I’ve heard from someone I know who works at the zoo that they want to conserve the park’s existing natural wildlife as much as possible, integrating other exotic species into the biomes already there. So zebras, giraffes, elephants, rhinoceroses, and the like would do fine, but carnivores have the potential to eat things that already call the park home. And they don’t want to eradicate any non-invasive species currently present; biodiversity studies have already discovered over 100 bird species, 5 bat species, and hundreds of turtles, snakes, lizards, frogs, salamanders, and invertebrates. I don’t know what they’ll do about the coyotes and foxes.
