The John Muir Trust are appealing for funds to buy 250 acres of Snowdonia (which would be their first holding in Wales, to add to their lands in Scotland).

"Carreg y Saeth Isaf (meaning lower rock of the arrow) is an area of native woodland, heath and bog set deep in one of Snowdonia National Park’s wildest upland areas, the Rhinogydd. The 105-hectare property stands at the entrance to Cwm Bychan, at the head of the Artro valley. The site’s high wildlife value is recognised by the number of environmental designations, and is home to greatly diverse birdlife such as redstarts, black grouse, peregrine and pied flycatchers."
