It's a big exhibit, Snowleopard. It's a big chunk of wooded hillside with a running water feature. They did a whole lot with just a little on that one by using the forest that was already there.
The tiger exhibit is 5400 square feet. When we built that part of the zoo we made every effort to keep as much of the vegetation as possible. The boardwalk is even built with some trees in the middle of it to maintain the forest canopy look. Contractors hated working around all of the trees but the final product was worth the hassle.
