2012 Thru 2013 Over Winter Honey Bee Survival Survey Results



I'm collecting survey results from around the country to see how other beekeeper's over winter survival has gone. The survey is still under way and I'll continue to post results weekly as I get more in.
If you haven't taken the survey and you're a beekeeping in the USA, pls take 45 seconds to fill this survey out Quick Bee Survey
