A Biological Investigation of an Organically Polluted Urban Stream in Victoria

Abstract

The macrofauna of Dandenong Creek, an organically polluted urban stream in Victoria, was studied. It was difficult to separate effects due to pollution from those due to other forms of interference. No true indicator species were found, but seven groups of common animals could be arranged in order of increasing pollution tolerance. Some of the difficulties of using biological systems for stream monitoring are discussed.
