They have wonderful conservation story as well. During the 90s they were one of the rarest mammals on the planet with a population in the mid 30s. Thanks to a plan to make a genetic ark by capturing and captive breeding those individuals the wild population is now in the low hundreds. Still precarious, but hopeful.
As said before my "problem" with them isnt that they are a bad pick, but one that doesnt make a lot of sense logistically.
Just compare popular choices for an island vs mountains.
Mountains we got many different caprines with not more then 2 of them being expected in one pack, spectacle bear, pallas cat, himalayan monal/golden pheasent would be a smart choice and then there also stuff like the yellow footed rock wallaby, an alpine monkey like the geladal, the domestic yak and the marmot. Afterwards thats kind of it regarding popular suggestions that are mainly mountain animals
shoutout to all taiga and tundra animals getting lumped in with mountains cause people are getting desperate.
Meanwhile islands? Just the ones rather commonly discussed are the fossa, kiwi, tasmanian devil, treekangaroo, blue penguins, rockhopper penguins, green seaturtle, victoria crowned pidgeon, scottish highland cattle, shetland pony, racoon dog, japanese serow, lowland anoa, sulawesi crested macaque, northern luzon giant cloud rat, nene goose, pig nosed turtle, a second lemure, sumatran rhino and then theres still all the whacky lesser discussed great pics like the kunekune pig, parsons chameleon, kagu, solomon island skink, scottish wildcat, white cheeked pintail and the list can go on and on and on.
By the nature of islands allways having very specific different and unique animals depending on whatever got trapped/stranded there allmost any island with a significant time of isolation has very unique species. Meanwhile most mountain ranges can be described in high priority missing animals as goat and i doubt that we will get a 3+ goat pack.
From another standpoint, the alpine marmot would also bring in some europe representation and would retroactivly enhance the ibex as another animal iconic to the alps.
Afterall we just hopped off a year that featured twice as many north american small mammals then europe got overall. North America really is not in need of more small mammals, meanwhile europe could still use any animal it can get to grow to a decently sized roster.
Lastly visually, both species are basically just a giant prariedog, one brown and one slightly larger and grey yellowish.
Just from a visual perspective, there isnt really any reason for frontier to pick one over the other.
So yeah while they are a neat animal i just dont see them once you step back and look at the meta game of how the animals actually would most likly be added.
A mountain pack only has a rather small group of centenders with the marmot as an easy choice to throw europe another bone and represent the alps, while the vancover island marmot faces a much more fierce competetion.
If theres a pack filled with the kiwi, tassie devil, treekangaroo, fossa, nene, sulawesi crested macaque, shetland pony, who do you drop for just a brown marmot when a grey one would easily be among the best contenders for even a scenery mountain pack?
Ofcourse everyone can want what they want and if we get it id be happy for you, but i just dont see it happening.
