Some notes since you marked a couple as Provisional but not everything that is - I've added on where applicable and bolded everything with a signature program. Cavendish's Dik-dik and Baird's Tapir are removed as they are not an SSP.
Leaves us with 17 Provisional SSPs to 11 Signature SSPs... and as far as Signatures go, Pygmy Hippo and Malayan Tapir are propped up by Rum Creek, and roughly half the Takin population is at The Wilds.
Earlier in this thread, I mentioned how the AZA restructured the Species Survival Plan (SSP) system in 2022/2023. The restructuring made the eligibility criteria for a taxa to become an SSP significantly more strict, including firm mandates for known pedigree/genetics in the population and increased the minimum number of holders required from 3 to 15. The intention here was to make the SSPs exclusive to the most well-managed and sustainable populations. The intention was not to force the phase-out of all other species, but rather to lessen the management criteria and allow zoos who wanted to focus on other species do so without adhering to SSP requirements (namely pedigree/genetic testing and forced pairings). The major fault of this change imo is that the AZA did not come up with a new management plan, or at least formal category, for these dropped SSPs to fall into. The result has been the vast majority of animal programs being dropped from SSP eligibility, regardless of popularity and demand, and left many in the limbo that is "studbook only" or "TAG-monitored".
To highlight just how big of an impact this has had on AZA biodiversity, below is the list of ungulate programs that were killed with the reorganization:
-Barasingha SSP
-Bactrian Deer (studbook cancelled)

-Turkmen Markhor SSP
-Transcaspian Urial SSP
-Common Eland SSP
-Lowland Nyala SSP
-Greater Kudu SSP
-Sitatunga SSP
-Roan Antelope SSP
-Sable Antelope SSP
-Impala SSP
-Eastern White-Bearded Wildebeest SSP
-Ellipsen Waterbuck SSP
-Nile Lechwe SSP

-Lowland Anoa SSP
-Plains Bison (genetically-pure; candidate program cancelled)
-North Sulawesi Babirusa SSP*
-Panay Warty Pig SSP
*Added back as a Provisional SSP in 2025.
To be abundantly clear, these changes do not inherently mean the AZA has switched these species to phase-outs, it just means their SSP programs have been cancelled. I believe all of the above taxa still have TAG-monitored studbooks for the time being unless otherwise stated. It should also be mentioned that brocket deer and serow were absolutely a dead-end anyway. The problem here lies in the fact that the mindset built-up over the past couple of decades is that, if it isn't SSP eligible, it isn't sustainable. As mentioned by myself and others in this thread, many curators and directors prioritize taxa with SSP programs over all others to the extent that some may completely overlook anything that is studbook only. Zoos love putting the little SSP symbol on their signage, it ties in with their conservation message. Species booted from the SSP will absolutely be viewed as less of a priority taxa to zoo personnel (especially those with less of an animal background) than those with that status. Equally, the AZA/TAGs will promote SSP programs over those that are simply TAG-monitored. This system of SSP vs TAG-monitored has proven detrimental to the promotion of the monitored studbooks, so why the AZA decided the solution was to increase the number of programs that fall into this category is beyond me. This is why I think a category besides "TAG-monitored" or "studbook only" is necessary and, imo, it should have been the SSP definition that remained broad and a new, more exclusive category should have been created for the more stringent requirements. Or, we should just be letting zoos manage populations and promote endangered species equally wherever possible.
Of course, individual zoos/curators can still make up their own minds and institutions can still manage studbooks no longer sponsored by the AZA/TAGs. As such, the responsibility does not lie solely with the AZA. What I see is an inherent lack of education on the part of the TAGs to properly promote these "lower priority" programs. Rather, the concept of a "lower priority" program should not exist, or should be reserved for species that are simply not endangered / can be reacquired easily. If a taxa is struggling, it seems counter-productive to me to view the solution as lowering awareness and institutional priority for said taxa.
Below is the list of continuing ungulate SSPs:

So are Baird's Tapir and dik-dik only studbooks again? I know dik-dik was dropped entirely in 2020 but supposedly picked up again in 2023.
