The Peel-Harvey Estuary is the most valuable future Tourism and commercial asset to the City of Mandurah, also to the Shires of Murray and Waroona. Its value lies essentially in its unique shallow water and marshland landscape accompanied by rich and varied wildlife. It has been internationally recognised through the Ramsar Treaty as a sanctuary for thousands of rare and some endangered long distance migratory bird species. Its existence is however threatened by some commercial operators and property developers who do not comprehend that the long-term future prosperity of the Region lies in conserving the delicate ecological balance of that landscape.
Part of the problem is their quest for short-term financial gain accompanied by sheer ignorance of the principles of natural landscape evolution and interrelationship of species that is embodied in the principles of natural ecology.
