While there are a number of endemic plants there are few animals on the higher slopes, with only nine mammals found here: four rodents, two bats, a cuscus possum, an antechinus and Doria's tree-kangaroo (Dendrolagus dorianus). Four of these are endemic: the small marsupial black-tailed antechinus (Murexechinus melanurus), western shrew mouse, glacier rat and alpine woolly rat. There are nearly 100 birds of which 28 are considered endemic or nearly so, including the vulnerable long-bearded honeyeater (Melionyx princeps), ribbon-tailed astrapia (Astrapia mayeri) and Macgregor's giant honeyeater, which although endangered generally is a cultural icon of the Ketengban people of the Star Mountains and therefore protected in some areas.