It is hard to keep track so thank you for the edits!
are african buffalo allowed? do we know how many holders for african bufalo? How do zoos think african hoofstock exhibits can do without african buffalo?
IIRC, the zoos that do have them are really dedicated to having them and are still breeding them.There are only 4 AZA with African Buffalo and that's been the case for quite some time, so really losing them wouldn't be a hit to African savannas. Most places sub in the more even-tempered Ankole/Watusi for African cattle.
Brookfield expressed interest in getting them in their master plan.IIRC, the zoos that do have them are really dedicated to having them and are still breeding them.
I do wish more zoos would get African buffalo as they're truly fascinating animals. I get that they're just cows to most people but that's on zoos for not hyping them up
I am totally with you there, they are so cool! Honestly, I prefer seeing them to white rhino, as the rhino have become so common in AZA zoos that I visit.IIRC, the zoos that do have them are really dedicated to having them and are still breeding them.

Additionally, what could the public do to protest AZA/zoo mismanagement?
That’s the problem, the public doesn’t care unless it’s something popular like elephants and big cats. To the public the zoo tends to be that place the school brings you for a field trip or a place to bring the kiddos. Other than the guest pleasers the animals there are just there to be confused for the wrong species, just be dismissed as a mere turtle or deer, and forgotten after the visit. If society cared about zoos and the species diversity sooner then there would have been an uproar against species reductions and trade laws that play a role in said reductions sooner.
I'm curious, what kind of background does it take to work in zoo management? The types of roles that are currently held by people who aren't so considered with conservation and biodiversity and heterogenous exhibits. How does one work their way up to the ability to direct a zoo in a way that does not prioritize the animals or the alleged mission?
I ask this as someone who is interested in changing careers, moving to San Diego, and going back to school this fall.
Additionally, what could the public do to protest AZA/zoo mismanagement?
Is there a reason former AZA personal would want to work for such a company? From what I have seen and heard seems very far away from what genuine animal and conservation focused people would want to be apart ofYeah, Steve went from SDZSP to Dallas with the vision of revitalizing their hoofstock collection, but was sadly pushed away from there by non-animal centric administration, too. After that I lost what little touch I had with him but I know he went to operate one of the newer Texas safari parks (whatever one Virginia owns; Zoofari?) before surprisingly taking a job at Colossal Biosciences.. Oddly, he's not the only zoo person I know of who left the AZA and ended up at Colossal.
~Thylo
$$$ is probably the main reason. Colossal is doing some legitimate research as well, but mostly it is animal adjacent and has cash to pay. The animal world, even the AZA world, is tough, especially on entry level and mid-level management people, long hours and comparatively low pay gets rough after a while.Is there a reason former AZA personal would want to work for such a company? From what I have seen and heard seems very far away from what genuine animal and conservation focused people would want to be apart of
while SwampDonkey already gave a great primary reason I do have a secondary reason which may come off as a bit speculative.Is there a reason former AZA personal would want to work for such a company?

I did read on to your later discussion about SSP vs TAG-monitored and studbook cases. It was suggested some time ago to me was that the "Consortium" management option would act to supplant the smaller SSPs that were eliminated by allowing these zoos to collaborate on these smaller populations directly without having to go through the same level of internal regulation and overview as a traditional SSP. There was also discussion that this would allow more freedom for better public-private cooperation. Has this approach failed to yield the results hoped so soon, or are we discussing the failures of the previous approach and are still awaiting how the new one might pan out? The fishing cat example in particular makes me wonder.With each redefinition of the "Species Survival Plan" (SSP) model, more and more species have found themselves excluded, unadvertised, disenfranchised, and ultimately ignored/forgotten. It effects all reaches of Animalia, but most notably in recent years North American primate and hoofstock populations have taken a massive blow.
There are a growing number of curators and even zoo directors out there in AZA zoos that are simply not interested in working with or promoting any species that is not an SSP or otherwise AZA-sponsored. Combine that with the fact that the AZA redefined the SSP program for, what, a third time to narrow the qualifications to already popular and well-established species (increasing the qualifying minimum number of holding institutions from 3 to 15). It's an absolute disaster.
