It is a tough subject to really put a gauge on, because the weather patterns do change over time and there's an ebb and flow there.
Part of what we're doing with bees in keeping them alive in Canada is that we're pushing them to the absolute limit in trying to keep them alive over the winter. If the weather patterns change just a little bit, it makes it harder. We have to make sure that all the boxes have been checked off—that the varroa mite count is low, that the other bee diseases are under control and that the bees are healthy going into winter.
If any of those boxes haven't been checked off, along with an extra couple of days of cold, a little bit of extreme cold, or longer winters or longer springs than normal, that hive doesn't make it. That's part of the problem. We need to make sure the bees are extremely healthy going into winter.
