Other identified threats to the species are weed invasion; inappropriate fire regimes and grazing by a native moth Microlepidoptera sp. which was found to be predating the fruits and viable seed.

The species is also threatened by weed invasion as several minor pastoral weed species with aerial dispersed seed occur in low numbers at Windarling Range (DEC; 2009); grazing predation by the native moth Microlepidoptera sp.; inappropriate fire regimes and commercial flora collecting which may inadvertently damage plants (DEC; 2009).
