I'm assuming I'm supposed to speak to this, and somebody else can join in if they wish.
Certainly, there are many factors affecting survival, and a huge one is weather as well.
In a year that we have particularly high losses, my observation has been that it can be related to the severity and length of winter, which can be very regionally dependent within Canada, of course. It is also, to some extent, the ability for some of our effective disease and mite controls to bring down this disease and mite levels to acceptable levels before winter. Inevitably, a colony which isn't well treated and isn't well fed going into winter will experience a high loss. There are certain environmental factors that can affect that, which again can be the inherent weather, and also some of the forage availability to bees in the fall if they're not well supplementally fed.
We will experience swings. What I would point to is that we now have nine years of very good data looking at winter loss, and there are swings. Overall, if we look at the level of loss, it's still on average fairly high compared to our long-term losses, which would be around 15% over winter. We're still a good 10% above that, but perhaps the trends indicate we're moving in the right direction, and we have to continue to do so.
