Given that the alternative is their eternal absence, and the total loss of a species, options are quickly disappearing.

The best place is in the wild, but the worst place is as stuffed relics in museums. When their numbers dwindle low enough, I'd expect the species would be lost to unsustainable inbreeding producing compounded birth defects.

Incidental taming and domestication as a side effect of preserving the species might be better than no species at all. At least habituation to human contact is a reversible process. Rendering a species feral becomes an option, once their numbers are strengthened.
