Giant baobab trees are icons of sub-Saharan Africa’s dry savannahs. Their vital statistics are impressive, they dominate the landscape and they provide resources for people and for many species of animals.

The African baobab (Adansonia digitate) is considered to be a keystone species with many mammals, birds, reptiles and insects depending on baobabs for food and shelter. The shade of the trees contributes to keeping soil humid, the trees contribute to nutrient recycling and they protect against soil erosion.

For people too, the leaves and fruits are very nutritious and more than that, all parts of the tree are used for their medicinal properties. Included among the beneficial medicinal characteristics are anti-inflammatory, anti-bacterial and anti-oxidant properties.

The bark is used for its fibre to make rope, mats, fishing nets and line, sacks and cloth. Remarkably the bark regrows so within limits it is possible to harvest the bark sustainably.

Large trees collect rainwater in clefts and hollows – providing water to travellers and local villagers – and in some instances the trunks have been hollowed out to act as reservoirs. The roots may also be tapped for water.

In South Africa the natural distribution of baobabs is limited to the northern part of Limpopo province, which includes the northern section of the Kruger National Park. However, I have seen a baobab tree in KwaZulu-Natal – it is a cultivated specimen that, surprisingly, is surviving adjacent to the multi-storey carpark of the Musgrave Shopping Centre in Durban! 

Elsewhere in southern Africa baobabs (Adansonia digitate) occur naturally in suitable habitat in Angola, Namibia, Botswana, Zimbabwe, Malawi and Mozambique, limited to hot, dry savannah woodland on stoney, well drained soils in areas that are frost-free. Baobabs cannot survive frost or water-logged soils and they are not found in areas with deep sand.

Above is a view over woodland in the northern section of the Kruger National Park where a baobab grows on a stony ridge. The nest that is visible at the end of one of the branches is likely to be the rather messy accumulation of sticks that form the communal nests of red-billed buffalo weavers (Bubalornis niger)

This tree in Kruger National Park is known as Van Weilligh’s Baobab, named for a surveyor G.R. van Weilligh who carved his initials on the tree in 1891. Red-billed buffalo weaver communal nests can be seen at the end of one of the right-hand branches. Elephants have stripped the bark from the lower section of the main trunk

On a dull overcast morning it was difficult to get a clear photo of a dark-coloured red-billed buffalo weaver against the mess of sticks comprising the communal nest. Several birds were coming and going, returning with sticks collected to add to the nest

Also nesting in Van Weilligh’s Baobab was a pair of mosque swallows (Cecropis senegalensis). In South Africa, these swallows occur only in the north-eastern Mpumalanga and Limpopo provinces as well as occurring in regions of other southern African countries. These swallows favour tall, dense, broad-leaved woodland and are often found in association with baobab trees. Mosque swallows have long forked tails and the long tail feathers of the bird in the photo above can be seen extending beyond the long wing tips

Although mosque swallows do build nests made from mud pellets in places such as under overhangs, some pairs nest in holes in trees, especially in baobab trees. In the photo above the nesting hole underneath a large branch in Van Weilligh’s Baobab is visible. Hole-nesting mosque swallows may use mud to fill up their nesting hole to make it the desired size

Above is the second bird in the pair we saw nesting in Van Weilligh’s Baobab. I assume that it is moulting as it appears to be lacking tail feathers! Mosque swallows are recorded as moulting during October/November and this photo was taken in November

Very young baobab trees do not resemble mature trees at all. Even the leaves are different in shape, being simple unlike the palmate leaves with their six or seven digits on mature trees. Seed production begins when trees are 8–23 years old, and trees are considered to be mature around the age of about 60 years. The typical lifespan of a tree is about 450 years, although with the use of carbon-dating a few exceptional individual trees have been shown to be as old as 2000 years. African baobab trees may grow to a height of around 25 m, but it is their girth that is truly enormous. As they grow older trees produce more stems that combine into the appearance of one trunk with the diameter of larger trees being 10–14 m (33–46 ft).

