If these size standards were any smaller, giant tortoises would have to lie on the side permanently.
21.5 ha is not small for an urban zoo, but much of Moscow Zoo are several huge ponds. From what I saw, even so-called modernized sections are visibly too small. There are still small cages just few animal body length across, which disappeared from Europe some decades ago. I imagine if Moscow zoo wanted to become a modern zoo, it would need to redesign, demolish and rebuild whole sections and keep only few large ABC mammals. But Moscow has some breeding center on its outskirts, where they keep argali and whatever. I guess Moscow could become another city with a small central zoo and a huge landscape zoo on its outskirts - like Antwerp and Plackendael for example.
No it certainly isn't, but I imagine given the size (21.5ha as far as I can see) if they wanted to keep all the species they hold a. on public display and b. in spacious modern enclosures they would have to start stacking buildings on top of each other!
