Zoo Okapi Welfare: Managing a Stress-Sensitive Forest Species in Captivity

Okapis are one of the most stress-sensitive animals kept in zoos. Their welfare requires quiet, stable environments, low visitor density, and management protocols that minimise unpredictable disturbance.

Key Facts

Okapis (Okapia johnstoni) are the only living relative of the giraffe and are native to the dense Ituri Forest of the Democratic Republic of Congo, where they are listed as Endangered
Okapis are naturally solitary and cryptic — encounters with other okapis outside breeding season are rare, and they are highly sensitive to novel stimuli and social disruption
In zoos, okapis show clear signs of stress in response to loud visitor noise, unfamiliar keepers, sudden changes in routine, and close proximity to unfamiliar animals
Stress-related health problems in okapis include gastrointestinal disease, weight loss, and susceptibility to infection — all linked to chronic or acute stressors in the captive environment
Okapis are held in relatively few zoos globally due to their specialist requirements; successful facilities invest in low-traffic viewing areas, quiet keeper approaches, and stable social groupings
Dietary management is critical: okapis require high browse provision and are prone to metabolic bone disease if mineral balance is not carefully managed
The okapi is a flagship species for DRC forest conservation, and zoo populations contribute to awareness and funding for wild okapi protection programmes

Welfare Considerations

The okapi is an example of a species for which the welfare challenge in captivity is fundamentally about creating an environment calm enough to prevent chronic stress. Unlike more behaviourally flexible species, okapis are poorly suited to the noise, novelty, and social complexity of most zoo environments. The best okapi-keeping institutions structure their husbandry around minimising unpredictability: stable keeper teams, consistent routines, quiet exhibit design, and controlled visitor access. Measuring welfare through faecal glucocorticoid monitoring has helped identify which management variables most affect okapi stress levels, enabling evidence-based improvements. This work represents best practice in applying welfare science to a particularly sensitive captive species.

What You Can Do

Support zoos that participate in okapi Species Survival Plans and fund wild okapi conservation in the DRC