That's a very alarming anecdote that should give anyone pause. Was Dan Ashe's position and views on these matters known when he was selected? How did he reach this position if so? Is there a term limit on the position or a method for removal, even if is unlikely to be used? Did the hoofstock keeper describe him this way as a consequence of his leadership (only two years in at the time!) or based on actions known prior to his selection to the position?But considering the fact that Dan Ashe, CEO and President of the AZA since 2016, simply does not care about nor does he think zoos require biodiversity in their collections, and it's no surprise that the situation is getting worse and worse. I remember back in 2018, I met one of the head hoofstock keepers at the LA Zoo. She described putting Dan Ashe in charge of the AZA was like handing the keys over to the 'enemy'. I was optimistic that she was exaggerating and that zoos like LA, the San Diegos, Bronx, etc. would continue pioneering for lesser represented yet highly endangered wildlife. Sadly, it seems I underestimated just how much Dan Ashe simply does not care about the animal aspect of zoos (an increasing and extremely worrying trend across zoo leadership in both North America and Europe) and I underestimated just how many zoo folk would simply give up.
This is the big shocker for me. In years and years of discussing "phase-out" species on ZooChat, something I was very passionate about when I was new to this board, I was told several times by multiple members, many with more 'zoo world' experience than me, that zoos were absolutely not punished for refusing to phase out taxa and that it was only a recommendation, and the AZA had no way methods to "enforce" these as rules. This had a big impact on my thinking for a long time and caused me to ease my initial criticism of homogenization and phase-out programs. That someone, let alone someone of Metzler's position and stature, could be intentionally forced out from the organization specifically for refusing the phase-out rules is appalling and challenges so deeply one of the foundational lessons I had taken on this website.What does it say about the state of modern AZA zoos when management--most, if not all of which have zero animal keeping experience--force individuals such as Steve Metzler (formerly SDZSP) out of the AZA entirely for refusing to not phase-out taxa the AZA does not want to promote.
It seems to me that the concept of "genetic metrics" and the relationship with captive sustainability is the root cause of this problem, for better or for worse, and its subsequent negative effects. You may have some insight that the chicken came before the egg, my experience is much lesser, but in my long time on Zoochat I became very familiar with the argument that where similar subspecies exist in captive populations, it is better to phase out many so that one species may prosper. It was often merely stated that the AZA could only "support" one or two members of a group, and therefore would select either the more endangered species if there were multiple viable populations or focus on the most clearly viable captive population. Large, solitary megafauna in particular were suggested to need the maximum possible number of holders to reach sustainability. Emphasis on "number of holders" is part of why I became somewhat fixated on the lack of newer large facilities in the United States - no potential to increase holders. Asiatic black bears were depicted as competitors to sloth bears, taking "resources" that could be going to the other species - although the losses of Asiatic black bear at Henson Robinson, Milwaukee or Lincoln Park Manitowoc have not been shown to help exotic bears, unfortunately. There is also the giraffe situation, where it was long expected zoos would phase out hybrid giraffes and fully transfer to Masai giraffe's pure bloodlines, which is now looking unlikely to ever reach a complete changeover due to genetic factors within the Masai giraffe population, and remains complicated and controversial as seen with the recent hybrid births.I doubt we'll ever reach a complete changeover.The modern AZA does not concern itself with preserving endangered species when it's hard, it concerns itself with preserving whatever populations are already large and healthy because that's good publicity. The modern AZA does not concern itself with good taxonomy, it concerns itself with whatever cross-breeding looks good for their genetics metrics.
The Brazilian government entrusted us with endangered Brazilian Ocelots, but today the studbook recommends cross-breeding with generic and South Texas cats because "genetic diversity". The AZA maintains the only captive assurance population of the undescribed Panay Warty Pig (S. cebifrons ssp. nov.), but today the TAG either wants them crossed with Negros Warty Pigs from European zoos or phased-out entirely because "genetic diversity". Transvaal Lions (subspecies krugeri under traditional taxonomy, melanochaita under modern) are now being admixed with a male from Sudan (nubica under traditional taxonomy, leo under IUCN) who has a top breeding priority recommendation because "genetic diversity".
