I have never been comfortable with the concept of reintroducing a species that we haven't directly observed. We can't predict the impact one may have on its environment or disruption to the food chain.
Reintroducing a species which we are familiar with, say after over hunting by poachers, is more likely to produce the expected results without complications because we have prior knowledge of that species role in nature.
