Brief Abstract of the Talk
The Tamar River estuary is unique in many ways. It is Australia’s longest navigable waterway, receiving freshwater from nearly 1/5th of Tasmania’s landmass. This freshwater meets an estimated 300,000,000 cubic metres of salt water entering the system twice a day on the incoming tides. The estuary, Tamar Valley and the broader catchment supports diverse activities including heavy industry, shipping, agriculture and forestry, wineries, aquaculture, tourism, and population centres and includes significant protected areas, reserves and wetlands. All these contribute significant economic and social benefits to our region. However the Tamar River estuary has some image problems. Many in the community only recognise the estuary for the unsightly mud flats exposed in the upper reaches which impact on the aesthetics and amenity of the river. Below the surface of the Tamar is another world. This lecture presents a visual snapshot of the habitats and inhabitants that reside just below the Tamar’s surface waters that remain invisible to the broader community.
