Yeah - it does seem weird that there's been a gradual shift in favour of Asian elephants. Is this just a coincidental thing?
I think this is replicated across captive populations generally. Asian elephants have always been more common, longer-lived and more likely to have been managed by free contact. It may be coincidental but almost all the very successful African groups in Europe were (Howletts, Schonbrunn, Berlin) or still are (Boras, Wuppertal) managed under free contact. I believe WMSP was too and are only transitioning now they have a new facility that allows for protected contact?
I'd say Buta was probably ailing well before her arrival at Noah's Ark
Knowsley's elephants overall died prematurely (the record being 37 for one cow who died in 2004), but worth remembering these arrived in the UK as cull orphans on the whole. For a single cow to be moved to Noah's ark, it's likely there were compatibility issues which would have of course increased stress in a non-integrated animal, or limit paddock access if she couldn't be mixed at Knowsley. However, given Latabe died very recently at WMSP at 28, potentially the (acceptable) stress of a move to a new facility (even at the same site) and routine could trigger underlying health problems that may not have surfaced for some time had nothing changed.
Well bintarong said the plans is for WMSP to have the breeding herd of African Elephants so that they can breed and they can do their bit for the European Breeding Programme
I think this is as applicable to WMSP as it is to Noah's Ark, but for holders of African elephants there are virtually no available cows in Europe of breeding age not already either part of a matriarchal group (and so shouldn't be separated) or unlikely to be let go by the institution holding them. The only unbred cows not already part of a matriarchal herd who are still young enough to conceive are the six at Valencia. There's also Sweni at Wuppertal and Numbi at Schonbrunn, both have calves but are living with unrelated matriarchal group, I don't know if there are plans to end these slightly risk setups and even if they were to be moved I'm sure there would be zoos already higher up the queue than WMSP unfortunately, maybe not. But I suspect integrating other breeding-age cows is also more difficult than one or two post-reproductive females. There are a couple of breeding cows at Cabarceno who may also be living separately from the main group.
That being said, if WMSP are able to recall Jack or Tooth, two of the few active breeding bulls in Europe, this may shift whether the EEP are willing to relocate any viable cows to this site should any become available from the very small pool remaining.