My understanding is that this often occurs for financial purposes - where a non-zoo person is placed in charge to bring a facility that is having financial problems back into a financially viable position, so that theoretically that money can be used to reinvigorate the animal collection later, possibly by a successor who may be more focused elsewhere. I know it has once been mentioned this was the case with some of San Diego's leadership. There was a discussion that the Safari Park, in particular, was not financially viable for a long time and only recently turned that around? Based on the Metzler anecdote, it sounds there was needless to say a lot of downside to this approach, which is really unfortunate to hear.There is, of course, more problems in AZA zoos than simply the "big bad AZA and Mr. Ashe". The aforementioned trend of putting non-zoo and non-animal people in charge of animal collections. Then there's the simple, yet astonishing lack of interest from curatorial staff in working with most species.
I think you've hit on something major here by bringing up the internal promotion aspect, and I think it's much more significant than many would like to think. We have the luxury of being well-informed (and I try to be open and humble that most of you are far, far, far better-informed than me) but you can be fully qualified to join a zoological institution and not be. I am very close friends with someone who has studied biology, a very intelligent and wonderful person, but they are not necessarily informed on the taxonomy of species of monkey and antelope, or on the finer details of a pangolin. It's not hard to imagine someone who is interested in a career in the field who will need guidance from the TAG programs and when told a species is aging, inbred and non-viable - okay, we'll accept that answer and move on. Why construct a costly, purpose-built habitat for Indian Gaur if you're being told the species is already dying out and may need to be replaced in a decade? It makes more sense to pursue an active or emerging program, or something already popular that can fundraise more money.It's difficult to say how intertwined this lack of interest is with the AZA systematic promotion vs anti-promotion of certain species, though I expect their is a link. How could a hoofstock curator become interested in picking up Gaur or Bactrian Deer when all the information coming from the AZA/TAG is that the populations are small, aging, inbred, and non-viable; meanwhile, the populations of both (each held by 3 holders or less in North America) exceed that in European zoos with regular annual breedings and increasing population trends.
I agree that there is nuance, gray area and complications when it comes to working with private keepers, a lot of which is complicated by the expectations of the public and marketing.And then there's the resistance to working with private keepers. Being a zoo keeping an animal = good, but a person keeping an animal = bad, even though many keepers and curators are private keepers themselves. This issue has a huge amount of nuance, grey areas, and complications to it, but there seems to be a pretty blanket stance within the zoo leadership community that private keepers have no place in conservation breeding. I wonder where the TSA would be in their chelonian efforts if they did not rely on their large network of private turtle breeders and public zoos. I remember how badly the AZA reacted to Fort Worth sending the last female Anegada Ground Iguanas to Iguanaland. To swing back to the initial topic, the White-Lipped Deer program relied on cooperating with the large population of privately managed deer on Texas ranches, something that today is largely looked down upon.

There is a lot of harsh reality in all of this, and a lot of it needs to be accepted as such, but for me it added an uncomfortable texture where I felt guilty and a little ashamed viewing rarer species, and started worrying that holding them was equivalent to a vanity project without sustainability plans.
Why construct a costly, purpose-built habitat for Indian Gaur if you're being told the species is already dying out and may need to be replaced in a decade?
Sustainability affects this too, as you already know and mentioned in the thread. The expectation of Species Survival Plans and accredited programs is to keep track of origin, provenance and bloodlines, and some private keepers do not do this
There are species doing well in the private sector where there is no strong reason to exclude them from the AZA, and some phase-out species that have persisted.
The takin situation is such a mystery to me. Caprid and most exotic Asian hoofstock programs seem to be doing poorly, even some attractive and well-known species, but takin in spite of that, their own obscurity, and low genetic diversity, seem to have spread somewhat rapidly from when ZooChat still considered them a rarity, and seem to be the 'token' hoofed animal for new Asia developments. There must be some behind the scenes reason - perhaps easy to work with? - because they fly in the face of a lot of trends.This is the biggest issue the AZA is getting itself stuck on. Higher management is pushing to maintain genetic diversity as high as possible, even if it means ending up with generic populations. Binturongs and Ocelots are both now being paired across subspecies to preserve genetic diversity - yet I'm not aware of any known issues that were starting to arise. 63% of the American Flamingo population is recommended to only breed for exhibit needs while they try to create a known pedigree population - meanwhile the "pedigreed" flocks are barely reproducing at all. Most of them are in too small of a flock or something isn't working.
