There anywhere with the details of the Sumatran Rhino breeding program in historical context? What zoos had them and what problems did they experience, etc.? I know Cincinatti still has one and I think L. A. had them.
If the numbers rebound a little, I'd like to see at least one of the two species enter a breeding program, if not both, but both species' numbers are too low right now to risk it unless we really had a sure-fire breeding pair of Sumatrans for Cincinatti, since they have experience, but even that is probably too late.
At my most cynical, I'd like to think we can at least save one of the two species.
