Yes that's true, this exhibit was built back in 1988. If you see the wooden wall in the back, the original exhibit was open behind that wall. But altogether I would say it was at least 1/3 of an acre, probably a little more.
The exhibit looks to me more like a quarter an acre. It has since been renovated and now holds a male malayan tapir. It looks a lot nicer now, and is much better themed, instead of a dusty yard. The male here, Arjun, was moved in with the female, in the female yard.
