The Marri – Kingia community is another one of three unique marri dominated woodlands and occurs on heavy soils on the eastern side of the Swan Coastal Plain, between Waterloo (near Bunbury) and Bullsbrook. This type has also been extensively cleared with around 150 hectares of the community remaining and many occurrences not in conservation reserves.The Marri – Kingia community is the wettest of the three marri woodland communities and is found across a number of different soil types, all of which contain a watertight clay layer that acts as a barrier to drainage of water through the soil. A number of the plant species found in the community are characteristic of seasonally wet clay soils.The community is dominated by marri (Corymbia calophylla); the shrubs Kingia (Kingia australis), honeypot dryandra (Banksia dallanneyi), pepper and salt (Philotheca spicata) and grass tree (Xanthorrhoea preissii); and the herbs Cyathochaeta avenacea, common Dampiera (Dampiera linearis), Haemodorum laxum, Desmocladus fasciculatus, semaphore sedge (Mesomelaena tetragona) and Tetraria octandra.


As with the marri – grass tree community, the most significant threat to this community is clearing as very few of the remaining areas are located within secure conservation reserves. Phytophthora dieback is also a threat as are invasion by weeds, too frequent fires and human use pressures such as inappropriate recreational use, illegal rubbish dumping and firewood cutting.
“I found the Marri – Kingia woodlands to be the most surprising community I photographed. The odd relationship between the trees and the Kingia provided a beautiful contrast when shooting. To depict the height and scale of the trees, it was necessary to use the sky as a backdrop.
I was lucky enough that the days I spent shooting gave me dramatic blues and cirrus clouds.”
