A Vancouver Island marmot is back in custody after hitting the trail, most likely looking for love.
Vancouver Island marmots are few and far between, so itѻýs no surprise that Camas, a young male originally released last year on Gemini Mountain, southwest of Nanaimo, didnѻýt hang around long when he discovered his prospects of finding a mate were slim to none.
At least thatѻýs a theory Adam Taylor, executive director of the Marmot Recovery Foundation, is working with to to explain why Camas went walkabout.
Camas was bred and raised in captivity at the Calgary Zoo as part of a recovery effort to raise the speciesѻý population, which the foundation estimates is about 200.
Marmots are tracked via radio signals emitted from tiny surgically implanted radio transmitters, which within the limitations of the technology, give a sense of the animalsѻý movements. Taylor said after being released on Gemini Mountain, Camas almost immediately headed over to nearby Green Mountain.
ѻýThere he encountered another marmot and he settled down, hibernated there, and we really thought this was going to be his home,ѻý Taylor said. ѻýAnd then, this spring, we were having a really hard time pinning him down ѻý we couldnѻýt figure out why and then, [July 5], we got a report from a fellow in Errington saying Iѻýve got this marmot in my backyard and sent us a couple of pictures and, sure enough, thereѻýs this Vancouver Island marmot in their backyard.ѻý
The foundation immediately sent a team which trapped the marmot in a neighbouring backyard, ending a journey that started about May 29, which was the last time researchers had caught a radio signal. Taylor said the foundation team wasnѻýt sure the marmot theyѻýd caught was Camas until they were able to check his ear tags.
ѻýSo, 30-plus kilometres from his home ѻý thatѻýs a straight-line distance ѻý heѻýd wandered through the mountains to end up in somebodyѻýs backyardѻýѻý Taylor said. ѻýAs to why he took to roaming, we donѻýt have a positive answer for you because I canѻýt ask him, but thereѻýs a pretty decent idea. Heѻýs a young male and young males often disperse from their natal colonies looking for mates.ѻý
Taylor said if the other marmot on Green Mountain was the same sex or if another adult male had moved into the area and started to mate with the only female there, that would leave Camas with pretty slim prospects for reproducing, so itѻýs not surprising that he would move on.
ѻýWhat is surprising is they donѻýt get lost more often,ѻý he said. ѻýYou have to imagine, Vancouver Island marmots are still phenomenally rare on the landscape. Weѻýve got a couple hundred of them, total, in the wild and theyѻýre stretched over this really vast landscape ѻý living in these small meadows on the tops of mountains ѻý Camas went the wrong way and just kept going.ѻý

Itѻýs also surprising, Taylor said, that the marmot descended to such a low elevation, although it has happened before. Bamfield Marine Sciences Centre students found one on a beach there, while another was found in a rock quarry near Nanaimo.
ѻýI know 30 kilometres doesnѻýt sound like much, but this terrain, these are pretty serious up-and-down mountains, so he covered a lot of ground really fastѻýѻý Taylor said. ѻýMarmots arenѻýt particularly well-adapted to surviving in the forest. Where they canѻýt see their predators, theyѻýre at a real disadvantage and we know that their survival rates are really low, so heѻýs certainly a survivor and managed it, but I donѻýt know how much longer he would have lasted.ѻý
Taylor said the foundation is incredibly grateful to the people who reported the marmotѻýs arrival in their yard. Camas is now at the Tony Barrett Mount Washington Recovery Centre where researchers will keep an eye on him for a while to make certain heѻýs healthy before he is re-released later this month.
