A project has launched to resurrect the 18th century Kew Ha-Ha.

A ha-ha is a sunken or blind fence, deer wall, or foss which creates a vertical barrier while preserving an uninterrupted view of a landscape.

The name comes from viewers’ surprise when seeing it.

The area outside Old Deer Sports Ground is thought to have been built as part of a landscaping project for Queen Charlotte.

But, in its current state, it could be mistaken for a ditch on the side of the road filled with bricks and overgrown plants.

Habitats and Heritage, the Royal Botanic Gardens, and Old Deer Park have raised only £150 of their £45,000 target to resurrect it so far.

Their aim is to create a wildlife corridor along the ha-ha which could attract animals such as badgers and beetles.
