FRAGYLE believes the Yalgorup Lakes and their environment is a valuable and irreplaceable asset in the Peel Region. It contains living thrombolites, threatened tree species and native animals and birds. The lakes have achieved worldwide recognition by their listing as a Declared Ramsar Wetland of international importance under the Ramsar Convention.

This environment is sensitive to development and has already suffered severe degradation. As a result of human habitation, 80% of the wetlands on the Swan Coastal Plain have already been destroyed.

Any large-scale development in the remaining Yalgorup Lakes area will impose an irreversible threat to the remaining wetlands and unique ecosystem, including one of the last stands of Tuart woodland in the world.

Despite environmental studies supporting previous developments in the Mandurah/Peel region, the area has suffered great losses of local wetlands and habitats.
