5,376 animals from 32 species or subspecies, cared for by 257 participants in 433 facilities – that is Citizen Conservation’s animal inventory as of 1 November 2025.

Scientifically based statistical tools can be used to calculate how many animals are needed in a conservation breeding programme to maintain it for, say, 40 years without a significant decline in the genetic diversity of the original animals. This results in target numbers – sometimes after technically justified modifications – which CC determines for each species and displays on the species pages of our website. We are already close to this target for the Mallorca Midwife Toad, Lake Pátzcuaro Salamander, Rio Pescado Harlequin Toad, Vietnamese Crocodile Newt, Madagascar Rainbowfish and Mangarahara Cichlid.

Over the past six months, we have successfully bred 22 of our species within CC. For example, the Mallorca Midwife Toad, the two Ambystoma species, the Rio Pescado Harlequin Toad, the Chinese Fire-Bellied Toad, the Fire Salamander, Titicaca Water Frog, Vietnamese Crocodile Newt, Madagascar Rainbowfish, Charco Azul Pupfish, Tiger Limia, and Mangarahara Cichlid. With other species, success has been sporadic or is just beginning, as in the case of the Guimbeaui‘s Day Gecko, where we are delighted to see an increasing number of small geckos hatching.
However, we have not yet had any success with the Loja Marsupial Frog and Smith’s Sabre-Toothed Frog. Unfortunately, we only have very few initial animals of either species. The Nguru Dwarf Chameleon is also proving difficult – while the reproduction of wild-caught animals originating from an impoundment at Schönbrunn Zoo has been successful, their offspring have not yet shown a willingness to reproduce. However, our experts are doing everything they can to ‘crack’ these species as well.
We are particularly pleased with the initial successes with Huu-Lien Tiger Geckos, Demonic Poison Frogs, Cielito, Phantasmal Poison Frogs, San Martín Fringe-limbed Treefrogs and Bintan Gouramis. There is also breaking news regarding Ziegler’s Crocodile Newt: the first larvae have now hatched at a private keeper’s facility, but after the cut-off date – so they will only appear in the next inventory overview on 1 May 2026. However, we hope that the first young animals of these still somewhat difficult species will soon be followed by many more!
