Sheep are to graze in London’s Royal Parks for the first time since the 1930s as part of a project to revive Britain’s wildflower meadows supported by Prince Charles.

From Monday, commuters crossing Green Park on their way to work will notice a small herd of rare sheep chomping through the tougher tufts of grass.

It is hoped this natural conservation method will tame the non-picturesque, dominant plants within one of the park's two wildflower meadows, allowing flowers to flourish and a rich diversity of invertebrates to grow.
