Vancouver Island marmots can live for more than ten years, but they grow relatively slowly. This means that it can be fairly easy to recognize marmot pups and yearlings when you see them, because they are noticeably smaller than their older colony members. Their fur is also much more uniform in colour than the patchwork coat worn by adults! Most yearlings are a beautiful, warm cinnamon colour, like the yearling in this post’s photo. Field crew have been visiting marmot colonies and counting yearlings to determine how many of last year’s pups survived to celebrate their first birthday. And the good news? The yearlings that have been observed in the field have been in excellent physical condition, thanks to an early spring, rapid snow melt, and abundant vegetation.
On a sunny day last week, CTV News pulled on their hiking boots and came out in the field with us for a day of counting marmots. We asked the marmots to put on a special show for them, and wow, did they ever come through! We saw marmots basking in the sun, marmots foraging on vegetation, and marmots ripping up sedges and carrying them back to their burrow for bedding. Not bad for a day trip! The Vancouver Island Marmot Recovery Project is working hard to recover this species to a healthy population size and distribution. And although we still have lots to do to protect the species for the long haul, we are so excited about all that we have achieved so far! Have you watched the CTV story?
Last week we received this season’s first report of a dispersing marmot. Two forestry workers photographed a marmot on a gravel road in the Nanaimo Lakes region. “Dispersal” is a natural process that happens when a marmot leaves the colony that they were born at, and travels through the landscape to join another colony and start a family. For Vancouver Island marmots, this usually happens at or after age two, when marmots are fully grown and independent but have not yet bred at a site.
From the photos, we could tell that this marmot was known to us because it had two shiny, metal ear tags with numbers on them. We couldn’t quite read the numbers from the photos, but that gave us a great start at figuring out who it might be. We knew that if the marmot had ear tags, it likely also had a working radiotelemetry transmitter. Transmitters send out pulses, and by using a special antenna and receiver and walking in the direction with the loudest pulse, we can track a marmot to a specific location – kind of like a game of “hot or cold”, but with beeps!
We solved the mystery when we confirmed that it was a 2yo wild-born male named Precip. By the time we found him, he had finished his journey and was hiding in a nice, meadowy slide on another marmot mountain. He had traveled 10km from his natal (birth) colony to where he was photographed, and another 5km after that! We wish him all the best at his new colony.
Vancouver Island is a BIG place, so we appreciate your help monitoring this rare and fascinating species. If you see a marmot near a town or road, or if you find a deceased marmot, please let us know!

It may have been snowing sideways, but ShawTV’s Kelly Robinson and Derek Johnstone were all smiles as they trekked along with us on our first field day in early May. It was an exciting day for everyone – we saw happy marmots, checked burrows, and confirmed overwinter survival for several individuals. We also had a surprise when we discovered that a notorious wandering female who had left the hill last summer had returned to hibernate with a friend.
