This thread is dedicated to mainly new speciss that made it and began to increase in numbers so they will most likely last at least of a period in european zoological gardens An example is the yellow footed rock wallaby which did very well and can be seen in more and more institutions
Starting with masupials I think to call a species establishing it should breed at more than one place eastern quoll 11 Institutions, 6 breeding Kowari 11 Institutions, 4 breeding Common wombat (incl subspecies) 6 Institutions, 3 breeding Wollies and potoroos going strong Agile wallaby has a come back with 4 Institutions, but thanks munich good breeding (beside Magdeburg) Dusky Pademelon 11 Institutions, at least 4 breeding Eastern wallaroo 7 Institutions, at least 4 breeding Goodfellow tree kangaroo 10 Institutions, 4 breeding at least a few recent births Idk if swamp wallaby were rare but I see them more often than before White striped Dorcopsis 4 Institutions, 2 breeding Yellow-footed rock wallaby 12 Institutions, 5 strong breeding groups Heard that New guinean ground cuscus population is declining (only 6/15 breeding), bu hoped they revover themselves I cross my fingeea for bear cuscus and hope spotted may have a comeback Further I have read that some breeder managed to breed New guinean feathertail gliders But one never knows since illegal animal trader often use those terms to hide the original source
