Abstract

Two clusters of coastal lagoons, one near Strahan on Tasmania's west coast, the other near St Helens on the north-east coast, are the prime known epicentres of novelty and endemism in the Australian freshwater algal flora. The algae inhabiting these acid, dystrophic lagoons have a very limited distribution. Other dystrophic lagoons may have one or two, but not all, of this suite of endemics. The Strahan dune lakes, especially Lake Garcia, also have the greatest microfaunal diversity yet recorded from any Tasmanian waterbody, including several endemic species. The St Helens sites are less rich in species of microfauna, perhaps because of climatic differences or perhaps because of less intensive sampling there, but they, too, contain endemic taxa. The lagoons in both areas lie outside the formal protection of national parks, but present land management does provide a measure of protection.
