R54 Pteridium aquilinum vegetation
Dense species-poor stands of bracken (Pteridium aquilinum), naturally a lowland European forest fern which, when not held in check by dense shade and lacking the traditional management of cutting and trampling by cattle, readily establishes itself as a dominant in non-forest land. It spreads vigorously by rhizome extension and produces a deep litter layer. It is common in many pastoral landscapes that are less traditionally managed than before. It can also dominate in areas of burned forest.
