You're asking questions that the two big sanctuaries in the country probably asked and solved when they opened their doors around two decades ago. The Elephant Sanctuary in Hohenwald, TN and the Performing Arts Welfare Society (PAWS) in CA, which started as a rescue for animals performing in movies and TV. They had a lot of interest--and new occupants--as activists pressured zoos to close their elephant exhibits and a large supplier of circus elephants was forced to relinquish a large number of elephants. Since then, however, their populations have been decreasing, and the few elephant exhibits that do close have been sending their elephants to other AZA zoos instead of sanctuaries. Those that are left in sanctuaries are older and are gradually dying. Certainly neither of these sanctuaries--one is 3,200 acres and the other has three different faciluties--would be able to procure donations and remain open if there were no longer any residents, and then activist organization's would have difficulty claiming elephants should be moved to Sanctuaries if none exist. This started to make me wonder recently if the activists are working closely with the Sanctuaries to keep them open. How? Well, if zoos will no longer send their animals to Sanctuaries, the only place to get animals is from circuses or private owners. I think it's entirely possible that the activist-sanctuaries have started some intensive efforts to save their organization's by approaching animal owners directly, offering large amounts to buy their animals. If the sanctuary population disappears, then Sanctuaries, and so do activist organizations, because they no longer have somewhere they can send animals they want out of zoos. I bet the efforts have been well underway to offer big money for circus owners to sell their elephants. There's another new elephant sanctuary ready to open in FL, but from where I sit, need for it is disappearing.
