So apparently the first three Maned Wolves in Australia came to Perth Zoo in 1981 from Berlin Zoo & Dortmund Zoo in Germany (source:
Ecology and Conservation of the Maned Wolf: Multidisciplinary Perspectives edited by Adriana G. Consorte & Co 2013). Apparently 15 imports from Europe, Nth & Sth America went to Australia (all captive born/ also not sure if PZ's original 3 are counted so could be 18 individuals) but apparently between 1983-2013? at least 72 offspring have been born in Australia (sadly only 28 surviving past 1st year though). Apparently 6 institutions in Australia have kept them and as this was published in 2013 I figured Altina, Western Plain, Melbourne, Perth, Taronga and Adelaide would likely be the six mentioned.
Apparently the first four pups born at Perth Zoo in 1983 did not survive but Tetrapod has mentioned that PZ had the most successful breeding program for them in the 1980s so I gather later litters mostly thrived.
