how bees are doing in US

Bret Adee, a third-generation beekeeper who owns one of the largest beekeeping companies in the U.S., lost half of his hives — about 50,000 — over the winter.  He pops the lid on one of the hives to show off the colony inside.

Greta Mart/KCBXFor decades Adee says if he lost 5 percent he really got nervous. Now a 40 percent loss every few years is more common, he says. But this many lost hives across the country is concerning.

Fig 1. Total winter colony loss rate in the United States across years of the Bee Informed Partnership’s National Honey Bee Colony Loss Survey (yellow bars; 1 October – 1 April)1. Total annual loss estimates (orange bars) include total winter and summer (1 April – 1 October) losses; the latter has been estimated since 2010-2011 only. The acceptable winter loss rate (grey bars) is the average percentage of acceptable winter colony loss declared by the survey participants in each year of the survey.
