What makes a zoo the best?

[ZooElephantMan]

So I was thinking about making a list of my top 20 zoos in the US, which I probably would never actually share out loud in order, but this is a list of them in a RANDOM order:

San Diego Zoo
San Diego Zoo Safari Park
Saint Louis Zoo
Henry Doorly Zoo
Columbus Zoo
The National Zoo
Cincinnati Zoo
Bronx Zoo
Fort Worth Zoo
Tampa Lowry Park Zoo
Oklahoma City Zoo
Woodland Park Zoo
Denver Zoo
Houston Zoo
Zoo Miami

I wanted to include Philadelphia zoo also but there was minimal room.

I know that whenever people make a list of their top favorite zoos in order, that it always inspires a lot of hatred and dismay and controversy, so instead of making a list that I would show you guys the order, I want you guys to tell me what you think makes a zoo "the best zoo" or qualities about zoos you think are the most important.

If there is a zoo that you guys think is good and isn't on the list, don't hesitate to mention it.

 

[Chimpangeek]

1. Exhibits a large collection of species from all over the world
2. Exhibits animals in an enriching and naturalistic environment
3. Participates in the breeding of threatened and endangered species and/or reintroduction programs
4. Engages and educates the public
5. Provides excellent veterinary care (especially geriatric)

 

[Kwambeze]

1. Animal Welfare (Including enclosure planning, animal condition...)
2. Goals for the collection (breeding, research, education...)
3. Aesthetic environment
4. Shows, displays, guides and other guest services
5. Range of species

Some of the things I look for in a good zoo
An aesthetic, naturalistic looking enclosure might just be the worst for the animal etc.
