Pampas
Pampas is a large invasive grass originating from South America that has become widespread throughout many coastal environments in New Zealand.
Often mistaken for our native Toetoe, Pampas forms dense clumps that can grow over four metres tall and spreads rapidly through large quantities of wind-blown seed. Once established, it can outcompete native species, reduce biodiversity and alter important dune and wetland habitats.

At Waikawa Beach, Pampas poses a particular threat to restoration areas and natural dune systems where it can quickly dominate indigenous vegetation if left unmanaged.
Pampas can usually be distinguished from native Toetoe by its fluffy white or pinkish flower heads, bluish-green leaves and the distinctive spiral pattern formed by old leaf bases around the plant.
Early identification and control are important to prevent small infestations becoming much larger problems in the future.
