This site is intended to share the results of  frequently weighing a number of beehives starting in 2010 and continuing into 2011, 2012, 2013 and 2014.  That has resulted in the accumulation of a large amount of data.

Charts have been prepared to display the net weight of each hive over the time period.  These charts portray the net weight which consists of the weight of the bees, the wax and any stores within the hive.  They exclude the weight of the wooden ware.  This provides a more accurate picture of the condition of the colony as the configuration of the hive changes.  Note: if you find the charts difficult to read, click on them and you should see a larger image.

My management practices have changed as my understanding of the weight data has increased.   That discussion is at the management changes tab.  However, this is an ongoing process.  In many cases, the results of weighing hives has shown the importance of many of the currently recommended management actions, such as, frequent re-queening, mite treatments or early starting of fall feeding programs.

What are the lessons to be learned from all this data?  That is also an on-going effort.  A discussion of the progress to date is at the Lessons Learned page.

A short discussion of the genesis of this project can be found on the About page.

This data will be updated as the seasons progress.

Your comments are most welcome.  Comments, of a general nature, can be added in the Comments section.  There is also space under the chart for each hive for making comments about that hive.   Depending on the size of  your screen, you may have to scroll down to see those.
