Unlike other eucalypts, they are sensitive to fire. To reduce fire risk they stop most plants from growing underneath them.
Brown mallets deny water to other plants by 2 means:
- Mallet leaves and bark make the soil surrounding them highly water repellent, keeping the topsoil too dry for other plants.
- Mallets intercept rain in their canopy and channel it down steeply ascending branches to their stem where it is rapidly absorbed at the base of the tree. Tannins in the bark are thought to 'thin' the water so it passes more rapidly into the soil
If you sit on the Claypit walk breakaway bench that overlooks Narrogin, you will notice that old grey-brown bark of the whipstick mallets is shedding in curly flakes to reveal smooth coppery new bark. Individual mallets vary in the process, and the normally uniform array of smooth stems has become a ragged array of shapes and colours. And to top it off, Golden orb weavers have webs there too. Oh bliss!
So abandon your bed, TV, or mind numbing social media and embark on an early morning/evening pilgrimage to meditate amongst the mallets!
