Ancient woodland, Dartmoor

Black-a-Tor Copse, Dartmoor National Park


The hike in is arduous in the specific way Dartmoor demands — boggy ground, no path, the military danger zone marker on the map doing its job of dissuading the casual. I camped the night before on the hill above the copse, looking down at the treeline, planning for morning mist. The mist did not come.

Boulders softened by centuries of moss

Black-a-Tor Copse is a National Nature Reserve at 380 metres, one of the highest ancient oak woodlands in Britain. The trees are stunted by the altitude and the wind — dwarf pedunculate oaks, gnarled and horizontal in their growth, shaped by weather over centuries. The Duchy of Cornwall owns it. Forty-four moss species have been recorded here. You notice the moss before anything else.

Black-a-Tor Copse — March 2025

Delicate lichen and moss growth on weathered tree branches, Dartmoor
Lichen layering on branch surfaces

Everything in the copse is covered. The boulders are covered. The tree trunks are covered. The branches are covered, so thickly that the shape of the wood beneath is obscured, the moss forming its own topology over the original form. Some of the oak trunks are broader than they look because the moss adds several centimetres on every surface. The boulders become soft-looking, as if padded.

The West Okement runs through the lower edge of the copse. Moss-covered rocks in the streambed, gnarled oak branches overhead, water moving through and around the boulders. The sound of it is constant. The lichen on the rock surfaces is white and grey, different species layering on top of each other, each with a distinct texture.

Solitary oak on the open moorland

The morning light came without mist, flat and even. Sometimes that is what you work with. A single gnarled oak standing on the open moorland at the copse edge, white-lichened rocks beneath it, the moor extending beyond. The tree has been there long enough that the moor accommodated it.
