semiplana, the tufted grass tree, grows on the Eyre, Yorke and Fleurieu Peninsulas, southeastern South Australia and probably midwestern Victoria.
[8] A large and prominent plant in the Australian landscape, Xanthorrhoea semiplana is a source of both food and shelter for numerous species.
A study by the CSIRO found that these grass trees generate a distinct microclimate beneath their canopies, a discovery with significant implications for wildlife.
This consistently stable environment moderates cold temperatures in winter and offers a crucial cool refuge for animals during summer heatwaves.
Additionally, the study found that larger (and therefore older) grass trees provided the greatest protection from temperature and rain fluctuations.
