This study assesses the impact of hunting on the densities of nonhuman primates in two indigenous Tikuna territories (Mocagua and San Martín), overlapping Amacayacu National Park in the Colombian Amazon. Large-bodied primates were once favored prey by Tikunas, but are now rarely hunted owing to the diminishing primate populations. We evaluate the effect of a hunting ban on woolly monkeys (Lagothrix lagothricha) by the residents of Mocagua, using qualitative and quantitative methods.
