Chapter 3

Time runs backward

Magical as the southern Kruger National Park seemed to me when I first visited it as a small boy in 1954, it was a biologically impoverished area. Of the four biggest animals which had lived there up until the late nineteenth century, (elephant, hippo, white rhino and black rhino) only hippos survived. There were still elephants in the Park’s remote northern end, but black rhinoceroses and their giant relatives, white rhinoceroses, had disappeared from the entire area.

I pleaded with my parents, of course, during that 1954 visit, to drive up to Kruger’s northern end so that we could have a chance of seeing the elephants. Like the vast majority of visitors to the Park during the nineteen-fifties they preferred, however, to stay in the south. Looking back I suppose it could have been a matter of time and convenience for them – we would have had to drive more than a hundred miles to reach the Park’s northern regions, and that would have taken more time than they’d planned to spend away from Johannesburg. There was more to it than that though – a trip to the northern part of the Kruger Park was regarded, at that time, as a kind of expedition rather than a family vacation.

The feeling I got as a child was that Kruger’s northern end wasn’t only remote but even dangerous. It was closed to the public for much of the year because of the risk of malaria, and the elephants themselves were thought of as a hazard. My well-worn copy of Our South African National Parks, published in 1940, told me that you might see bull elephants alone or in small groups next to the road if you went up north, but

[t]he large herds, containing females and young, are shy and keep away from the roads; which is fortunate; since the former might react dangerously did they suspect any threat of harm to their children.

By the nineteen-fifties breeding herds were being spotted from the roads, but they were still thought of as dangerous. “Do not stop to photograph a herd of elephants with cows and calves,” Eric Robbins warned visitors to Kruger in his 1961 Africa’s Wildlife “but make haste to get away.” I remember promising myself after that first trip to Kruger that, when I was a grownup with my own car, I would travel to those mysterious and inaccessible northern regions. Perhaps I might even get a look (off in the distance, as my imagination saw it, through gaps between the green trunks of the fever trees) at the cow elephants and their young.

I remember, too, assuming that there had never been elephants in the southern part of the Kruger Park – that it just “wasn’t elephant country.” That was quite wrong. Elephants had been abundant there until ivory hunters equipped with firearms started operating in the area in the 1840s. The last elephants were seen there sometime in the early 1880s. By 1900 there were – apart from odd individuals wandering in from what was still “Moçambique”– very few elephants anywhere in the territory that would later become the Kruger Park.

In the early years of the twentieth century, conservationists managed to put an effective stop to hunting in that territory. As far as the elephants and rhinos were concerned, they were closing the stable door after the horse was gone. Elephants started filtering back, however, into the protected area from neighboring Mozambique as a result of the hunting ban. By the time South Africa’s northeastern frontier area was legislatively proclaimed as the Kruger National Park in 1927, the northern end of that area contained about 100 of them. At the time of my first visit to Kruger in 1954, that 100 had grown to about 700, and a small number of elephants had, in fact, already re-entered the southern end of the Park. Few people had, however, heard about these returnees, let alone seen them.

* * *

Fast-forward to 1991. I’m in the Kruger Park again – this time with my ex-spouse and close friend Delphine, and our teenage son Nick. Branches are cracking like rifle shots as a herd of elephants feeds about fifty yards from the road. I’m watching a young female through my binoculars. She’s prying a piece of bark off a 15-foot Acacia nigrescens tree with one of her tusks. Clamping it between her enormous, six-pound molars, she backs up and pulls. The tree bends to near-breaking before its foliage lashes violently upright as a sheet of bark rips free.

The 700 elephants that lived in Kruger at the time of my first visit nearly forty years before, have now become 9,000, and the animals have long since completed their re-occupation the southern part of the Park. The southern end is, in fact, where I’m watching the young female stripping the nigrescens.

Delphine – our best animal spotter – says that there’s a baby with the herd we’re watching. I haven’t seen it yet, but that’s not surprising – the elephants are feeding in thick bush. Delphine has noticed, too, that the herd is moving along a path that will intersect with the road a few hundred yards behind us. She suggests that Nick turn around, drive back a quarter-mile or so, do another U-turn, and wait for them.

