What are the real effects we've seen so far? Even if minor it would be interesting to know.
Zoos have been exempt from all the bans, the regulation only calls for more work on education,conservation and research. So they can continue to keep, breed and exchange non-native animals. In practice it means that Barcelona Zoo is now doing more for conservation of native species and has stepped up their research. They are the leading Spanish mainland zoo when it comes to that, but not sure if they weren't already.
