Friesland mouse plague due to modern farming

Farmers have created the ‘ideal landscape’ for field mice by developing dry pastures full of grass and with few natural enemies, the report said. Dry and warm winters also have an impact on the mouse population.

‘The mice obviously feel at home,’ researcher Klaas Talma is quoted as saying by broadcaster Nos. ‘And then they multiply, very quickly.’

Damage

The Dutch farming association LTO estimated the damage caused by mice at some €70m and said tens of thousands of hectares were affected. Dairy farmers were particularly hit because the mice ate grass roots, turning fields into deserts and ruining hay and silage crops.

Over 130 kilometres of dykes were also damaged by mice, making them more vulnerable to erosion.

Farmers can best combat the mice by working together and, for example, raising the water table in badly affected areas, the researchers said.
