Threats Individuals of the species are threatened by insect damage; inappropriate fire regimes; firebreak maintenance; and disease; while the species as a whole is threatened by the lack of recruitment of new individuals and the restricted range of populations (CALM; 2004).
The following table lists key threat factors with supporting evidence Threat factor Threat Threat Evidence base type status Inappropriate suspected future Too frequent fire appears to be acting in concert fire intervals with drought and insect damage to leave existing adult plants under great stress and reduce recruitment (CALM; 2004).
Firebreak known current Maintenance including burning of buffer between maintenance double firebreaks has been identified as a threat to the species at two locations.
The following table lists key threat factors with supporting evidence Threat factor Threat Threat Evidence base type status Inappropriate suspected future Too frequent fire appears to be acting in concert fire intervals with drought and insect damage to leave existing adult plants under great stress and reduce recruitment (CALM; 2004).
However; when plants are stressed by drought and relatively frequent fire; for example; it has been noted that the level of insect damage increases (CALM 2004).
