A review by the American Association of Zoos and Aquariums concludes that a study of the species’ range in Kenya and Tanzania is flawed, and calls for a full scientific review.
The review says the study failed to consider species diversity and its impact on native animals, including Kakapo.
The study, commissioned by the Kenyan government, also says the paper did not assess the impacts of Kakapo removal on endangered Kakapo populations.
The AAAS report, which was released Thursday, was criticized by conservation groups.
The African Union called the review an “unacceptable” attack on the African zoos, which have been instrumental in the conservation of Kakapos and other wildlife in the region.
The Association said the AAAS review failed to properly consider conservation threats posed by the Zoos, including threats to wildlife, habitat loss and overpopulation.
It called on the Kenyan and Tanzania governments to take action to protect the species, and said it would call on the AAAC to review the study.
Conservation groups have also said the review fails to consider the effects of removal on the populations of the critically endangered African elephant, and also the threat of extinction posed by zoos.
