I think the Congo exhibit is a very good model. It concentrates on a couple of species that need management and care, gorillas, okapis, for example, and, backs them up ecologically and educationally with smaller or abundant species. It presents the conservation picture in considerable detail, offers the visitor a way to actively contribute to its resolution. I think the Congo model can be greatly improved upon, but as a preliminary skeleton for some kinds of new exhibits, I think it’s a good model.
