Springbrook has a rich
biodiversity that is among the highest diversity of flora, fauna and fungi in Subtropical Australia. Habitat types include Montane Sclerophyll Forests dominated by temperate eucalyptus trees such as New England Blackbutt (
Eucalyptus campanulata) and Blue Mountain Ash (
Eucalyptus oreades) both of which are near their Northern limit of distribution. Rocky outcrops and cliffs support Montane Heath shrublands dominated by Tea Trees
Leptospermum variable and
L. petersonii, Mountain Bottlebrush
Melaleuca montana and Cliff Bottlebrush
M. comboynensis. The Giant Rosette Plant
Doryanthes palmeri is present on cliffs. Many threatened and endemic flora species are present notably the Endangered Springbrook Leatherwood
Eucryphia jinksii which is endemic to the region and otherwise only found within the nearby
Numinbah Nature Reserve in northern New South Wales. Four main types of Rainforest occur on Springbrook; Dry Rainforest, Subtropical Rainforest, Warm Temperate Rainforest and small patches of Cool Temperate Rainforest on the highest peaks. The dominance and diversity of trees varies between rainforest types. Dry rainforest occurs in small patches on the Northern and Western sections of Springbrook and features hoop pine
Araucaria cunninghamii, Cinnamon Myrtle
Backhousia myrtifolia, Yellow Tulip
Drypetes deplanchei and Lace Bark
Brachychiton discolor. Subtropical rainforest favors the rich red basaltic soils of the main plateau over 100 tree species can be present however, signature species of this type include white booyong
Argyrodendron trifoliolatum, black booyong
Argyrodendron actinophyllum, Strangler Figs Ficus spp. and giant stinging tree
Dendrocnide excelsa. Much of this forest type was cleared for agriculture in the early 20th century. Warm Temperate Rainforest grows on low fertility soils derived from Rhyolite and has fewer tree species than subtropical types. Dominant trees of the warm temperate rainforest include coachwood
Ceratopetalum apetalum, Callicoma
Callicoma serratifolia and occasionally Springbrook Leatherwood
Eucryphia jinksii. Cool Temperate Rainforest is restricted to a single area above 1000m altitude near the Best of All Lookout. This forest type features Antarctic beech
Nothofagus moorei trees are likely to be thousands of years old and are covered in mosses, orchids and filmy ferns which thrive in the moist cloudy micro-climate. The highest altitude rainforests on Springbrook meet the definition of Subtropical
Montane Cloud Forests. The Springbrook plateau is very rich in native animals including; marsupials, frogs, birds, lizards, snakes and invertebrates such as Spiny Freshwater Crayfish. Paddymelon Wallabies are among the most commonly sighted marsupials but Bettongs, Bandicoots, Swamp Wallabies are also common ground dwelling mammals. Arboreal mammals include mountain brushtail and ring tailed possums and the rare Eastern Pygmy Possum has also been recorded. Frogs include the threatened Fleay's Barred Frog
Mixophyes fleayi, Marsupial Frog
Assa darlingtonii and Mountain Frog
Philoria loveridgei. Birds are abundant and diverse, the most noteworthy being perhaps
Albert's Lyrebird and a true bird of paradise the
Paradise Riflebird. Three species of Bowerbird are present being the Satin, Regent and
Green Catbird. Reptiles include the border leaf tailed gecko (
Saltuarius swainii) The
land mullet skink, Stephen's banded snake,
eastern tiger snake,
carpet python,
red-bellied black snake. Invertebrates include the Lamington Spiny Crayfish
Euastacus sulcatus and the Smaller Springbrook Crayfish
Euastacus maidae. A new species of Phasmid Stick Insect was recently discovered at Springbrook and Named
Parapodacanthus ailaketoae. Large flightless ground beetles include on the higher Springbrook plateau
Nurus perater and at lower elevations at Mt Cougal, Tallebudgera and Natural Bridge
Nurus moorei. The striking blue and red Mountain Katydid
Acripeza reticulata and Tim Tam Bug
Zopherosis georgei that resembles a chocolate biscuit have also been recorded at Springbrook. == History ==
