(Spo)oktober Blog: Don’t be afraid of State Specific Colony Losses!

Happy Fall y’all!

In normal life, “Fall” means Halloween (and dressing up as fatbody-sucking Varroa mite) and Thanksgiving (we certainly are grateful to be part of the beekeeper community).

In beekeeping life, “Fall” means that nectar flows come to an end, queens lay fewer eggs, winter bees are being reared and we have to (still) deal with Varroa mites. All this is happening for a reason: To get the bees ready for and successfully bring them through winter. (Hard to believe here in Alabama where it is still blazing hot!)

You may remember that we reported the highest honey bee colony winter losses since the beginning of the survey in 2006 (in case you don’t, you can read the abstract here)! Beekeepers across the nation lost 38% of their colonies over winter.

In some states, one would define this season as “ice-cold, snowy, and long”; in others, it’s merely “one month of cooler temperatures”. As variable as climatic conditions are, so are beekeeping practices among the 50 U.S. states. We do acknowledge this by grouping our data spatially and presenting them according to state, federal district, and territory.

Like in previous years, we are providing data for Annual, Summer and Winter colony losses. As usual, we are presenting both Total and Average Loss for each region and season. A little refresher on what the difference is between our Loss calculations:

Total Loss = every colony is treated the same or “every colony gets a vote”. Thus, Total Loss is more representative of commercial beekeepers who are managing most honey bee colonies in the country as the losses are weighted toward those who manage more colonies.

Average Loss = every beekeeper is treated the same no matter how many colonies are managed by this individual. In other words, each operation, no matter how small or large, “gets only 1 vote”. We use operational loss then to calculate average loss. Therefore, Average Loss is more representative of backyard beekeepers since they make up the majority of the U.S. beekeeping community (numerically speaking).

Here, we included summary tables of our data as well as a map showing Total Annual Losses specific to each state (see below Figure 1; tables 1, 2 and 3).
To view even more region-specific data (e.g. Winter and Summer losses), head over to BIP’s Interactive Loss Map. In addition to nicely colored maps from various years, you can also compare the number of respondents. That being said: The more responses we receive, the more representative our data is. So: Spread the word and encourage your beekeeper friends to participate in the survey next Spring!

Some of you may sit there, eyes closed, fingers hovering over the mouse, dreading that their state had among the highest colony losses this year. Well, here we go!

Colony Loss 2019

Figure 1: Annual Total Colony Loss by state and federal district between 1 April 2018 and 1 April 2019.

Quick side note which will help to read the tables: N represents the number of beekeepers that responded from each state/district/territory. If a state had less than 5 participating beekeepers, we note that with a “<5” in the tables below and do not share the losses for privacy reasons. If you are in a state with fewer than 5 participating beekeepers, start talking among your fellow organizations and see if you can set that as a goal next year! We would love to have enough participants next year to have a full map.

Latest Loss Survey Results 2018-19

Dear BIP Survey participants,


You might have been wondering when the preliminary results of the 2018/9 Bee Informed Partnership Colony Loss and Management Survey will be posted.

Well, today is the day. Thanks for your patience!

The “traditional” abstract is now posted on the BIP webpage here, while the Press Release issued by the University of Maryland can be read here.

We want to thank all of you – whether you are a long-term respondent or a new-Bee to the survey – for participating this year. The information you provided is critical to building a long-term data set that we can now use to develop regionally-specific management recommendations.

Please keep your eyes on our national colony loss map and our interactive management portal. In the coming weeks we will be publishing our 2018/19 state-specific results.

Please take care!




The Bee Informed Partnership


Colony Loss Survey, Closing Soon!

The end is near; now hear how we got here!

April is about to end, and with that the Bee Informed National Colony Loss and Management survey will be hibernating (or summering) for another year. If you haven’t participated yet, we kindly ask you to do so here before the survey closes. This is our final advertising push, in the hopes that we can get another bump in participation! We are trying to beat last year’s number of submissions!

It has been an exciting month for the Bee Informed Partnership!

Participation rates of the Survey increased, reached a plateau, then rose again after a bit of PR.… It was like the weather this Spring.

Speaking of spring: This must have been an exciting month for you too since most of you have probably had more than a little peek inside your hives.
Did your bees survive the winter?
For more than a decade, BIP has asked this very question.
A little trivia about the early years of the Survey: Its pre-cursor was conducted collaboratively with the Apiary Inspectors of America in the spring of 2007 via phone. Yes, you read correctly; staff called individual beekeepers to ask about their winter colony losses and diligently recorded their answers.

