Beetle infestation threatens Johannesburg’s forests

Johannesburg is home to one of the world’s largest urban forests, but it's come under threat from a tiny beetle. About 200 species of trees - many of them indigenous to South Africa - are afflicted with the pest and the fungus it carries. As scientists desperately look for a solution, many of the city’s trees are dying and experts are concerned the infestation could move from the forest to croplands next.
