Our Facilities

The Oregon National Primate Research Center (ONPRC) is located on approximately 165 acres of land just west of Portland, Oregon, within the Hillsboro city limits.  In addition to a variety of housing, the Center maintains dedicated surgery, clinical medicine, and pathology facilities and services.

The greatest population of ONPRC's nonhuman primates (NHPs) live in group enclosures:  indoor group housing, sheltered facilities with temperature-controlled indoor portions attached to outdoor runs, or in one of the one-acre, grassy, outdoor corrals enriched with play equipment.  The remaining NHPs are housed in appropriate caging as required by regulations and guidelines, and all animals at the ONPRC are housed within visual and auditory contact with others.  Every attempt is made to house animals in pairs whenever possible, and thus nearly all caged animals are pair housed.  To ensure compatibility and well-being, all NHPs participate in ONPRC's behavioral management program (see Behavioral Services).
