After the 2017 Global Challenge which studied bees, students from 8th grade took care of a hive of mason bees, for the Wildbieneundpartner project (www.wildbieneundpartner.ch). These bees do not sting and do not produce honey, but they are great pollinators. The hive of Collège Champittet was one of the 124 hives in the Lausanne region, and helped saving the specie. It also contributed in the pollination of our region. In March, new bees will arrive and the project will continue.