While we’re doing this, I’m struck again by how different the bushveld looks now that elephants have returned to the area. The southern Kruger Park was a neat, literally park-like place when I first saw it as a child, but now there are dead trees all around us, and many of the living ones are coppiced or growing at odd angles. Even trees that have been pushed into a prone position can survive, I’ve noticed, if some of their roots have kept a hold on the ground – the horizontal trunks send up vertical branches that eventually look like a row of new trees.

Delphine has guessed right about where the elephants are planning to cross the road – they emerge from the bush right ahead of us. We’re excited to see that they’ve got not one, but two babies with them. A station wagon drives up and stops on the opposite side of where the animals are preparing to cross. The matriarch signals the other elephants to wait, and walks onto the road alone. Turning toward the station wagon, she spreads her ears and raises her trunk. The station wagon gives a little jerk as its driver shifts from park into reverse, but it only backs up a yard or two. That, I’m interested to see, is enough for the elephant – she seems more concerned with acknowledgment than with space. She swings her enormous body around and walks over to our car. Now it’s Nick’s turn to shift into reverse. Towering over us, the big cow extends her ears stiffly. We’re all a bit nervous, and Nick pushes the gas pedal too hard. The wheels spin on the dirt road, showering pebbles at the elephant’s front feet. For a second or two she looks down at us impassively through her long, crinkly eyelashes, then she turns away and signals the rest of the herd to follow her across the road.

The matriarch is perhaps the biggest of the ten or so elephants whose soft, ponderous steps are taking them between our car and the station wagon. Up close we see that the larger of the two babies is six months to a year old. The smaller one can’t have been around for more than a few weeks. Its legs twinkle back and forth as it runs between the great, slow-moving limbs which surround it.

In a world in which more species are disappearing with each passing year, time runs backwards in the Kruger National Park – not only elephants but Africa’s two rhinoceros species have come back from near-extinction to form viable populations there.

The white rhinoceros is a giant which weighs, on average, just on twice as much as the black rhinoceros. Perhaps because many people’s ideas about African wildlife are shaped by the fauna of the East Africa, the white rhino – which isn’t found in Tanzania or Kenya – remains a relatively poorly-known animal. The drama of its restoration from near-extinction to a state of relative abundance took place, moreover, in South Africa, which was, until the early 1990s, cut off from the rest of the world by the policies of its former government.

Fifteen thousand years ago white rhinoceroses did live in East Africa. Like the savannas themselves, with their characteristic acacia, combretum and commiphora scrub, the white rhino’s range stretched unbroken between Southern Africa’s Kalahari desert and Northern Africa’s Sahara. Then, starting around fourteen thousand years ago, Africa was abruptly subjected to a regime of enormously increased rainfall. This wet phase was the result of a world-wide climate shift which we’ll look at in more detail in the appendix to this book. The forests of the Congo Basin advanced into East Africa in response to it, cutting the grassy savannas of northern Africa off from those of southern part of the continent and dividing the grass-eating white rhino’s population, in the process, into a northern and a southern group.

The pluvial or rainy regime gave way to a drier climate four thousand years ago, allowing grassland to re-occupy what were once again becoming the Serengeti plains, but the northern and southern white rhino populations have not yet re-entered East Africa to rejoin each other. Along with a great many other dry-savanna species, ranging from the pygmy falcon Polihierax through the bat-eared fox to Kirk’s dik-dik, white rhinoceroses are still divided into widely-separated northern and southern pockets. Before human hunting reduced it to virtual extinction, the northern pocket of white rhinos was situated in an area where Chad, the Sudan, the Central African Republic, and the northern ends of Uganda and the Congo come together. The southern pocket lay some two thousand kilometers away, in southern Africa south of the Zambezi river.

