The Nightcap oak (Eidothea hardeniana) is listed as critically endangered under the EPBC Act. It was discovered in 2000 and has a locally restricted single population on the southern side of the Nightcap Range. 15-20 million years old fossil fruits found near Ballarat, Victoria suggest that the genus Eidothea and rainforest were historically widespread. There are also several endangered species of trees on the EPBC Act, including the southern ochrosia (Ochrosia moorei) with a range from the Gold Coast to Coffs Harbour. The Minyon quandong (Elaeocarpus sedentarius) was thought to be extinct until 1992, and is found in only three nature reserves: Nightcap NP, Jerusalem NP and Whian Whian SCA. The peach myrtle (Uromyrtus australis) has a similar range to the Minyon Quandong.
