Seattle's elephant exhibit is a perfect example of how the "times they are a changin'" in regards to zoo management ideas. The 1.5 acre habitat opened in 1989 and was immediately given the AZA Award for Best New Exhibit and it must have seemed spectacular for its era. With the proliferation of fantastic elephant exhibits that have been constructed in the past decade suddenly Woodland Park has a once or twice a year protesting group and the elephant exhibit is clearly on the small side for such a great zoo. To make matters worse Hansa the 6 year-old died of the herpesvirus, Chai has been inseminated innumerable times and simply cannot get pregnant again, Watoto is an African elephant, and Bamboo is supposedly a volatile female who cannot be put together with both of the other elephants at the same time. She was even sent to Point Defiance Zoo for a brief spell but was then returned as she did not get along with the equally cranky females there. There is always an elephant separated from the other two, even though they can all see each other, and I've seen many signs of stereotypy from all 3 elephants.
A few years ago there were plans to partition off part of the elephant exhibit for Indian rhinos but that never came to fruitition, and in my personal opinion as soon as one of the elephants dies the zoo should send its remaining two away and have Indian rhinos on exhibit. Point Defiance is already going to phase out elephants for Indian rhinos and a breeding program would be easy to set up between the two zoos as they are only half an hour apart from each other and the current exhibits would be glorious for rhinos. Oregon Zoo is only a few hours away and that zoo already has plans and funding in place for a 6-acre Asian elephant habitat to be built in the next few years, with rumors of a 100-acre off-site breeding facility for elephants.
Detroit Zoo sent away its two elephants and there was a worry that attendance would drop and the public would stay away in droves. Interestingly enough that zoo broke its all-time attendance record 4 times in 5 years with zero elephants so I'm convinced that Woodland Park would not miss out by not having elephants and I don't believe that the zoo has the space or funding to dramatically overhaul its current enclosure. At the moment the zoo is doggedly committed to its elephant program but the "herd" of three is dysfunctional at best and the logical thing to do would be to phase the species out.