The southern pocket of white rhinos was the first to face the destructive power of firearms. Dutch colonists had established themselves at the southern tip of Africa as long ago as 1652, and, as they moved into the interior of Southern Africa during the eighteenth and nineteenth centuries, the white rhino was among the first animals to disappear from the areas they settled. Despite the fact that malaria and sleeping-sickness delayed the intrusion of European settlers into the wilderness protected by the present-day Kruger Park, the area was, as I’ve mentioned, heavily hunted toward the end of the nineteenth century. The last white rhinoceros was seen there in 1894. By 1895 it was generally assumed that the entire southern population of white rhinos had ceased to exist. Because the existence of the northern pocket was not yet “known” at the time – i.e. known to non-Africans – it looked as if humans had just exterminated the planet’s third-biggest land animal.

It was then discovered – “to everyone’s surprise,” Ian Player tells us, – that a handful of these giant rhinos had survived about 100 miles south of the present-day Kruger Park at the confluence of the Black- and White Umfolozi rivers in Zululand. A certain C. R. Varndell responded to this discovery by organizing a hunting expedition into the area. Varndell and his friends shot six white rhinos. Judging from what he wrote about it in his Nature and Sport in South Africa, published in 1897, H. A. Bryden seemed to think that this was a good idea:

There can, I fear, be little doubt that this rare and interesting quadruped will within the next two or three years have become quite exterminated – a creature of the past. Naturalists will have to thank . . . Mr. Coryndon and Mr. Varndell for their skill and success in procuring the first – and probably the last – complete specimens of this mammal before its final extermination.

Others reacted in a more rational way to this attack on the last population of giant rhinos. A conservationist by the name of C. D. Guise wrote to the Governor of Natal, Sir Walter Hely-Hutchinson, demanding that the animals be given protected status as “royal game.” When Sir Charles Saunders, resident commissioner of Zululand, issued a proclamation to that effect in April of 1897, there were probably somewhere between forty and eighty white rhinos left in the Umfolozi area. Even if an isolated animal or two still survived in the remote areas of what are now Botswana or Zimbabwe at that point, it was quite clear that the Umfolozi survivors constituted the southern white rhinos’ last viable population.

That population responded so well to protection that, by the start of the 1960s, there were almost a thousand white rhinos in Zululand. The small reserves which had been created for their protection were, however, filling up at this time, and it seemed that the remarkable resurgence of their population might start to level off. Not far away from them, however, the Kruger National Park – bigger than Tanzania’s Serengeti National Park and Kenya’s Masai Mara put together – still lay empty of rhinos. Beginning in 1961, therefore, something which conservationists had been urging since the 1920s was finally undertaken: white rhinos were captured in Zululand and released into Kruger. The Kruger population has grown with gratifying speed, and there are, as a result, now well over two thousand of them there (and, as I mentioned in Chapter 1, over 12,000 overall).

* * *

The smaller, more secretive black rhino managed to hang on in the Kruger area longer than its giant white cousin. By the time hunting was prohibited there at the end of the nineteenth century, its population had, however, fallen to a critical low. Isolated individuals survived in the Kruger Park into the nineteen-forties, but the species had, years before, declined to the point of no return. Beginning in 1971, therefore, black rhinos (which had survived in viable numbers in the Umfolozi area in the shadow of the protection given to their giant white cousins) were translocated to Kruger from Zululand. Other black rhinos were brought in from Zimbabwe. Kruger is, as a result, now home to a small but fast-growing population of just over 300 animals.

Returning the black rhinoceros to Kruger was originally seen as a matter of restoring the area’s original fauna rather than a way of saving the species itself – there were, after all, still at least fifty thousand black rhinos in east and central Africa when that species was brought back to Kruger in 1971. During the next twenty years, however, the black rhino was eliminated from the east and central African savannas as rapidly and completely as the bison were wiped off the North American prairies a century earlier. Uganda, Kenya, Tanzania and Zambia lost well over 95% of their black rhinos during the 1970s and 80s. Even a famous sanctuary like the Serengeti National Park – still thought of by many people as an inviolable African wilderness – lost virtually all its rhinos. The few hundred black rhinos in Kruger (where poaching has, so far, been kept to an insignificant level) has become one of the few viable populations of this species in Africa.