It was not until 2010 that an online survey was created to annually conduct a loss survey to obtain baseline information of colony mortality. And for the first time, in 2011, BIP lead the effort to begin collecting loss AND management data.

Today the survey is so much more!

Knowing that colonies don’t just die in the winter, we now also calculate summer and annual losses. The survey officially consists of three parts: 1. Colony Losses, 2. Beekeeper Management, and 3. Socio-Economics.

Over the past 13 years, the survey has received more than 50,000 responses! The majority of these come from Backyard beekeepers but we always try to increase the number of sideline and commercial beekeepers with the hope of gathering a representative surveillance of all types of operations. This doesn’t mean that 50,000 unique beekeepers answered the survey; some participants re-visit the survey every year (thank you for your loyalty!!!), whereas others come and go. Although we do not know the identity of our participants, we do know that beekeepers from every state took the survey at some point in the history of the survey.

Although the survey is open for the entire month of April, preparations for it start many months prior.

Some of us begin the year with new resolutions. For BIP, January marks first preparations for the upcoming survey: we update the design, and include comments from previous participants (as much as we can). We then revise the first draft, test the online survey, revise the 2nd draft, re-test the online survey, and so on. It’s definitely a work in progress!

Apart from that, we eagerly write advertisements for the Survey that will run in major beekeeping journals, as well as on our website and Facebook page. If you would like to receive personal reminders in the future, including the link to the online survey as soon as it opens, please sing up here.

On April 1st, we start crossing our fingers. The online portal opens and by now, we have sent out about a 1,000 paper copies of the survey to participants of other surveillance programs such as the Sentinel Apiary Program or BIP’s Technical Transfer teams. From here, the survey is in your hands, beekeepers of America. Well, not exclusively. Throughout April, our E-mail support team is on alert to answer your questions and help you out with any questions that you may have.

May 1st is a sprint. As soon as the survey closes (April 30th), we run the numbers to use in our press release, which is shared with the media and our many stakeholders. Anyone can read our previous press releases too. Be aware that the listed numbers are not definitive. Our mailbox might receive some more paper surveys throughout May, which someone has to add to the database. Anybody who took the survey knows, this can take a while. But by the end of June, we analyze the data one last time and produce an updated state-specific map of colony mortality.

From there, the fun starts for our graduate students. They will spend several months slicing apart the data, analyzing, writing, and editing to prepare a peer-reviewed publication for one of the honey bee research journals as well as presentation material so that we can communicate results to beekeepers across the country.

Ultimately, the Survey allows us to study how beekeeper management and socio-economic factors possibly influence colony mortality. Beekeepers take note. Researchers take note. Policy makers take note, of the Survey. This is your chance to highlight the state of the industry!

Long story short: The Survey is a complex affair that wouldn’t happen without the dedication of many individuals, all of whom we greatly appreciate. And of course, it wouldn’t happen without you!

Waxing Poetic – A reminder of the BIP survey

Bee Informed Partnership’s Easter Basket

By Selina Bruckner, Auburn University

Dear beekeepers of America,

Easter Sunday is so close; but before celebrating we would propose,
For you to read this piece of poetry; which is much more than pure pleasantry.

April is almost coming to an end; most of which our bees have spent
Foraging on blooming flowers; while you invested all your powers
In adding boxes and catching swarms; because now that the weather warms
Bees get busy and buzz around; making their beekeepers really proud.

The question is: Have those bees, survived last winters’ freeze?
Or did you lose a colony? What an awful tragedy!
Did you check all of your hives; for the dangerous Varroa mite thrives?
Every year, BIP likes to ask; these questions to fulfill their task:
Quantify bee losses in the States; identify treatments and their rates,
Look at managements in each season; and ask: May this be a potential reason
Why honey bees will die? You can help to answer this huge “WHY”?!
So, before April ends for real; we kindly ask you to reveal
Your apiary notes from last year, and add them to the survey HERE.
The survey closes on April’s last; so go online, take the survey fast!
We appreciate your time and wish to say; Bee Informed and enjoy your day.

Hear Ye, Hear Ye!

Greetings Beekeeper!

