Threats To Survival
The conservation status of this species was changed from near threatened to vulnerable in the 2008 World Conservation Union (IUCN) Red List because the species has declined at least 30% over the past 30 years (three generations) due to hunting and habitat loss. This is considerably better than the 1994 assessment which found them to be endangered, followed by the 2003 assessment which found the species to be near threatened. Although the conservation status has improved, actual population numbers are on a decreasing trend. Since these particular primates live only in white water flooded forests, they are very susceptible to human impact (i.e.: land acquisition for agriculture and/or pastures).
Forest loss and hunting are the two most prominent threats to Cacajao calvus. Between 1980 and 1990 it was found that an average of 15.4 million hectares of tropical forests were destroyed each year and the Neotropics are facing forest loss in areas such as the southern and eastern parts of the Amazonia. In 1997, the Amazon Basin experienced the highest rate of forest destruction of the remaining tropical rainforests worldwide. Logging of hardwoods is a major contributor to overall destruction as large-scale logging disrupts the continuity of forest canopies. Canopy disruption and forest loss directly affect uakaris because of their arboreal lifestyle and adaptations for seed food consumption. Additionally, Cacajao calvus populations are located so close to the Amazon River that there is a higher risk of human hunting from canoes and such to use the primates as a food source or bait.

Famous quotes containing the words threats to, threats and/or survival:
“Among the best traitors Ireland has ever had, Mother Church ranks at the very top, a massive obstacle in the path to equality and freedom. She has been a force for conservatism, not on the basis of preserving Catholic doctrine or preventing the corruption of her children, but simply to ward off threats to her own security and influence.”
—Bernadette Devlin (b. 1947)

“It is almost as if you were frantically constructing another world while the world that you live in dissolves beneath your feet, and that your survival depends on completing this construction at least one second before the old habitation collapses.”
—Tennessee Williams (1914–1983)
