it is a matter of interpretation. The quote says in full:Yes it does. It says 'we are looking at larger vertebrates, including the 'gibbon ape' and the Saola, a rare forest -dwelling' etc. indicating these would be considered among species for the new 27 acre development.
“We are hoping for future growth and have a plan to develop another 27 acres of land.
The new area will feature animals from Asia where some species are under threat. We are looking at larger vertebrates, such as the gibbon ape, or the saola, a rare, forest-dwelling antelope which was discovered in Vietnam in the Eighties. Others we would hope to protect include the Sumatran tiger, Indian Rhino and Asian lion.”
It doesn't actually say they are getting them or even planning on getting them. You can either read it as "we are looking at getting these for the new area" or "Asian animals under threat are saola, gibbons, etc", especially because the following line says "others we would hope to protect..." which implies that he is actually talking about wild protection rather than captive animals. As dublinlion said, it is probably a case of the journalist fouling up the conversation.
In any case, it's a moot point because there's not a chance in a billion that they would ever be able to get saola.
