Nigeria's wood industry is growing as trees are felled in the country's hinterlands and transported to Lagos. But the country's forests are disappearing.

One year on from the historic wildfires that decimated the woodlands of Gironde in south-western France, the bark beetle is adding insult to injury. Bark beetle larvae usually feed off the sap of dead trees, but after the fires left so many trees weakened, it's been a field day for the insect, which is now proliferating at an alarming rate. It's now a race against time to save what can be saved – to evacuate dead or infected trees from the area, in the hope of protecting their neighbours.
