A lot of things you can do for special events can be done under that. I brought in new animals and paired animals that hadn't been paired. I spent the past year refining things because the zoo is starting new changes very quickly. AZA stands for American Association of Zoos and Aquariums. That is THE standard for zoos - that is what measures a zoo.
Every zoo tries to achieve that.
The federal government does not consider you a zoo until you have AZA accreditation. There are about 3000 zoos in the country. Out of that 3000, only about 180 are AZA accredited.
