Survey: Bee losses slowed in 2016-2017

An annual report from the Bee Informed Partnership (BIP) and Apiary Inspectors of America (AIA) showed fewer losses of bee colonies in 2016-2017 than the previous year, according to a press release from Bayer CropScience.

An estimated 21.1 percent of colonies managed were lost over the 2016-2017 winter, an improvement of 5.8 percentage points compared to the previous winter and falling well below the 10-year average total winter loss rate of 28.4 percent. It's the lowest winter loss rate since these surveys began.

"This is terrific news for everyone who cares about bee health," said Dick Rogers, principal scientist and beekeeper for the Bayer Bee Care Program in North America. "As I reported last month, we are not out of the woods, but there is a reason for optimism, given the industry's commitment to protect these vital pollinators."

BIP and AIA surveyed more than 4,900 beekeepers.

Beekeepers not only lose colonies in winter (October - March) but also throughout summer (April - September). The 2016 summer colony loss rate was 18.1 percent. When all the survey results were combined, beekeepers lost 33.2 percent of their colonies between April 2016 and March 2017, the second lowest rate of annual colony loss recorded over the last seven years.
