    Threat factor Threat type Evidence base and status Fire and mechanical disturbance Non fire Potential In the absence of fire; some disturbance regimes may disturbance encourage germination and benefit the species (NSW frequency NPWS; 2002).

    Fire Potential Bertya opponens is a fire sensitive species (killed by fire) that frequency regenerates from seed (obligate seeder) (NSW SC; 2009a). and intensity Site population health and abundance may decline with too frequent fire (less than 3 years; OEH; 2014a) that does not allow plants to sexually mature (and replenish the seed bank).
