Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Captive breeding and reintroduction of primates into the wild: born and reared in cages One before-and-after study in Brazil found that most reintroduced golden lion tamarins that were born and reared in cages, alongside other interventions, did not survive over seven years or had a higher mortality than wild-born tamarins. One controlled study in French Guiana found that more squirrel monkeys which were born and reared in cages, alongside other interventions, died or were returned to captivity post-reintroduction compared to wild-born monkeys. One controlled study in Madagascar found that the diet of reintroduced black-and-white ruffed lemurs which were born and reared in cages, alongside other interventions, did not overlap with that of wild lemurs.

One before-and-after study in Madagascar found that most reintroduced black-and-white ruffed lemurs with limited free-ranging experience, alongside other interventions, died over five years. One before-and-after and site comparison and one before-and-after study in the Republic of Congo and Gabon found that most reintroduced western lowland gorillas with limited free-ranging experience, alongside other interventions, survived over a period of between nine months and four years.

One controlled study in Madagascar found that the diet of reintroduced black-and-white ruffed lemurs that were born and raised in a free-ranging environment alongside other interventions, overlapped with that of wild lemurs.

Two before-and-after studies in South Africa found that most reintroduced vervet monkeys survived over six months after being rehabilitated before release, alongside other interventions. Two before-and-after studies in the Republic of Congo found that most reintroduced chimpanzees survived over 3.5–5 years after undergoing pre-release rehabilitation, alongside other interventions. One study in The Gambia found that numbers of reintroduced chimpanzees that underwent pre-release rehabilitation, alongside other interventions, increased by 38% over 25 years. One review on bonobos, chimpanzees and gorillas in 13 African countries found that rehabilitated bonobos living in sanctuaries did not reproduce but the reproductive rate of chimpanzees was 14% and of gorillas was 2%. One controlled study in Indonesia found that Bornean agile gibbons that were rehabilitated before release, alongside other interventions, behaved similarly to wild gibbons. One controlled study in Malaysia found that numbers of reintroduced orangutans decreased by 33% over 33 years, despite orangutans being rehabilitated before release. One controlled study in Indonesia found that most translocated orangutans that were rehabilitated before release, along with other interventions, survived over three months. One before-and-after, site comparison study in the Congo and Gabon found that most western lowland gorillas that were rehabilitated before release, alongside other interventions, survived over four years. One before-and-after study in Gabon found that one out of two western lowland gorillas that were reintroduced died despite being rehabilitated, alongside other interventions.

Two before-and-after studies in Liberia and Congo found that most reintroduced chimpanzees that were fostered to facilitate reintroduction, alongside other interventions, survived over 1-3.5 years. One before-and-after study in Uganda found that a reintroduced chimpanzee repeatedly returned to human settlements despite being fostered to facilitate reintroduction, alongside other interventions. One controlled study in Indonesia found that reintroduced orangutans that were fostered natural behaviour, alongside other interventions, did not act more like wild orangutans than individuals that were not fostered. One study in Indonesia found that reintroduced orangutans that were fostered to facilitate reintroduction, alongside other interventions, fed on fewer plant species and spent more time building nests. One site comparison study in Vietnam found that all reintroduced pygmy slow lorises were assumed dead despite being fostered natural behaviour prior to release, alongside other interventions.
