For many years the DEP and volunteers have conducted multi-day surveys along the middle estuary foreshore for rice grass, a perennial intertidal weed which has the potential to take over wetlands and mud flats. From an infestation of approximately two hectares in 1995, rice grass has now been systematically controlled to the point that no plants have been observed since 2016.

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, including classroom materials, online resources, interpretive walks, games and sensory experience. These are focused around the key estuary habitats.
