Great news for the Critically Endangered Puerto Rican crested toad, as Detroit Zoo sent 6,855 tadpoles to be released into the wild, in Rio Encantado (Puerto Rico).

​

This release is part of the world's longest-running amphibian reintroduction programme, aiming to boost wild populations as part of wider conservation efforts by multiple national and international partners.

Twenty Vietnam pheasants bred under the European Ex Situ Programme (EEP) for the species were relocated to in-country breeding centre.
 

The species is potentially extinct in the wild as none has been seen since 2000, and therefore conservation breeding for future reintroductions are key to restore its populations in the wild.

 

This milestone is the result of collaborative efforts by multiple organisations, including several European zoos. 

Four male mountain bongos from the European Ex situ Programme (EEP) were returned to Kenya, to support conservation breeding efforts and future translocations within their native range.
 

The four bongos were carefully selected to improve genetic diversity and reproductive capacity of the population at Mount Kenya Wildlife Conservancy.

These collaborative efforts of European and Kenyan organisations aim to safeguard this Critically Endangered antelope.

🎉Over 100,000 captive-bred Bermuda snails were released into the wild, bringing the once-thought-extinct species back from the brink!
🐌The species is now considered safe and secure, a "once in a career" moment as described by the team behind it.
🤝This achievement is the result of collaborative efforts between the Bermuda government, organisation Biolinx Environmental Research and Chester Zoo.

Another milestone in the conservation of the European bison, with the release of 18 individuals in the Shadagh National Park, Greater Caucasus. This reintroduction project is jointly led by WWF Germany and Zoo Berlin, and 12 of the released bison (3 males, 9 females) were born in European zoos. The other six joined from the bison project in the Rothaar Mountains. 

 

​This species went extinct in the wild in the 1920s, and it was only thanks to the animals that remained in zoos, and collaborative conservation projects, including reintroductions, that the species bounced back and can again be seen across Europe and Central Asia.
