Every decade or so we experience a drought here at Djuma Game Reserve. This is due to the weather oscillation known as El Nino and El Nina which on average seem to change global weather patterns every ten years or so. In the December 2002 issue of Drumbeat I describe the El Niño / La Niña effect and its consequences for Djuma Game Reserve, click here to read that article. In that article I suggest that - given historical records - we would have a drought; it was an easy prediction to make - unfortunately! For the 2002 / 03 wet season we recorded 207 mm (annual rainfall is usually almost 600 mm) and for this season so far we have recorded about 100 mm (with another two or three months of the season still to go). We have been lucky in that the years before 2002 were above average in annual precipitation (several flood years in fact). Furthermore, the rain that we have received so far in these two years was mostly soft rain as opposed to torrential downpours; this matters since a downpour washes away the barely covered soil and thus making it harder for the plants to cope with the stressful conditions. On the other hand, gentle rain helps the perennial grasses to have a green flush after the rain. These green flushes last a few weeks, but are eventually beaten down by the relentless grazing pressure of hungry animals as well as the brutal conditions that prevail at soil level, day after day of 40 degrees Celsius. When air temperature is that high, soil temperature is even higher; almost 70 degrees Celsius - too hot to walk on barefoot. This will be the first drought in more than a half-a-century that the reserve will be without a fence between it and other reserves, including the enormous Kruger Park. We used to have fences between ourselves and most of our neighbours - since the sixties there has been a fence between the Sabi Sand (of which Djuma is part) and the Kruger National Park. These fences were all removed in the early nineties and now there is only the outer western boundary of the greater Kruger Park that remains as a fence - and of course remains so since in SA we firmly believe in the separation of pristine animal habitats from human settled land. The removal of the fences was seen as an ecological imperative since they were seen as major contributors to the devastation caused by previous droughts. In the 1991 / 2 and the 1982 / 3 droughts it was heart-breaking finding most of the animal deaths occurring along the fence lines. Instinctively the animals seem to know that in such dire times they need to migrate to climes that may have received better rainfall - the fences prevented them from doing so. It will be interesting to see whether the removal of the fences will help more animals to survive the coming winter months, our dry season. The northern end of the Kruger Park received almost 200 mm last week and given that nothing - other than distance (about 300 km) - now prevents animals from moving to where there is green grass. It must be noted that droughts are a normal part of the life cycle in the savannah and all animals and plants - large and small - have evolved survival strategies. In fact, savannahs are defined by their erratic rainfall, years of plenty are followed by years of little. Ce la vie! The last time the dam in front of Vuyatela dried up was in 1998 - the year we started Africam and thus we have pictures from every day since October 1998. In 2000 we had floods, the pictures below show the changing dam from empty to over full to empty again over the intervening five years. We have now dismantled the ugly old cement crib featured in so many of the photographs - it cracked and we have now replaced it with a more natural looking pan. We now pump water to several pans on Djuma Game Reserve - Cheetah Plain pan, Three-in-a-Row pan, the pan at Bush Lodge, the pan in front of Vuyatela and the pan in front of Galago Camp. We do this to ensure that the animals have access to water, but of course we need to be judicious in our water use, not just for obvious reasons of water conservation, but also because such pans can have a negative impact on the surrounding landscape and plants since such "permanent" water holes in times of stress can lead to overgrazing and eventually erosion. Game sightings have been awesome and we have had an endless stream
of animals coming to artificial water holes at the lodges. Jurie Moolman |

These two images from November 1998 show the dam with
no water.

These two images from early 2000 show the dam overflowing
full. This was the flood year.

December has been very exciting and busy as the build up to the festivities
happened. An EcoTraining student group doing their practical module
took up the first two weeks of the month. The group spent a very nervy
night on a sleepover at Buffelshoek dam. Great game sightings were experienced
and many memories will be held for a long time to come. Until next month, |
