There are regions from which honeybees have just disappeared. It's too bad because it's a glorious honey-producing area, but it's a terrible honeybee wintering area. That's more or less north of the Peace River. There are thousands and thousands of acres of canola and mixed farming in that area.
In June and July there are 20 hours of daylight. There used to be a bee industry there. The producers there produced terrific crops, but now that you have to overwinter them, it just doesn't work there. I would say the further north you go, the higher the attrition.
