Christ, do we even have any bees left at this point?
Christ, do we even have any bees left at this point?
Of course, 50-60% sounds alarmingly high, but I don't know enough to be sure.
Actually, I just followed the link in the article (good job detailing their sources!) and it looks like 40% is pretty typical, but with large error bars. 62% is definitely high, but not as earth shattering as it first appears.
The other issue is crop pollination, which AFAIK has heavy reliance on commercial bees.
That said, most beekeepers expect to lose 30-50% of their hives every year. But most honeybee hives can be split into two hives every year. So if you can double (or even potentially triple, quadruple) each hive every year, a loss of 50% isn't catastrophic.
That is, you almost certainly need to know a lot more facts about bees before knowing the die off rate is useful.
The Langstroth hive was invented in the 1850s, and the first migratory commercial hives started in the US 50 years later.
In the 1940s we saw a steady decline in hives, but the hives really started seeing massive die offs in the 2000s.
So no, the timelines are not really due to shipping commercial hives. There's other, stronger factors at play.
