The Bee Informed Partnership has released its annual survey of the national health of bees in America, and yet again the number of colonies is shrinking.
Bee hive losses have increased, according to the survey, which said U.S. beekeepers lost 44 percent of their hives from April 2015 to April 2016.
Last year’s losses amounted to 40.6 percent. And losses in summer 2015 increased to 28.1 percent of hives, the same rate of loss for winter 2015.
