 Eucalyptus forests within the national park play an important role in creating habitat for many species of insects, birds and mammals.Common species are brown-top stringy bark ("Eucalyptus oblique") with pockets of white gum (Eucalyptus viminalis), blue gum ("Eucalyptus globules ) and" white peppermint ("Eucalyptus pulchella").The eyebright ("Euphrasia fragosa") is another species of particular note; the park is one of the few places the plant occurs with only three other known populations, and is the only place where it is protected in a national park or reserve.
