Long story short, things didn't go as badly as they could have thanks to the EAZA and WAZA intervening. But the BCN zoo's progress is stagnant, and still heading un weird directions, because they still have people in power at the zoo who are zoo-haters... And I often realise that the zoo could be amazing, but the city itself is unfit to have it due to how ingrained anti-zoo sentiments are in society.
Thanks for the explanation. I had understood that the initial conditions of the ZOO XXI model (no more exotic animals and an end to participation in ex-situ species conservation, limiting the zoo to thr breeding and reintroduction of native species) had been modified after deliberation in the city council and that the zoo was to focus on Spanish and Mediterranean species as well as endangered animals form other parts of the world that are part of a conservation programme; that subsidies had also been allocated to facilitate these developments and that in the end only a few larger species (e.g. dolphin, rhino) would be phased out. But I have never been there before so good to hear from someone who knows the garden better.
