While it is still early in the year for Vancouver Island marmots, our survey results so far have been positive. Overwinter survival for the marmots has been high, particularly among breeding aged females. This is exactly what we hope to find at this time of year. Later in the summer when pups start to emerge, we will be looking for signs of reproduction – that is to say active pups. We have feeders out at a number of colonies, which we believe may help the marmots reproduce more frequently. Our fingers are crossed that lots of those breeding-aged females have litters!
Many people have been asking about the weather. Vancouver Island has had a particular cold and wet spring, which followed a cold winter! However, it does not seem to have had any negative impact on the marmots. In fact, weather station data suggests that after a few mild alpine springs, this year’s alpine weather was closer to the historic norm.
While there is a lot of work ahead of us this year, this is good news for the start of the season! ... See MoreSee Less
Vancouver Island marmots are emerging from hibernation. This is wonderful news, but also a challenging time of year for the marmots. As they recover from 7 months of sleep, the marmots rely on the last of their stored energy reserves. Once they have reinvigorated their digestive system, they are able to find food, even in the snow covered mountains. Conditions in the alpine this year are fairly normal, despite the poor weather we have had at lower elevations.
We have put out feeders, targeted to help females improve their body condition rapidly. In turn, we hope they will breed more often than they would without help.
The BBC did a great segment on the challenge Vancouver Island marmots face this time of year:
