I know it’s been a while since this has been discussed, but how do you all think the Minnesota Zoo should utilize the former musk ox exhibit, since AFAIK, it’s still just sitting empty? I know another species of hoofstock would definitely be the most likely replacement, but I’m not sure which one would be the best fit, so I’d like to see what the rest of you think.
There are a few seemingly plausible options that would maintain the theme of only exhibiting cold-tolerant species outdoors.
Over the past several years, one of the recurring ideas in the different plans has been to erect an exhibit for elk on some of their currently undeveloped land. With the Asian wild horses that had been amassed for the later canceled release in Russia finally gone, I wouldn’t be surprised if elk are acquired for this enclosure instead of one that has yet to be built. That is, if they really are seen as a priority addition to the zoo. Manitoban elk are native to Minnesota, so they are probably the most likely candidate of the different subspecies, but Roosevelt elk and rocky mountain elk are also options. Minnesota's regulations in place to control Chronic Wasting Disease would not preclude the zoo from acquiring elk or other cervids from another state, either.
Transcaspian urial, Bukharan markhor, and mountain goats all might be considered, but none seem likely. When the urial were still in the Tropics Trail, there were plans for an outdoor enclosure for the species, and the muskox enclosure could theoretically serve the same purpose. Now that urial have been gone for a few years and also now that red pandas, whom urial were supposed to share that proposed enclosure with, are being added as a replacement for the dholes (much to my disappointment), the urial most likely aren't a priority.
In terms of other caprines, the ibex, tur, tahr, mouflon, and aoudad species are only barely worth mention, as are the takin subspecies only held by San Diego and private hands. I suppose rocky mountain bighorn and Dall sheep are possible, but still very unlikely.
Bactrian deer and Père David's deer would both be able to handle the Midwestern climate. The latter would be easier to source as they are in more zoos and are recommended by the Taxonomic Advisory Group, or at least the population is recognized.
Also, the enclosure might continue to serve as an auxiliary space for the hoofstock species that are already held. This is honestly probably the most likely. Well, that or orphaned white-tailed deer.
