Some species that are super enabling would get priority though over other species. Those would include, Giraffe, Zebra, Lions, Meerkats, Tortoises, Kangaroos ect. All only really fit the enabling category, but there'd be an exception as a zoo wouldn't be a zoo without them.Dholes would be a great addition to Melbourne Zoo. I’m thinking Maned wolf would gain favour for exhibition in the Predator Precinct by virtue of being a South American species however. With the probable phase out of the coati, this continent will soon be unrepresented - while they have Sumatran tiger, Snow leopard etc. representing Asia.
Maned wolf were previously phased out of Melbourne Zoo’s collection, but you have to wonder how seriously they take this species criteria when they still have Slender-tailed meerkats, who are enabling, that’s it; Plains zebra, who I wouldn’t even consider enabling when there’s no foals in the herd; and were recently considering exhibiting Lowland nyala, which again aren’t enabling.
Other species like Binturong which were also recently phased out aren't as popular, so wouldn't really be a notable absence amongst most visitors. That's why I think their should be a sixth category too: Popularity.