Yet another African baobab where the bark has been browsed by elephants

Elephants eat the nutritious bark of several species of trees. Unusually though the baobab has the ability to regrow its bark and can survive bark stripping both by elephants and people up to a point. If the bark stripping is within limits and the tree is not subjected to other stresses such as fire or extremes of drought or water logging it can survive.

This relatively small baobab tree growing next to the road near Pafuri picnic site in the Kruger National Park was perhaps blown over in the wind with the soil being moist after recent rains. I wonder if the road will be rerouted around this tree so that it has a chance of survival?

Provided enough of the root system remains in the ground, fallen trees can continue to grow and in time start growing vertical branches at 90 degrees to the fallen tree. However, some trees affected by water logging or other adversity can rot inside and then literally disintegrate and suddenly collapse.

The above photo shows the intact bark above the areas where the bark has been stripped by elephants. The bark of baobabs is fire resistant

A further incentive for elephants to eat the bark of baobabs is the moisture that the tree contains in its trunk. Baobabs are succulent in that they contain high amounts of water in the trunk and branches, storing water from the rainy season for the tree the draw on in the dry season. In times of drought elephants are drawn to eat into the fibres of the trunk to obtain its moisture.

This tree in Kruger National Park is evidence of how far elephants can go into a tree in search of the moisture held in the trunk. Obviously this level of damage weakens the tree. In an effort to protect the tree large sharp stones have been placed around the base of the tree to deter elephants from approaching the trunk

Viewed from the other side the tree looks relatively healthy and it was flowering and producing fruit when we photographed it in November 2021

Also on the same tree, the leaf growth was advanced compared to trees in other areas, perhaps due to differing localised early summer rainfall. A woodland kingfisher (Halcyon senegalensis) spent time perching in the shade probably scanning for food. Woodland kingfishers make their nests in holes in larger trees

Red-billed buffalo weavers were busily bringing sticks to the large communal nests in the baobab tree, activity interspersed with noisy defensive and breeding displays

The fruits may be round or cylindrical. The shell is very thick and hard. After ripening, the fruits fall to the ground. By then the flesh has dried out into a crumbly powder and the hard seeds remain in the intact shell. Animals such as elephants are able to crack the shells and eat the fruit. Elephants act as important seed dispersers – the seeds pass through their digestive tract and are deposited in the dung. The digestive process activates the seed and the dung provides a fertile environment for the seeds to sprout and take root. Baboons too are significant seed dispersers. Fire can also stimulate seed germination.

Fallen fruits are collected by people living in the vicinity of baobab trees. The dried pulp can be ground into a powder that is dissolved in milk or water to make a nutritious and tasty drink. The pulp can also be used as a thickening agent and as seasoning.

The seeds are edible and may be roasted, boiled, fermented or dried or ground into a powder. The seeds can be used to produce an oil which is gaining in popularity for use in personal care products for skin and hair treatments.

Increasingly there has been a commercialisation of baobab products for export. Gus Le Breton a.k.a. The African Plant Hunter argues that harvesting fallen fruits for commercial processes brings much needed income to rural communities in his native Zimbabwe in regions where subsistence agriculture is tenuous at best in drought prone areas. Realising the commercial potential of the baobab fruits not only improves the income of rural communities but also leads to the protection of baobab trees and habitats, which are of significant ecological importance.  To watch Le Breton talk about the Baobab Superfruit see his video here.

Le Breton’s Zimbabwean company B’Ayoba has teamed up with Limpopo-based EcoProducts founded by Dr Sara Venter (see also Baobab Foundation) to form Baobab Exports, which claims to be ethical and sustainable with all products traceable to source. Among the benefits of their programmes they list fair incomes, environmental protection, social programmes, empowerment of women and the formation of farmer cooperatives that adhere to certified organic practices.

With so much distressing news currently, it is good to read of positive initiatives such as these.
