A Subtidal Survey of the Tasmanian North West Coast for Tioxide Pty Ltd.

Abstract

There is definite evidence of environmental disturbance at the Tioxide sites with neasurable effects extending to Burnie and Sulphur Creek.Species richness of both animals and plants is scmewhat reduced and there is a clear indication of a change in cqnnunity structure within this region. We suggest that the causes are primarily siltation ard turbidity which reduce light levels.
