This is a detailed article from The Press & Journal reporting on the feasibiltiy of sheep to control giant hogweed.

On a quiet riverbank just south of Macduff lies a new secret weapon in the fight against poisonous giant hogweed: a flock of sheep.

In the shade of the trees this colony of sheep have developed a taste for the invasive plant, munching down stems until they are little more than stumps in the ground.

But the sheep didn’t get there by accident.

The Scottish Invasive Species Initiative (SISI) are at the root of this ingenious project, and over the last three years have been testing the feasibility of using sheep to control this insidious plant.

Known for its toxic sap that can cause burns, blisters and even blindness, giant hogweed is a non-native species which has been spreading uncontrollably across Scotland for decades.
