BIP National Loss Survey Comparison with NASS results

The National Agricultural Statistical Service (NASS) recently reported the results of its second honey bee colony loss survey. The Bee Informed Partnership (BIP) also recently published preliminary loss results covering the same period. Despite the differences in methodology and sample sizes, these two surveys yielded comparable results. Specifically, we estimate 33.23% losses based on the BIP survey, and we estimate 35.39% losses when we use BIP methods to calculate losses from the NASS survey (Table 1). This is reassuring as it suggests past BIP surveys are representative of national losses despite the non-random nature of the BIP respondent pool. Both of these surveys were created…

National Management Survey App

If you haven't heard by now, the Bee Informed Partnership has been hosting an annual management survey for many years. The survey is data intensive and collects detailed information about many different aspects of beekeeping. The survey has reached tens of thousands of beekeepers and has spanned the better half of the last decade. The survey has proved to be very successful and has generated a significant amount of data. Our team of researchers and technology professionals have spent many years analyzing this data to gain a clearer picture of honey bee health. Now, we want to make this data easily accessible to everyone by…

Interpreting and Understanding the Differences in Honey Bee Colony Loss Numbers From Different National Surveys.

Over the last year, and for the first time, the National Agricultural Statistical Service (NASS) conducted a survey to monitor colony losses. The Bee Informed Partnership (BIP), in collaboration with the Apiary Inspectors of America, has also recently published preliminary loss data covering the same time period. While the core purpose of these two surveys are the same, to track honey bee colony losses in the US, there are significant and important differences in survey design (questions asked), delivery, data presentation, and the methodology by which loss rates are calculated.  These differences mean that dissimilarities in loss rates reported by both surveys are expected. This…

Colony Loss Survey 2012 – 2013

A national survey of managed honey bee 2012-2013 annual colony losses in the USA: results from the Bee Informed Partnership Abstract: For the past six years in which overwintering mortality of honey bee colonies has been surveyed in the USA, estimates of colony loss have fluctuated around one-third of the national population. Here we report on the losses for the 2012-2013 seasons. We collected data from 6,482 US beekeepers (6,114 backyard, 233 sideline, and 135 commercial beekeepers) to document overwintering mortality rates of honey bee colonies for the USA. Responding beekeepers reported a total 30.6% (95% CI: 30.16-31.13%) loss of US colonies over the winter,…

Overwhelming Participation!

Late-breaking news for supporters of The Bee Informed Partnership – as of Sunday night, we have had over 4,000 participants in the Winter Loss Survey and almost 2,500 participants in the Beekeeper Management Survey!  This has exceeded our expectations and we hope to keep those surveys coming. We know that it is a tough decision whether to do your taxes first or take our surveys, but we aren’t asking for any money so perhaps that will sway your decision.  Please remember that the surveys are only open for 1 more week (closing on the same day that taxes are due – April 18th).  Thank you…
