Species no longer held/nearly gone from US zoos

I would take some of those numbers with a grain of salt. US entries only started getting added a month ago, and there are still many holdings left to enter as well as errors to fix. As an example, I suspect there are more than 5 US zoos with Eastern Grey Kangaroo...

Also worth noting that some species being in low numbers aren't necessarily a sign that they are "disappearing". Tasmanian Devils in the US have always been dependent on imports from Australia, so they've never been common and their numbers fluctuate based on when the most recent imports were. Also not sure either of the wombats are actually in decline; Common Wombats are not a breeding species here, and Hairy-nosed I think have had more or less the same number of zoos holding them for a while.
According to ZTL, the following marsupials are kept in up to 5 US zoos
The southern hairy-nosed wombat and eastern grey kangaroo are held at 5 US zoos.
Derby's woolly opossum, parma wallaby, swamp wallaby, yellow-footed rock wallaby and narrow-toed feather-tailed glider are held at 4 US zoos.
The Tasmanian devil is held at 3 US zoos.
The New Guinea ground cuscus, agile wallaby and common wombat are held at 2 US zoos.
The four-eyed opossum, bear cuscus and grey short-tailed opossum are held at 1 US zoo.
Feathertail gliders are not disappearing. Yes, there are only a few holders, but they've never been common and some of those zoos have very large colonies.

is there a reason why common wombats are non-breeding? is it just because there are two few of them here and no one since Houston in 2014 has tried importing any more?

My guess would be that the focus is on Southern Hairy-nosed Wombats; that species has been breeding here for a while (mainly at Brookfield) and multiple zoos have imported animals in recent years to try and grow the population.

Also worth noting that Houston's 2014 import was two females, not a potential breeding pair.
 
I feel like carnivorans have taken the biggest hit, but it’s important to remember that the majority of species being phased out as a whole are ones that weren’t common in the first place…
I don't think there would be any data to back up carnivorans taking the biggest hit. While yes, there have been some losses (e.g., margay), and some with an uncertain future (e.g., dhole, bush dog, striped hyena), there are still a lot of carnivorans with very large populations, much more so than either primates or ungulates. Furthermore, carnivorans is an area there have also been *gains*, especially thanks to Nashville Zoo.
 
Common wombat, bear custo cus, Tasmanian devil, hairy-nosed wombat, agile kangaroo, and some non-CW opossum species are good explain

I believe AZA lost the grizzled tree kangaroo, Goodfellow's tree kangaroo, tiger quoll, striped possum, and bare-tailed woolly opossum after 2010.

Also, Bear Cuscus is not "disappearing", they were never here in numbers anyways. We only get Tasmanian Devils when they're post-breeding age and have 3-4 years left. Again, we can't really claim losing something we were never managing a population of in the first place. Many of the opossums are short-lived to begin with and are continually being imported to refill the gaps, besides not being very common in larger zoos in the first place.

Who had Grizzled that recent? Goodfellow's Tree Kangaroo was a deliberate phase-out following a consortium decision of NA focusing on Matschie's and Europe focusing on Goodfellow's. Tiger Quoll and Striped Possum are both not particularly long-lived and without careful effort in maintaining the population will readily die out anyways.

San Antonio Zoo was the one with the Grizzly tree kangaroo, and Europe isn't the only region that works with Goodfellow’s tree kangaroo. Oceania and Asia also do their job on Goodfellow’s tree kangaroo

As I already stated, we don't hold Goodfellow's because of the consortium decision on how to dedicate enough space to both Goodfellow's and Matschie's. Oceania maintains multiple species, but they also have fewer options for filling the slot of medium-sized arboreal mammals.
