Every year the DEP surveys the middle 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 multi-day 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 recent surveys only a few plants have been found and removed. In 2017, the DEP compiled all available information on previous surveys and control methods, and refined our survey and control methods.

Much of the text within the species area of our website was written by Veronica Thorpe, as part of the Derwent River Wildlife Guide (2000).

The DEP has developed a variety of classroom and outdoor activities focused around the key estuary habitats of tidal wetlands, salt marshes and rocky reefs. These include classroom materials, online resources, interpretive walks, games and sensory experiences.
