Habitat:   

• rees 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.
