Baobab trees can live for thousands of years, and many in southern Africa have died suddenly

the gist

Baobabs are medium-to-large deciduous trees in the genus Adansonia, with eight species native to Africa, Australia and Madagascar. Their trunks store water in pulpy wood, and they are among the longest-lived flowering plants. Their flowers open at dusk and last only about fifteen hours. Early in the 21st century, baobabs in southern Africa began dying rapidly and mysteriously. Blight or pests seem unlikely to have killed so many trees so fast, so some researchers have suggested mass dehydration as a possible cause, though the cause is still not settled. The genus itself seems to have originated in Madagascar.

how it works

Baobabs store large amounts of water in their thick trunks, which lets them survive long dry seasons. Their sudden die-off is still being studied, and dehydration under extreme drought is one hypothesis.

so what

Baobabs are a symbol of African landscapes, and their sudden die-off shows how climate stress can threaten long-lived species quickly. The mystery is an open scientific question with real conservation stakes.

fun fact

The baobab is nicknamed the upside-down tree because its branches look like roots.
