Principal Drivers and Conservation Solutions to the Impending Primate Extinction Crisis: Introduction to the Special Issue

Nonhuman primates are facing an impending extinction crisis with over 65% of species listed as Vulnerable, Endangered, or Critically Endangered, and 93% characterized by declining populations. Primary drivers of primate population decline include deforestation, principally for industrial agriculture and the production of food and nonfood commodities, much of which is exported to wealthy consumer nations, unsustainable bushmeat hunting, the illegal pet trade, the capture of primates for body parts, expanding road and rail networks, mining, dam building, oil and gas exploration, and the threat of emerging diseases. Over the next several decades, human population increase, agricultural expansion, and climate change are expected to contribute significantly to the loss of additional suitable habitat and a reduction in the viability of local primate populations. If we are to avoid this impending extinction crisis, primate researchers must prioritize projects designed to mitigate the effects of habitat change on ecosystems health and biodiversity, and play a greater role in conservation and environmental policy by educating global citizens and political leaders. In addition, the international community will need to work with governments in primate habitat countries to expand the number of protected areas that contain primate species (94 primate species have < 10% of their range in protected areas). In this special issue of the International Journal of Primatology, we bring together researchers from a wide range of disciplines to examine the current and future threats to primate population persistence, and present local, country, and regional solutions to protect primate species.
