Mice damage in grassland affects dairy farming in Friesland

Gosse de Vries, a dairy farmer in Friesland, Netherlands, experienced severe grassland damage from a mouse population explosion in winter 2014–2015, leading to economic losses and poor harvests. He now implements groundwater level management as a preventive measure to deter mice, aiming to protect his 80 ha grassland and 7,500 kg/year milk production from future damage.
