+ Ecology

This species is native to Australia. Agathis robusta is a characteristic tree of drier rain forest where other tree species experience difficulty in attaining large dimensions. The presence of the species triggered the construction of access roads to a number of North Queensland localities. It succeeds in warm temperate to tropical regions, being able to tolerate light frosts. It prefers a deep, fertile, well-drained soil in full sun or light shade. Young plants grow better in the shelter and shade of the woodland, but require increasing amounts of light as they grow larger. In Kampala, this tree can be found at Makerere University among other places.
