@Yassa: I couldn't agree with you more. If the Copenhagen Zoo's elephant outdoor paddock really is less than an acre then it's a disgraceful size. The Taronga Zoo's elephant paddock has a lot of enrichment, but it is also far too small. To top it off, they are expecting a baby in Sydney and that will only increase the pressure on such a tiny exhibit.
It's interesting to see many North American zoos planning to open 2, 3, 4, or even 7 acre elephant enclosures, and the 7-acre North Carolina Zoo's enclosure just opened to the public a few months ago. There are countless zoos across the U.S. that wouldn't dare open a brand new elephant exhibit that is smaller than an acre, and even the Seattle Zoo's 1.5 acre enclosure has been heavily criticized for simply being too small. There are only 3 pachyderms and they don't even utilize the entire habitat, and yet it is regarded as being past its due date.
The Copenhagen Zoo's multi-million euro enclosure looks as if it will draw many visitors to the zoo, but will it be regarded as a world famous exhibit or something that is already past its prime? Of all the elephant exhibits found across Europe, can anyone here at ZooBeat name 5 of them that are actually world class? I know that in North America there are approximately 85 elephant exhibits, and perhaps only 5 are worthy to be called world class. Maybe only 2 or 3 are actually great habitats for elephants. Sad, sad, sad.
