Apple ring Acacia

Big V

Boswell and Big V[1]  are the best-known elephant bulls in Mana Pools National Park. I recently reported about Boswell’s skills to feed on his hind legs[2], a rather unique trick. When we witnessed an elephant feeding on Acacia pods overhead and I reported in an earlier post[3] was Big V so I have already introduced both to you.

Mana Pools this August was extremely dry, as last year the rains were not good. For this reason the area looks more as it does towards the end of the dry season in November than it should be in August: a dust bowl! I believe that the animals are in for a tough two to three months until new rains arrive, if they do as these days weather patterns have changed.

Luckily for most of the animals in Mana the Zambezi River is there and, together with the pools that lend the name to the park, they provide water and fodder to keep the grazers going while the trees such as the apple-ring acacia (Faidherbia albida) will supply elephants with browsing. The animals that seemed hardest hit at the moment were the hippos that need to consume large amounts of grass so it was common to see them walking about during late afternoon already far from the water.

While checking in we learnt that lions had been spotted around an area known as Mana mouth. After recovering from the six-hour journey from Harare and, after unpacking and organizing our lodge, we decided to go there as it is close and the sunsets there are usually beautiful, even without lions! We never reach our destination as on our way we found Big V!

With him were, in addition to his usual young male retinue, a young female and its small calf, something unusual as large bulls tend to hang out on their own or with a few askaris[4]. He towered over the lot and he was clearly the undisputed leader of the group.

In an interesting contrast to his dominance over other elephants, Big V is an extremely relaxed elephant that allows the human observer to approach him either in the car or on foot. In contrast, the younger males can be more boisterous and occasionally perform threatening displays and mock charges that remind us that we are dealing with wild animals!

On this occasion it appeared that Big V was doing some “community” work by pulling down branches from an apple-ring acacia. Clearly, for the elephants this was the equivalent of eating at a Michelin-starred restaurant!

Although Big V was not standing on its hind legs “Boswell style” it stretched and reached high up the tree, to a height the others could not. As a result of its efforts large branches were brought down showing a great dexterity with his nose (it is easy to forget that he was breathing while doing this!) as well as the damage elephants can do to trees!

He will then fed on them, including the main branches, some of which were really thick! While Big V was eating, the other elephants were eager to collect any fallen pods or small branches but from a distance as Big V’s belly rumblings were sufficient to keep them all at bay! Well, not all…

The small female and her calf approached the feeding giant ignoring his rumblings. Expecting some rebuke we were surprised to see that they slowly got closer and closer  she started to steal bits of the branch to feed. The calf was also allowed into Big V’s inner circle and managed to pick some scraps. The large bull completely ignored them!

The reasons for this closeness I ignore but it was unexpected and we spent a few minutes watching how it developed. Spellbound with these interactions, we forgot about the lions and when the light was fading we returned to our lodge still talking about what amazing creatures elephants are!

Tree war

I said earlier that I am not a botanist and I am interested in the animal rather than the plant world. However, a visit to Mana Pools National Park would not be complete without spending time “tree-watching” . Here I present some facts that I trust you will find of interest.

It’s difficult to describe the various Mana Pools’ habitats. They range from clumps of green Natal mahogany (Trichilia emetica), Sausage trees (Kigelia africana) and Zambezi fig trees (Ficus bussei) to the rather sparsely populated Apple ring acacia (Faidherbia albida) woodlands, not to mention the areas of dense bush (known in this region as “jesse”) found further inland in the hillier parts. The result is an amazing, if rather fragile, bio-diverse habitat that many animals share, including more than 300 bird species. The above pictures, hopefully give you a better idea of what I fail to describe!

Although the experts list many tree species, the uninitiated (like me) feel attracted by the most striking ones. The Apple ring acacia trees are the main species of the riverine Mana Pools’ woodlands scattered all over the flat plains. They are large trees that, with time, develop a characteristic knobby trunk and as mentioned in an earlier post, they produce pods rich in protein that constitute important food for the animals during the dry season. Regrettably, a friend told me that for some reason they have stopped multiplying. This is rather surprising as the seeds are found all over the place.

The large Sausage trees were beginning to produce their strings of strongly scented dark red flowers. Many animals, including monkeys, also consume them. I remember seeing buffalo sniffing the ground for long periods at dusk at the campsite in Mana Pools on an earlier visit and to wonder what they were doing. It was only after a while that I realized that they were feeding on the Sausage tree flowers that had dropped to the otherwise dusty ground. Its fruits -rather large sausages weighing up to several kg- develop later on during the year, and various animals such as baboons, elephants and hippos consume them, while people also use them in beer brewing.

The Natal mahogany are large, dark green trees whose crowns in Mana Pools show a characteristic bottom foliage with an evenly trimmed horizontal lower edge, which is an example of the wild art of the master topiarist-browsers that feed on them, among whom are impala and greater kudu.

All trees complement each other to achieve this beautiful landscape. However, and perhaps surprisingly to the reader, there is a silent and long-term tree war being waged while we watch… I am not talking about Lord of the Rings’ Ents but rather a combination of several battles being fought by stationary trees since time immemorial. It all starts with a bird or monkey feeding on a fig and dropping its seeds in a suitable place up a tree, where a hollow filled with soil allows germination to take place.

The birth of a Zambezi fig tree.

A further close-up reveals the birth of a Zambezi fig tree.

Soon, an innocent-looking two-leaf seedling appears. After consolidating itself, it starts sending down aerial roots that surround the host tree and that will eventually reach the ground to bury themselves, becoming true roots. The fig tree uses the host to gain support and structure in its growth; the host is like a guiding stick similar to those used to support grapevines or tomato plants. In their quest for support and with their uncanny ability to survive in the most unlikely places, fig trees produce natural sculptural Masterpieces that occasionally damage ruins, which is an entirely different problem.

At some stage during the battle, it seems as if the two trees coexist naturally, adding great beauty to the forest. However, the process continues inexorably and the invader eventually strangles the host tree. This is purely mechanical as the pressure applied is such that it has the same effect as if the host tree would be ring-barked, interrupting the flow of water and nutrients between roots and the rest.

Luckily for some (in rare cases) animals may come to the rescue. The aerial roots are eaten by elephants and, in this way, these animals become an unwitting ally of the host tree, halting the growth of the fig and saving the host tree at least for a while.

However, this is an exception and the usual outcome is that the Zambezi fig tree becomes established, winning another battle.

Fig trees are beautiful shady trees with a great canopy that extends further than most trees, considering the size of their main trunk. This is often their weakness as, being soft, they often crack and fall which leads to the death of the tree.

Despite these battles that rage silently in plain sight, we should not worry as the outcome is by no means the doom of the striking Mana Pools woodlands!
