Nine of 13 of Africa’s oldest and largest baobab trees have died in the past decade, it has been reported. These trees, aged between 1,100 and 2,500 years, appear to be victims of climate change. Scientists speculate that warming temperatures have either killed the trees directly or have made them weaker and more susceptible to drought, diseases, fire or wind.
Old baobabs are not the only trees which are affected by climatic changes. Ponderosa pine and Pinyon forests in the American West are dying at an increasing rate as the summers get warmer in the region. In Hawaii the famous Ohi’a trees are also dying at faster rates than previously recorded.
There are nine species of baobab trees in the world: one in mainland Africa, Adansonia digitata, (the species that can grow to the largest size and to the oldest age), six in Madagascar, and one in Australia. The mainland African baobab was named after the French botanist Michel Adanson, who described the baobab trees in Senegal.
The African baobab is a remarkable species. Not only because of it’s size and lifespan but also in the special way it grows multiple fused stems. In the space between these stems (called false cavities) bark grows, which is unique to the baobab.
Since baobabs produce only faint growth rings, the researchers used radiocarbon dating to analyse samples taken from different parts of each tree’s trunk and determined that the oldest (which is now dead) was more that 2,500-years-old.
