A farming family is working to boost the numbers of rare butterflies on their land.

The Duke of Burgundy butterfly has declined in numbers in recent decades, with the Butterfly Conservation Society warning “intense efforts” are needed to protect it.

Sonja and Perin Dineley, of Red House Farm on the edge of Cranborne Chase in Wiltshire, are launching a major habitat restoration scheme to boost numbers of the rare insect in their area.
