Returning Primates to their Wild Homes

Releasing an ape or monkey back into the wild is one of the most satisfying aspects the Alliance’s work. It is also among the most complex parts of what PASA members do.

Our Impact

PASA members released over 150 primates into the wild in the last year. In addition, they monitor these animals and other wild-living primates, including 283 chimpanzees and 63 gorillas. Most monitored gorillas were reintroduced to the wild by the sanctuaries.

When are reintroductions possible?

Reintroductions are a great outcome, but not necessarily for every animal. So when a PASA member takes in a rescue, they evaluate whether the animal would be a good canditate for returning to the wild.

Sanctuary teams ask themselves:

  • Is the animal healthy? The age, gender, physical condition and overall health are important factors. Younger, healthier animals have a better chance of doing well when released.
  • Is the animal socially and emotionally able to live in the wild? Many rescued animals are severely traumatized and lack the social skills to thrive in the wild.
  • The availability of a release site with enough space, food, and safety to support the release. With habitat becoming scarce, there simply may not be sufficient space in which to release the animal or group.

Once the criteria have been met, there are many logistics involved, too. Getting permits to transport the animals takes time – all the more so if the primate is on the endangered species list, such as a gorilla or chimpanzee.
