Associated with Lake Augusta on the Central Plateau of Tasmania there are large parabolic dunes. This is an extremely rare feature of alpine zones and has considerable conservation value. Beyond the foredunes zonation was not particularly strong but the vegetation could be divided in to nine vegetation types. These included Orites revoluta open shrubland, Olearia algida open shrubland, Grevillea australis open shrubland, Richea acerosa-Orites revoluta shrubland, Richea acerosa heath, Helichrysum hookeri heath, Helichrysum hookeri open shrubland, fen and marsupial lawn. However, most of these vegetation types have species in common.
