The Great Lake, covered with rushes on the peripheral part, has a shallow depth (between 0.5 and 2.80 m). Fires represent a real threat to these specific ecosystems. The Lake in 8 Rust and water Also shallow, its sandy muddy substrate, dotted with blocks of armour visible on the open banks, contrasts with the green of the plant touches. The presence of Blechnum francii in the waters and Dacrydium guillauminii on the banks, which is one of the rarest conifers on the planet, calls for vigilance. Maintaining water quality is crucial to avoid endangering these two exceptional species. Lakes Bushfire in the Lakes Plain, 1991 © B. Suprin North view East view