The 13th annual Bee Informed Partnership National Colony Loss & Management Survey is LIVE!

In fact, it’s been live for 11 days already!

If you have submitted your answers – thank you, thank you, thank you. You are one of over 2,000 beekeepers that have done so!

If you have not, we are patiently waiting for you 😉 Remember, you only have until April 30th to participate.

The current number of survey respondents is tracking previous years. But like previous ones, we are reaching a little plateau in respondents now that we are over one week in.

That’s the signal that we need to reach out to you, America’s beekeepers!

We want to beat last year’s 5,000 responses! We also need you to be Town Criers – please pass on this message to fellow beekeepers! You don’t have to include the sketch 😉

To participate, please click HERE

To see a preview, please go HERE

Your contribution is impactful!

For example, it’s helping the Bee Informed Partnership to build annual state loss MAPS that are crucial to understanding how beekeeper management practices influence honey bee health.

So far we have built a WEB PORTAL that allows you to investigate how management practices are correlated to colony mortality.

But that’s only the start.

Thanks again for your support of our efforts! We truly believe this is a team effort by everyone.



SURVEY FAQs – Tips and Tricks to answering the Bee Informed Partnership’s National Colony Loss and Management Survey

Not even a week has passed since this year’s Colony Loss and Management survey went LIVE! As of this morning (4/5/2019), more than 1,200 beekeepers have already entered their information.

WOW! Thank you for your time and continued support!

So far your response rate is tracking previous years, but of course, we want to beat last year’s numbers! So please, spread word about our survey far and wide so that we can go above and beyond 6,000 responses!

Thankfully you are extremely keen on helping us to better understand your bees; why else would beekeepers submit to us many excellent questions during the survey period?

That is just one reason why the BIP mailbox is buzzing in April; our team is busy as bees responding to those questions.

We appreciate your interest and helping us to think about how to improve the survey!

The questions you pose are helpful to both the first time respondents, as well as to our loyal participants who trawl through their beekeeping records every year to provide us with their information.

We have compiled a list of frequently asked questions that may prove helpful to you when you are filling out the survey.

If you want to see additional questions in next year’s FAQ blog, or experience problems with the survey (we hope not though), please contact us via support@beeinformed.org.

We are listening to you!

May your bees start this season in strong, healthy colonies.

Your Bee Informed Survey Team


Q: Why should I bother?  What difference will it make?
A: A survey is only as good as its response rate. The more respondents, the more representative our results are. Thanks to your answers, we realize two objectives:

One, we estimate the level of colony loss experienced in the US. We have done this every year since 2007. This is an important legacy. We wished we had started it 20 years ago. Comparing the present to the past allows us to see how the situation progresses (or fails to progress).

Two, we can analyze correlations between management practices and colony loss. The same way human epidemiologists study our best and worst habits, and how it can impact our health. Correlative data has its limits, but it is a great way to identify hypotheses that can then be tested experimentally (which we also do in our lab and in the field).

We live in a stressful world. We know bees are also facing many threats, and sometimes those threats are outside of a beekeeper’s hands. We are not ignoring them and we actually hope the data gathered at county level will help us develop models to inform us about those other environmental variables.

Q: I already took a survey 2 months ago. Is this survey different?
A: The Bee Informed Partnership Loss and Management Survey is an annual survey which opens every year between April 1st and April 30th. We know there are more and more groups starting questionnaire-type surveys: we all want to know how the bees are doing! Our survey has been around for the past 13 years and we owe it to the dedicated beekeepers supporting us every year.

Also, the Bee Informed Partnership is a very active organization with several programs running in parallel, such as the Sentinel Apiary program. We also help to manage the APHIS National Honey Bee Survey. Both programs each have a short questionnaire that we ask beekeepers to fill out after they sample their colonies. This survey is different, as are the data gathered, target audience, reports and analyses.

Q: The link required a login. I could not access the survey.
A: The survey should open without any login needed, but several people seemed to face the same issue when following the link provided in personalized emails. According to our IT staff, this might be resulting from some various ad block settings. In any case, if you encounter a problem trying to access the survey, please close your browser and re-try the original link on the main page of our website, or copy the URL below directly into your browser. We apologize for the inconvenience.

Q: I stepped away from my computer and the survey timed out. Can I take it again?
A: Sure, it gets easier with every time you take it! Just kidding.
For real: Yes, you can take it again. We are filtering the survey to eliminate duplicates so we will only consider your most complete set of answers. If that happened near the end of the survey, please contact us, we might be able to help you.

