The herd will also provide an important contribution to the EAZA Ex-Situ Programme (EEP) for this species, which aims to maintain a healthy insurance population in captivity to aid in reintroduction efforts when necessary.

Giant burrowing frog breeding programme_

Melbourne Zoo Sets Up First Captive Breeding Programme for Rare Giant Burrowing Frog

April 22, 2021

The first ever conservation breeding programme for the giant burrowing frog has been set up at Melbourne Zoo (Zoos Victoria). Scientists from the zoo and partner institutions collected tadpoles from the wild and they will now study their development into adult frogs so they can optimise the breeding programme.


On top of being threatened by the chytrid fungus, habitat loss, climate change and invasive predators, this species has also lost great parts of their natural habitat due to bushfires in recent years. The captive breeding programme is an important part of integrated conservation efforts to restore and protect this species in the wild.

Loro Parque Sends Two More Lear's Macaws for Reintroduction in the Wild

March 10, 2021

Two zoo-bred Lear's macaws have been reintroduced into the wild, in Brazil, thanks to the efforts of Loro Parque & partners. This species is bred at the zoo under specific protocols and conditions, so they can more easily adapt to the wild once released. Once in Brazil, they are housed in large aviaries and go through "reintroduction training", so they adapt to the environment and further develop the necessary skills to survive.


Loro Parque had already sent six Lear's macaws for reintroduction, in August 2018!

Zoo Córdoba Receives Iberian Lynx Pair - Surplus from the Ex-Situ Conservation Programme for the Species.

December 17, 2020

The Zoo Córdoba has received a pair of Iberian lynx from the (Lynx ex-situ) breeding programme for this species. The two animals are unsuitable for reintroduction or breeding due to health and/or genetic anomalies but they found a new home at the zoo.


Only one zoo is actively part of the breeding programme
for this species (Zoobotánico Jerez) but a few zoos in Portugal & Spain house surplus individuals, alleviating space from the breeding centres and educating the public about the species and the threats it's facing.