Meanwhile they're still pushing species like Takin which has a relatively low genetic diversity metric.
This is what really worries me -- exhibit standards for megafauna have climbed in the last few decades and some major zoos are still catching up to developments from this period. If these standards continue to climb, and I expect they will, we will continue to reduce our holding capacity to care for these animals. Fewer individuals needing more space may bode poorly for overall captive populations over time, and will force more non-ABC species into difficult positions. If a zoo determines giraffes need double the space, they will have to eliminate other species. Brookfield and Lincoln Park both phased out Andean spectacled bears to expand their polar bear exhibits, contributing to the crunch they are under; a lot of other historic bear lines underwent this, making them an easy example. This in no way meant to be a defense of poor exhibit design and bad welfare, but it is a reason I feel the lack of new facilities is a problem.This is inherently true - there are roughly 150 "traditional" zoo accredited facilities in the US depending on how you what you want to consider one. Space for large animals is somewhat limited, and when you have multiple contenders (say the half dozen bear species) it can start getting cramped. 150 zoos divided by 6 is only 25 slots each. Now some zoos have multiple species of bear and others none at all, so it's obviously a lot more complex than that. But the reality is space is an issue for larger species.
I do really appreciate this thought.There are currently 288 SSP programs, a decidedly small fraction of the total number of species held by AZA zoos. The reality is there are far more non-SSP species present than there are SSP species, and there's no need to feel guilty about rarer species. San Diego Zoo alone had well over double that 288 earlier this year and there's a lot of SSP species they don't hold.
I have a guess as to why but I'd be curious why you personally think Gaur have the upper hand?The slight irony being the AZA wanted to push Banteng instead - which as I understand it was no better off in terms of population numbers or genetics. A toss up ultimately, but I suspect Gaur may now have the upper hand.
Of these, I was only aware of Ostrich and had suspicions about spider monkeys and chinchilla. Interesting to hear about Tamandua and Kinkajou, both species I am fond of.And yet many common species in the AZA are sourced from private keepers - chinchilla, Ostrich, Red-eyed Treefrog, Eastern Blue-tongued Skink, and others are simply "readily and ethically available." For that matter Southern Tamandua and Kinkajou are still almost completely reliant on confiscations and donations, breeding is virtually nil. Last I was aware European Legless Lizards were still almost entirely imported, often from the wild. The SSP is bordering desperate on placing spider monkeys from all the confiscations at the southern border, breeding is unneeded.
This is something I've been wondering a lot about recently, especially since I read that bit about chimpanzee genetics and some of the comments in the "Zootierliste in America" thread. This is exactly where the AZA runs the risk of looking like they can't follow their own rules.Also worth noting there are plenty of SSP's where bloodlines are poorly known, yet they are retained on SSP status.
I knew Duke was a powerhouse and you had mentioned Rum Creek and DWA before, but it's new for me to hear about SeaWorld and St. Augustine's roles. It does interest me how champion facilities seem to prop up a lot of the programs at the end of the day, and part of me feels this is a positive for allowing these facilities to specialize, hone in their focus and enrich the AZA at large with their efforts, and gives them room sometimes to experiment a little with species' husbandry to perfect it, but as you point out, you also run a huge risk that if any of these champion facilities falter, it could have a domino effect.A lot of species are doing better in the private sector than they are in the AZA, particularly on the hoofstock, bird, and reptile fronts. There are several cases where breeding has seen far better success in the private sector.
One other comment though not mentioned in your post - we often tend to think of facilities propping up species as Gaur at Bronx or Koala at San Diego, small and not expected to do a whole lot. The reality is a quite a few of the SSP programs are bolstered by a single holder. If Rum Creek quit working with the AZA Pygmy Hippo would fall to a studbook and be pressed to hang on. Duke Lemur Center is critical to Coquerel's Sifaka. The SeaWorlds hold the significant majority of the King and Gentoo Penguins. St. Augustine remains the backbone of the all crocodilian TAG programs. DWA is a significant holder to multiple bird programs. A lot of more limited scope SSPs have a champion facility, and should that facility ever falter the species, the SSP could potentially fall apart.
