Like other mosses, Leucophanes australe plays important roles:
- Helps retain moisture and prevent erosion
- Provides habitat for micro-organisms
- Pioneers on bare substrates, paving the way for other plants
It has adaptations for its epiphytic lifestyle and warm, humid habitat:
- Leaves with pointed tips channel water to the stem
- Rhizoids anchor it to tree bark
- Tolerates periods of desiccation
