Rice grass

Spraying rice grass

Every year the DEP surveys the upper estuary foreshore for rice grass, a perennial inter-tidal weed which has the potential to take over wetlands and important mud flats. The survey involves a week long effort each November when DEP staff and volunteers walk the estuary foreshore at low tide. From an infestation of approximately two hectares in 1995 rice grass has been systematically controlled so that during the 2011 survey only a few plants were found and removed. However as the seeds of rice grass can survive for 6 years, ongoing monitoring is essential.
