On the other hand, one could also argue, that zoos like Zlin, Plankendael, Gaiazoo or Opole are a whole category of zoos just like old, historic city zoos are. Mostly modern, spacious, high level exhibits without anything outstanding in terms of landscape. Just woodland or meadows with high quality exhibits and without (exaggerated) etho-kitsch. And i would argue, that Zlin is the best zoo within this category and therefore should be on such a list.
I like the reasoning, but I am not convinced by it. If anything I would choose Gaiazoo from that list as an example on how effective landscaping and naturalistic enclosures look when on a low budget. One could also argue that Obterre already functions as that place of the outer zoo with modern spacious exhibits without any kitsch or mock rock. It is an extreme example of that category though
To make space for a new zoo on the list, one had to go. It should not come as any great surprise as to which zoo would have to go.
There were a few candidates. There is the trio of Tierpark Chemnitz, Zoo Odense and Slimbridge WWT, whose inclusions were the biggest question marks at the start. But given that the reasons why I chose them for the list are still present, they remain on it as long as there is no better alternative.
While Zoo Magdeburg was mentioned most often as being the one suspected to drop out, it will remain. It is true that with a change of management, the focus on rare species is disappearing. But the other main reason to include Magdeburg was their very effective building technique where with little means spacious naturalistic enclosures are created, with attractive greenhouse style indoor enclosures for large mammals. Those examples like the tapir, rhino, chimpanzee and elephant house are still there and aren't going anywhere. How long Magdeburg can remain on the list is a question and when their marbled polecats pass away, that might be the final drop in the bucket. There is already a possible replacement though, but that place just isn't ready yet for inclusion, though I expect it to be in the near future
The unlucky loser of 2025 is Diergaarde Blijdorp. For anyone who has followed that zoo this century, that cannot come as a huge surprise. Only 15 years ago it was generally considered one of the very best all-round zoos on the continent. But financial troubles and a lack of vision mean that the zoo is steadily declining. It remained a clear choice for inclusion as it used to be one of the best geo-zoos around. But with the new masterplan, focusing on impact zones, rather than geography, that is no more. While the old part of the zoo is still clearly geographically ordered, the extension area is becoming a mixed bag. This change is most visible in the Oceanium. The whole idea was that it would be the first exhibit after the entrance, starting in Europe (because that is where Rotterdam is located) and it would take you on an aquatic journey to California at it's exit. That neatly fitted with the (North) American exhibits in that part of the zoo. But that is no more. The Caribbean reef inexplicably became a great barrier reef, the sea of Cortez (Mexico) is now an endangered species area, the California area is set to become a second North Sea and to top it of, there is now a Madagascar exhibit with ring-tailed lemurs too. The Oceanium is still a nice building, but it shows everything that is wrong with Blijdorp: no vision, no long term stability and no investments that are built to last. The Oceanium opened near simultaneously with the Ocean in Burgers' Zoo. But while the latter has hardly changed since it opened as it didn't need to, the Oceanium has lost all that made it unique. With the current management and bleak financial outlook, expect things to get worse before they will get better...
