Ok this is a particular interest of mine and I am hoping that those of you who have closer connections with zoos may have some comment. There are theoretically two groups of giraffes in the Australasian region, Rothschilds and the hybrids. The hybrids are inbred and to try and rectify this problem, young male rothschilds are being used as the new blood. This is happening at Western PLains with Nakuru, Monarto with Tambo and Auckland with Zabulu.
Now to the Rothchilds, there are two bloodlines, descended from two males, Harold ay Orana and Anthony from perth. And this is where the problem occurs, two founders means that pure rothschild can only be bred for two generations before inbreeding starts to occur.
The second generation will soon be born in three different places. Perth, Orana and in a few years, Mogo. The next problem is that it doesn't seem possible that new blood will be able to be imported from overseas. So what will happen. Are we likely to lose the pure rothschilds from the region? Along with many other species such as pygmy hippo, bongo and both the tapor species.
What is the problem with importing giraffe into the region. It can't just be difficulties in moving the animals. Harold, Anthony and all the females were brought into the region in the last couple of decades. Are the zoos trying to find a solution to this or are they just going to muddle along and let the breed die out.
BTW, this will have an impact a decade or two on the hybrid population as well. All the giraffes being born in Australia at least are closely related. The two breeding males at Dubbo and Monarto are uncle and nephew. Their calves shouldn't be bred together.
