Unexpectedly, they found that eight of the 13 oldest and five of the six largest baobabs had either completely died or had their oldest parts collapse.

Baobab trees have many stems and trunks, often of different ages. In some cases all the stems died suddenly.

“We suspect this is associated with increased temperature and drought,” Dr Patrut told BBC News. “It’s shocking and very sad to see them dying.”

The trees that have died or are dying are found in Zimbabwe, Namibia, South Africa, Botswana and Zambia. They are all between 1,000 and more than 2,500 years old.