Q: You are partial to the data and do not take all respondents into account.
A: All data points are super important. You are right though, we do exclude some survey responses, mainly because the numbers don’t add up.
BUT, we have a very strict protocol before invalidating answers (which we explain in the peer-reviewed publications every year). If more than 100% loss or less than 0% loss results from provided colony numbers, we have to assume that something went wrong during the data entry and consider that response invalid. We surely try to include as many surveys as possible. Nathalie and Selina will be hand sifting through the answers while validating data entries. They’ll also have a huge coffee pot next to them for extra power.

Q: I have not been able to assess the survivorship of my colonies yet as we are way up North.
A: We acknowledge this is a recurring limitation to surveying in April. Please give us your best estimate as to the number of colonies alive on April 1st. Any colony death that occurred after would theoretically be captured in next year’s survey. The survey will be open until April 30th so even if you cannot assess your colonies until later in April, that is fine and we would be grateful for the data.

Q: I think you are not covering all management issues in your survey / I think your survey is too long.
A: Please share your thoughts with us! There is a specific comments box and we are more than happy to get your input. Based on the participants’ recommendations, we try to improve the survey every year. We do not want to keep you on the computer for hours. Therefore, we are trying to reach an optimum between getting enough details and making the survey too fatiguing. Most questions also have open entries that should allow beekeepers to cover aspects they feel are missing from the main proposed answers. Nathalie, a postdoc in Dennis vanEngelsdorp’s lab (UMD), and Selina, a PhD student in Geoffrey Williams’ lab (Auburn) will look at every single survey, and be grateful to read some nice messages. It makes our days much better!

Q: This survey is more complicated than my tax declaration!
It is that time of year, isn’t it? The survey aims at estimating the rate of colony loss experienced by our respondents, and documenting the type of practices beekeeper use in their operation last year. It seems like easy questions, but you all know this: “Ask 5 beekeepers a question and you get 15 answers”. The survey aims at making the data very consistent for all beekeepers by removing interpretations. If you want to know what questions we ask in advance, don’t hesitate to look at the preview (it’s 500 times easier to read through too).

Q: What does the BIP team get out of this?
A: Well, thank you for asking. First of all, you are supporting the students working on this survey. Nathalie is going to publish an extensive 10-year overview of your answers and Selina will include the data in her thesis to graduate with a good knowledge of beekeepers needs. Based on your answers, we can also point out important topics to researchers so that they don’t run out of projects.

And depending on your interests there are some things YOU get out of participating (apart from proudly representing beekeepers in our country):

I’m mostly interested in…

  • Helping!
    • Thank you. Without you we couldn’t do any of this!
  • Bees.
    • If you are a beekeeper, you have been stung for life. The honey bees are a special kind of bees, but they’re not the only bees (or even the only pollinators) out there which are in trouble. We are all trying to do our part in understanding and helping out our pollinators. This survey is part of this effort. It’s probably not the only thing you can do, but it’s probably one of the best things you can do in less than 2 hours.
  • My bees.
    • Beekeepers love to experiment with their own bees to test what works and what doesn’t. With this survey, it is as if you experimented with everyone’s bees. Go to our Data Explorer page to compare treatments and practices. Also look through our other programs to see how we can help you the rest of the year.
  • Learning.
    • You’re our kind of people! Take advantage of our reports to tease out the information that interests you. We will publish our Best Management Practices soon. Also don’t hesitate to print a copy of the survey preview and use it to take notes all through the year.
  • Ranting.
    • Go ahead. We all need to do it from time to time. You’ll feel better. Just remember we’re all on the same team and when we work together, we can accomplish great things.
  • Money.
    • Our Data Explorer might interest you: you can look up and pick the practices and products associated with the best results. It is correlative data, not cause and effect, but at least it would allow you to rethink using products that are seemingly not showing any effect.
  • Science.
    • Bees are sentinels of our precious environment. Your data is contributing to the better understanding of the health of the bees. The question of honey bee health is complex and integrates many factors, some of which are not in the hand of beekeepers. By focusing on management practices, we are choosing to determine what beekeepers can do, given our current circumstances.

NOW LIVE! The 2018-2019 Colony Loss and Management Survey!

Good morning America!