The rhino-killing spree of the 1970s and 80s also pushed the northern pocket of white rhinos to the edge of extermination. The entire population of that pocket had by the year 2006 been reduced to some twenty individuals in Congo’s Garamba National Park, and another handful of animals – aging now, and not breeding – in zoos in the United States and the Czech Republic.

The unthinkable has happened: South Africa, where rhinos once hung on by the slenderest of threads, has become the last bastion of both the white and the black species.

* * *

In addition to being re-introduced to the Kruger Park, rhinos have been brought back to some of the other South African localities they used to inhabit in the eighteenth and nineteenth centuries. In 1992, for instance, a group of black rhinos was translocated from the Kwazulu Natal province on the eastern side of the country to the Lapalala game reserve in Waterberg mountains in South Africa’s “midwest.” Stressed by the move, a pregnant cow gave birth and abandoned her calf. Fortunately for the calf, it was found by humans rather than by one of the brown hyenas or leopards that inhabit the area. Weighing only 46 pounds, the little animal managed to survive on fat-free cow’s milk to grow up in the world of human beings. When I went to meet him recently, Bwana, now a seven-year-old adult, came running up to the log barrier which separates him from his human visitors to have his nose rubbed. His back felt as rough and cool as the bark of a tree, but the skin around his mouth and ears was soft and warm. I rubbed carefully over one of his eyes, expecting him to pull away, but he shut the eye instead, and leaned into my hand.

Bwana’s neighbor in the next boma was an adolescent female white rhinoceros. She’ll be much bigger than Bwana when she’s fully grown, but for now she’s the same size. The placid nature of white rhinos is often contrasted with the dangerously irascible disposition of their smaller black cousins, but Bwana is so attached to human company that it’s hard to see him as a dangerous animal. As he strained across the log barrier to get closer to me, we tried to touch noses. His front horn fetched up against the peak of my baseball cap. I turned the cap backwards, and found myself nuzzling a soft, dry stretch of skin between two huge, runny nostrils.

It’s widely repeated, these days, that the name “white rhino” is a “corruption” or “mistranslation” of the Dutch name “wijde renoster.” The word “wijde” (“wide”) is thought to refer to the white rhino’s top lip – the grass-eating white rhino has a straight, lawn-mower-type top lip, while the tree and shrub-eating black rhino’s top lip is pointed into a kind of mini-trunk. I don’t think this can be right. Firstly, the South African Dutch or Afrikaans name for the white rhinoceros isn’t (and has never been as far as I can tell) “wijde renoster.” It is, in fact, “wit renoster” (which means, simply, “white rhinoceros”). And nobody has argued that the smaller species has ever been called anything else than “swart renoster” (black rhino).

It seems to me, therefore, that the names “wit renoster” and “swart renoster” originated, simply, in the color difference between the species. Bwana, the black rhinoceros, was a noticeably darker animal than the white rhino standing a few yards away from him. Both animals had bathed in the same wallow, and were covered with the same dust, but the “white” cow was a light brownish-gray animal with an unmistakably chalky sheen to her, while Bwana was a dark, sooty gray. If you’d told a group of Muscovites with no special knowledge about African wildlife that one of those two rhinos belonged to a “black” species and the other to a “white,” 90% of them would unhesitatingly have picked Bwana as the black rhino.

While we were visiting with him, Bwana tried to open the latch on the boma gate with his pointed, prehensile upper lip. He obviously knew what he was doing, and might well have succeeded if the latch wasn’t secured by a padlock. He had gotten out, I was told, a few months before. Looking for company at the nearby house of his adoptive parents Clive and Conita Walker, he’d put his head through a bedroom window. The occupant had just left the bedroom, but it must have been a startling occurrence nevertheless, because the window happened to be closed at the time.

Bwana has also “played with” cars during his periods of freedom. Since I wrote this account of meeting and rubbing noses with him, he escaped again, damaged an aircraft on the reserve’s landing strip, and seriously gored a ranger the next day. It’s ironic that the people in Lapalala have become far more nervous about encountering this “tame” black rhino during one of his periodic escapes, than they are of meeting up with one of the area’s wild black rhinos who can (almost) always be relied on to run away when they sense the presence of our species.
