TrachtNet EU / Honey flow in Europe |
Stand: 10/19/2022 |
| TrachtNet EU investigates honey flow dynamics in Europe. The graphs on this page visualise the summation of daily weight gains and losses of individual colonies, geographic regions and countries. TrachtNet EU is a network of more than 600 automated hive scales. The German term “Tracht” designates the sum of all forage sources: nectar, honey dew and pollen. TrachtNet was established in 2011 to monitor honey flow in Germany. In 2021, TrachtNet was expanded to include other European countries and was renamed TrachtNet EU. Countries and regions, where active scales are located, can be viewed. TrachtNet EU connects hive scales within geographic regions defined in the European NUTS classification system (More about NUTS >>>). Regional connected hive scales, so-called “virtual scales”, estimate foraging patterns within a specific geographic region based on the mean of all scales within that region. The setup allows users to compare foraging patterns of individual colonies, geographic regions, countries as well as years. TrachtNet hive-scales measure weights in 5 minute intervals with a precision of up to 10g. Weight changes (delta weights) exceeding 200g within a 5 minute interval are not considered in summations, thus eliminating beekeeper-related actions in the estimate. The corrected weight is a measure of bee activity within a specific period. Hive scale data is the property of the hive scale owners (institutions/beekeeper organizations/beekeepers). Summation data belong to the national coordinating institutions. Data and graphs are compiled for personal and/or educational use, including beekeeper organizations, to evaluate honey flow dynamics. For other use (e.g. scientific or commercial), please contact the national coordinating institutions (Link to addresses of NCI>>>).