It’s beautiful outside! The birds are chirping and the bees are flying! You may even notice a few flowers outside too!

Here in the South, our many azaleas are in full bloom! This means Spring is upon us!

The sun rising over the campus of Auburn University

And of course, Spring means one thing: it’s time to take the Bee Informed Partnership’s annual Colony Loss and Management Survey!

It’s easy! One click and you are in, ready to take the survey and to serve our nation’s beekeeping industry:


The information that you provide will be invaluable to our understanding of honey bee health around the country.

As background, the BIP’s National Loss Survey was launched for the first time in 2006, and thanks to the many thousands of beekeepers who have participated since then, we have been able to document and better understand long-term honey bee colony loss trends. Check out the interactive state loss map as evidence!

In 2010, BIP’s National Management Survey was added to help us understand how management practices are potentially linked to colony survivorship. Thanks to your answers, we have been able to develop a dynamic management data tool.

Feel free to play around with the interface. Want to know how colony losses compared between beekeepers that DID or DID NOT use a varroa treatment? Or what about the average age of comb in American hives? It’s all in there!

The Bee Informed Partnership’s dynamic management, data explorer tool

If you would like to prepare yourself for our questions, or want to take some notes while you’re looking at your colonies, download the survey or have a look at the 2018 – 2019 National Colony Loss and Management Survey Preview.

This preview should serve as an aid to the questions that are asked on the survey.  Please, do not mail this preview version back to us.

When you are ready: TAKE THE SURVEY NOW!

Many thanks to all previous participants, and to all you new-Bees for taking some time out of your busy schedule to fill out this year’s survey.

Your contribution is supporting research efforts at a national scale that are aimed to promote the health of our honey bees!


Preliminary results: 2017-2018 Total and Average Honey Bee Colony Losses by State and the District of Columbia

By now, we hope that you have taken time to reflect on this past year’s honey bee colony losses – both your own losses, as well as those experienced by beekeepers across the nation. In case you missed it, you can view our official preliminary results abstract here: https://beeinformed.org/results/honey-bee-colony-losses-2017-2018-preliminary-results/

We fared worse this year compared to the previous one, but long-term BIP efforts over the past decade suggest that we actually experienced a relatively ‘normal’ year. That means about 40% of our colonies died!

The United States is vast, and extremely diverse. Everyone can appreciate that beekeeping in the desert oases of the southwest is very different from beekeeping in the forests of New England. Hence the importance of spatially grouping our data. Each year, BIP conveys that information according to state, federal district, and territory.

This year, like previous ones, we present preliminary data for Annual, Winter, and Summer Losses. For each period and region, Total Loss and Average Loss are communicated. It’s important to understand the difference, as one type is likely more relevant to you than the other!

Total Loss treats each colony the same. In other words, one colony has one vote. This means that Total Loss is more representative of commercial beekeepers, as they manage most honey bee colonies in the country.

Average Loss, on the other hand, treats each beekeeper the same – one beekeeper has one vote. Therefore, Average Loss is more representative of the experiences of backyard beekeepers, as they vastly out-number sideline and commercial individuals.

To view region-specific data, check out BIP’s Interactive Loss Map: https://bip2.beeinformed.org/loss-map/.

There you can compare losses among years and regions, and even see how many beekeepers responded to the survey.

Figure 1 illustrates just one of the maps that our Interactive Loss Map can produce. We have also included summaries of the data in tabular formats (see Tables 1, 2 and 3).

Please note that N represents the number of beekeepers that responded from each state/district/territory. To preserve confidentiality, we have not released information for states and territories with five or fewer respondents. This means Alaska, Puerto Rico, and in some cases Hawaii, were excluded.

Yes! This is it folks. Your last chance to participate in this year’s Bee Informed Partnership’s National Survey.

Completed paper surveys are being returned daily – you only have to see Selina’s mailbox to agree!

The online survey will close at 11.59 PM on Tuesday, April 30th. That means this is your last weekend to participate.

So far we have chalked up completed online surveys from 4,307 backyard, 107 sideliner, and 25 commercial beekeepers! These are great numbers, but we are hungry! Hungry for more data!

If you have not already, please consider participating online anytime until the end of April: https://26.selectsurvey.net/beeinformed/TakeSurvey.aspx?SurveyID=LMS2018#

Cheers, from your friendly neighborhood BIP National Survey Team
