    Fire Fire potential future Infrequent fire regimes may pose a long term threat frequency but only if large areas are excluded from burns for periods over 20 30 years.

    More recent evidence of fires in the area demontrate that fire remains a possible stochastic event in this area; although it is unlikely to severely impact the rocky outcrops where this species is associated; especially as such outcrops are unlikely to become overgrown with shrubs to the exclusion of smaller plants (TSU 2000).
