    Past; current and future Altered fire regimes Whole population Severe It is not known what the fire response is; however; if fire frequency is increased the soil seed bank could be depleted before juvenile plants have reached maturity.

    Past Drought Whole population Severe This is a threat to the species if it occurs over a number of years.

    Population showing further major decline in numbers and health. 2003 significant drought deaths of this and other species at the site further surveys of similar sites in the Perup area no additional populations located (6 man days) 2004 significant germination adjacent to the granite; large numbers of seedlings observed ( dormancy of soil seedbank broken by extreme heat during summer ) Further surveys across the Perup area by district staff targeting this and other species.

    THREATS The main threats are associated with restricted area and susceptibility to fire; Phytophthora; drought Killed outright by fire; regenerating from seed; also killed by drought.

    Drought a potential threat especial where the plant grows on shallow soils associated with granite outcrops. 9.
