Habitat and Ecology
Major system
Major habitats
Western Coastal Shale Band Vegetation
This species occurs in high altitude shale bands, at 1000-1800 m. Mature individuals are killed by fires, and only seeds survive. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is pollinated by birds.
There are no severe threats to this species, but it is potentially vulnerable to too frequent fire, as well as aseasonal fires.
