Nest boxes deployed for study on droughts and importance of water bodies for pollinators in the agricultural landscape

This week Björn and Sofia placed 56 specially designed nest boxes at 14 wetlands to study how distance from water affect nesting performance. At each wetland nest boxes were placed in gradients from the water. 7 of the 14 wetlands will later in summer be drained to simulate drought to investigate effects of catastrophic hydrological events on the pollinators.
