The Corymbia calophylla – Xanthorrhoea preissii woodlands and shrublands of the Swan Coastal Plain ecological community is located on heavy soils of the eastern side of the Swan Coastal Plain between Bullsbrook, and Capel. It is one of three Marri (Corymbia calophylla) dominated plant communities, which were historically probably some of the most common vegetation types on heavy soils on the eastern side of the Swan Coastal Plain.

Approved Conservation Advice for Corymbia calophylla - Xanthorrhoea preissii woodlands and shrublands of the Swan Coastal Plain
In general; use locally collected seed where available to create an appropriate canopy and diverse understorey; however; choosing sources of seed closer to the margins of their range may increase resilience to climate change.
Altered fire regimes Mediterranean ecosystems are usually fire prone and may require a particular fire regime to assist regeneration (Abbott Burrows 2003).
If an appropriate fire frequency is exceeded; however; species that are obligate seeders may not have sufficient time to flower and produce seed.
Too frequent fire can increase the risk of invasive weeds establishing within small bushland remnants such as this ecological community (Abbott Burrows 2003).
The risk of fire is generally increased by the presence of grassy weeds in the understorey; as they are likely to be more flammable than many of the original native species in the herb layer.
