Canada Post Strike Update: We will get your donations! We want to assure you that your mail will reach us, despite the current limited job action at Canada Post. As you may have heard, Canada Post has begun rotating strikes, including here on Vancouver Island. The job action may impact how long it takes your mail to reach us, and vice versa, but mail will still be delivered.
Alternatively, you can give to us online at marmots.org/how-you-can-help/donate-now/, or phone us at 250 390-0006 or 1-877-462-7668 - we do love to chat with you about your marmots!
Your gifts are reason we are able to continue the marmots’ recovery. Thank you all so much for supporting this special animal and our work to save it. ... See MoreSee Less
More research! The Marmot Recovery Foundation is collaborating with Dr Jamie Gorrell of Vancouver Island University to map the genetics and as much of the captive and wild population as we can get samples from. When complete, this research will help us make more informed choices about which marmots to pair in the captive breeding program and where to release marmots. When our recovery effort began, the marmot population was frightening small. At its lowest point, fewer than 30 remained in the wild. With that severe population bottleneck in mind, the captive breeding program’s first priority has been to conserve genetic diversity and minimize inbreeding. But to do that, we have had to make assumptions. For instance, we assume that marmots from distant colonies are not closely related. In the wild, we assume that the male marmot that hibernates with the mother and engages in parenting duties is the father of the pups.
Dr Gorrell’s work will enable us to have a much closer look at the genetics of the marmots, and test whether our assumptions have always been right. If there are areas of concern, for instance a colony where all the marmots are more closely related than we believed (we’re looking you Alan, we know you get around, but just how much getting around have you been up to?), we can take corrective action. For instance, we could release marmots to the site, or even translocate marmots, to give a fresh infusion of needed genes.
We are really excited about Dr Gorrell’s work, and his results will help us better understand the marmots needs.

The transition from life in a Zoo-setting to life in the wild is dramatic for our Vancouver Island Marmots. Despite the efforts that the Calgary Zoo, Toronto Zoo and ourselves make to ensure marmot enclosures resemble the wild, with free access to outdoor spaces, artificial burrows, and rocks and logs to climb and carry, there is no way to truly recreate the boundless spaces, cliffs, and meadows of the marmots’ natural habitat. So it’s amazing to see how quickly the marmots adapt to their home. Often we will see them eating wild vegetation within an hour of release (sometimes it is just minutes before they start sampling the local delicacies).
However, we also know that other elements of the transition are harder. Captive bred marmots tend to go exploring more often than their wild born counterparts, which too often puts them in harm’s way. They have a harder time with their first hibernation too, especially in Strathcona Park where conditions can be harsh. The good news is that if these marmots can make it for a couple years, their survival from then on is just as good as their wild-born relatives.
To improve the survival of captive-born marmots, we decided to try releasing some to the relatively safe colony at Mount Washington for one year. The Mount Washington colony has lots of marmots, is lower elevation with more green for a longer time, and perhaps most importantly, has people nearby that scare away predators. The following year, we re-capture these “stepping-stone” marmots and release them in far more remote colonies in Strathcona Provincial Park.
It seemed to be working, but analyzing the data to build a solid model of the difference this “stepping-stone” approach made was very difficult. Thankfully, the Calgary Zoo’s Centre for Conservation Research and U.S. Geological Service agreed to analyze our data. And indeed, this release methodology makes a substantial difference, and captive-bred marmots released using the stepping-stone approach have much better survival rates in Strathcona Park. When the first results came in two years ago we transitioned entirely to this approach for all marmots released to Strathcona, but it has taken longer to get to publication.
Now, you can read all about it in the journal Animal Conservation!
