I don't know currently, but about 15 or so. I haven't been keeping track of giraffe births and deaths lately. All but one in the region descend from Orana's animals and are horribly inbred. The exception is Melbourne's female (imported in 1997 from the Netherlands), who has of course produced young herself with Orana-descended animals.How many purebred Rothchild's giraffe are in Australia approximately?
If I understand correctly, Makulu (1999) at Hamilton Zoo is the only Rothchild's bull in a New Zealand accredited zoo, while Orana has three Rothchild's cows?

Given the way generic animals have been added to "pure" herds such as at Orana, and now this mixing at Mogo, I'd say the ZAA has finally just decided to mix them all together anyway.
mixing the giraffes together is the best thing (if only because the Rothschild's in the region probably wouldn't be suitable for breeding into any other pure Rothschild's population elsewhere). They are never going to be anything other than display animals anyway. It is irritating, however, how the zoos deliberately frame press releases to imply otherwise.I guess with such a small population of purebred Rothchild's, maintaining pure herds would neccesitate excessive inbreeding if new imports are not impossible so with that in mind I agree the decision to mix all giraffes is the right one. I guess they will serve as an ambassador species that delights the customers, but serves no direct conservation purpose .
So in terms of the history of Orana...Orana had a male and (two?) females that produced several female offspring including Misha and Marama (sent to Perth) and three females that remained at Orana and bred with a new male, Harold?

Anyway, that aside, Orana had the original pair imported in 1982 and the first-born daughter of that pair also bred with the male - so one male and two females. After the death of the original male another was imported from Chicago in 1994.
Of the Orana-bred animals which ended up as Perth's breeders, female Misha went straight to Perth, female Marama and male Armani went to Melbourne and later to Perth (all in different years, not as a collective herd).
the Rothschild's giraffes in Australasia are in the same situation as Rothschild's giraffes in North America. They are not considered to be reliably pure because they originated from North America (except for the one female from Rhenen) - and, as with all the North American ones, they are listed in the studbooks as either "retic/roth" or "generic".To continue to cultivate a culture of hybridising a highly threatened giraffe species (!!! - given new taxonomy / genetics) is somewhat bizarrely puzzling. All the more so as alternatives exist to get a representative group of pure-breds by import thru 3-rd party states.
Didn't realise that Misha and Marama were full Orana sibs. Also thought they came together prior to opening of Savannah display. Reason for difference of births however is more to do with Misha being a top-notch mum and Marama being the opposite + not showing much interest. Her calf was hand-raised. Suspect PZ tried to get her mated again, but to no avail.Thanks for that information. I'd always assumed Misha and Marama went to Perth together but Marama going later would explain why Misha had multiple calves with their male, Anthony, and Marama had only one.
there's about seventy.Does anyone have an idea of how many giraffe there are in Australia?
It came up tonight in conversation I am thinking allot! Maybe 100-150.
it's a private facility owned by Alan Gibbs. He holds a few male giraffes and zebra.Can't seem to find info on Keystone is it a holding facility for Auckland Zoo?
Thank you.
Surprised no breeding group ATM in NZ.
The Chicago male was pure Rothschild's. He came froma different import to the bulk of the retic-roth giraffes in North America. It was much more recently than that when hybrid animals were merged into the Orana stock.The Orana Park stock was pure-bred rothschildi at the outset (the Rockton - ALS founders were derived from UK's Woburn Safari Kenyan rothschildi imports). The imported half-sibling pair (which shared the same sire) were bred to one-another. To be fair they tried their luck with a new import in 1991 (a male ex Fota Wildlife Park ex Ireland), however he never made it to adulthood and reproduction. The real rot started when they imported the Chicago Lincoln Park male in 1994 which was listed as a reticulata/rothschildi ..., but effectively was a hybrid of sorts. From then on it became increasingly precarious.
