Some of Africa’s most famous trees have an unusual way of surviving dry conditions.
Baobab trees can store water in their large trunks. This helps them survive long periods with little rainfall.
Their thick trunks can become enormous. In fact, some baobabs look almost wider than they are tall.
How do baobab trees store water?
Baobab trees have thick, water-rich trunks.
Their trunks contain soft and fibrous wood. This structure allows the tree to hold water when it is available.
As a result, the trunk can change in size as water conditions change.
During wet periods, the tree can take in more water. It can then use stored moisture as conditions become drier.
This ability helps the African baobab tree survive in areas with long dry seasons.
Baobabs can survive harsh conditions
Baobabs grow across many parts of sub-Saharan Africa.
They are well adapted to areas where rainfall changes sharply between wet and dry seasons.
The trees also lose their leaves during the dry season.
This helps reduce water loss. Then, when conditions improve, leaves return to the branches.
One of Africa’s most recognisable trees
Baobabs are easy to recognise because of their unusual shape.
Their huge trunks support thick branches that spread across the sky.
Some people think the branches look like roots. This has helped give baobabs their famous nickname: the “upside-down tree.”
However, their unusual appearance is only part of their story.
Baobabs also provide food and shelter for animals. Meanwhile, people in several African communities use baobab fruit, leaves and other parts of the tree.
More than just a giant trunk
Baobabs show how plants can adapt to difficult environments.
Their large trunks help them manage changing water conditions. Their seasonal leaves also help them conserve moisture.
So, while a baobab’s giant trunk may look unusual, its shape serves an important purpose.
It helps one of Africa’s most recognisable trees survive long dry seasons.
