David Nash tried several ambitious projects during his residency, 'Sweeping Larch Enclosure' was one of them, it would seem. It was located halfway up the stony track which climbs steeply from the visitor centre, which was formerly the beginning of the Silurian Way. Nash himself describes the piece in the 1981 guide map:

​

"Adjacent to the main footpath, planted nine larch trees at an angle on a slope which will eventually form an enclosure, each tree curving up out of the ground, giving the enclosed space a dynamic movement. Each tree fenced as protection against the red deer. Fences can be moved in ten years time."
