Description
The River Oak is an evergreen tree with fine greyish green needle-like foliage that grows to a height of 10–35 m (33–115 ft) with a spread of about 10 metres (33 ft).[4][6] The trunk is usually erect, with dense rough bark. Flowers are reddish-brown in the male and red in the female.[4] Cones are small, nearly round to elongated and about 10 millimetres (0.39 in) across.[4]
Habitat
Trees are usually found in sunny locations along stream banks and swampy areas.[4] It's widely recognised as an important tree for stabilising riverbanks and for soil erosion prevention accepting wet and dry soils. The foliage is quite palatable to stock.[5] C. cunninghamiana is frost tolerant down to around −8 °C (18 °F) and is widely used effectively as a screening plant. It is useful on windy sites and is also suited to coastal areas. C. cunninghamiana has been introduced into several other countries for the purpose of agroforestry.[6]
Subspecies
There are two subspecies:
- C. cunninghamiana subsp. cunninghamiana. Large tree to 35 m (115 ft) tall. Eastern New South Wales, north and east Queensland.[4][6]
- C. cunninghamiana subsp. miodon. Small tree to 12 m (39 ft) tall. Daly River and Arnhem Land in the Northern Territory and the Gulf of Carpentaria in Queensland.[4][6]
The species has many common names including River Oak, River She-oak or Creek Oak.[5]
Invasive species
Casuarina cunninghamiana is an invasive species in the Everglades in Florida[7] and in South Africa.[8]
