Bat Caves and Lemur Woods

[zooman64]

There is a trend in zoos at the moment for walk-through bat caves and lemur woods and for wallaby walk-throughs (the latter nearly always for the common and ubiquitous Red-necked Wallaby). But can anyone tell me which zoo originally had the idea for a walk-through bat exhibit and when, and which zoo was responsible for the first ever walk-through lemur wood?

which zoo was responsible for the first ever walk-through lemur wood?

I would think Apenheul in the Netherlands.

It will be interesting. I have copied the following from the Apenheul web site.

Revolutionary
Apenheul began in 1971 as a small but revolutionary zoo, the first and only zoo in the world(!) where monkeys live free in the forest but are also free to walk around the visitors. The zoo began with the woolly monkeys, the spider monkeys and a few other small species. In a short period of time it was proven that not only the visitors, but also the monkeys were content with this concept. This freedom allowed the animals to form ideal social groups and to reproduce perfectly. "Quote"
