Question

can someone give me some facts on Daintree rainforest in Australia PLANTS

Answer 1

They preserve major stages of the earth's evolutionary history -

ancient plants representing some of the earliest land plants, the Psilotopsida (whisk ferns) and the Lycopsida (club mosses or tassel ferns);
7 ancient families of true ferns, including the Marattiaceae (giant or king ferns), Osmundaceae (royal ferns), Schizaeaceae (comb ferns) and Gleicheniaceae (coral ferns);
fern genera of East Gondwanan origins, including Polystichum (shield ferns), Leptopteris, Todea, Tmesipteris (fork ferns), Lycopodiella and Huperzia (club mosses and tassel ferns);
the ancient, fern-like cycad Bowenia spectabilis (zamia fern) and other cycads including Cycas, and the giant Lepidozamia hopei (zamia palm);
ancient conifers such as Podocarpus (plum pine or brown pine), Prumnopitys (brown pine or southern yew), Araucaria (hoop and bunya pines), and Agathis (kauri) which are living counterparts of Jurassic-age fossils (i.e., age of the dinosaurs);
12 primitive angiosperm (flowering plant) families, including small, primitive, relict angiosperm families such as Austrobaileyaceae, Idiospermaceae, Eupomatiaceae and Himantandraceae;
relict angiosperm plant families that are known as fossils from the Cretaceous (last age of the dinosaurs) including Cunoniaceae, Proteaceae (banksia and macadamia family), Winteraceae, Myrtaceae (eucalypt and lilly pilly), Monimiaceae, Rutaceae, Sapindaceae, Aquifoliaceae (holly family), Chloranthaceae, Trimeniaceae, Epacridaceae (heath family), Olacaceae and Loranthaceae (mistletoes);
153 genera in 43 families of angiosperms believed to represent the longest continuous history associated with the Gondwanan landmass.

They preserve unique, rare or superlative natural phenomena, formations or features of exceptional natural beauty –

exceptional coastal scenery unusual in the world (and Australia) where tropical rainforest extends to white sandy beaches with fringing coral reefs just offshore;
rugged mountain peaks and gorges with swiftly flowing rivers and spectacular waterfalls (e.g., Thornton Peak, Mossman Gorge, Roaring Meg Falls);
extensive vistas of undisturbed forest and valleys.
