The News story ‘Palm-oil boom raises conservation concerns’ (Nature 487, 14; 2012) wrongly attributed 27% of Indonesia’s deforestation to palm-oil planting. This figure was only for the area of Ketapang. It also said that this figure would rise to 40% by 2020, but that is the area in Ketapang projected to be given over to oil palm and is not due solely to deforestation.
