I wouldn't count them out just yet.
Nobody is counting them out yet, but there is genuine cause for concern. One good year stands out against the backdrop, it's not just American bee colonies that are being hit by an increasing trend in mortality. The apiculturalists, and epidemiologists have identified a number of factors involved in the decline. A parasitic mite
Varroa destructor (now resistant against the two control products Fluvalinate resistance in some provinces, and coumaphos in most province)
, Israeli Acute Paralysis Virus, mono-cropping, and a number of other stressors.
But the mortality seems to go in jumps. There will be years where winter mortality is near normal (5-15%), and then there will be large events like the winters of 2007-09, where mortality rises to 36%. Of note, this tracked the same losses south of the border.
As a comparison, this year the Fraser River Sockeye had a huge return this year, the estimates are coming in that it is the largest year class in close to 100 years. That doesn't mean that they are rebounding, in fact for one of the spawning populations in the Fraser River there is a huge cycle, and we're at the peak this year. It's likely that the cold temperatures during their smolt run that year helped immensely.
Just as a single year in a climate record means nothing about the overall system, neither do single year mortality rates in bee hives, or single year spawn runs in salmon.