The takin situation is such a mystery to me. Caprid and most exotic Asian hoofstock programs seem to be doing poorly, even some attractive and well-known species, but takin in spite of that, their own obscurity, and low genetic diversity, seem to have spread somewhat rapidly from when ZooChat still considered them a rarity, and seem to be the 'token' hoofed animal for new Asia developments. There must be some behind the scenes reason - perhaps easy to work with?
I wasn't aware of the American flamingo situation. It seems well-known and acknowledged at most facilities that larger flocks are helpful for breeding and this is why more and more zoos seem to be displaying multiple flamingo species at the same time in mixed flocks. It seems like it would be a no-brainer to centralize the pedigreed flock together for stimulation.
Brookfield and Lincoln Park both phased out Andean spectacled bears to expand their polar bear exhibits, contributing to the crunch they are under; a lot of other historic bear lines underwent this, making them an easy example.
I have a guess as to why but I'd be curious why you personally think Gaur have the upper hand?

but it's new for me to hear about SeaWorld and St. Augustine's roles.
I see what you mean better now, thank you for elaborating.Consolidation would benefit breeding, but also makes tracking and pairing birds a good bit harder. It's doable and facilities are managing - but when the population is more than 2000 birds strong with a number of wild born birds still present, I feel harping about inbreeding and genetics is a tad blown out of proportion. The chances of Denver and Tampa managing to breed their small pedigreed flocks are not high.
I see what you mean, especially in regards to otters. The NARO/ASCO combination is exceedingly popular in zoos, and it's hard to justify a third species. Toledo being forced to switch from spot-necked to NARO is one of the more awkward cases I've seen where the habitat was clearly intended for an exotic species. It's also unfortunate that neither spot-necked otters or Cape clawless otters were successful when African regions are ubiquitous and otters are very popular and attractive animals. I am hopeful for Giant otters to spread as they are very charismatic.This example is the nail on the head to the problem more so than space requirements going up. Grizzly Bear, American Black Bear, Bobcat, Cougar, Striped Skunk, and NARO are taking up a tremendous amount of space that could be used for more endangered carnivores. Rescued wildlife needs places to go, but it's coming at the heavy expense of filling space.
There absolutely was some losses with the need to increase spaces for species like bears and elephants, and it was a necessary move. However there is still lots of spaces, just occupied. It irks me we're breeding NARO and pretty much dropped everything else. There is at least a push to get Giant Otter established better.
Yeah, my speculation was that Bronx's commitment to the Gaur may eventually outstrip a patchwork dedication to Banteng by other facilities holding them in smaller numbers, but that was more of a guess. It looks like Banteng are only held in two traditional zoos and two of the breeding safari park-style locations. I had no clue that Banteng were as rare as they were actually; for some reason I thought they had a few holders more.Populations are roughly equivalent afaik, and Bronx is currently pretty committed to them. The Banteng population is more all over the place. Could go either way really.
Very cool. I was aware of their participation and "croc school" but hadn't really thought of it in the big picture. It's cool to think of them as a support system for zoos' crocodilian programs.St. Augustine is a major holder for all the crocodilian programs, and often the primary breeder. They participate in a lot of other SSP's as well, but are most notable for the crocs. They also have "croc school", a periodic training event where staff can get hands on experience with various aspects of crocodilian husbandry.
That's fascinating. SeaWorld is so often reduced these days to the cetacean collection it's easy to forget how much of a role they play in promoting other marine life.The SeaWorlds are a lot more involved than a lot of people realize. The subantarctic penguins are championed by them, and were responsible for getting most of those populations off the ground to begin with. They also do a lot of pinniped work, and maintain a good chunk of the Harbor Seal and California Sea Lion population between the three of them. Additionally Orlando in particular participate in a lot of AZA programs - I count 55 SSP and studbook species off their May USDA, so when you add herps and fish in gives them a pretty high count indeed.
