The Berwyn range (Y Berwyn / Mynydd Y Berwyn in Welsh) is an isolated and sparsely-populated area of moorland located in the north-east of Wales, United Kingdom, roughly bounded by Llangollen in the north-east, Corwen in the north-west, Bala in the south-west, and Oswestry in the south-east and is famously known for its alleged 1974 UFO crash known as the Berwyn Mountain Incident.
The area is wild, remote (by British standards) and covered in a layer of heather about one metre thick, with some acidic grassland and bracken, which makes the area difficult for hill-walkers. Navigation can be difficult as the hills in the area are not very high, and are often obscured by mist or low cloud. The area supports substantial populations of upland birds including raptors, such as the Hen Harrier (Circus cyaneus), Merlin (Falco columbarius), and Peregrine (Falco peregrinus) (about 14-18 breeding pairs of each species, 1-2% of the total British population), and for this reason it is a Special Protection Area classified in accordance with the European Union's Birds Directive. Other wildlife include Short-eared Owl, Raven, Buzzard, Polecat and Golden Plover.
