Phragmites australis is Britain's tallest species of grass and, when established, forms dense stands of up to 4 metres in height. This perennial reed colonises wetland sites through its ability to form an extensive system of stron roots beneath the muddy surface in which it survives.
Phragmites australis has been traditionally harvested for its use in the thatching of roofs but stands of this this reed also play a very important role for birdlife and for the overall enhancement of wetland sites.
