How to fight against the disappearance of 30% of bee colonies each year? Bees suffer from nutritional deficiencies. In the Yvelines, initiatives are being carried out to adapt cultures.
In the plain of Versailles at Saint-Cyr-L’École in the Yvelines, thousands of apple trees in bloom populate the farm of Gally and its 11 hectares of orchard. For a few days, fruit trees have visitors: the bees. Forager bees are at work, their good health is an important issue here. On the farm, five tonnes of honey are produced each year and especially this are the bees that pollinate trees.
Every spring, Bruno Gansel, the guardian of the place, makes sure that the bees are feasting. But do bees have enough flowers? To be sure, the beekeepers of Gally study their pollen. They collect it at the foot of the hives thanks to a small trap door. For three years, pollen has been regularly analyzed in the laboratory by scientists. Their conclusion is clear, the food of bees is not diversified enough.
