@petthebird:
Thank you. I do get you better now and I actually agree with some of your points while I still disagree with others. Let me try some responses:
There definitely are studies about pacing of carnivores that show the daily distances virtually don't differ no matter what (at least for some species). There also are studies/ experiences that show some species of carnivores require far less space than others. If you are into this stuff you may easily find out about this - I cannot remember any sources where I read it. Of course this should be no excuse for bad enclosures that don't allow for a broad reportoire of natural behaviour. I just wanted to relativize the pacing issue.
The Tierpark staff do employ food enrichment and rearrange the "furniture" as well as intoduce new stuff (I don't know the exact frequence of these procedures though). I also don't know if they employ any scent enrichment unless you count the dogs that are allowed in the park, the freely roaming species or the native ones

I was told the director does not enjoy any "artificial" enrichment though, particularly if it is visible (like colourful items, tires, large boxes etc.). So apparently it's a matter of policy/ philosophy rather than money or staff motivation (again I have no source for this condition). Instead the director apparently believes the composition of the groups and the upbringing of youngsters is the best enrichment. In a way he even seems to be right, for most groups seem very harmonious. Of course this radical position is still debatable, but it probably won't change until a new director takes office.
-The polar bear enclosure isn't that small in my opinion, even though the water part is far larger than the rest. Unfortunately they don't have different substrates. The bears do pace quite a bit and they even move their head in the typical way (PETA once arranged a video of it where they don't show any other behaviour). But in fact the bears also swim and rest a lot and especially the young female plays quite frequently as well and the bears also interact of course. In combination it may still be less than in the wild (e.g. no hunting), but I don't think they seem overly miserable or more so than in most other zoos. Enrichment is employed in the way mentioned above.
-The same goes for the spectacled bears. I have watched them sleep, pace, climb, play. They even interact with the visitors at time - rather curious animals indeed... And I can't see how their enclosure is overly boring (very spacious, different substrates, plants, pool many retreats, climbing structures, and I believe they even have a swing)
-The ratel diggs quite a bit by the way.The enclosure isn't that large, though. I wouldn't exactly call it smashing but it also isn't an empty box as make it sound. I don't know of any other ratels, so I cannot compare the behaviour. The civets always seemed normal to me and they do use the structures in their exhibit for climbing, hiding etc.
-The pachydermy building cannot easily be rearranged. At the time it even was quite state-of-the-art particularly for a GDR-zoo (be glad you don't know how the lived before). And while I agree they don't have large amounts of space inside they don't seem to suffer. They also do get out most of the year. And if you watched them outside (or when they bath inside) you will notice they are very active, peaceful and playful. As with other ugulates the large groups with several little ones and all the interaction are quite a joyful picture.
-The vari forest simply is an amazing(!) enclosure in my eyes. It is more than large enough which also holds for the trees by the way (check some youtube videos if you can't remember them which is difficult for me to believe). If you ever observed the lemures you also won't state again it's a bad or boring enclosure. They use the bushes, trees, fences, benches, visitors, you name it... Your criticism seems ridiculous to me, they aren't orangs after all!
-I'm not an expert on rodents or their behavious so I won't comment too much on these exhibits. They aren't huge (nor tiny) but seem well structured and quite sufficient to me.
-I never before heard that lack of substrate causes bad hygiene (the opposite used to be the case). I believe you that you saw what you tell (though I didn't as far as I can remember). But please believe me that I also didn't learn of many infected animals in the tierpark and I can't see how mice etc. can be kept from entering the boxes as long as far larger animals such as said primates etc. can get in.
-Offspring is published on lists at the entrance and press releases that can be accessed via the webside. There are some information on breeding programs on the regular signs and at the firefoxes (little pandas) you even find a decent display on their diminished habitat. There are larger boards for many zoologic-sytematic issues and other stuff. So it's again an exaggeration there is NO educational value.
-I won't comment on Swedish zoos as I don't know any. I only saw some huge exhibits with wooden bridges for the visitors that looked great. If this is more than an exception I certainly commend you guys over there, but the Tierpark still isn't as bad as your first impression may suggest. If you do actually return, please take some additional time and you will find groups that interact and even carnivores that don't pace but climb, play, swim...
