How are the nonhuman primates housed?
The Oregon National Primate Research Center provides social interaction for all nonhuman primates, except when concerns about monkey health and well-being or experimental needs would make social housing impossible.
The Center pioneered social housing of nonhuman primates in the 1970s, when it constructed several 1-2 acre, outdoor corrals for groups of 80-100 monkeys.
In the mid-1990s, after completing a 10-year project of creating a pathogen-free colony of monkeys that is unmatched anywhere in the world, the Center initiated efforts to increase social housing, including an ambitious program of constructing group housing facilities. At the same time, it began converting existing single cages to pair cages and training a large number of singly caged monkeys to live compatibly with companions. The Oregon National Primate Research Center continues to socially house nonhuman primates in pairs or groups unless research requirements prohibit.
