i beleive they are planning to expand, as the asian at sdwap are moving to sdz, when the elephant odessy exhibit opens. it is a really interesting concept. it is going to be the calafornian state, but 20 000 years ago, with tar pits, and bone digs etc. there will be asian elephants, in mixed species with brazillian tapir, cabybara, rhea etc. alongside jaguar, puma and californian condor. it's meant to be about the changing times, and the current rate of extinction, sounds great, and very large.
back to the wap, this means the 3 acre or so asian facilities will be freed up for africans (located side by side)
the largest ele facilities are the disney animal kingdon at 9 acres, followed closely by the soon to be opened Wantani Plains exhibit at NC ZOO. they have more than doubled tehre ele collection in the past 3 months, with 4 arrival, bring them to 7 eles, to bve put in a 8 or so acre exhibit, nxt door to the 30 axcre savannah, with 10 rhino, and 100 antelope. nc zoo is a little love of mine that i follow. i love it!
