1When the conservation trust bought the highland valley, most of its ancient forest had disappeared.
2Centuries of sheep farming had stripped the hillsides bare and left the thin, fragile soil completely exhausted.
3The trust's ambitious plan was to let nature repair itself with as little interference as possible.
4Workers removed miles of old fencing so that deer could wander freely across the whole valley.
5Native trees such as oak, birch, and rowan were planted in sheltered corners where sheep once grazed.
6Within five years, seedlings began to appear on their own, carried by birds and the wind.
7The return of the trees brought back insects, and the insects brought back the birds.
8Rangers recently recorded a golden eagle nesting in the valley for the first time in decades.
9Critics argued that the ambitious project would fail, yet the landscape has quietly proved them wrong.
10The valley now welcomes thousands of visitors who want to witness what patient ecological restoration can achieve.
11For the rangers, the greatest reward is hearing birdsong echo through woods that were silent.
