I disagree; that would entail taking an exhibit for an extinct-in-the-wild hoofstock species that has a fascinating conservation story and that is the only extant member of their genus, and replacing them with a solitary species that is currently least concern and that most zoo visitors are already familiar with. Having one or two meese in that large habitat would also make it feel very empty, in contrast to the current deer herd. On many of my visits I’ve seen the deer wading and resting in the water, and it’s been amazing and unique to watch. Throwing this incredible species on the monorail would also sideline them, giving visitors much less time to be able to stop and watch the animals. In some cases, things like conservation status, rarity, and opportunity to teach the public about a lesser known and underrated species should trump geographic accuracy for the sake of geographic accuracy.
