now been completed and there are only 10 days left on the second. The second spoor survey is also underway and should be finished by the end of July or thereabouts. Although if the unseasonal weather continues (as I write it is raining - in June!!) it might take a little longer.

Anyway - what prompted me to finally post to this blog again was this photograph I got the week before last on one of the farms I am now camera trapping on.




For those of you who don't know it is a Black-footed cat (Felis nigripes) and is quite rare. It is the only picture of one that I have got in over five months of camera trapping in this area so it is quite a find.

The camera surveys have turned up a total of four leopards - one male, two females and a sub-adult. Quite a few cheetah, several caracal and African wild cat, a lot of brown hyaena and a huge number of black-backed jackal.

Away from work - I went on a trip to the Central Kalahari Game Reserve with some friends last month and we had an amazing 23 lion sightings. Not all in one group either but several different prides and also a mating pair. Here are a couple of photos.

Not so nocturnal after all!

My camera trapping survey is now into its fourth week and the variety of species captured so far is quite impressive. Sixteen different species of mammal have been photographed, including nine different carnivore species. This might seem what you would expect in an African bush environment, but this is on a cattle farm and so competition for resources is high.
One of the more suprising photographs has been of my target species, the caracal, in broad daylight. Daytime sightings of caracal are occasionally reported in protected areas, but in areas of high human activity they are rare.

Other interesting captures have been of an African wild cat (Felis lybica) and a striped pole cat (Ictonyx striatus). I have also got plenty of images of that nocturnal enemy of car suspension, the aardvark (Orycteropus afer).




The cameras have so far stood up well to the torrential rain we have been having for the past few weeks, the spoor survey however is now badly behind schedule. Tracking cannot be done when there is rain during the evening and night as the spoor is obliterated from the sandy substrate. On many occasions in the past few weeks I have got up at 4.45 in the morning to pick up my tracker and driven the 20 or 30 kms to the farm on which my transect for that day is located, only to find that it has rained and we cannot work. Getting up that early is irksome even when it results in the collection of data, when it is for nothing it becomes a dreaded chore.

The farmers need the rain though and the landscape is now looking very green and lush. It is remarkable how quickly this arid environment can transform from dry, sandy scrub to rich grazing land.

First pictures

I have now completed my pilot camera trapping period and have started the survey proper. Here are a couple of nice pictures I got in the first ten days during the pilot.

Spy in the camp

I am now starting, what for me, is potentially the most exciting part of my research - camera trapping. Studying predators can be incredibly frustrating as they tend to occur at low densities, are secretive and generally either nocturnal or crepuscular. All of these things make them very difficult to see! However, the advances in digital camera technology have made the use of remote cameras increasingly useful as a tool to gain information on population density and abundance. It also provides a window into the world of the predator that only a few years ago would not have been available. By setting motion sensitive cameras on a farm in my study area I can get a picture of the variety of different species that are using that land and in what numbers they exist, how many have young with them and what their movement patterns are.
For caracal in Botswana this is very exciting as there has been no research done on this species here. However, having the cameras out on the farm means that, although I am primarily interested in caracal, I can gather data on all the other predator species too.

Am looking forward to seeing what turns up!
