Herbicide is being sprayed on the weed ” pyp grass ” this month as a follow-up to work commissioned by the Northern Agricultural Catchments Council in 2012.

‘Pyp grass (Ehrhata villosa) is a serious threat to our coastal dunes,’ NACC’s coastal and marine co-ordinator Mic Payne said.

‘Deliberately introduced from South Africa in the 1960s for the purpose of binding sand, it is now one of the worst environmental weeds in WA.

‘Dunes infested with pyp grass are more susceptible to erosion caused by wind, waves and unmanaged pedestrian and 4WD access.’

There are plans for annual applications of the herbicide Verdict for the next three to four years.
