The 2006 date cited for CCD isn't the government acknowledging CCD. It's the first published reports of CCD in commercial colonies. It's not a giant conspiracy.
It's also worth knowing that overwintering losses stabilized after 2006, and commercial populations hit record numbers afterwards.
Clearly, there are bee stressors other than "colony collapse disorder". But beepocolypse advocates use the term "CCD" as a cudgel in any discussion about stressors or population losses. No, can't do that.
I don't need perfect data. Any data will do.
