The macro-invertebrates of Riddells and Sandy Creeks

A number of Riddells Creek Landcare families joined Sam Harrison from Melbourne Water's WaterWatch program to explore Riddells and Sandy Creeks.

We spent the day looking at and identifying the fascinating array of macro-invertebrates that live in our local creeks.

The macro-invertebrate life indicates what condition our creeks are in and we were very happy to discover that our creeks are in very good condition!
