For example somebody interested in antelope (some rancher in Texas?) who might import hirola from the rescue reserve in Tanzania, and import live mountain nyala, not trophies... Dream on.
Dream on indeed, but as somebody from Eastern Europe, you should be aware that especially Polish and Czech zoos have been bringing in a lot of interesting species in the past year, though far from all establish and if I am not mistaken Czech zoos have taken an interest in importing Giant eland, though whether that will ever succeed is a good question as the paperwork and legal requirements for importing hoofstock into the EU is a nightmare....
