OK, maybe there...
Awhile back I recall musing on how the biggest problem of recreating the Mammoth could be where to put it. This would probably be it, a project which has been going on in Siberia for many years has recently released a kickstarter (Pleistocene Park) to help fund the recreation of an environment more conducive to keeping the permafrost permafrozen than things are at the moment. And mammoths would be a key part of the faunal composition if they can get them - maintaining and increasing grasslands takes a lot of fiddling, and knocking over trees to keep the taiga at bay is a pretty elephantine behavior.
Of course there's still that little engineering problem: First clone your mammoth. :) And also of course, one mammoth won't help much - you need a species who will breed true, and the ability to create social groups - like us elephants learn a LOT of what they need to know from the other elephants.
