The Glass House Mountains provide islands of natural habitat for plants and animals. They conserve regionally significant areas of rhyolitic mountain vegetation that supports 26 plants that are rare, threatened or of conservation interest. The ridges, rocky pavements, scree slopes and gullies provide a variety of habitats for vegetation ranging from Eucalypt open forest to montane heaths and shrublands. The mountains also provide a habitat for many species of fauna, some of which are rare or endangered. The area now known as the Glass House Mountains National Park was first gazetted in 1954. Gazetted areas incorporated smaller parks such as Beerwah, Coonowrin, Ngungun and Tibrogargan. These smaller parks were amalgamated into the Glass House Mountains National Park in 1994.
