Conclusions:
I) 6 facilities (DAK, Rum Creek, SD-WAP, LCS, Wilds and White Oak) are the major producers for the AZA/SSP program. I disallowed Fossil Rim to be called that as it has not bred their white rhinos since 2018 (a new male arrived in 2018 ... I think).
II) Few city zoos in smaller cities even have a succesful breeding group: only a shocking 7 and 2 of these helped out by introduction of a proven female from one of the bit achievers.
III) A further 16+1 MEX city / large conglomeration zoos have no breeding group (and often held them for years on end)
IV) There are 14 bachelor male groups, 1 non-breeding female group (elderly former breeders at Knoxville)
V) 5 zoos starting up with a potential breeding group.
Controversially 3 of these have changed from black rhino to white rhino in recent years (Atlanta, Columbia and San Antonio, the latter now exclusively so).
Further:
VI) the large CSC2 facilities seem to be working together to get some of their proven cows now out to non-breeding groups in city zoos (Tulsa, ) or larger ones with no succesful breeding till date (like Rolling Hills) and allow for space for the younger generations to go on to become broeders themselves.
VII) strangely enough - despite data to the opposite - many city zoos with no breeding have either maintained closely related individuals in bloodline (sometimes matrilines with F1 offspring, which indicative from the EEP/European program does have major stumbling blocks as a breeding strategy and does not correspond to wild-to-wild breeding where female breeding cows push out their daughters (who then closely associate with another proven adult breeding female).
VIII) another surprise remains that under achieving breeding groups tend to remain together far too long (Birmingham, Jacksonville, Memphis, Brevard, Indianapolis et cetera) even though pairs are incompatible as a pairing or in age behavioral wise (quite a few zoos have a sub-adult male with overly adult female cows that will not accept a male like that for a good number of years).
