Phragmites australis - Norfolk reed


Phragmites australis - Norfolk reed


Location: Silverdale - North/West of Leeds. Phragmites australis is an invasive grass species that can grow up to heights of 3 meters. They prefer to grow in full sunlight conditions with poorly drained soils.


The conditions for this massive colony of P. australis are perfect for it to grow in, there is little or no shade cast from the surrounding trees (alnus glutinous and salix spp.) and its in this wet boggy terrain that it much loves to be in.


The reed has been allowed to colonise in this area of Silverdale for phytoremediation, it is the direct use of plants to stabilise or decrease the contamination in surrounding environments.
