At Manchester Museum and Bristol Zoo in the UK, and Nordens Ark in Sweden, they have successfully established a genetically diverse and healthy 'safety net' population of Costa Rican Lemur Leaf Frogs. A studbook has now been established and healthy animals are being bred and maintained within the programme as a back up to the wild populations in Costa Rica. This success, together with the "In-situ" conservation work being carried out has hopefully secured Costa Rican populations of the species for the future.
