There are already numerous species kept in zoos which are now extinct in their natural state and realistically speaking there are likely to be far more of these housed in the future as the biodiversity crisis intensifies. The purpose of this thread is for zoochatters to highlight, discuss and compare the way that zoos keep and display / showcase zoos species now extinct in the wild taking into consideration these factors : * Enclosure design - Husbandry / needs of animal , enrichment, general aesthetics. * Educational value - Information signs, interactive displays (audio-visual etc), environmental education / conservation related talks. What are some examples of the best enclosure / exhibit design that you have seen at a zoo for a species now extinct in the wild ? Did the educational content and signage showcase effectively the plight of the species well enough in your opinion ?
