2020-2021 Annual Colony Loss Report with Bee Informed Partnership (S4, E3)

Beekeeping Today Podcast

Dr. Geoffrey Williams and Dr. Nathalie Steinhauer join us in this episode to discuss the just released survey of colony losses between April 1, 2020 and April 1, 2021 conducted by the Bee Informed Partnership, BIP. The numbers are not getting better after 15 years. In fact, beekeepers across the United States lost 45.5% of their managed honey bee colonies last year.

The survey asks beekeeping operations of all sizes to track the survival or turnover rates of their honey bee colonies. This year, 3,347 beekeepers managing 192,384 colonies across the country responded to the survey, representing about 7% of the nation’s estimated 2.71 million managed colonies. This effort helps to keep a finger on the pulse of what is going on with beekeepers to identify why high losses are persisting.

These losses mark the second highest loss rate the survey has recorded since it began in 2006 (6.1 percentage points higher than the average annual loss rate of 39.4%). The survey results highlight the continuing high rates of honey bee colony turnover. The high loss rate was driven by both elevated summer and winter losses this year, with no clear progression toward improvement for beekeepers and their colonies. BIP hopes to use the survey results to better understand how colony losses are experienced by beekeepers, and what can be done to reduce losses in future seasons.

This past year, winter losses were reported at 32.2%, which is 9.6 percentage points higher than last year and 3.9 points higher than the survey average. Summer losses were some of the highest ever reported again this year at 31.1%, which is 0.9 percentage points lower than last year, but 8.6 points higher than the survey average.

Join us as we discuss the preliminary findings of this latest BIP survey!
