Ma’s Night Monkey: here’s the scoop


Night monkey populations are decreasing in the wild. In Peru, the species’ habitat has been largely reduced through conversion of forests for rice cultivation, pasture and more recently palm oil. In Brazil, deforestation is driven by the expansion of the agricultural frontier, mainly for cattle pasture and soy-bean production.
