Threat factor Threat Threat Evidence base type status Fire Altered fire known current The purple eyebright is highly dependent on frequency open environments; either on a permanent or intermittent basis (DSE 2008 Murphy Downe 2006).
Low fire frequency; and reduced biomass reduction is a major threat to the subspecies as seed germination is likely to be triggered by fire (DSE 2008).
High fire frequency also constitutes a major threat to the subspecies as fire may deplete populations by killing immature plants prior to seed set (Murphy Downe 2006).
